Full-Stack Engineer

dehaze AI identifies chronic disease risks on already existing health data. Our customers, fully integrated insurers, save ~10% of their yearly health budget. Your job is to make sure what we build is what customers actually need; validated, defensible, and tied to business outcomes. Build products from prototype to final Product, and establish a testing culture and infrastructure the whole team builds on. Tasks Product Development Develop and iterate on the core applications (frontend + backend), moving from prototype toward MVP and beyond Implement authentication, authorization, and role-based access control Build internal tooling and dashboards for other teams Set up CI/CD pipelines, containerization, and basic infrastructure-as-code Collaborate on security architecture: audit trails, session management, and secure coding practices QA – Application Testing & Quality Infrastructure Set up the foundational test stack: unit testing, integration testing, and end-to-end testing frameworks Establish CI/CD quality gates; no code merges without passing tests, linting, and security scans Write and maintain automated test suites for critical user flows and API endpoints Implement basic load/stress testing before any clinical or pilot deployment Champion code review standards and define a meaningful QA checklist the whole team follows Set up error monitoring and alerting (Sentry, Datadog, or similar) so bugs surface fast Document testing standards and onboard existing engineers into the QA workflow Requirements Must Haves 3–5+ years of full-stack development experience Strong backend skills (TypeScript preferred) Frontend competency (Angular, React, or similar) Proven experience setting up test infrastructure from scratch (Vitest, Jest, Cypress, Playwright, or similar) CI/CD pipeline design and maintenance Security mindset: OWASP Top 10, secure coding, encryption basics Nice-To-Haves Prior experience in a regulated or healthcare industry HIPAA, SOC 2, and medical device compliance at the application layer Infrastructure-as-code (Terraform, Pulumi) Startup experience and comfort with ambiguity Benefits Serial founder team: Work directly alongside serial healthtech entrepreneurs and one of Europe’s leading professors in medical AI. The founding team has built and exited 3 health startups and operated in hyperscaler environments. Technological frontier: Our proprietary AI builds on a novel architecture unlocking already existing health data. You’ll be at the forefront of technology that fundamentally changes how chronic diseases are identified. Intense speed and impact: We measure quality of life improvements and cost savings. We plan to 10x our ARR in the first year. Global scope, real ownership: Technology and science are built in Germany. We entered the market in Brazil and are expanding to the US and EU. Your decisions will impact how we scale across markets, regulatory environments, and cultures. Growth trajectory: This role is designed to grow with the company that is scaling internationally. Competitive salary plus equity participation (VSOP) because we want you to build this with us, not just work for us. No cover letter templates. No generic applications. If you can’t articulate why this specific role at this specific company in 5 sentences, we’re probably not the right fit. ABOUT DEHAZE dehaze is building proprietary AI infrastructure to identify risks of chronic diseases earlier and more precisely on already existing health data.
