About the role

Key responsibilities & impact

Develop the core execution model (state machine, lifecycle, resource model, failure semantics)
Design platform APIs/SDKs connecting workflows, agents, tools, and product surfaces
drive versioning & compatibility
Guarantee correctness via idempotency, deterministic replays, compensating actions, and data integrity
Engineer reliability at scale: concurrency controls, rate limits, backpressure, sharding/partitioning, and workload isolation
Build security & governance into the core: RBAC/ABAC, policy enforcement, fine-grained audit & lineage
Deliver observability: distributed tracing, structured logs, metrics, and evaluation hooks
build an “explainable trail” of agent actions
Own quality: design reviews, test strategy (unit, property, chaos), performance baselines, SLOs, incident response, and postmortems
Mentor & unblock senior engineers

Requirements

What you’ll need

10+ years of experience building distributed/platform systems, including significant experience defining architecture across teams or domains
Experience building mission-critical runtimes or workflow/orchestration systems
Deep expertise with durable execution (e.g., state machines, event sourcing, saga/compensation, idempotency, exactly/at-least-once semantics)
Proven track record with security & governance in production systems (auth, RBAC, audit, policy)
Hands-on with observability (Grafana or equivalent), including trace correlation across async boundaries
Strong systems design across storage, queues, schedulers, and evented architectures
performance tuning under load
Excellence in a modern language (e.g., Go, Rust, Java, or TypeScript) and cloud-native stacks (containers, CI/CD, IaC)
Comfortable operating in regulated or high-assurance environments
bias toward correctness, clarity, and documentation
