Senior JavaScript Full Stack Engineer

We are seeking a Senior JavaScript Full Stack Engineer to serve as the technical lead for a pod covering five products, anchored by the explorer platform — the most complex product in the portfolio with 10 repositories, 5 event stream consumers, and a triple-write fan-out pattern across three data stores. In this role, you will own sprint delivery, drive event stream reliability improvements, and manage the field notes platform sunset migration alongside active feature delivery on the explorer and live events products.

Responsibilities
Provide technical direction across five products sharing a TypeScript/Node.js stack
Lead event stream reliability improvements, including dead-letter queue implementation, retry patterns, and consumer failure handling on the explorer platform
Own the authentication stability fix affecting the explorer platform's DynamoDB-backed auth layer
Conduct code reviews and uphold engineering standards across the pod
Own sprint planning, backlog refinement, and delivery risk management for the Exploration Pod
Manage the field notes platform sunset migration in parallel with active feature delivery on other products
Track and report on pod-level delivery health to the Engagement Lead
Mentor pod engineers and support their technical growth, particularly on event-driven patterns and PostgreSQL data modeling
Collaborate with the Business Analyst to ensure stories are well-defined before sprint planning
Participate in cross-pod architecture discussions with the Solution Architect
Coach engineers on effective AI-assisted development, particularly for complex event-driven debugging and data consistency problem-solving
Apply AI-assisted incident diagnosis to analyze logs, trace consumer failures, and suggest remediation steps
Requirements
3+ years of experience as a full stack engineer with strong event-driven systems experience
Experience leading a team through high complexity without losing delivery momentum
