The Senior Software Engineer will lead technically significant initiatives across the stack, building React interfaces, Node.js services, and PostgreSQL-backed systems. They will collaborate closely with product and design to deliver production-ready solutions, solve complex architectural problems, and elevate the engineering bar through technical leadership and execution. This role operates in an AI-first engineering environment, utilizing tools like Cursor, Claude Code, and agentic workflows as core components of the development process.
Requirements
- Actively use AI coding tools (Copilot, Cursor, agentic workflows) and understand their potential as force multipliers.
- 7+ years of professional software engineering experience.
- Deep expertise in TypeScript, React, and Node.js/Express.
- Experience owning complex features end-to-end in production.
- Strong eye for building well-architected, responsive, and accessible React applications at scale.
- Fluency in modern React patterns (hooks, context, component composition).
- Hands-on experience designing resilient backend services in TypeScript and Node.js.
- Comfort working with AWS services like SQS, ECS, and S3, as well as workflow tools like Temporal.
- Experience contributing to CI/CD pipelines and delivering software that is stable, efficient, and measurable in production.
- Experience designing and operating distributed systems, understanding trade-offs (consistency models, caching strategies, event-driven patterns).
- Substantial experience with PostgreSQL (or similar relational databases), including writing and tuning complex queries, designing schemas, and reasoning about data integrity and performance.
- Ability to approach ambiguous problems by breaking them down, evaluating trade-offs, and finding better ways forward.
- Communicate with clarity and purpose, especially when navigating technical decisions with non-engineers.
- Thrive in environments where engineering and product work closely together.
- Treat code reviews, feedback loops, and shared ownership as essential for building great software.
