SUMMARY As a Senior/Staff Infrastructure Engineer, you will own the reliability, availability, and operability of our core Python web services running at scale on AWS. You will be responsible for designing, maintaining, and improving the production infrastructure that keeps Hedra online: Kubernetes for orchestration, AWS as the core cloud platform, and Postgres on RDS as a key managed data service. Your work will focus on building a highly available runtime environment for our services, ensuring we can ship quickly while staying resilient through incidents, traffic spikes, and growth. You will design robust deployment patterns on Kubernetes, optimize our use of AWS (networking, load balancing, scaling, resilience), and put in place the observability and alerting we’re currently missing — from system-level metrics to product health signals. You’ll also partner with product engineers to make Python a great place to build: smoothing out CI/CD, runtime configuration, and production debugging. This is a hands-on infrastructure role, not a product feature role. You will work closely with engineering leadership and product teams, but your primary mandate is to keep our services healthy, observable, and ready to scale. We're looking for a full-time hire in our San Francisco office.
