Staff Software Engineer (Platform Architecture & Execution Model)

Skills

About the Role

You'll own the core execution model and platform architecture of Trase OS, the shared agentic operating system that powers all Trase deployments in regulated environments. You'll define the abstractions and APIs that connect workflows, agents, tools, and product surfaces, ensuring the correctness, scalability, and extensibility of the system. This is a company-critical role where you're responsible for how the system behaves under real-world conditions including failure, scale, and security constraints. You'll set the technical direction for the platform and act as a force multiplier across all engineering teams, designing systems where failure is the norm rather than the exception, and where correctness must be preserved across retries, restarts, and partial execution. You'll balance clean abstractions with real-world constraints like performance, security, and multi-tenant environments, building foundational primitives used across all products and teams while keeping the system understandable and auditable as complexity and scale increase.

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 such as state machines, event sourcing, saga/compensation, idempotency, and exactly/at-least-once semantics
• Proven track record with security and governance in production systems including auth, RBAC, audit, and policy
• Hands-on experience with observability tools such as Grafana or equivalent, including trace correlation across async boundaries
• Strong systems design across storage, queues, schedulers, and evented architectures with 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 with a bias toward correctness, clarity, and documentation
• Proven ability to influence technical direction across an organization and drive adoption of architectural standards
• Ability to incorporate advanced LLM capabilities into system design and platform architecture decisions

Responsibilities

• Develop the core execution model including state machine, lifecycle, resource model, and failure semantics
• Design platform APIs and SDKs connecting workflows, agents, tools, and product surfaces
• Drive versioning and compatibility across platform interfaces
• 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 including RBAC/ABAC, policy enforcement, and fine-grained audit and lineage
• Deliver observability through distributed tracing, structured logs, metrics, and evaluation hooks
• Build an explainable trail of agent actions
• Own quality through design reviews, test strategy, performance baselines, SLOs, incident response, and postmortems
• Mentor and 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
