Software Engineer

🚀 Software Engineer – Building at the forefront of AI Package: £60,000-£140,000 (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. 🧠 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 🛠 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 💜 📧 Alex@wearebloom.io
