Senior Software Engineer - AI Platform Team

What you’ll be doing (ie. job duties):

• LLM Gateway: one API for 60+ models across all major providers, including self hosted open weight models, with auth, PII redaction, quotas, fallbacks, and cost optimization
• AI Hub: single front door for agents, skills, MCP servers, knowledge bases, models, memories, and keys
• Agent and MCP runtime: microVM sandboxes per agent run, a governed MCP gateway over 125+ servers, cross trust agent identity, tier 1 agents for code, analytics, and exec personas
• Knowledge Bases: connect any data source, auto provision vector and markdown stores, queryable by any agent over MCP
• AI Spend Hub: FinOps for AI, spend attribution and governance across the company
• Evaluation and observability: in house LLM as judge harness with full tracing and eval tooling
• Company wide chat and low code workflow surfaces, thousands of weekly actives each
• Applied AI: we embed with teams to build production agents, build the feedback loops that let subject matter experts refine them, and apply traditional ML including fine tuning where it beats prompting

What we look for in you:

Own multi quarter, high impact initiatives on the platform (gateway, runtime, knowledge, governance) or the applied agents on top. Partner across engineering, security, legal, finance, and product, and work directly with our partners at the frontier labs and major cloud providers.
