TL;DR

Staff Software Engineer (Platform Architecture & Execution Model): Own the core execution model and platform architecture of Trase OS, an agentic operating system for regulated enterprise deployments, with an accent on correctness-under-failure, determinism, and scalable orchestration. Focus on designing durable abstractions and APIs that connect workflows, agents, tools, and product surfaces while embedding security, governance, and end-to-end observability.

Company

hirify.global incubates and invests in technology-led companies, including Trase Systems, which builds an end-to-end AI deployment and management platform for enterprise use.

What you will do

• Develop the core execution model (state machine, lifecycle, resource model, failure semantics) for Trase OS.
• Design platform APIs/SDKs connecting workflows, agents, tools, and product surfaces, including versioning and compatibility.
• Guarantee correctness via idempotency, deterministic replays, compensating actions, and data integrity.
• Engineer reliability at scale with concurrency controls, rate limits, backpressure, sharding/partitioning, and workload isolation.
• Build security and governance into the core using RBAC/ABAC, policy enforcement, and fine-grained audit & lineage.
• Deliver observability (distributed tracing, structured logs, metrics, evaluation hooks) and own quality through testing, SLOs, incident response, and postmortems.

Requirements

• 10+ years of experience building distributed/platform systems, including architecture definition across teams or domains.
• Experience building mission-critical runtimes or workflow/orchestration systems.
• Deep expertise in durable execution (state machines, event sourcing, saga/compensation, idempotency, exactly/at-least-once semantics).
• Proven track record with security & governance in production (auth, RBAC, audit, policy).
• Hands-on observability experience (Grafana or equivalent), including trace correlation across async boundaries.
• Strong systems design across storage, queues, schedulers, and evented architectures; performance tuning under load.

Nice to have

• 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 in execution.
• Government or healthcare experience (HIPAA, audit readiness) and multi-tenant isolation.

Culture & Benefits

• 100% employer-paid comprehensive health care (medical, dental, vision) for you and your family.
• Paid maternity and paternity leave for 14 weeks at employees’ normal pay.
• Unlimited PTO with management approval.
• Optional 401K, FSA, and equity incentives available.
• Opportunities for professional development and continued learning.
• Mental health benefits available through Tara Mind; cost-effective GLP-1 solutions available through Crux.

Hiring process

• Application review and evaluation through hirify.global’ hiring platforms.
• Assessment of experience and fit for platform architecture, reliability, security, and observability requirements.
