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

Note: The job is a remote job and is open to candidates in USA. Syndio is hiring a Staff Software Engineer to take ownership of major surfaces of its production AI platform and grow into a technical owner of the platform. The role involves designing, shipping, and operating agent runtime and evaluation systems, supporting product-team integrations, and ensuring reliability and compliance.

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

Skills

• 5+ years building production backend systems; deep comfort with Python, relational stores, and cloud infra (we're on GCP/Kubernetes)
• You've built LLM-powered systems in production — an agent loop, tool-calling integration, RAG, or eval infrastructure — and have opinions from the scar tissue
• You design for operability: legal compliance, tracing, evals, and kill switches are part of the feature, not afterthoughts
• You can 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 — our operating model runs on design docs and PR review across team boundaries
• Experience being the platform side of a platform/product relationship
• SSE/streaming systems
• Compliance-adjacent engineering (data minimization, auditability)
• Prior Staff scope

Benefits

• Syndio Equity. So you can share in Syndio’s success
• Flexible Vacation Policy (up to 20 days PTO in Canada)
• Paid sick & safe time
• Compassion leave
• Voting leave
• Medical, Dental, Vision. Syndio pays 90% of employee premiums, and 50% for dependents.
• Life Insurance & Disability. Syndio covers the full premium.
• Remote-first in US + Alberta; in Calgary, non-mandatory office available
