Jobbeschreibung

What this is about

We're building a new product in realtime voice and communication – greenfield, with a stack we deliberately picked ourselves. No legacy, no feature treadmill. Instead, the technically interesting problems: low latencies, clean memory and threading behaviour, cross‑platform native components that stay stable under load – on Windows, macOS, Linux and mobile.

If you enjoy going deep into runtime, engine and pipeline topics and want to help shape a system from the ground up, this is your playground.

Your focus

The core is C++ and systems experience. That's the rare, hard‑to‑replace part – and exactly what matters to us. How deep you are in the other topics is open.

• Build native components in C/C++ and embed them into larger applications
• Work on performance, multithreading and cross‑platform behaviour
• Read, extend and occasionally patch existing engine/runtime sources – wired up through FFI bridges
• Get involved in native media, audio or graphics pipelines, depending on interest and background
• Shape things rather than just ship tickets – in a small team with short paths

Beyond the core

Around the C++ core we work in Rust (FFI and platform code) and TypeScript/Deno on the backend, plus PostgreSQL/MySQL, Redis and CI/CD on Linux and Docker. Godot is part of the stack.

You don't have to bring all of that. We're looking for someone who comes from C++ and wants to grow into the rest piece by piece. That's how it works here anyway – nobody on the team showed up knowing the whole stack; we all learned parts of it on the job.

What you bring

Must

• Solid experience with modern C++ in real projects
• Understanding of memory management and multithreading – not from textbooks, but from your own code
• Willingness to dig into unfamiliar native codebases and make targeted changes
• Openness to pick up Rust and some backend (TypeScript/Deno)

Nice to have

• Game engines like Godot, Unreal or native Unity plugins
• Engine source code, your own patches or native extensions
• Productive-level Rust

What we offer

• High ownership, lots of room to shape things technically
• Real technical problems instead of feature pressure
• Small senior team, direct communication, no micromanagement
• Pick your setup: macOS, Linux or Windows
• Remote‑friendly, office in Hamburg, two in‑person meetups a year
• 25 years of stable ground – and still the appetite to build something new
