Join our HQ team and help build the services that power the core administrative and operational experiences across our ecosystem. This role is for a senior engineer who can own backend outcomes end-to-end across the services the HQ web application depends onâdesigning durable APIs, strengthening reliability, and enabling the next phase of platform modernization. Youâll help unify and strengthen the services behind HQâworking in a polyglot environment where Java is core and Go/TypeScript/Python support key capabilitiesâwhile improving how we deploy, scale, and operate on EKS with GitOps. As a Senior Engineer, youâll own critical backend services, APIs, and event-driven integrations that keep HQ experiences reliable and scalable. Youâll collaborate closely with frontend, product, data, and platform teams to drive performance, operational excellence, and clear technical patterns that other engineers and contractors can follow. The outcomes youâll deliver: -Service reliability and scale: Design and maintain backend systems that support high-impact HQ workflows with predictable performance and resilience. -API clarity and stability: Establish strong contracts, versioning strategies, and error standards that reduce ambiguity and improve integration quality. -Event-driven maturity: Strengthen our data fan-out and cross-domain integrations using Kafka and event-driven design patterns. -Operational excellence: Ensure services are observable, well-instrumented, and resilient with meaningful dashboards, alerts, and reliability practices. -Team and delivery leverage: Raise the engineering bar through reusable patterns, reviews, documentation, and effective contractor guidance. -Platform evolution: Help harden domain services and reduce unnecessary coupling to monolith surfaces without slowing product delivery.
