Zusammenfassung

FRYTE Mobility GmbH, based in Munich, seeks an experienced Backend IC to own production systems, setting the quality bar and driving robust, scalable architecture.

You will design multi-domain APIs, build observability, and mentor the team, with a trajectory toward Staff Engineer and broader system ownership across backend, infra, and frontend as needed.

Qualifikationen

• : Owning production backend systems in Python (FastAPI) on SQL/Postgres, with deployment and redesign depth.
• : Strong system design instincts, thinking about boundaries and failure modes before coding.
• : Architectural depth in charging, fintech, scheduling, or similarly stateful, integration-heavy domains.
• : Ability to operate across backend, infra, and occasional frontend fixes.
• : Teaching reflex; comfortable sharing knowledge and guiding others.

Aufgaben

• Own the architecture and production-hardening of our backend as we scale.
• Design and version stable, multi-domain APIs (integrations, real-time data streams).
• Build the observability backbone: logging, tracing, metrics for reliable operations.
• Raise the bar across the codebase with patterns, ADRs, reviews.
• Mentor and unblock the team through code and conversation; lift the ceiling for others.
• Move fluidly into DevOps, SRE, or frontend when needed.

Jobbeschreibung

FRYTE is redefining how electric logistics connects with the energy grid.

From our base in Munich, we're building the intelligence layer that powers the transition from diesel to electric freight.

Our SaaS platform enables fleet operators, dispatchers, and charge point operators to plan, optimize, and monetize electric truck charging — aligning fleet efficiency with grid stability.

Our vision: replace big oil with smart electrons.

Our mission: get e-trucks on the road – faster, smarter, more efficiently.

Tasks

This is a deep technical role for someone who wants to go deep, not climb an org chart.

You'll be the technical anchor of our backend — the engineer who sets the quality bar, owns the hardest design decisions, and quietly makes the whole system more robust and scalable. The person the rest of the team brings their thorny problems to, and who's genuinely happy to dig in.

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

Requirements

• 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

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.
