About Us

We\’re building the UK\’s first
AI-powered jobs platform
β€” a verified, spam-free alternative to LinkedIn. Our MVP will give:

  • AI Talent (candidates):
    Verified
    AI Career Passports
    (AI-enhanced profiles, skills verification, job matches, interview prep).
  • AI-first Employers:
    Instant AI-curated shortlists
    (JD β†’ top 10 verified candidates in minutes).

We\’re starting with the
AI talent niche
β€” AI Engineers, ML Researchers, Data Scientists, Prompt Engineers, MLOps Engineers β€” and scaling into the wider professional graph.

This is just the beginning. Beneath the platform, we are also developing a
stealth infrastructure layer
that can evolve into the backbone of recruitment and professional identity globally.

  • Design and implement the
    AI-driven matching engine
    (JD parsing, CV parsing, embeddings, fit scores).
  • Build dashboards for candidates, employers, and admin.
  • Work hand-in-hand with the founder (18 years recruitment experience) to shape product direction.
  • Set the
    technical foundation
    for future scale (from MVP to platform to infra).

This is a
founding-level role with significant equity
. If successful, you\’ll grow into
CTO or Head of Engineering
.

    and the
    stealth infra layer
    .

    18 years of recruitment expertise

    first AI Jobs unicorn
    .

Why This Role Is Special

    Engineer #1, Co-Architect, and future CTO
    .
  • You\’ll ship an MVP that proves market traction in
    weeks, not years
