Location: London Workplace: OnSite Company Description We’re http://checkout.comCheckout.com http://Checkout.com. You might not know our name, but companies like eBay, Spotify, Klarna, Uber, and Sony do, because we’re behind many of the digital experiences you use every day. We are where the world checks out, enabling over 10 billion transactions yearly for more than one billion global shoppers. Whether you want to book a holiday, order food, renew a subscription, or check out online, there’s a good chance our tech powers the payments behind the scenes. Our platform helps the most ambitious businesses deliver effortless digital experiences, at scale. If you want to do career-defining work, you’ve come to the right place. We move fast, think globally, and believe great teams are built by hiring exceptional people with conviction, curiosity, and the desire to make an impact. With 20 offices across six continents and London as our HQ, we’re shaping the future of fintech – and we’re just getting started. Checkout.com http://Checkout.com will grow you faster than you expect - the deals, the pace, and the people demand it. If you've ever felt a role never let you show what you're truly capable of, this is the opposite problem: meaningful deals with some of the UK's and the world's biggest brands, real autonomy, and no ceiling on what you can take on. You'll join the Solutions team in London and own the technical side of deals from first conversation to go-live. Pre-sale, you're front and centre: positioning the platform, building demos and POCs, winning over the merchant's engineers and architects while your Account Executive drives the commercial thread. Once the deal is ready, the weight shifts: our Implementation Engineers lead the build and you stay close, so your designs survive contact with reality. You'll work on a modern, fast-moving platform with docs that answer your questions, alongside one of the strongest commercial teams in payments. People who do well here are curious by default: they pull threads, teach themselves what the job needs next, and act before anyone asks. If that's how you work, you'll like it here. What you will be doing: - Support the commercial team to position Checkout.com http://Checkout.com's products, solutions, and services - and win deals.

Champion product change and improvement. - Stay up to date with industry standards, solutions, and tech. - Be an expert on Checkout.com http://Checkout.com's platform and products. About You: If the list below looks like you, apply. Experience - 2+ years as a Sales Engineer, Solutions Architect, Pre-Sales Consultant, Implementation Engineer, or TAM. At a PSP or payments company is a bonus. - Merchant-side counts too: checkout engineering, an in-house payments team, a payments product role. - Experience in a technical, client-facing role. Payments and technical skills We need real depth in one of the two areas below and the appetite to close the gap on the other. If payments is your strength, this job will make you more technical, you'll need to want that. Strong coder lighter on payments: payments can be taught, you'll have time. Payments: - Understanding of the end-to-end payment flow and the industry's rules, regulations, and schemes. - Experience with 3DS, Network Tokenisation, Apple/Google Pay, APMs, Open Banking, or fraud-risk engines. Tech: - You can code and you're comfortable with web technologies - payments run on the web. At least one front-end (JavaScript, React, Angular) or back-end (Java, .NET, Python, Node) language. - Familiar with API-based integration (REST/JSON, Postman); can reproduce, isolate, and explain issues using logs, API responses, and tests. How you work - Clear written and verbal English; equally at home with developers and product teams as with payments, finance, and C-level stakeholders. - Commercially minded: you talk revenue, volume, and pricing, not just APIs, and push deals forward without being asked. - Highly organised; able to prioritise shifting workloads. Nice to have: - Previous exposure to RFI/RFP processes. - Familiarity with PSD2/PSD3/PSR, FCA, ISO-8583. - An additional language. - Former engineering, developer, or product manager background. - Prior roles in the e-commerce industry.

As a customer-facing, quota-carrying SC, you’ll bring together technical fluency and commercial ownership to grow your book of business. You’ll build pipeline with BDRs, engage key stakeholders, lead discovery, co-build workflow solutions live with customers, and guide opportunities through close.

Treat discovery as an opportunity to build and validate. - Orchestrate the right partners while maintaining ownership. Engage BDRs, Outcomes Architects, and technical or product specialists at the right moments, with clear context and asks, while owning opportunity momentum, customer communication, and next steps. - Drive customer value and commercial growth after signature. Partner with Outcomes Architects, guide the initial path to value with a clear adoption plan, on onboarding and ongoing multi-workflow adoption, and own expansion strategy and renewal planning. Stay accountable for translating credits sold into credits consumed, and surface risks or expansion opportunities as customer workflows mature.   SKILLS YOU'LL NEED TO BRING: - Fluency in Italian - Commercial ownership and pipeline generation. You can demonstrate how you created or advanced business, influenced customer decisions, and owned measurable outcomes. Relevant experience may come from quota-carrying sales or adjacent customer-facing roles. - Technical fluency and builder mindset.

You are excited about AI, build with new tools, and continually learn new ways of working. - Discovery, qualification, and value articulation. You can uncover customer needs, map workflows, qualify business impact and urgency, and translate what you learn into commercial outcomes, adoption plans, and clear success criteria. - Agency, urgency, and learning velocity. You set clear goals, take initiative, learn from customer interactions, and apply those learnings to improve outcomes. You bring new ideas and workflows to customers and make complex problems easier to solve. - Complex customer engagement.

Location: Remote Workplace: Remote Kit https://kit.com/ is the email marketing platform experts choose to grow their audience, deepen their relationships, and build a business around the work they love. For coaches, YouTubers, authors, podcasters, and other creatives, there isn't a better marketing hub to rely on to grow audiences, automate email marketing, and sell digital products — all within one platform. More importantly, there isn't a team more committed to helping creators earn a living. We're on a mission to help creators earn $1 billion using our creator marketing platform. We have always been 100% independent and 100% remote. We are proud to have built a product that our customers love, and we look for people who have enthusiasm and belief in our mission, vision, and values to join our team. We're also embracing AI thoughtfully — both in how we build and how we hire to ensure our team is adaptable, innovative, and ready for what's next. THE ROLE We're looking for a Senior Infrastructure Engineer II to take ownership of a large share of Kit's core infrastructure: databases, Kubernetes, version upgrades, platform tooling, and day-to-day support. You'll also build the paved paths that let engineers, non-engineers, and AI agents test and ship changes safely. The infrastructure supports creators who depend on Kit to reach their audiences and earn a living. When it's healthy, nobody notices. That's the job. This is a full-time Individual Contributor role for an experienced infrastructure engineer who likes owning production systems end to end, takes on-call seriously, leans into automation and enjoys making other people's work easier.   YOUR SUPPORT SYSTEM You'll report to Mojtaba Hosseini https://www.linkedin.com/in/mojtaba-hosseini-7a6666/, VP of Engineering at Kit. Day to day, you'll work most closely with Kris Hamoud https://www.linkedin.com/in/kristopher-hamoud-17b34665/ and Ivan Mora Perez https://www.linkedin.com/in/ivan-mora-p%C3%A9rez-ab460b45/. You'll also partner with product engineers across Kit, and with teams outside engineering who rely on infrastructure to get their work done. Once you're ramped up, you'll join a three-person on-call rotation, which works out to roughly one week in three.   WHAT YOU'LL DO - First Week: Get access to our AWS accounts, Kubernetes clusters, monitoring, and CI/CD pipelines. Read through our runbooks and architecture docs. Take part in Get To Know Yous (GTKYs) with Kris, Ivan, and the engineering teams you'll support. - First Month: Pick up day-to-day infrastructure support requests and start working through them with Kris and Ivan as backup. Ship your first improvement, such as a version upgrade or a fix to a gap in monitoring. Shadow on-call shifts. Write down what you learn along the way, especially the parts that only lived in someone's head or those that can be automated or improved. - First Six Months: Own core infrastructure areas end to end: databases, Kubernetes, version upgrades, and platform tooling. Take your full share of on-call, which you'll start by the end of your first quarter. Become the go-to person for day-to-day infrastructure questions. Find one recurring source of pages and make it go away. Ship a first paved path, such as a sandbox environment where AI agents or non-engineers can safely build and test changes. - First Year: You're the primary owner of a large part of Kit's core infrastructure, and you lead projects in it without needing direction. Uptime stays at 99.9% or better, page volume is down, and you've found real cost savings. Your paved paths are in regular use by engineers, non-engineers, and AI agents. You've built observability good enough for AI agents to handle some on-call load. You've documented your decisions so others can build on your work.     WHAT WILL S.E.T. YOU UP FOR SUCCESS   Skills - Running production infrastructure on AWS at scale, including managed relational databases, networking, and load balancing - Operating Kubernetes in production: upgrades, capacity planning, and troubleshooting - Managing infrastructure as code and maintaining CI/CD pipelines that engineers trust - Building monitoring and alerting that catches real problems early and doesn't page people for noise - Diagnosing complex, multi-service incidents calmly, then fixing the underlying cause - Cutting cloud costs through right-sizing and reserved capacity without hurting reliability - Writing clear runbooks, docs, and decision write-ups - Nice to have: experience with Cloudflare, ephemeral or sandbox environments, or email sending infrastructure Experiences - Around 7 or more years in infrastructure, platform, DevOps, or SRE roles - Owning production infrastructure for a product where downtime costs customers money - Carrying a pager for systems you owned, and making that on-call rotation quieter over time - Leading a major upgrade or migration, such as a database or Kubernetes version upgrade, with little or no customer impact - Building self-service tooling or paved paths that other engineers actually adopted - Working on a small infrastructure team where you couldn't hand problems off to a specialist Traits - You own what you run. You spot infrastructure debt and fix it without waiting to be asked, and you follow through until it's done. - You build quality into the work. Upgrades have rollback plans, maintenance windows are planned around customers, and "good enough" is a decision, not a default. - You leverage AI effectively. AI helps you increase quality and velocity where it matters most. You know when to delegate and when to dive in, while holding accountability. - You make work easier for everyone else. You'd rather build a tool or write a guide once than answer the same question ten times. - You teach what you know. You write things down so the next person, or the next AI agent, can build on your work. - You work in public. You share context and tradeoffs openly, including during incidents and when things go wrong. - You use AI thoughtfully. It's part of how you work, and you help others adopt it without creating new risks. - You remember who's on the other end. An outage means a creator's launch email doesn't go out, and that shapes how you prioritize.   WHAT WON'T SET YOU UP FOR SUCCESS - Wanting a well-defined backlog handed to you each week. Here, you'll find much of the work yourself and set priorities with Kris. - Preferring not to be on call. On-call is a core part of this role, shared across a team of three. - You are skeptical of AI’s capabilities, or conversely use AI without good judgement and accountability. - Wanting mostly greenfield architecture. A lot of this work is running, upgrading, and improving systems that already exist. - Needing layers of approval before acting.   WORKING HOURS AND LOCATION We're 100% remote with team members across the globe. We work mostly on East Coast time—so if you're based on the West Coast of the United States, Europe, or Asia, you might have a few early mornings or late evenings. We do our best to keep things reasonable, but a little time zone juggling comes with the territory. This role is part of a three-person on-call rotation, so during your on-call week you'll need to be able to respond to pages outside your usual working hours. We believe PTO should always take priority over on-call. We schedule on-call around people's lives, not the other way around. On-call is a shared responsibility, but taking time off should never be a challenge   COMPENSATION + PERKS + BENEFITS Kit has standardized salaries based on position, no matter where you live. For this role, we're hiring at our level 4 ($197,000).

Location: EMEA; Hungary; Portugal; Spain; Poland Workplace: Remote ✨ ONE PLATFORM, A WHOLE WORLD OF OPPORTUNITY The best jobs have always clustered in a handful of the world's wealthiest cities. But talent is everywhere. Oyster set out to close that gap - building a global employment platform that lets companies hire, pay, and care for brilliant people anywhere. We're proof that a high-performing culture doesn't need an office. Distributed across 60+ countries since 2020, we've built something the industry keeps noticing: - Ranked #10 of 250 on TIME and Statista's 2026 list of America's Top WorkTech Companies https://www.oysterhr.com/library/oyster-hr-named-10-of-americas-top-worktech-companies-of-2026-by-time - Named one of America's Greatest Startup Workplaces 2026 https://www.oysterhr.com/library/oyster-2026-newsweek-award by Newsweek - A G2 Spring 2026 Leader https://www.oysterhr.com/library/oyster-named-best-roi-for-any-global-employment-platform-for-g2-spring-2026 across Employer of Record, Global Employment, Multi-country Payroll, and HR Compliance - The only B Corp-certified global employment platform ~ independently verified since 2023 Two of those rankings measured our business impact from the outside. One measured how our own people feel about working here. They landed in the same place ~ because at Oyster, culture and performance aren't separate conversations. They're the same one. And we're just getting started. If you want to do the best work of your career alongside people who care as much as you do, we'd love for you to apply. THE ROLE Location: While this position is posted in a specific location, all of Oyster’s positions are fully remote and you can work from home. Forever. To create the best experience for our new hire, this role requires you to be currently based within the EMEA region. Ever built an automation that saved hours of manual work, only to discover the real problem was the process itself? That's exactly the kind of challenge you'll tackle at Oyster. We help companies employ people across dozens of countries. Behind every successful payroll cycle are hundreds of details that need to be right: benefits, expenses, time off, timesheets, salary changes, and country-specific requirements. The challenge? Not all that information arrives neatly packaged. Some comes through payroll platforms and service systems. Other details are buried in emails, contracts, receipts, attachments, or requests that need a human to make sense of them. Your job is to turn that complexity into reliable, automated workflows. You'll identify what's slowing teams down, question whether certain steps are needed at all, and build solutions that turn messy information into accurate, validated, payroll-ready data. This is a hands-on role where you'll take ownership of defined automation projects, from understanding the problem and building a solution to launching it, monitoring performance, and making improvements. You'll work with tools like n8n, Alteryx, SQL, APIs, and AI, but you won't be expected to use AI for everything. Sometimes the smartest solution is a simple rule, a better process, or preventing an issue before it happens. And because your work directly affects people's pay, getting things right matters just as much as making them faster. The goal? Less repetitive work, fewer avoidable issues, and smoother, more predictable payroll cycles across countries. HERE'S WHAT YOU'LL BE WORKING ON: - Understand what really happens behind the scenes. Map payroll processes from start to finish, including how information moves between systems, where validation and calculations happen, what needs reconciling or reporting, and how deadlines, country-specific rules, and exceptions affect the process. - Find the work worth automating. Identify repetitive tasks, manual checks, and recurring problems. Use data to assess their impact on customers and Team Members, how often they happen, the risks involved, implementation effort, and whether a solution can work across countries. - Fix the process, not just the task. Question unnecessary steps and look for ways to prevent missing information, avoidable requests, and errors before they reach payroll. - Turn expert knowledge into reliable rules. Work with payroll and operations specialists to translate complex policies and requirements into clear, documented, version-controlled logic, including effective dates and required data. - Put AI to practical use. Use large language models (LLMs) to understand requests, extract information from documents and emails, and direct cases to the right place. Build validation checks so AI-generated outputs are verified before they affect payroll. - Build automations that actually run. Create, connect, and maintain workflows using n8n, Alteryx, and LLM-based tools, integrating service platforms, payroll systems, databases, APIs, and internal tools. - Know when not to automate with AI. Choose between rule-based logic, workflow automation, AI, and human review depending on the task. Keep predictable legal and policy requirements in transparent, auditable rules, and document your decisions. - Build reliability into every workflow. Include audit trails, error handling, alerts, exception queues, and appropriate approval controls. Make sure records are never silently changed, dropped, or excluded. - Test before it matters. Build prototypes quickly, then test them against real payroll scenarios, unusual cases, and exceptions. Use shadow testing and parallel runs before introducing changes that affect live payroll. - Make payroll operations more proactive. Automate timely information sharing, payroll-input checks, the identification of exceptions that affect pay, and reconciliation between payroll and invoices. - Own what happens after launch. Track performance, measure whether automations deliver the expected improvements, troubleshoot issues, and improve or retire solutions that aren't working. - Work with the teams building the bigger picture. Partner with Product, Engineering, and Data when a problem needs a lasting platform-level solution. Turn operational insights into clear requirements and working examples they can build on. - Handle sensitive information responsibly. Apply privacy, security, and responsible-AI standards, especially when working with health, leave, or other sensitive payroll information. Make sure uncertain or compliance-sensitive cases reach the right people for review. You'll likely enjoy this role if you like getting into the details of how things work, spotting opportunities others miss, and building solutions yourself. HERE'S THE EXPERIENCE WE'RE LOOKING FOR: - 3+ years of relevant experience in operations automation, process improvement, business or process analysis, payroll operations, internal tooling, or a similar field. - You've built automations yourself. You've taken workflows into production using tools such as n8n, Alteryx, Make, Zapier, Power Automate, or similar, and have experience keeping them running. We're looking for someone who builds, not just someone who designs or documents solutions. - You've used LLMs to solve practical problems. You know how to turn unstructured text or documents into usable data and can recognise when a simpler, rule-based solution is the better choice. - You're comfortable connecting systems. You've worked with APIs, webhooks, and integrations to get different tools and data sources working together. - You know your way around SQL and data. You can investigate, combine, validate, and analyse information from multiple sources, even when the underlying data is complex. - You can bring structure to messy processes. You're able to turn inconsistent inputs, unusual cases, and complicated requirements into clear rules and data requirements. - You take accuracy seriously. You understand the importance of checks, controls, and investigating discrepancies, particularly when errors could affect someone's pay. - You can explain technical ideas clearly. You're comfortable working with non-technical colleagues, asking the right questions, and constructively challenging requests when automation isn't the best answer. - You take ownership beyond the build. You can move from identifying a problem through implementation, testing, launch, monitoring, and ongoing maintenance. YOU DON'T NEED TO TICK EVERY BOX BELOW, BUT ANY OF THESE WOULD HELP YOU GET UP TO SPEED: - Experience with multi-country payroll, Employer of Record (EOR) services, finance operations, or HR operations. - Understanding of payroll concepts such as gross-to-net calculations, payroll cut-offs, statutory deductions, taxable benefits, expense taxability, and reconciliation. - Experience building tools that validate or reconcile payroll or financial data. - Familiarity with Zendesk or other customer service platforms and their automation capabilities. - Hands-on experience with n8n or Alteryx specifically, although comparable automation tools are equally relevant for the core requirements. - Experience with prompt design, AI agents, or retrieval-augmented generation (RAG) workflows. - JavaScript or Python skills for data transformations. - Experience measuring operational improvements through metrics such as first-time accuracy, processing time, service-level performance, or error rates. THIS MIGHT NOT BE RIGHT FOR YOU IF... - You'd rather design automation strategies or workflows than build, launch, and maintain them yourself. - You prefer using AI for every problem, even when a straightforward, auditable rule would be more reliable. - You measure success mainly by speed or the number of automated tasks, rather than accuracy, proper approvals, and resolving discrepancies. - You don't enjoy digging into complicated processes, inconsistent information, or country-specific exceptions. - You're looking for full ownership of company-wide automation strategy. Here, you'll own clearly defined projects and work closely with operational specialists and engineering teams on broader changes.
