Senior AI/ML Engineer LLM & Agent Stack

We're TrueFoundry, and we're building the foundational infrastructure for production AI systems. We're looking for a Senior AI/ML Engineer LLM & Agent Stack to join the team.

Companies are moving beyond simple chatbots to production agentic systems. These systems route between models like OpenAI, Anthropic, Google, and self-hosted models. They integrate dozens of tools via protocols like MCP. They orchestrate multi-agent workflows where agents coordinate with other agents.

The infrastructure to support this doesn't exist yet. You need a control plane that handles:

• Intelligent routing with observability, cost policies, and fallback logic
• Centralized tool and MCP server management with security and lifecycle controls
• Agent orchestration with governance and guardrails
• A unified compute layer to run self-hosted models, custom tools, and agents

We've built two products to solve this:

AI Gateway is the control plane, five composable components (Prompts, LLM Gateway, MCP Gateway, Guardrails, Agent Gateway) that handle routing, orchestration, and governance.

AI Deploy is the compute layer, a Kubernetes-based platform that abstracts ML workloads as standard software primitives, so everything runs on unified infrastructure.

You'll design and own core components that enable enterprise customers to run production agentic AI safely and efficiently on TrueFoundry. This includes building robust orchestration for multi-step agents (graph/stateful workflows), model/routing logic, observability and policy enforcement (cost, data residency, rate limiting), and integrating upstream tooling like LangGraph, LangChain, vector stores, and specialized LLM runtimes.

• Architect and implement scalable agent orchestration patterns (graph-based executors, state management, multi-agent coordination) for production workloads.
• Own critical integrations: model adapters, LLM gateway hooks, vector DBs, tools & external APIs, and the platform's LLMops flows.
• Build and improve tracing, benchmarking and observability for LLMs and agents token/cost accounting, latency p95, throughput, and correctness checks.
• Drive design for safety/guardrails: moderation hooks, human-in-the-loop checkpoints, replayable audit trails and policy enforcement.
• Mentor junior engineers, run design reviews, and improve engineering practices (testing, CI/CD, chaos testing for agents).
• Work directly with strategic customers to prototype complex agentic solutions and translate them into product features.

• 58 years of software engineering with substantial experience building distributed systems, infra, or ML platforms.
• Deep practical experience integrating and deploying LLMs in production (RAG, retrieval, embeddings pipelines).
• Hands-on experience with agent orchestration frameworks (LangGraph / LangChain or custom agent runtimes) and stateful workflow design.
• Strong systems knowledge: Kubernetes, container orchestration, service meshes, and performance tuning.
• Proven track record building observability, cost controls, and policy enforcement for production services.

• Experience building or contributing to open-source LLM orchestration tools (LangGraph, LangChain, or similar).
• Familiarity with enterprise constraints: on-prem/cloud hybrid deployments, data residency, compliance requirements.
• Background in security, privacy, or model governance for LLMs.
• Demonstrated leadership in cross-functional projects and direct customer engagement.

• BS/MS/PhD in CS or related field (or equivalent).
• Open-source contributions, architecture blogs, or public talks on agentic LLMs or LLMops.
• Examples of productizing research or shipping complex infra features.
