About The Position

This is a senior systems role with real ownership. Recall Masters (RM) is a leading B2B technology company in the automotive space. We deliver data-driven recall services that help dealers and OEM partners reach customers faster, resolve recalls more effectively, and improve service outcomes. Our platform runs the operational engine behind that delivery. It must be fast, secure, resilient, and observable at scale. You will report directly to Chris Miller, CoFounder and Chief Architect. Chris is hands-on and deeply technical. You will work close to core architecture decisions, own meaningful areas end-to-end, and help set the technical bar across backend reliability, data performance, and secure engineering practices. What you will own The robustness, scalability, and security of backend services that power mission-critical workflows System performance for data-heavy applications, including query efficiency and pipeline throughput Clear, durable integration patterns across third-party systems and internal services Architecture evolution across monolith, microservices, and event-driven systems Operational excellence: observability, monitoring, incident response readiness, and safe deployments The problems you will tackle (the fun part) Designing authorization and security patterns that scale cleanly across services Reducing latency in data-heavy workflows (PostgreSQL and Redshift) while keeping correctness high Building resilient async/event-driven processing for high-volume operational workloads Creating integration patterns that survive real-world failure modes (retries, idempotency, backoff, dead-lettering) Improving CI/CD and release confidence, including automated testing strategy and deployment safeguards Turning cloud infrastructure into an advantage (cost, speed, reliability), not an afterthought What success looks like in your first 90 days Ship a substantial backend improvement that measurably improves speed, reliability, or security Improve one critical data workflow end-to-end (query performance, throughput, cost efficiency, or stability) Strengthen observability in a key service area (metrics, logging, tracing, and alerting) Deliver a hardened integration or event-driven workflow with strong failure handling and test coverage
