Job description

Working with product managers, architects, and engineers across COSMIC, you will take problems from design through production, make sound technical decisions, use production signals to improve the system, and help other engineers succeed through technical leadership. Own the design, implementation, rollout, and operation of significant COSMIC App Platform features and services from requirements through production. Build distributed platform and orchestration components that enable AI agents to coordinate and execute deployment, capacity, resiliency, recovery, and optimization workflows at fleet scale. Design safety boundaries including sandbox isolation, scoped identity and access, policy and approval checks, auditable execution, rollback, blast-radius containment, and human oversight. Drive production readiness through health-gated releases, observability, alerts, runbooks, on-call support, and incident follow-up. Build evaluation, experimentation, feedback, and learning loops with measurable system-quality and operational outcomes. Translate customer and operational needs into sound designs, testable software, and clear success criteria while resolving cross-team dependencies and delivering end-to-end scenarios. Investigate complex production issues using telemetry and data, identify root causes, and deliver durable fixes that improve reliability and supportability. Lead feature-level technical reviews, contribute to architecture and roadmap decisions, mentor engineers through design and code reviews, and improve reusable engineering patterns and tooling. Bachelor's Degree in Computer Science or related technical field AND 4+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python or Rust. These requirements include but are not limited to the following specialized security screenings: Master's Degree in Computer Science or related technical field AND 6+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR Bachelor's Degree in Computer Science or related technical field AND 8+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience. Experience designing, building, and operating distributed systems, cloud services, or Kubernetes-based infrastructure. Experience owning complex features or services from design through production, including reliability, instrumentation, and supportability. Experience with production AI or agent systems, workflow orchestration, control planes, or intelligent automation. Experience implementing safety, policy, identity, authorization, observability, evaluation, or approval mechanisms for automated systems. Solid coding, debugging, testing, and systems design skills, with attention to maintainability and operational quality. Experience using telemetry, experiments, and customer feedback to improve product and system outcomes.
