Founding Software Engineer

This is our first hire. You won't just be an engineer, you'll be a founding member shaping the technical foundation of a company that will enable 5% of the world's population to create video content.

Building creative software is uniquely challenging: there's no fixed process users follow. Everyone wants to create something new, express their ideas differently. This means endless edge cases and the need for exceptionally robust software.

Activities

• Partner with the founders to deliver user-centric product solutions from concept to production
• Own end-to-end development of full-stack features with scalable architecture design
• Build and optimize agentic LLM systems incorporating tool-calling, multi-step reasoning, and MCP protocols
• Design comprehensive LLM evaluation frameworks with automated benchmarks, human-in-the-loop validation, and A/B testing
• Optimize LLM inference performance, cost efficiency, and latency across multiple model architectures
• Develop a high-performance motion graphics engine
• Drive architectural decisions that support scalable growth to millions of users

Tech Stack

Our technology choices evolve with our needs. Current core technologies include TypeScript, React.js, Next.js, PostgreSQL, GCP/AWS, and our proprietary motion graphics engine. We prioritize learning velocity, end-to-end delivery, and adopt new languages or frameworks when they best serve our users and product goals.

Requirements

• You're a full-stack builder. You love shipping end-to-end features with modern tools like TypeScript, React, Next.js, and PostgreSQL.
• You think in systems. You design scalable architectures that balance speed, performance, and cost — and you make decisions that move the product forward
• You're hungry. Not just ambitious, but obsessed with building something massive
• You're entrepreneurial. You've built things before and demand ownership
• You thrive in ambiguity. No roadmaps, no PMs, just problems to solve
• You have a growth mindset. We're small today, but building something huge. To grow the company, each of us needs to grow personally
• You work like an athlete. High performance, consistent improvement, whatever it takes to win
• You want to work in-person in Berlin (we help you relocate if needed)
• We hire for slope, not intercept. We don't care about credentials; we care about trajectory
