Senior Software Engineer, AI Platform - US

• 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).


• 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.


• Nice to have: experience being the platform side of a platform/product relationship; SSE/streaming systems; compliance-adjacent engineering (data minimization, auditability); prior Staff scope.

Core Competencies

Demonstrates expertise in building production backend systems with a focus on Python, GCP, and compliance requirements. Capable of designing operable systems that integrate LLM technologies and ensure reliability and observability.
