cosuno - Senior AI Product Engineer

• 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 next. • Bias for action: When you're unsure something will work, your instinct is to find out with data rather than keep wondering. • HOW WE BUILD: OUR ENGINEERING CULTURE • We believe in a calm, collaborative, and productive engineering environment. We trust our engineers and give them the autonomy to do their best work. Our approach includes: • Agile & Fast-Paced: We practice trunk-based development with daily releases to get value into our users' hands quickly. • Quality by Default: We maintain a comprehensive Cypress E2E test suite and enforce strict typing, linting, and formatting rules to keep our codebase clean and maintainable. • DevOps Mindset: Our well-oiled CI/CD pipeline deploys to AWS via Kubernetes, with our entire infrastructure managed as code using Terraform. • Collaboration & Transparency: We value open discussion, constructive code reviews, and a culture where the best idea wins, regardless of who it comes from.
