What You’ll Do:

- Own large features end to end, from design through deployment, release, and monitoring
- Deliver scalable, event-driven, AI-native applications that elevate the customer experience
- Collaborate with platform teams to enhance overall system architecture
- Own the design, implementation, quality and safety of AI/agentic features in production systems
- Mentor other engineers across levels through code review, pairing, design collaboration and coaching
- Drive adoption of tooling and practices, including AI developer tooling, and codify the habits that make them effective
- Advocate for the proactive investments — refactors, observability, upgrades, technology adoption – that enable continuous improvement
- Communicate fluently across product, design, solutions, and ops to align outcomes with business goals
- 8+ years of full-stack experience
- Proven track record building distributed, cloud-native applications, with hands-on serverless experience
- Demonstrated experience shipping AI/LLM features to production
- Strong instincts for API design and backwards compatibility — especially where events drive money movement or fulfillment
- A track record of owning large, ambiguous, cross-system initiatives end to end
- Proven ability to influence beyond your team — aligning groups, distilling complex ideas for leadership, and pushing back with data
- A pattern of mentoring across levels and driving team-wide improvements that outlast any single project
- Strong data modeling and context engineering skills that ensure application quality and sound agentic decisioning
- Fluency with advanced AI developer tooling, a track record of using it to ship more, and a habit of bringing teammates along
- Exceptional communication across product, business stakeholders, designers, support, and engineers
- Expert in TypeScript, Node.js, and React
