Key responsibilities & impact

Design, build, and own critical components of the core execution model, including state machine, lifecycle, resource model, and failure semantics
Build reliable distributed systems that behave predictably across retries, restarts, partial failures, and concurrent execution
Develop platform APIs/SDKs connecting workflows, agents, tools, and product surfaces; drive versioning and compatibility
Guarantee correctness via idempotency, deterministic replays, compensating actions, and data integrity
Engineer reliability at scale through concurrency controls, rate limits, backpressure, sharding/partitioning, and workload isolation
Build security and governance into the core through RBAC/ABAC, policy enforcement, and fine-grained audit and lineage
Deliver observability through distributed tracing, structured logs, metrics, evaluation hooks, and an explainable trail of agent actions
Own quality through design reviews, test strategy, performance baselines, SLOs, incident response, and postmortems
Mentor engineers, contribute to design reviews, and establish strong engineering patterns across the platform
Work on Trase OS, the shared platform powering AI deployments in regulated environments

What you’ll need

8+ years of experience building distributed/platform systems, including significant experience defining architecture across teams or domains
4+ years owning mission-critical runtimes or workflow/orchestration systems
Deep expertise with durable execution, including state machines, event sourcing, saga/compensation, idempotency, and exactly/at-least-once semantics
Proven track record with security & governance in production systems, including auth, RBAC, audit, and policy
Hands-on with observability, including Grafana or equivalent and trace correlation across async boundaries
Strong systems design across storage, queues, schedulers, and evented architectures; performance tuning under load
Excellence in a modern language such as Go, Rust, Java, or TypeScript and cloud-native stacks including containers, CI/CD, and IaC
Comfortable operating in regulated or high-assurance environments; bias toward correctness, clarity, and documentation
Strong technical judgment and ability to influence design decisions within a team and across closely related engineering areas
Ability to incorporate advanced LLM capabilities into system design and platform architecture decisions where appropriate
