Cosine at a glance

  • Cosine is an autonomous, on-premise coding agent post-trained on human reasoning data to deliver unmatched software-engineering accuracy, security, and speed for regulated enterprises
  • What makes us unique is our in-house ML research lab that post-trains LLMs (e.g. GPT-5, gpt-oss, Kimi) on proprietary software-engineering reasoning data to dramatically increase their coding accuracy. In 2024 this gave us a world-leading score of 72% on OpenAI's SWE-Lancer benchmark
  • Cosine is now the only available managed product that can be fully air-gapped and deployed on premises, exciting many bulge bracket but extremely risk sensitive and strict enterprises that have rejected all other solutions on the market. We've got our first pilots up and running with global investment banks and defence primes and are now looking to scale our GTM function

  • Partner co-marketing:
    Coordinate joint events with our partners
  • Enablement & measurement:
    Build event kits (slides, runbooks, demo scripts) and define metrics - e.g. sign‑ups, trials, PQLs, SAOs influenced
  • Want to
    work hard
    and push yourself
    in return for significant upside

You'll thrive here if you

  • Are
    intellectually curious
    , with a willingness to learn, adapt, and master the content

    collaboration
    , working cross-functionally with Product, Sales, and Partner teams
