About the Role
You will own product features from database design through the final interface and production support. You will build React and TypeScript front ends, develop Python or Node.js services, design durable APIs and relational schemas, and create AI-native capabilities involving LLM orchestration, retrieval, agents, and structured outputs. You will automate engineering and security workflows, apply secure coding practices, review code, and document architectural decisions. You will also deploy and operate containerized services, cloud infrastructure, CI/CD pipelines, and monitoring while translating specialist security knowledge into accessible software.
