Staff Software Engineer, AI Platform (US - Remote or Calgary)

Syndio is a pay governance and compensation intelligence platform that helps organizations make fair, compliant, and data-driven compensation decisions. The Staff Software Engineer will own major surfaces of Syndio's AI agent platform, including runtime systems, evaluation infrastructure, observability, reliability, and compliance, while partnering with product teams on integrations.

Responsibilities:

• Core runtime surfaces of syndi-api: the agent loop, tool execution and registry, memory, context management (Python, Postgres, Claude on Vertex, GCP)
• The eval system — offline gates and online detector/judge evals written onto production traces — and its growth as product teams adopt it
• Production operation: observability (Datadog LLM Obs), incident response, the reliability of an agent surface real customers use
• The platform's contribution seams: reviewing product teams' tool wrappers and evals, evolving the GET /tools registry and drift-detection contract
• Clarifying, designing, and implementing compliance and legal requirements for Syndi

Requirements:

• 5+ years building production backend systems
• deep comfort with Python, relational stores, and cloud infra (we're on GCP/Kubernetes)
• built LLM-powered systems in production — an agent loop, tool-calling integration, RAG, or eval infrastructure
• design for operability: legal compliance, tracing, evals, and kill switches are part of the feature, not afterthoughts
• own a technical domain with light supervision: propose direction in writing with clear API specs, take review, ship, and carry the pager for what you shipped
• strong written communication
• experience being the platform side of a platform/product relationship
• SSE/streaming systems
• compliance-adjacent engineering (data minimization, auditability)
• prior Staff scope
