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

Syndio • Calgary, AB

16h • $205,000 - $225,000 • Remote

About The Position

Syndio is seeking a Senior Software Engineer to join their AI Platform team. This role will focus on Syndio's AI platform, 'Syndi', which is an AI agent experience built on syndi-api. The platform handles orchestration, tool calling, memory, RAG, evals, and observability. The engineer will take ownership of major runtime surfaces and grow into a technical owner of the platform. This is a high-autonomy role on a small team where the engineer will design, ship, and operate systems end-to-end, working directly with product-team owners.

Requirements

• 5+ years building production backend systems
• Deep comfort with Python, relational stores, and cloud infra (GCP/Kubernetes)
• Experience building LLM-powered systems in production (agent loop, tool-calling integration, RAG, or eval infrastructure)
• Designs for operability: legal compliance, tracing, evals, and kill switches are part of the feature, not afterthoughts.
• Ability to 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 skills

Nice To Haves

• Experience being the platform side of a platform/product relationship
• SSE/streaming systems
• Compliance-adjacent engineering (data minimization, auditability)
• Prior Staff scope experience

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.

Benefits

• Competitive Compensation ($205-225k USD or $180-200k CAD per year)
• Syndio Equity
• 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)
