Software Engineer
🚀 Software Engineer – Building at the forefront of AI
Package: ÂŁ60,000-ÂŁ140,000 (Depending on experience)
UK/London - | Early stage AI Startup | High Impact, High Curiosity Role
If you’re a curious engineer fresh out of university (or with 1–3 years of experience) and obsessed with AI, you will not find a more exciting position or business than this! We're hiring multiple positions and are open to a range of seniorities)
We’re partnering with an extremely well-funded, seed-stage AI company building something foundational: interactive, resettable digital environments where AI agents learn through experience, not just static datasets.
Think: instead of just training on text, AI learns by actively using software, from video editing tools to complex simulation platforms, inside high-fidelity digital sandboxes .
This role sits at the heart of that mission.
đź§ The Role:
You’ll design the actual training curriculum for AI systems.
That means:
- Turning real-world software usage into hundreds of structured problems for AI models to solve
- Writing prompts, defining expected behaviours, and building verifiers
- Using Python + LLM APIs + clever tooling to generate tasks at scale
- Experimenting constantly to improve how models learn
It’s hands-on, experimental, and highly technical. There’s rarely a single “right” answer -progress comes from trying things, iterating fast, and finding leverage .
If you like building scrappy prototypes, hacking together clever solutions, and seeing immediate results, you’ll thrive here.
🔍 What You’ll Be Doing
- Creating structured problem sets that train AI models on real software
- Building Python-based verification systems to evaluate AI behaviour
- Collaborating with domain experts to translate messy real-world workflows into structured learning tasks
- Designing tooling, scripts and agentic workflows that multiply output over time
- Running fast feedback loops and QA to ensure quality before delivery
đź› What we're Looking For
- 1+ years using Python to solve real problems
- Software engineering fundamentals
- Experience using LLM APIs or working with agent-style systems
- A hacker mindset - pragmatic, experimental, not obsessed with over-engineering
- Comfort with shipping fast, learning fast, iterating fast
- Genuine intellectual curiosity - you enjoy diving into new technical domains
This would suit someone:
- Fresh out of university with strong internship experience
- Or 1–2 years into their career and wanting serious responsibility
- Who wants exposure to frontier AI work without 1,000 layers of corporate process
🌍 Why This Is Special
- You’ll work on one of the most technically interesting problems in AI right now
- Small team, massive impact — your work ships directly to leading AI labs
- Seed-stage but well-funded and backed by top-tier founders and investors
- High-trust, low-bureaucracy culture
- Competitive salary + per-deliverable bonuses
This isn’t a “maintenance engineering” role. It’s experimental, foundational, and high-agency.
If you’re the kind of person who:
- Builds side projects for fun
- Breaks tools to understand how they work
- Gets excited about LLMs and agent systems
- Wants to be early in something that could matter
Please apply or DM me for details - they’re still in stealth, so we’ll share more privately 💜
