Location: Remote This role may require in-person interview/s in Austin, Texas About Osano: Osano is an innovative B-Corporation built around a simple belief: privacy is a fundamental right. Since day one, we’ve been focused on giving modern enterprises the ability to innovate quickly, stay competitive, and earn customer trust by respecting data privacy and complying with consent guidelines. Our products help organizations operate confidently in a rapidly evolving regulatory and technological landscape. About The Role: We're looking for a product-minded Senior Software Engineer to own meaningful parts of the Osano platform end to end, from shaping a problem with Product to running the result in production. This role is for an engineer who treats AI tooling as a real force multiplier. You use coding agents and AI-assisted workflows to explore unfamiliar code faster, ship more and remove repetitive work. You also have the judgment to verify everything that goes out under your name. We want someone whose impact goes beyond what they write by hand, and who helps the engineers around them do the same. You'll work across our React front end, Node.js services, PostgreSQL data stores and AWS infrastructure. You'll partner closely with Product, Design, QA and Security. This is a remote role. You must be based in, and authorized to work in, the United States. What you'll do: Build and ship product, end to end Lead multi-sprint projects from design through rollout: turn a loosely defined problem into a plan, break it into work that you and others can action, and deliver close to estimate. Design systems that hold up, and write design docs and decision records that weigh the alternatives. Partner with Product on scope: propose MVP cuts, phasing and tradeoffs, and measure whether what we shipped actually helped customers. Engineer with AI to multiply your impact Use AI coding agents and assistants across the whole development lifecycle: exploring codebases, scaffolding, writing tests, debugging, refactoring, migrations and code review. Stay accountable for every line you ship. You understand and can explain AI-generated code, and you know where AI shouldn't be trusted. Turn repetitive engineering work into automation: scripts, agent workflows, and checks that save your team time every week. Share what works: help define how our teams use AI tools, and how we review and verify AI-assisted work. Use AI responsibly. Customer and personal data stays out of AI tools except through approved, privacy-safe paths. This is non-negotiable at a privacy company. Own what you ship in production Build observability, feature flags and rollback paths into your work from the start. Take turns on our triage and on-call rotation. Lead incident response for your team's systems, and see postmortem follow-ups through to completion. Identify tech debt, size it, and make the case to get it into the plan. Build with privacy and security by design Apply data minimization, residency, retention and access controls to the systems you design, especially those that handle customer and personal data. Write secure code and fix vulnerabilities in your area as part of normal work. Raise the bar and grow others Give code and design reviews that change outcomes, not just approvals. Mentor engineers earlier in their careers, and make your team better at testing, reviewing and operating software. Interview candidates and help us hire well. About you: Delightful Experience. You care about the customer problem, not just the ticket, and you push for what actually helps. Own Your Impact. You take full responsibility for outcomes, from the first design doc to how the feature behaves in production at 2 a.m. Stronger Together. You put team success ahead of individual wins, give direct and kind feedback, and treat documentation and async communication as first-class work. Growth Mindset. You're curious and keep learning, especially as AI changes how software gets built. You're excited about what it can do without overselling it or ignoring its limits. You're comfortable with ambiguity and create clarity for others through good design and clear writing. Must-haves: Typically 5+ years building and shipping production software. We care more about what you've owned than the number of years. A track record of leading multi-sprint projects from design to production in a team setting. Strong JavaScript/Node.js and React experience, and solid relational database skills (PostgreSQL preferred). Strong system design fundamentals: data modeling, API design, and naming the tradeoffs. Experience owning production systems : on-call, incident response, observability. Hands-on, day-to-day use of AI coding tools such as Claude Code, Cursor or Copilot, with concrete examples of how they made you or your team more effective, and how you verify their output. Experience mentoring other engineers. Strong written communication in a remote, async environment. Nice-to-haves: AWS experience (ECS/Fargate, Lambda, S3, RDS), especially multi-region or data-residency work. Privacy, security or compliance-sensitive B2B SaaS (GDPR, CCPA, SOC 2). Building AI-powered automations, agent workflows or LLM-based product features. Data and analytics tooling (Redshift, Athena) or event-driven architectures. CI/CD, preview/ephemeral environments, end-to-end testing (Cypress). How we work: Fully remote, with at least four hours of overlap each day with your team's core hours. Collaborative and video-on for meetings, and async-first for everything else. Bring people in when they are needed and share what you’re working on with the team. Regular 1:1 checkins with your manager, with a focus on growth conversations. Why Us: We're a welcoming team that's dependable, curious, moves fast, and full of talented people We're a B-corporation with a mission that matters, in a high-growth space with significant potential You'll have access to our training program, well-defined career paths, and a leadership team that values professional development Benefits: Competitive-pay compensation and ownership interest/equity Unlimited paid time off, plus a requirement to take at least two weeks off per year We're a Best Place for Working Parents and offer paid parental leave for all new parents Osano sponsors individual premiums on base plans at 100% and dependent premiums at 50% for Medical, Dental, and Vision insurance via Aetna A fully and permanently remote company, so you can work from anywhere in the U.S. Receive a MacBook and $600 to craft your home workspace Annual company trip designed to foster connection, creativity, and fun Mental health benefits with free memberships to mindfulness and talk therapy services A Bit More About Osano: Osano is a leading data privacy platform that helps organizations quickly and confidently comply with laws like GDPR, CCPA, and other global privacy regulations.

Location: New York; Charlotte; Atlanta; Washington D.C.; Boston Workplace: Remote WHY PRODUCT ENGINEERING AT LANGFUSE Your work will have an outsized impact. Everything you build is open source (MIT-licensed) and immediately visible. Langfuse has 35,000+ GitHub stars and our SDKs are downloaded more than a hundred million times per month. When you ship a new feature the community notices in GitHub issues, on X, and in our community channels. Product engineers at Langfuse are the people who deliver new features end-to-end to our users. You own the product thinking from understanding the user problem to deciding what to build to shipping the solution. You will also have direct exposure to how cutting-edge LLM applications are built. The users you serve are some of the best and most ambitious software engineers leveraging Langfuse to improve their applications. Deeply understanding the problems they solve will help you design the best possible product and along the way makes you an expert on LLM engineering yourself.   YOU WILL GROW AT LANGFUSE BY - Own features end-to-end: from talking to users, to writing the spec, to shipping the code and docs, to writing the changelog post https://langfuse.com/changelog with your name on it. To give you a sense: recent features a single engineer owned include the Langfuse for Agents https://langfuse.com/changelog/2025-11-05-langfuse-for-agents release (new trace views, agent graphs, semantic span labels), the TypeScript SDK v4 https://langfuse.com/changelog/2025-08-28-typescript-sdk-v4-ga rewrite on OpenTelemetry, and managing dashboards via API/CLI/MCP https://langfuse.com/changelog/2026-07-17-dashboard-and-widget-operations-in-api. - Work across the full stack: and we mean full. Our surface area is wide: React frontend, Next.js backend, ClickHouse analytics, Python and TypeScript SDKs, public docs, Terraform modules, and more. You'll touch whatever the feature needs. One week you might be writing a new ClickHouse query for cost analytics, the next you're designing an SDK API, the next you're building a new rust worker for faster data processing. - Talk to users constantly: jump on calls, respond in community channels, and route support requests. At Langfuse, support is how we build conviction about what to build next. Our handbook says it best: support by engineers is a core value proposition. - Write public documentation about the features you own. At Langfuse, docs are product. - Ship publicly during Launch Weeks: we've run four Launch Weeks https://langfuse.com/blog/2025-10-29-launch-week-4 so far, dropping a new feature every day for a week. Engineers present the features they built to the community.   WHAT WE’RE LOOKING FOR - Someone who has built features or even entire products from scratch end-to-end - Experience building and shipping user-facing products end-to-end, ideally in TypeScript/React and with exposure to data-intensive backends - Someone who can manage projects themselves. You know how to develop strong conviction about what to build and how to ship it. - Taste for great developer experience: you care about API design, UI details, and clear documentation - Interest in open source software and genuine excitement about talking to developers about their problems - Thrives in a small, accountable team where your output is visible and matters - CS or quantitative degree preferred Bonus points: - Experience with ClickHouse, analytics databases, or building complex data visualizations - Former founder or early startup experience - Contributions to popular open source projects - ML/AI background or familiarity with the LLM framework ecosystem No candidate checks all boxes. If you feel you are a good fit for this role, please go ahead and apply.   PERKS - Flexible work environment - ClickHouse is a globally distributed company and remote-friendly. We currently operate in over 25 countries. - Healthcare - Employer contributions towards your healthcare. - Equity in the company - Every new eligible team member who joins our company receives equity. - Time off - Flexible time off in the US, generous entitlement in other countries. - A USD$500 Home office setup if you’re a remote employee. - Global Gatherings – We believe in the power of in-person connection and offer opportunities to engage with colleagues at company-wide offsites.
