Job Description
Staff Software Engineer – Platform Architecture, Execution Model
Red Cell Partners
• 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; partner with Product, Security, and Customer teams to translate requirements into durable primitives • Make pragmatic choices on storage, queueing, and compute; create paved roads that accelerate all other teams • Define system boundaries and reduce cross-service coupling through clear architectural patterns • Drive platform-wide standards for correctness, reliability, and API design across teams • Balance short-term delivery with long-term architectural integrity, ensuring the platform evolves without accumulating systemic risk
Job Requirements
- 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
- Proven ability to influence technical direction across an organization and drive adoption of architectural standards
- Ability to incorporate advance LLM capabilities into system design and platform architecture decisions where appropriate.
Benefits
- Career track opportunity with potential for rapid advancement with strong performance as the firm grows
