About the role
- Leading design and delivery of commerce features that drive measurable business impact for both self‑serve and enterprise customers, owning outcomes end‑to‑end.
- Guiding platform scaling initiatives, improving reliability and performance in user‑critical flows, and raising quality bars through robust instrumentation.
- Partnering with Product and Design to clarify requirements, define MVPs, and instrument experiments that validate value quickly.
- Attending agile ceremonies and helping the team make predictable, incremental progress with clear priorities and limited WIP.
- Collaborating across squads to improve engineering practices, evolve monorepo tooling, define service boundaries, and reduce operational toil.
- Reviewing and authoring implementation plans and pull requests with a focus on simplicity, maintainability, observability, and incremental delivery.
- Mentoring and coaching engineers through pairing, technical design reviews, thoughtful feedback, and structured growth guidance.
- Using AI assistants thoughtfully to scaffold code, generate tests, draft documentation, analyze logs, and accelerate experiments. Choosing when not to use AI based on risk, privacy, and correctness considerations.
Requirements
- 7+ years of professional software development experience in a SaaS or technology‑driven environment, with a track record of owning systems and features end‑to‑end.
- Strong proficiency in React and TypeScript for modern front‑end web development, supporting end‑to‑end feature delivery.
- Strong proficiency in backend engineering with Node.js and/or Ruby on Rails including building and maintaining scalable services and APIs that are observable, reliable, and secure.
- Experience with PostgreSQL, including schema design, query optimization, and data modeling for transactional systems.
- Experience designing and consuming GraphQL APIs in production environments.
- Background in mixed stack environments, such as Node.js services interfacing with a Ruby on Rails monolithic API, or similar mixed stack environments.
- Hands-on experience with Service Oriented Architecture (SOA), microservices, and involvement in monolith‑to‑services modernization or large‑scale refactoring initiatives.
- Proven ability to lead technical discovery and design, decompose complex problems, and deliver small, incremental, high‑quality releases.
- Demonstrated mentorship and coaching of other engineers, including elevating standards through design reviews, documentation, and reusable patterns.
- Strong analytical and problem‑solving skills, with the ability to dissect complex systems, identify root causes, and deliver scalable, maintainable solutions.
- A commitment to writing clean, reliable, and maintainable code, with an emphasis on readability, simplicity, and performance.
- Adaptability to new technologies, evolving architectural patterns, and changing organizational priorities.
- Availability for participation in an on‑call rotation, ensuring timely and effective responses to critical production issues outside of regular working hours.
- Comfort and proficiency using AI tools in engineering workflows to increase velocity and quality, including effective prompt craft, critical review of outputs, and responsible data handling in line with privacy and security expectations.
