[Remote] Staff Software Engineer (Platform Architecture & Execution Model)
Note: The job is a remote job and is open to candidates in USA. Red Cell Partners is an incubation firm focused on building and investing in scalable technology-led companies in healthcare, cyber, and national security. The Staff Software Engineer will be responsible for the core execution model and platform architecture of Trase OS, ensuring system correctness, scalability, and extensibility while defining abstractions and APIs for connecting various workflows and tools.
Responsibilities
- 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
Skills
- 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
- Prior work on workflow engines (Temporal/Cadence/AWS Step Functions, Argo, Airflow) or serverless runtimes
- Experience with policy engines (OPA), secrets/KMS, or data-handling controls (PII/PHI)
- ML/LLM evaluation frameworks, tool/plugin architectures, or embedding model governance into execution
- Government or healthcare experience (HIPAA, audit readiness) and multi-tenant isolation
