• Own and evolve our AWS infrastructure using Terraform and Pulumi Cloud - treating infrastructure as a product that engineering teams depend on. • Design and maintain internal developer tooling and libraries that standardize how we build and ship - code generation, shared SDKs, data access patterns, and service scaffolding. • Create and maintain golden paths for common workflows (new service setup, background jobs, event streams, APIs) so teams can ship quickly with built-in security and observability (and consistent defaults across services). • Build and maintain CI/CD pipelines and per-PR ephemeral environments that make deploying feel easy and safe. • Drive reliability through SLOs, auto-scaling, incident response, and postmortems - and build systems that make the next incident less likely. • Create observability tooling and shared instrumentation libraries that give engineers real-time insight into their services. • Enforce security best practices across IAM, secrets management, encryption, audit logging, and DDoS protection. • Own the reliability and performance of our data platform (Aurora PostgreSQL) - provisioning, backups, failover, and tuning - and build tooling that makes safe usage the default. • Reduce toil through automation and self-service tooling so engineers can move fast without waiting on the platform. • Contribute to architecture decisions and documentation, and participate in on-call rotation (shared by the whole engineering team).

• Design and build developer-focused tools and services that improve the software development lifecycle. • Implement AI-driven capabilities across engineering workflows, including code assistance, documentation generation, test automation, and code review support. • Improve the developer experience by identifying friction points and streamlining workflows. • Promote best practices for developer tooling and local development environments. • Design, deploy, and maintain the core AI platform infrastructure for production grade AI agents. • Participate in design and architecture discussions and contribute technical guidance. • Collaborate closely with engineers and cross-functional partners to deliver reliable systems. • Mentor other engineers through code reviews and design feedback.
