Senior or AI Infrastructure Engineer – San Francisco

Build a Safer World.

TRM Labs provides blockchain analytics and AI solutions to help law enforcement and national security agencies, financial institutions, and cryptocurrency businesses detect, investigate, and disrupt crypto-related fraud and financial crime. TRM’s blockchain intelligence and AI platforms include solutions to trace the source and destination of funds, identify illicit activity, build cases, and construct an operating picture of threats. TRM is trusted by leading agencies and businesses worldwide who rely on TRM to enable a safer, more secure world for all.

The AI Engineering Team is chartered with enabling next-generation AI applications
, with a special focus on Large Language Models (LLMs) and agentic systems. Our mission is to build robust pipelines, high-performance infrastructure, and operational tooling that allow AI systems to be deployed with speed, safety, and scale.

We manage petabyte-scale pipelines, serve models with millisecond-level latency, and provide the observability and governance needed to make AI production-ready. We’re also deeply involved in evaluating and integrating cutting-edge tools in the LLM and agent space — including open-source stacks, vector databases, evaluation frameworks, and orchestration tools that unlock TRM’s ability to innovate faster than the market.

As a Senior or Staff AI Infrastructure Engineer
, you’ll be at the core of building and scaling the technical infrastructure for AI/ML systems. You will:

• Build reusable CI/CD workflows for model training, evaluation, and deployment — integrating Langfuse, Git Hub Actions, and experiment tracking, etc.

• Automate model versioning, approval workflows, and compliance checks across environments.

• Build out a modular and scalable AI infrastructure stack — including vector databases, feature stores, model registries, and observability tooling.

• Partner with engineering and data science to embed AI models and agents into real-time applications and workflows.

• Continuously evaluate and integrate state-of-the-art AI tools (e.g. Lang Chain, Llama Index, vLLM, MLflow, Bento
  
  ML, etc.).

• Drive AI reliability and governance, enabling experimentation while ensuring compliance, security, and uptime.

• Build and enhance AI/ML Model Performance

• Ensure data accuracy, consistency and reliability, leading to better model training and inferencing

• Deploy infrastructure to support offline and online evaluation of LLMs and agents — including regression testing, cost monitoring, and human-in-the-loop workflows.

• Enable researchers to iterate quickly by providing sandboxes, dashboards, and reproducible environments.

• Write high-quality, maintainable software — primarily in Python, but we value engineering ability over language familiarity.

• Have a strong background in scalable infrastructure
  , including:

  • Containerization and orchestration (e.g. Docker, Kubernetes)

  • Infrastructure-as-code and deployment (e.g. Terraform, CI/CD pipelines)

  • Monitoring and logging frameworks (e.g. Datadog, Prometheus, Open Telemetry)

• Understand and implement ML Ops best practices
  , including:

  • Model versioning and rollback strategies

  • Automated evaluation and drift detection

  • Scalable model and agent serving infrastructure (e.g. vLLM, Triton, Bento
    
    ML)

• Deploy and maintain LLM and agentic workflows in production, including:

  • Monitoring cost, latency, and performance

  • Capturing traces for analysis and debugging

  • Optimizing prompt/response flows with real-time data access

• Demonstrate strong ownership and pragmatism
  , balancing infrastructure elegance with iterative delivery and measurable impact.
