Senior Full Stack Developer (m/f/d)

LinkedIn job post

• Title: Senior Full Stack Developer (m/f/d)
• Location: Taufkirchen (Munich), Hybrid. Full-time.

🚲 About us

HEPHA is one of Europe's fastest-growing e-bike brands, combining high tech and design. Our digital team is growing, and we're looking for someone who builds, tests and runs projects in one.

📍 The facts

• Taufkirchen, south of Munich, at our new office. Hybrid possible
• Full-time, permanent preferred. Long-term freelancers welcome
• Start: as soon as possible

🎯 Why it matters

Our bikes are computers on wheels: motor, display, battery, app and cloud, all talking to each other. Every release changes how thousands of riders feel their bike, and they keep it for a decade. What you build goes from a spec to a bike on the road, and you get to ride it.

🛠 What you will do

You work directly with our digital lead and R&D. Many digital projects run at once: motors, displays, apps, web tools. You take a share, matched to your strengths, and what you take you own end to end, from the spec to the release on the bike:

• Build web apps, tools and prototypes (TypeScript, Python, Next.js, FastAPI) on agentic platforms (Claude Code, Codex)
• Run projects with our partners in China: write the specs, follow through, decide with us what goes on our bikes
• Test new firmware and app releases on real bikes and write down what you find
• Keep the pipelines running: CI/CD, hosting, monitoring
• Read a CAN trace, script a test rig, try the tool nobody asked for

At the start, expect more project management, testing and exploring than finished platforms.

🧰 What you bring

• Senior-level full-stack development with production experience
• Project management in practice: several projects at once, clear specifications, follow-through
• Daily work on agentic platforms (Claude Code, Codex or similar)
• DevOps and testing basics: CI/CD, Docker, cloud hosting, automated tests
• Love for bikes, no fear of hardware: multimeter, crimped cables, CAN bus
• Clear communication across cultures and time zones
• Fluent English

➕ Bonus: Mandarin (a real plus) or German; C/C++ basics to read firmware and CAN messages; Flutter or BLE; EU product compliance.

Maybe you're a developer who loves to organise, or a technical project manager who never stopped coding. You won't tick every box, and that's fine.

🎁 What we offer

• A role with real influence on how we work: tools, methods, process
• Top agentic tools and real bikes to test on
• Flexible hours, a development budget and a friendly team with short decision paths
• Attractive discounts on our e-bikes, and first rides on our newest models

🤝 How we hire

A couple of conversations, a work sample on a real problem of ours that you do in your own time, and half a day with us in Taufkirchen. No trick questions, and we tell you where you stand after every step.
