About the teamOpenAI’s Forward Deployed Engineering (FDE) org sits at the intersection of product, engineering, research, and go-to-market. We take frontier platform capabilities into the real world with design partners, turning raw customer signal into shipped software, repeatable patterns, and product direction.This group is an innovation loop within FDE. We sprint on a small number of platform bets at a time: identify high-signal problems emerging across deployments, build early versions quickly, validate them with design partners, and work with our core engineering and product counterparts to put successful bets on a scalable path. When a capability is ready to scale, we help transition ownership — and then move on to the next frontier.About the rolePlatform Incubation Engineer is a role within Forward Deployed Engineering (FDE) for strong software and ML engineers who want to build new platform capabilities from scratch, grounded in real customer deployments.You’ll join a small team working in pods against platform bets rather than a single long-running account. You’ll collaborate closely with customer-tagged FDEs and partner teams across engineering and product to: (1) incubate early versions, (2) validate them with design partners through short deployments or pilots, and (3) drive adoption by making the capability durable, usable, and ready to scale. You should expect to be customer-facing when it matters – pitching, rollout planning, debugging, and learning directly from what breaks in production – but your primary charter is to turn frontier signal into reusable platform capability.This role does not require travel. It is based in San Francisco or New York. We use a hybrid work model of 3 days in the office per week. We offer relocation assistance. Travel is optional-by-project and typically <10%, with occasional spikes for key embeds or launches.In this role you willArchitect and build new platform capabilities: turn frontier customer signal into concrete designs, implementations, and APIs that become part of the OpenAI platform.Incubate platform bets end-to-end: take ambiguous problems, form a crisp hypothesis, ship an initial capability, and iterate quickly based on what breaks in real usage.Embed with design partners to learn fast: get close to production constraints, run deep technical discovery, and translate needs into product and platform requirements.Partner with customer-tagged FDEs in the field: deploy and debug together, capture repeatable patterns, and convert field learnings into platform improvements.Design and run pilot programs: define qualification criteria for early adopters, stand up internal/external alphas, and use pilots to harden both the platform and the rollout playbook.Collaborate as part of cross-functional platform teams: partner closely with core product and engineering counterparts, often as a single virtual team, to align on architecture and get to production together.Drive adoption outcomes: measure usage, identify blockers and failure modes, and prioritize the next platform increments that unlock repeatable value.You might thrive in this role if youBring 5+ years of software engineering or ML engineering experience with a track record of shipping 0→1 capabilities that other engineers or customers depend on. Experience in high-ambiguity, fast-iteration environments (startups or product-centric teams) is a plus.Have owned customer-adjacent technical work end-to-end, from scoping and hypothesis-setting through production adoption, and improved outcomes through structured iteration (instrumentation, evals, error analysis, and tightening success criteria over time).Have built or operated systems where reliability, security, and governance materially shaped design (permissions/RBAC, auditability, data access boundaries, rollout safety, observability, and incident-driven hardening).Communicate clearly across engineering, product, go-to-market, and executive audiences, simplifying complex ideas and translating technical tradeoffs into adoption impact, sequencing decisions, and measurable outcomes. You can credibly “pitch” a platform bet in a customer conversation.Default to systems thinking: you turn ambiguous feedback, failures, and escalations into durable product requirements and reusable platform capabilities, not one-off fixes or bespoke delivery work.About OpenAIOpenAI is an AI research and deployment company dedicated to ensuring that general-purpose artificial intelligence benefits all of humanity.

Who We're Looking For: The One Thing That MattersYou are the last line of defence between our code and patient care.TORTUS runs in hospitals, GP surgeries, ambulances, and across dozens of clinical environments — on iPads, in Epic, Cerner, Surgery Connect, EMIS, and multiple browsers. You'll own quality end-to-end: building the automated test infrastructure, running AI output evaluations, managing releases, and ensuring nothing ships that could break in any of those places. You'll be managing AI coding agents, building simulation suites for clinical AI outputs, and pioneering what quality engineering looks like when development is AI-accelerated.We’re looking for a technically strong QA engineer who is obsessed with AI tooling. You'll be building and maintaining automated test suites, but you'll also be running multiple coding agent instances, designing Playwright harnesses at scale, and creating entirely new kinds of tests — like evaluating whether our AI-generated clinical notes are correct. You'll also need to be comfortable rolling up your sleeves for hands-on manual and exploratory testing — complex clinical workflows across multiple deployment surfaces demand human judgement, not just automation. If you're the kind of person who sees AI agents as force multipliers rather than novelties, we want to talk to you.What Else Would Be Great2–5 years of experience in QA engineering, software testing, or SDET rolesHands-on experience with automated testing frameworks (Playwright, Jest, Vitest, or similar)Genuine enthusiasm for AI-assisted development — you're already using Claude Code, Cursor, Codex, or similar tools to ship fasterFamiliarity with CI/CD pipelines and integrating quality gates into automated workflowsUnderstanding of requirements traceability and how to maintain requirement to test case mappingExperience writing test plans, protocols, and verification reportsComfort testing across multiple platforms and environments (web, mobile, iPad, embedded in third-party systems)Exposure to compliance standards (IEC 62304, ISO 13485, ISO 14971) or Quality Management Systems is a strong plus — but not requiredStrong written communication — you'll be producing documentation that goes into our regulatory technical fileWhat You'll DoAutomated Testing & InfrastructureOwn and expand the end-to-end test suite using Playwright, Jest, and Vitest — covering unit, integration, system, and E2E testingBuild automated test harnesses for all deployment surfaces: web app, iPad, Epic, Cerner, Surgery Connect, EMIS, and multiple browsersDesign test cases covering functional requirements, edge cases, and failure modesIntegrate tests into CI pipelines to gate every PR with passing testsUse AI coding agents to accelerate test creation and maintenanceAI Output Evaluation & SimulationBuild end-to-end simulation suites for our clinical AI pipeline: upload known audio, verify transcripts, clinical codes, and guidelines are correctCreate smoke tests for AI outputsCollaborate with the ML team on AI evaluations — both deterministic tests and non-deterministic model output evaluationsDetect quality regressions when prompts, models, or pipelines changeRelease Management & QA GatingOwn the QA process for versioned releasesRun regression and manual exploratory testing across all supported environments before promoting to productionManage the release checklist — ensure nothing ships without verification on all target platformsTraceability & ComplianceMaintain the requirements traceability matrix, linking software requirements to test cases and resultsEnsure verification coverage with documented evidence for our regulatory technical fileSupport ISO 13485 audits and Class IIa certification with testing evidenceAutomate compliance workflows where possibleDefect ManagementLog, triage, and track defects with clear severity classificationWork with developers to reproduce issues, verify fixes, and close the loopEnsure no high-severity defects ship without resolution and re-testingWhat Does Wild Success Look Like?After 12–18 months, you've transformed how TORTUS ships software. The automated test suite covers all major deployment surfaces, and developers trust it to catch issues before they reach staging. You've built a simulation suite that catches AI regressions before they reach clinicians — we know within minutes if a release has broken clinical coding or note generation. The traceability matrix is immaculate, and auditors breeze through our verification evidence. Releases are versioned, documented, and predictable. You've reduced manual regression time by 70%+ through automation and AI-assisted test generation. The engineering team sees you as the person who makes it safe to move fast.Where Does This Role Take You?This is a foundational role in a fast-growing, safety-critical AI company.
