Job Title: AI Engineer

Salary: $100K-$400K + Equity

Company Description: Solve Intelligence - YC-backed AI startup transforming the patent industry

Job Description: Join an elite team of Cambridge, Oxford, and UCL PhDs building the future of AI-powered patent technology. As an early engineer, you will push the boundaries of LLM algorithms and agents for a platform seeing 20-30% month-over-month growth. You'll solve high-intensity technical challenges while shipping production systems to 400+ global IP teams.

Location: London, UK

Why this role is remarkable:

  • Join a rocketship with 8-figure ARR and $55M in funding from premier investors including Y Combinator, 20VC, and the founders of Stripe and Perplexity.
  • Work in an ultra-high talent density environment alongside former researchers from DeepMind and the Gatsby Unit who value raw intelligence over corporate tenure.
  • Realize massive upside potential with a compensation package including significant equity in a profitable company disrupting a $200B+ global industry.

What you will do:

  • Design and implement state-of-the-art LLM-powered systems, agents, and evaluation pipelines to automate complex patent drafting and litigation workflows.
  • Architect and scale robust backend infrastructure using Python and PostgreSQL to support a rapidly expanding global user base and massive document volumes.
  • Collaborate directly with the founding team to make foundational technical decisions and ship high-impact features to production in rapid cycles.

The ideal candidate:

  • Demonstrates exceptional raw intelligence through top-tier academic performance (Olympiad medalist or first-class degree from Oxford, Cambridge, Imperial, or MIT).
  • Possesses deep technical expertise in AI/ML, specifically with LLMs, and a track record of building production-grade systems or publishing at venues like NeurIPS.
  • Exhibits a high-intensity builder mentality with the drive to thrive in an in-person London startup environment where shipping fast is the priority.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
