Job Description
Founding Engineer AI Motion Design Platform
YC-backed Berlin Onsite 80k120k significant equity
The opportunity
Were partnered exclusively with a YC-backed startup in Berlin thats building the AI system behind professional motion graphics. Their product turns a simple text prompt into polished broadcast-quality animated videos the kind that used to require After Effects a week of work and a specialist motion designer.
Theyre already used by creators and video teams with hundreds of thousands of subscribers and growing fast. The product works today. The question now is: how good can they make it
Theyre looking for a founding engineer to own that answer.
The role
This is a founding engineering hire. Youd own and evolve the core agentic AI pipeline a multi-agent system (Director Designer Animator) that orchestrates LLMs rendering logic and design intelligence to produce studio-grade output from a single prompt.
Your job isnt to build features for a roadmap. Its to make the AI output so good that non-designers create videos theyre genuinely proud of.
Day to day that means working across the full stack but the centre of gravity is the AI pipeline and backend systems that power it. Youd diagnose quality issues design solutions and ship them to production with minimal hand-holding. This is a role for someone who forms their own view on what needs building and then goes and builds it.
What youd work on
- Enhancing and extending the agentic animation pipeline prompt interpretation layout decisions animation sequencing and output polish
- LLM engineering prompt design evaluation frameworks failure mode analysis and iteration loops
- Backend and infrastructure pipeline orchestration cloud architecture (AWS) and system reliability
- Frontend when needed React/TypeScript UI work to close the loop between AI output and user experience
What theyre looking for
- Youve shipped LLM-powered products in production. You understand prompting evals and where models break down.
- Strong backend and infrastructure depth youre comfortable with pipeline architecture cloud services and systems that need to be robust.
- You can operate under ambiguity. You dont wait for a spec; you figure out what matters and move.
- You care about the end user. You work backwards from does this output look good not is this technically elegant
- Youre relentless. You keep pulling at a problem until the result is right.
Bonus points
- Youve built agentic or multi-step AI workflows (tool use orchestration state management)
- Experience with web-based creative tools design video audio canvas/WebGL or real-time rendering
- Early-stage startup experience youre comfortable with shifting priorities and wearing multiple hats
