Backend Software Engineer // AI Music Video Platform

About the role

Own the systems that turn songs into videos: video generation pipelines, model orchestration, queue management, and the infrastructure that keeps it all running at scale. You'll design and build backend services in Python that orchestrate multiple AI providers and gracefully handle their quirks, failures, and pricing trade-offs.

What you'll do

• Own the systems that turn songs into videos: video generation pipelines, model orchestration, queue management, and the infrastructure that keeps it all running at scale.
• Design and build backend services in Python that orchestrate multiple AI providers (we work with fal, BytePlus, OpenRouter, AWS and others) and gracefully handle their quirks, failures, and pricing trade-offs.
• Improve reliability, latency, and cost across the generation stack. Every second shaved off a render and every cent saved per video compounds across millions of generations.
• Build the infrastructure for new product surfaces working closely with the founder and tech lead on architecture decisions.
• Instrument and monitor what you ship. You'll have real visibility into how your code performs in production and the autonomy to fix what's broken.
• Contribute to the AI/ML side of the stack: prompt engineering, model evaluation, fine-tuning pipelines, and experimenting with new models as they ship.

What you'll need

• You've shipped production Python backends that handled real load - async workloads, queues, retries, the unglamorous stuff that makes systems actually work.
• You're comfortable working with AI APIs and have opinions about how to wrangle them: cost, latency, failure modes, model selection.
• You think in systems. When something breaks, your instinct is to find the root cause, not patch the symptom.
• You have high agency. You see a bottleneck, you fix it. You don't wait for a ticket.
• You're genuinely excited about generative AI and where it's heading. You probably have a side project or two that proves it.
• You're based in Berlin and can join us in the office on at least four days a week.

Nice to have

• Experience with video/audio processing pipelines (ffmpeg, GStreamer, etc.), GPU orchestration, multi-provider AI infrastructure, or distributed systems at scale.

What they offer

• VSOPs and profit sharing
• Bi-weekly team lunches and regular team events
• Annual summer offsite
• Learning and development support
• Deutschlandticket and 5,000 EUR referral bonus
