Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior Full Stack Software Engineer - **Company:** FRYTE Mobility GmbH - **Location:** München, Germany - **Experience:** Expert - **Salary:** €75,000.0 - €100,000.0 - **Contract:** Permanent contract - **Skills:** Geographic Information Systems, Application Programming Interfaces (APIs), Amazon Web Services, Software as a Service, DevOps, Github, Python (Programming Language), PostgreSQL, Microsoft OneNote, PostGIS, Site Reliability Engineering Practices, SQL Databases, TypeScript, Management of Software Versions, Data Logging, ReactJS, Backend, Fastapi, Real Time Data, Front End Software Development - **Published:** October 4, 2026 - **Apply:** https://www.careerjet.de/jobad/de946b73a92ee38e6dac499119214536ec ## About the Role * A track record of owning production backend systems in Python (FastAPI) on SQL/Postgres - not just building in them. Carrying something you designed through deployment, failure, and the redesign that followed. (That depth usually takes 5+ years to earn; the years themselves aren't the point.) * Strong backend and system design instincts - you reason about boundaries, failure modes, and versioning before you write the first line * Architectural depth, ideally in charging, fintech, scheduling, or similarly stateful, integration-heavy domains * A habit of operating across boundaries - backend, infra, the occasional frontend fix, sometimes code you had no business touching - because the problem never cared what your job description said * A teaching reflex: you have an answer to most things and you're happy to share it ## Description We're explicit about this: this is an IC role with a Staff Engineer trajectory. No management obligation, ever. Your influence comes through architecture, code, and mentorship - not headcount. If your idea of growth is becoming the person whose judgement defines how a system is built, this is for you. One note on the title, because it travels badly between companies: we don't measure seniority in years, or in features shipped inside one familiar framework. We measure it in scope of ownership - systems you were responsible for when they broke, designs you had to revisit once reality showed up, assumptions that scale quietly humbled. Most good engineers learn that lesson several times, usually the annoying way. We'd rather hire someone who already has. You'll work directly with the founders (former TUM researchers with deep energy + logistics expertise) on the integration layer that makes electric freight actually work: multiple domains, real production traffic. What You'll Do * Own the architecture and production-hardening of our backend as we scale from seed onward * Design and version stable, multi-domain APIs (multiple integrations, real-time data streams) * Build the observability backbone - logging, tracing, metrics - so we operate with confidence, not hope * Raise the bar across the codebase: patterns, ADRs, reviews, and the unglamorous work that keeps things maintainable * Mentor and unblock the team through code and conversation - lift everyone's ceiling * Move fluidly into DevOps, SRE, or frontend when that's what the problem needs Our Stack Backend: Python, FastAPI, Postgres, PostGIS Frontend: React, TypeScript Infra: AWS, Bonus: GitHub Actions, observability tooling (tracing/logging/metrics), SRE practices, and a track record of maintaining or contributing to OSS - because you find it fun. Most of all: we hire for trajectory and attitude. We're looking for the humble, curious expert who's a mentor and coach by instinct - not because it's in the job description. Benefits Impact that matters - every system you harden helps decarbonize logistics. Foundational ownership - you define the architecture an entire platform is built on, at exactly the stage where that work compounds. A real IC ladder - Senior * Staff, with the founders invested in your technical growth, not in turning you into a manager. Genuinely hard problems - geospatial data, real-time optimization, multi-party integration at production scale. Hybrid setup - deep-work flexibility + a central Munich office. Perks that support you - JobRad, gym membership, family-friendly policies, and no compromise on hardware. How We Work * Asynchronous-first - less talk, more output. Today our knowledge lives in Notion and scattered markdown files; bringing real structure to it is part of the work - and the kind of thing you'll have a hand in shaping. * ️ Autonomy & ownership - we trust you to make decisions, not wait for permission. * Deep work - long focus blocks, low meetings. * ️ Hands-on, no bureaucracy - if something can be improved, improve it. * ️ Human connection - good coffee, real conversations. FRYTE Mobility GmbH FRYTE is a Munich-based Tech startup, bridging the gap between emerging electric logistics and energy markets.
