LLM features that ship, with evals so they don't drift.
Hiring an AI engineer in London? Senior ML / LLM engineers run $300K+ here and the pipeline is shallow. We ship AI features instead — chat UI, RAG, agents, evals — on a flat-price engagement that goes live in 2–5 weeks.
Local senior, year 1
$309K all-in

Two paths for ai engineer work
Hire local in London, or engage us
Path A · Hire local
~$309K
Year-one outlay for one senior ai engineer
- 60–90 day search through recruiters / inbound
- Vesting equity, signing bonus, relocation if remote
- One person, full-time, no flexibility on capacity
- Probation period: 90 days of unknown output
- If it doesn't work out: severance, recruiting cycle restarts
Path B · Engage Start Matter
From $8,000
Quoted after a 30-minute call
- Senior engineer starts inside seven days
- No equity, no signing bonus, no recruiting fee
- Flexible capacity — scope up or down between phases
- First deploy in two weeks — output you can ship to users
- Hand off cleanly when you hire your full-time team
What we do
The work, concretely
What you'd hand to a salaried ai engineer — we own end to end on a flat-price engagement.
- Chat / agent UI with streaming, interrupt, retry, citations done right
- RAG: chunking, embeddings, hybrid search, reranking, citation-required prompts
- Multi-provider routing via Vercel AI Gateway — primary + fallback + cost rules
- Evals as a CI gate, not a vibe check — held-out test set, regression alerts
- Cost observability — token spend per route, model tiering, caching
