Responsibilities
- Actively participate in all phases of the software development lifecycle, regularly contributing code and reviewing code contributed by agents and the rest of the team
- Design, build, test, implement, and maintain features, capabilities, and fixes, end-to-end (frontend, backend, and DevOps) within our agent-paired workflow
- Develop full software stack features, applying UX principles to the UI, along with backend development, DB design, and AI integration
- Stay current with the latest AI-powered software engineering technologies, evaluating them for the product and leveraging them wherever appropriate
- Review and elevate AI agent output, critically evaluate code, specs, and analysis; catch what automation misses; enforce quality gates
- Be a key contributor to the Java to Go migration, including shadow-mode validation, and contract testing between legacy and new services
- Collaborate with Product Management and Customer Success to identify and address customer requirements, issues, and requests
- Advise on the feasibility of technical requirements, schedule considerations, and potential risk for proposed new development work
- Participate in building out, updating, and refining the product vision, plan, and roadmap
- Leverage industry standards and best practices to regularly assess and address technical debt, particularly in consideration of cost-savings efforts and strategies
- Collaborate with the DevOps team to implement, refine, and maintain infrastructure stability and availability, as well as continuous integration and deployment pipelines
- Feed the structured knowledge base: distill decisions, designs, and trade-offs into agent-readable markdown so agents and teammates can reason about them
- Follow TDD practices, writing tests before code as a default, not an afterthought
- Mentor and learn from an experienced product development team
