Job description

We’re removing one of the last great barriers to progress in the physical world. While software moves fast, industries like aerospace, healthcare, and energy are still slowed by outdated, manual systems.

Rapidly growing in stealth with 6 figure revenue in 3 months

Raised a 14x oversubscribed $4.5m seed round from Tier 1 VCs - Coinbase, Reddit, Klarna, Spotify

This is a once-in-a-generation shot to define how humanity brings new ideas into the real world. We’re going to take the opportunity by moving fast, working with intensity, and executing without compromise.

Who we are looking for

Problem Solver - You love solving hard problems (proven history of doing so).

Proven Builder - 2+ years as an engineer with a track record of fast, production-grade code shipping.

Applied LLMs - Experience deploying multimodal foundation model-based products. Deep knowledge of LLM research, agents, tools, and function calling.

Deploying LLMs - Experience with LangChain, indexing, RAG, semantic search, and fine-tuning (SFT/RL) of LLMs/agents.

Your First Month at Seamflow

Ship from Day 1 - You deploy to production day 1 and take ownership for code.

Own it - You create specs, figure things out, and build features end-to-end.

Solve Every Problem - From scaling infra to hiring the next teammate to jumping on customer calls, you do what needs doing.

We Offer

Pace & Purpose: We work 6 days a week, together in London (in-person, we sponsor visas), because we don’t want to look back and think we could’ve pushed harder.

Top-of-Market Reward: Base Salary (minimum £100k) + meaningful equity and the chance to do career-defining work.

No Friction: We cover relocation, visas, team meals, and whatever tools or resources you need to move fast.

A Tight-Knit Team: We work hard because we care, but we also laugh a lot, eat together, and back each other completely. Everyone here is here because they want to build something meaningful, with people they genuinely like.
