About the role

Key responsibilities & impact

Build Across the Stack: Develop modern frontend applications using TypeScript and React. Design and implement backend services in Python and Go. Build clean, well-tested APIs that power complex engineering workflows. Contribute to system architecture with an eye toward scalability, reliability, and security.
Solve Real Customer Problems: Engage directly with product managers, designers, and occasionally customers to understand real-world workflows. Translate ambiguous user needs into thoughtful technical solutions. Iterate quickly, validate assumptions, and refine features based on feedback.
Improve Developer & AI Tooling: Build internal and customer-facing developer tools, SDKs, and workflow automation systems. Integrate AI capabilities (LLMs, retrieval systems, copilots) into product experiences. Help improve CI/CD, local development environments, and engineering productivity.
Operate in Mission-Critical Environments: Build systems that function reliably in secure, regulated, or air-gapped settings. Balance speed with correctness, performance, and long-term maintainability.
