Cosine at a glance

======================


At Cosine, we're building agentic AI systems designed to take real action in the world.


We're not a chatbot or a thin wrapper around existing models. Our systems are built to run in on-premises, closed-loop environments, including fully air-gapped deployments, where reliability and control matter.


In 2024, Cosine achieved a 72% score on OpenAI's SWE-Lancer benchmark, placing us among the strongest real-world software-engineering AI systems evaluated.


YC-backed and well-funded, Cosine was founded by experienced operators focused on building dependable, production-grade AI.

This role is based in our Hoxton office, five days a week, because close collaboration, fast feedback, and shared context matter for the problems we're solving.
