Senior/Staff Software Engineer (Platform and Execution Model)
Redcellpartners · Seattle, WA (Preferred) or McLean, VA or Remote (USA)
About this role
## About Us Red Cell Partners is an incubation firm building and investing in rapidly scalable technology-led companies bringing revolutionary advancements to market across healthcare, cyber, and national security. ## About Trase Trase Systems is AI, Uncomplicated. Trase empowers enterprise leaders to harness the full potential of AI without the associated complexity and risks—providing an end-to-end solution for deploying, managing, and optimizing AI in the enterprise. Trase is at the forefront of AI Agent innovation, and is leveraging cutting-edge technologies to develop mission-critical agentic applications in complex industries such as Healthcare, Oil & Gas, and National Security. ## About The Role As a **Senior or Staff Software Engineer**, you’ll build and own critical parts of **Trase OS**, the shared platform that powers Trase deployments in regulated environments. You’ll work on distributed systems and platform primitives connecting **workflows, agents, tools, and product surfaces**, with a particular focus on **reliability, scalability, and correctness**. This is a hands-on engineering role for someone comfortable going deep on distributed systems while helping other engineers make sound architectural decisions. Staff-level candidates are expected to lead architecture across teams, establish engineering standards, and mentor other engineers. ## Why This Role is Needed Trase OS is an orchestration-heavy system coordinating long-lived workflows, agents, and tools across multiple services and environments. As the platform evolves, the primary risks shift from implementation to **system design quality**—including abstraction quality, failure reasoning, reusable primitives, and scaling leverage. This role exists to: - Design and implement clean, durable abstractions for the platform execution model - Ensure correctness and determinism in workflow execution - Translate evolving product requirements into coherent platform architecture - Enable teams to build on Trase OS without introducing systemic complexity ## What Makes This Role Challenging - You’re designing systems where failure is the norm—correctness must be preserved across retries, restarts, and partial execution - You must balance clean abstractions with real-world constraints (performance, security, multi-tenant environments) - Your decisions become foundational primitives used across all products and teams - The system must remain understandable and auditable as complexity and scale increase ## Responsibilities - Design, build, and own critical components of the core execution model (state machine, lifecycle, resource model, 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: concurrency controls, rate limits, backpressure, sharding/partitioning, and workload isolation - Build security and governance into the core: RBAC/ABAC, policy enforcement, fine-grained audit and 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
