We are seeking a Senior Exploration Full-Stack Engineer to lead feature delivery, technical hardening, and architectural improvements across the explorer platform and live events product within the Exploration Pod.
In this role, you will drive API security strategy, own dependency vulnerability remediation at scale, and shape feature delivery across two products that share a common Next.js + NestJS + CMS architecture. The ideal candidate is a seasoned TypeScript engineer who can context-switch seamlessly between products, mentor peers, and treat security and reliability as first-class engineering concerns alongside feature delivery.

Design and implement rate limiting strategy on the live events API to mitigate identified DDoS risk
-
Define and roll out HMAC authentication patterns to harden webhook endpoints across both products
-
Own the triage and remediation strategy for the 1000+ dependency vulnerabilities identified in the live events product
-
Establish dead-letter queue and retry patterns as standards for Lambda workers and async processors
-
Set testing standards and mentor others on unit, integration, and E2E test practices to meet and raise coverage gate targets
-
Lead code reviews, define engineering standards, and champion best practices within the pod
