Location: Tbilisi; Yerevan; Belgrade; Novi Sad, Vojvodina; Poland; Portugal Workplace: remote About Provectus Provectus is an AWS Premier Partner and an Anthropic Strategic Partner, working at the frontier of applied AI. We help enterprises turn Claude, agentic systems, and their own data into measurable business outcomes — through bespoke applications, managed services, and advisory engagements. With offices in North America, LATAM, and EMEA, we partner with clients worldwide. Our work centers on two verticals — Financial Services & Insurance and Healthcare & Life Sciences — where we deploy five pre-built AI Blueprints: Submission Flow, Portfolio Lens, Asset Flow, Revenue Flow, and Evidence Lens. Each Blueprint rebuilds a critical business process front to back, shipped from working code and tuned to a client's specific book, regulators, and operating posture. Our team holds 100+ AWS certifications, is Claude Code certified, and co-delivers Anthropic's Agentic SDLC program, Cowork Activation, and AI Blueprint engagements. Where this role sits: You will work in a small, senior pod alongside an FDX; our delivery arc is Sprint → Enable → Realize: Forward Deployed Executive (FDX) owns the commercial relationship and the business outcome. Works alongside the client's leadership or C-suite level to move the client's KPIs — revenue growth, cost reduction, risk reduction. Forward Deployed Engineer (FDE) embeds with a client to change how that client operates. You own the method; nobody hands you a ticket. You map the client workflow as it actually happens, identify the business problem underneath it, build a working AI solution, present to the client in the language of outcomes, and transfer it. Provectus maintains industry Blueprints — working systems that have already shipped for a client in the same industry — so you begin from running code and tuning it to this client's specific book, regulators, and operating posture. You will be measured on whether the Business Unit's number moved, not on hours or scope delivered. Requirements: Mindset Proactive and self-directed; identify problems before they're handed to you Comfort with ambiguity and ownership. Engagements start underspecified by design. Closing that gap is the job B2+ English, comfortable collaborating across distributed, multicultural teams Client Engagement You are willing to spend time understanding and doing someone else’s job on the client's side before you write a line of code Credible with senior stakeholders — you can hold a redesign conversation with a BU head and a scoping conversation with a CTO, presenting outcomes to them You can produce a scoped, phased delivery plan with clear deliverables, dependencies, and risks — and estimate what it will cost to build and to run Technical depth 7+ years building and running production systems. Solid AI/ML foundations. You understand what the models do well enough to reason about failure modes Designed and shipped to production LLM applications and agentic workflows — not demos, not POCs, not notebooks Agentic orchestration: multi-step workflows, graph-based orchestration, tool use, state management, and recovery from partial failure Experience with LLM APIs (Anthropic, AWS Bedrock, or OpenAI) and agent frameworks. Experience building and optimizing RAG systems in production Strong engineering fundamentals — dropped into an unfamiliar codebase or language, you’re productive. Python and/or TypeScript proficiency; depth matters more than stack. Experience in making and defending architectural trade-off decisions Hands-on AWS production depth: Bedrock, Bedrock AgentCore, Lambda, ECS, S3, SQS, ECR, or similar. GCP or Azure is a plus Cloud-native delivery: containers, ECS or Kubernetes, IaC, and CI/CD applied to AI pipelines You evaluate. You have built or owned an eval suite for a non-deterministic system, and you can explain what you measured, how you produced ground truth, and what gated a release Model and agent monitoring, drift detection Cost and latency discipline: model tiering, caching, and the ability to say what a workload costs to run before it runs Hands-on production experience with the Claude ecosystem —  Claude Code, CLAUDE.md, hooks, skills files.  Spec-driven development — writing the intent, constraints, and acceptance criteria before you let an agent build — is a strong plus MCP: you can say why an agent would prefer it to a REST integration. Having authored a server is a plus What you’ll do: Take the seat Sit with the client and the Forward Deployed Executive at the start of an engagement. Learn the function from inside, not from a requirements doc, and redesign the function from first principles. Reach working fluency in a new domain — insurance underwriting, healthcare revenue cycle, asset flow. Build Design and ship production GenAI systems into the customer’s environment (cloud-native data, LLM-based, and agentic AI solutions). Implement and optimize RAG systems for production use cases Build the evaluation harness before you build the feature. Define what working means, instrument it, and let the evals drive the design. Write production code across the stack — AI, backend services, data pipelines. We choose tools to fit the customer. Take systems to production on AWS (GCP or Azure where the customer requires it): containerised, CI/CD, automated testing, monitoring, and maintainable after we leave. Hand the system over to the client. Start from the blueprint, and feed the blueprint. What you learn in the field becomes the baseline the next engagement starts from. Lead architecture reviews, produce technical design documents, and contribute to standards. Mentor engineers and share knowledge across the team. Own the outcome. Work in a pair with a FDX who carries the Business Unit’s KPIs. Your work is measured against the same number. Own the technical direction of technical proposals and scoping. Drive adoption. Change management is part of the engineering job here. Be credible with the customer’s engineers and their executives. Shape what we commit to before we commit to it. Nice to Have: Prior experience as a founder, CTO, or engineering leader who has chosen to return to individual contribution Experience in one of the industries: financial services, insurance, healthcare Consulting, professional services, or other embedded customer-facing delivery A2A: you can explain agent-to-agent interoperability AWS and Claude Code Certifications CI/CD pipeline experience (GitHub Actions, GitLab CI) Experience in an additional language (Go, TypeScript, or Rust) Experience with Apache Spark, Apache Airflow, Kafkа What We Offer: The chance to shape how leading enterprises across LATAM, Europe, and North America adopt AI, from strategy through first deployment A forward-deployed model working in small, senior teams alongside Principal Architects and Forward Deployed Engineers A growing AI delivery practice where you help build the tooling and frameworks, not just use them Remote-friendly culture Internal training programs with full support for Claude, AWS, and other professional certifications, conference attendance Career growth; we actively develop our engineers Access to the latest AI tools and premium subscriptions Long-term B2B collaboration Private medical insurance or a budget for your medical needs Paid sick leave, vacation, and public holidays Equipment and all the tech you need for comfortable, productive work How we hire:   Intro conversation. The role, your background and aspirations, tech questions. Technical interview with live engineering sessions. Real problems, your own editor, you may use an LLM assistant  HR Interview. Soft skills and expectations HM interview. Tech questions; a live engineering session is also possible

Deep familiarity with new user growth, referral and virality mechanics, activity and reward systems, and the client-side architecture behind core business conversion flows. Strong expertise in mobile attribution design and evolution — hands-on experience with attribution platforms and solutions, and proven ability to drive attribution data into anti-fraud, channel revenue sharing, and ROI evaluation applications. Proficient in AI-assisted development — able to independently build and maintain personal AI engineering workflows, not just use AI tools ad hoc. Data instincts: you think in funnels, know how to instrument what matters, and use metrics to drive decisions. Outspoken and proposal-driven — you come to the table with a point of view, push back when you disagree, and bring data and a counter-proposal rather than just flagging concerns. Strong cross-functional communication — comfortable working with Product, Business Development, and local markets to align on goals and hold the line on engineering quality.

Location: Tbilisi; Warsaw; Minsk; Chișinău; Belgrade Workplace: remote About the Role: BOSS Revolution helps millions of people around the world stay connected with family and friends through international calling, mobile top-up, and money services. As a Senior Flutter Developer on the DTC Calling team you'll build and evolve the flagship BOSS Revolution app. Your main direction is Product-Led Growth (PLG): the referral program (Refer-a-Friend), onboarding and activation funnels, promo and reward mechanics (loyalty and subscription offers, first-transfer and recharge bonuses, upsell offers), and the experiments that decide which of them ship. It is the main direction, not the only one: you'll take on any work the team owns — home, calling, money-transfer and top-up flows, subscriptions and payments — as the roadmap requires. You'll work in one of the largest Flutter codebases in production — a monorepo of 100+ internal packages, feature-first clean architecture, and a strong engineering culture around code quality, testing, and automation — and ship in short, instrumented iterations: hypothesis → flag → variant → metric → decision. The app also carries a native calling stack (SIP/VoIP on Android and iOS); experience there is welcome, not required. What You'll Do: Growth (main direction) Build growth mechanics end-to-end : referral flows (invite links, deferred deep links, reward tracking), onboarding & activation funnels, promo/reward dialogs and offer surfaces, in-app surveys — from a PRD with a success metric to a measured result in production. Run experiments as a habit : ship behind feature flags, wire variant assignment from our remote-config / A/B service (fixed-split and multi-armed-bandit tests) and Firebase Remote Config, tag events with test and variant, watch guardrail metrics, and remove the flag once the test is decided. Instrument and validate analytics : define and implement Amplitude/GA events and properties, keep the event taxonomy clean across releases, verify events before launch, and read funnel dashboards together with the PM and data team. Render server-driven promo content : integrate with our in-house campaign platform — targeted campaigns, remotely configurable copy and creatives, layout updates pushed from the backend in real time — with versioned fallbacks, so campaigns launch without an app release. Integrate third-party growth SDKs : attribution (AppsFlyer), Braze (push, content cards), ads (AdMob / AppLovin), payments and KYC vendors — mostly through Flutter plugins, occasionally extending them in Kotlin/Swift via platform channels. Across the app and team Ship product features beyond growth : home screen, calling flows (Flutter UI over the native SIP stack), money-transfer and top-up flows, subscriptions and payments (card and wallet flows, Google/Apple Pay), country selection, chat and social features, performance and tech-debt work — the same standards, a different surface. Own features within our architecture : feature-first clean architecture, Bloc/Cubit state management, repositories, immutable state, Result-based error handling; migrate legacy Provider/ViewModel code in the modules you touch (e.g. the referral module) to the current patterns. Work at real scale : a Melos-managed monorepo with 100+ packages, strict dependency hierarchy, code generation (json_serializable / freezed), a shared design system, and a 90% diff-coverage gate enforced per package in CI (bloc_test + mocktail). Keep releases healthy : trunk-based development, ~2 releases a month through GitHub Actions and Fastlane, Crashlytics plus product-metric monitoring, staged rollouts and kill-switches for risky changes. Collaborate cross-functionally : with product managers (growth and core product), backend engineers (campaign, config and A/B services), data & BI, marketing (Braze campaigns) and QA — and push back on asks that cannot be measured. Use AI-assisted development as part of the everyday workflow: Cursor / Claude Code / Copilot with in-repo prompts, agents and MCP integrations. We're Looking For: 5+ years building mobile apps, including 3+ years with Flutter in production. Strong Flutter/Dart: Bloc/Cubit or comparable structured state management, async programming and isolates, code generation, dependency injection, clean architecture and modularization. Hands-on, experiment-driven product development: feature flags and remote config (Firebase Remote Config, LaunchDarkly, Statsig, GrowthBook or an in-house service), A/B rollout mechanics (staged rollout, sticky assignment, kill-switch) and analytics instrumentation (Amplitude, Mixpanel, GA or similar) — including knowing how your experiments ended. Deep linking, including deferred deep links and App Links / Universal Links setup; understanding of attribution flows. Working knowledge of native Android (Kotlin) and/or iOS (Swift) at the level of platform-channel and SDK integrations. Strong testing culture: unit and bloc tests with mocked collaborators, deterministic tests, comfortable working under coverage gates. Full lifecycle experience: Git, CI/CD (e.g. GitHub Actions), code signing, store deployment, post-release monitoring. Product mindset: can work from a PRD with success metrics, propose instrumentation and guardrails, and explain trade-offs to non-engineers. English: Upper-Intermediate or higher. It Would Be a Plus: Time on a dedicated growth or monetization team: referral programs, onboarding optimization, paywalls / subscriptions, retention work, multi-armed bandits. Attribution and marketing SDKs by name: AppsFlyer, Kochava, Adjust, Branch; Braze, Iterable, CleverTap. Server-driven UI or remotely configurable content systems.

Location: Chișinău, Chișinău Municipality, Moldova About the Role Join Alvys, an early-stage company transforming the $800B US freight industry. As a Senior Full-Stack Engineer, you’ll build and operate key parts of our cloud-native SaaS platform—spanning backend services, frontend applications, and cross-cutting system components. You will own features end-to-end, partner closely with engineering, product, and design, and help advance both the technical foundations and user experience of our products. Industry Insight Transportation logistics is massive, fragmented, and still largely underserved by modern software. You’ll be helping define the future of how freight moves by contributing to automation, operational intelligence, and workflow modernization at scale. About Alvys Alvys is building a multi-tenant SaaS platform that powers modern transportation operations. We combine deep industry knowledge with strong technical execution to bring clarity, automation, and reliability to one of the world’s most essential industries. Our Principles Engineering Principles: Build for Real-World Impact — Our users rely on Alvys to solve real problems, not abstract ones. Every feature we ship is designed to reduce friction, increase efficiency, and drive tangible results for the people moving freight every day. Extreme Ownership and Empowerment — Ownership extends beyond building—it means being accountable for quality, reliability, and customer impact. If it's in production, it's yours—bugs, uptime, and results. Technology Debt is Strategic, Not Accidental — Technical debt is a strategic choice, not an oversight. We incur it deliberately when it unlocks speed, learning, or market advantage. Our architecture remains clean, maintainable, and scalable as we grow. Simplicity Scales; Complexity Costs — Logistics is inherently complex, but our technology shouldn't be. We prioritize simplicity in our architecture, leveraging modularity and well-defined service boundaries to reduce cognitive load. Radical Transparency — We democratize data and make it accessible across all functions to drive alignment and decision-making. Transparency also means feedback—we systematize constructive feedback loops to ensure growth. Engineering Culture: Move Fast, Learn Fast — Speed is our advantage, but we move fast intentionally. We bias for action, assume positive intent, and treat every mistake as a learning opportunity. Own the Outcome — Every engineer owns outcomes, not tickets. We take responsibility end-to-end—identifying problems, delivering solutions, and ensuring they last. Engineering-Led, Customer-Driven — Engineering leads by shaping technical strategy, but never in isolation. Designers, PMs, and Engineers share context and decisions, keeping customer outcomes at the center. Pragmatism Over Purism — Elegant code matters, but business impact matters more. We choose solutions that scale, are maintainable, and solve real customer problems—not theoretical ones. People Over Heroics — We don't reward burnout or always-on behavior. Sustainability is a feature, not a luxury. If someone needs to slow down, unplug, or take care of life outside work—that's expected.

Location: Remote, Global ABOUT SUPABASE Supabase is the Postgres development platform, built by developers for developers. We provide a complete backend solution including Database, Auth, Storage, Edge Functions, Realtime, and Vector Search. All services are deeply integrated and designed for growth. ABOUT THE ROLE We're looking for Engineering Managers to lead engineering teams across Supabase. Teams range from developer-facing surfaces, core backend services, Platform, EngOps, and Databases. This is a single pipeline for engineering management. As we get to know your background, we'll match you to the team where your experience and interests overlap most strongly. The Engineering Manager is a people, delivery, and technical role. Although we don’t expect managers to contribute to code directly, we do expect you to participate in design discussions and to be involved in setting the bar for engineering quality and best practices. This is a new role at Supabase. We've historically optimised for technical excellence on every axis, including leadership. As our engineering org grows, people leadership has become just as critical, and the Engineering Manager role exists to reflect that. You'll be shaping what this role looks like from day one. WHAT YOU'LL BE RESPONSIBLE FOR Team & People - Build a healthy, high-trust team culture in a remote-first, globally distributed environment. - Run 1:1s, performance management, career development, and onboarding for your direct reports. - Handle people admin (leave, time off, etc.) for your team. Hiring - Own the hiring plan for your team and act as Hiring Manager. First round of interviewer for all roles on the team. - Partner with Talent Acquisition to source, interview, and close strong candidates. - Contribute to headcount planning, org design, and the evolution of engineering leadership at Supabase. Delivery & Roadmap - Own the team's roadmap and project management (Linear), driving accountability and clear milestones. - Manage workflow intake and Slack triage. These are the team’s primary inboxes for cross-team requests. You decide what gets routed where, prioritized, or pushed back on. - Own the team's weekly updates and keep stakeholders aligned without creating overhead. - Organize effort against support tickets and maintain the team's SLO. - Surface risks, dependencies, and tradeoffs early and clearly to leadership. Incident Commander - Train as an Incident Commander. Drive coordination, resolution, and post-incident follow-up. - Lead blameless post-incident reviews YOU MIGHT BE A GOOD FIT IF YOU - Have 5+ years of engineering background, with enough depth to be credible with engineers building complex systems. - Have 3+ years managing remote engineering teams. - Have managed engineering teams at a cloud, SaaS, or developer tools company. Experience with developer tools or databases is a strong preference, but we'll consider any sufficiently technical background where you can demonstrate the ability to ramp on a new domain. - Have managed remote, globally distributed teams that work asynchronously across disparate time zones. - Are technical enough to be credible with strong engineers, but genuinely passionate about people management. This is the work you want to do, not a track you're settling for. - Build psychological safety and a feedback culture: you give feedback often and in the moment, ask for it back, and create space for the team to do the same. - Operate as a multiplier. Focused on helping individuals achieve more than they could alone, not on being the best technical voice in the room. - Coach rather than direct. Remove blockers, connect people to context and resources, and trust your engineers to own how the work gets done. - Have a real track record of performance management and can speak to specific examples of difficult conversations and how you navigated them. - Are comfortable with ambiguity and capable of building structure where there isn't much. - Communicate clearly and write well. You're default async, default written, set context proactively, and surface risks early. - Are collaborative, low-ego, and adaptable. You thrive working with high-autonomy, senior ICs who have strong technical opinions and don't need to be the smartest person in the room. WHAT WE OFFER - Fully Remote We hire globally. We believe you can do your best work from anywhere. There are no Supabase offices, but we provide a WeWork membership or co-working allowance you can use anywhere in the world. - ESOP Every team member receives ESOP (equity ownership) in the company. We want everyone to share in the upside of what we’re building together. - Tech Allowance Use this budget to set up your ideal work environment—laptop, monitor, headphones, or whatever helps you do your best work. - Health Benefits Supabase covers 100% of health insurance for employees and 80% for dependents, wherever you are. Your wellbeing and your family’s health are important to us. - Annual Off-Sites Once a year, the entire company gathers in a new city for a week of connection, collaboration, and fun. It’s a highlight of our year. - Flexible Work We operate asynchronously and trust you to manage your own time. You know what needs to be done and when. - Professional Development Every team member receives an annual education allowance to spend on learning—courses, books, conferences, or anything that supports your growth. ABOUT THE TEAM Supabase was born-remote and open-source-first. We believe our globally distributed team is our secret weapon in building tools developers love. - ~400 team members - 60+ countries - 20+ languages spoken - Over $1B raised (including our $500M Series F) - 540,000+ community members We move fast, build in public, and use what we ship. If it’s in your project, we probably use it in ours too. We believe deeply in the open-source ecosystem and strive to support—not replace—existing tools and communities.
