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 state-of-the-art 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

The role

You’ll build Cosine’s partner engine from zero to one: you’ll sign and activate strategic partners (SIs/GSIs, ISVs, cloud marketplaces, boutiques, and investor networks), create repeatable co‑sell and referral motions, and turn partner relationships into qualified pipeline and revenue.

Your responsibilities:

• Source & activate partners: Identify, recruit, and onboard high‑leverage partners; own evaluations, mutual value propositions, and first joint wins
• Drive revenue with co‑sell: Build account maps and joint plays with Sales; run deal registration, pipeline reviews
• Programme & enablement: Stand up a lightweight Partner Programme - tiers, T&Cs, deal‑reg rules, MDF guidelines, and enablement kits (one‑pagers, demo story, security FAQ)
