About this role

Your mission

Join our team and build the intelligent systems at the core of Cosuno's platform.

Generative AI: Build and improve our LLM-powered systems that navigate the complex, often messy tendering workflow.

Ship end-to-end into the product: Own features from model/agent through API to the TypeScript front-end — backend service, API, and the integration into the web app.

Collaborate across teams: Work with Product, Engineering, and Data to translate business problems into shipped AI features.

Maintain production AI: Monitoring, alerting, and continuous improvement of everything we deploy.

Your profile

TypeScript, React, Node: Non-negotiable. You're comfortable shipping into our web app end-to-end — front-end, backend service, API.

Strong Python: You have 5+ years writing production-grade Python. You write clean, well-structured code.

End-to-end product delivery: You've shipped AI-powered features into a production web app and owned the integration from research code to real users.

LLM application depth: You have deep hands-on experience building and deploying LLM/agent systems — RAG, tool use, multi-step reasoning, evals.

Backend engineering skills: You design APIs, data pipelines, and services.

Product mindset: You're comfortable with ambiguity and can judge when something is good enough to ship.

Sharp problem solver: You look at a complex system, quickly identify what matters, and decide what to do
