What you’ll do
We need a Senior Product Engineer who works backwards from the experience.
This is someone who starts with the user’s problem, not a spec, and owns everything between that conversation and the code that ships.
You shape what gets built and how, contributing to product direction with real technical and strategic impact.
Global brands like Unilever, Google, and P&G already use it to catch shifts before competitors do.
Our ambition: become the go‑to platform for all consumer insights – the infrastructure companies run on, not a service they call in occasionally.
Own the full stack, from the interface to the infrastructure.
Build the internal tools the team uses every day and can’t imagine working without.
For us the interface is mostly Slack and
React: the agents people talk to and the apps they click through, built in Type Script.
And you don’t stop there.
From API and MCP design to infrastructure on Vercel, AWS, Supabase, and Big Query, plus the agents that work across the stack, you own complete features end to end, including the AI‑powered ones built on LLM APIs, prompt engineering, and async pipelines.
Be the engineering voice in every team you serve.
You’re embedded in the teams you build for.
When a sales rep, a CS manager, or a recruiter has a need, an engineer hears it, interprets it, and solves it.
You hold weekly one‑on‑one meetings with the people who actually use your tools, form a clear point of view on what to build, translate their feedback into scoped decisions, and follow through.
AI‑First.
You reach for agentic solutions first, using AI to reason, build, review, and test at every stage.
Building our own internal stack instead of buying third‑party tools means recreating, for our own purposes, software others spent twenty years building, so staying on the bleeding edge of AI is how we close that gap fast.
And because these are internal apps, we can lean on AI far more aggressively than an external product could: we’re close to our users, feedback is immediate, and the upside of a new feature usually outweighs the cost of a bug we can fix fast.
The bias is toward speed and learning.
We’re looking for people who thrive on that edge and help us continuously improve our software factory.
- What you’ll bring
- 5+ years of experience building applications or tooling that automate human workflows
- Full‑stack experience across the board: API design, databases, async workflows and background jobs on the backend, and clean, user‑friendly UX on the frontend
- Being AI‑native.
An early adopter of AI tooling, like agentic coding and software factories, with hands‑on experience building AI‑centric products through prompt engineering, LLM APIs, etc
- Extensive client‑facing experience turning customer problems into solutions people actually adopt
- Proven track record of leading projects from concept to launch
- Excellent written and verbal communication skills in English with a keen eye for detail
- A collaborative mindset, able to work autonomously in a small, fast‑paced team
- Bonus
- Deep affinity with the sales, customer success, recruitment or operation domains
- Experience at a small, fast‑moving Saa S company
- Experience building production apps with Type Script and Node. js
Why join us?
- Help figure out what an AI‑native company looks like internally
- Work directly with frontier AI models and push what they can actually do
- Join a YC‑backed team that’s growing fast and gives you room to grow with it
- Join one of the fastest growing companies in tech (20 → 120 this year)
- Competitive salary and meaningful equity
- Offices in London, Antwerp, and New York
- We work best together, so we ask for 3 days a week in the office
- Regular socials: rooftop drinks, team dinners, run clubs, and more
- Twice‑yearly off‑sites to places worth travelling to. Past locations are Austria, Las Vegas, and Portugal
- Private health coverage
- Enhanced employer pension contribution
- Refer someone great and earn up to £5,000
