Job Description

 We're looking for expert React + TypeScript engineers (frontend or fullstack) who are excited to move fast, solve real user problems, and shape the future of work with AI.Our engineers don’t just write code they build the product. That’s why we call them Product Engineers. You’ll own features end-to-end, from talking to users to shipping code.

What we are offering:

  • £70k–£100k +private medical + equity
  • Office in Central London (Holborn)

What are we building?

An AI Executive Assistant for people drowning in emails, meetings, and admin.
Most of today’s knowledge work looks like inbox chaos and calendar juggling. We fix that. Our AI plugs into your email, Slack, and calendar drafting replies, scheduling meetings, taking actions from conversations, and keeping you organised. It’s like having a top-tier assistant in your inbox 24/7.

We’re not a SaaS company bolting on AI….we’re AI-native, using the best of fine-tuned models, tool use, and retrieval to solve real workflows.

How’s it going?

  • Launched March 2024
  • $8M revenue with thousands of paying users globally
  • Went through HF0 in San Francisco (think Y Combinator, but for AI)
  • All this with an initial team of 4 (we’re now 20) and zero paid marketing until November 2024

We’re growing fast and planning to hit $30M revenue by the end of 2025. There’s a huge opportunity here and we want you to help shape it. We’ve also recently closed our Series A which was hugely successful.

What we value:

We believe a small, focused team of exceptional people can outpace much larger teams if they’re given ownership, trust, and the right problems to solve. That’s why we only hire Product Engineers: people who want to own the full product lifecycle, not just implement tasks.

If you thrive on intensity, autonomy, and building things that users love, you’ll fit right in.

What we’re looking for:

  •     Exceptional knowledge and experience with React + TypeScript
  •     Comfortable across the stack, frontend, backend, SQL, infra
  •     You’ve worked at a startup (<100 people), been a founding engineer (or one of the first few) or been a technical founder yourself.
  •     Product thinker: you want to talk to users, look at usage data, and shape what we build.
  •     High urgency and energy - you get things done fast and with purpose
  •     Passionate about AI and the future of work 

Our tech stack:

  •     Frontend: React + TypeScript
  •     Backend: GCP (Cloud Functions, Firestore, PubSub, Cloud Storage)
  •     Data: BigQuery, Looker
  •     Infra: GitHub Actions, Sentry, Google Cloud Logging 

Hiring process (fast + friendly):

  •     Upload your CV (no cover letter needed)
  •     20- 30min intro call
  •     45-min live coding session
  •     45-min product case study
  •     Final team lunch
