Software Engineer

About the role

Cognition is an applied AI lab building end-to-end software agents and the makers of Devin, the first AI software engineer. Software engineers at Cognition work on open problems in applied AI, building agents that reason across code, coordinate subagents, use tools reliably, and handle long-horizon tasks in ways real engineers can trust.

Engineers ship systems directly into Devin and Windsurf, products that millions of developers use to write, debug, and ship code. The work connects model research with product development and includes moving quickly without cutting corners.

Responsibilities

• Design and ship core agent infrastructure for Devin's long-horizon task execution, including tool use, context management, multi-step planning, subagent orchestration, and sandboxed code execution environments.
• Contribute to Windsurf's editor intelligence, agent-in-the-loop workflows, real-time code understanding, and developer experience.
• Work directly with researchers to translate new model capabilities into shipped features and provide feedback that shapes training priorities.
