Senior Machine Learning Engineer, Knowledge Layer

Build a Safer World.

TRM Labs provides AI-powered intelligence solutions that help public and private sector agencies investigate and disrupt crime. TRM's platforms enable investigators to trace illicit activity, build cases, and construct operating pictures of threat networks. Leading agencies and businesses worldwide rely on TRM to make the world safer and more secure.

We’re looking for a Full Stack Data Scientist / Machine Learning Engineer to join our Knowledge Layer team, a group focused on extracting, structuring, and analyzing knowledge from large-scale, unstructured data. This team sits at the intersection of knowledge graphs, entity resolution, graph extraction, and graph analytics, and plays a critical role in powering TRM’s core intelligence products.

While the team has strong backend and graph engineering expertise, we are looking for someone to be the machine learning and data science voice in the room — bringing practical ML expertise, especially in knowledge extraction and graph-based ML, to help accelerate and scale our capabilities.

This is an ideal role for someone who enjoys operating end-to-end: from model selection and experimentation, to productionizing ML systems and APIs.

The impact you will have:

Design, build, and productionize machine learning models focused on:

Knowledge extraction from unstructured data (e.g., NER, entity linking)

Graph-based learning and inference

Entity resolution and relationship discovery

Evaluate and leverage existing ML models and frameworks to solve real-world problems efficiently

Partner closely with backend and graph engineers to integrate ML models into production services and APIs

Contribute to the design and evolution of knowledge graphs and ontologies

Perform exploratory data analysis (EDA) to inform modeling decisions and system design

Own ML components end-to-end, including experimentation, evaluation, deployment, and iteration

Help shape best practices for applied ML within the Knowledge Layer team

What we’re looking for:

5+ years of experience in data science, machine learning engineering, or applied ML

Strong programming experience in Python

Hands-on experience building, training, or deploying machine learning models in production

Familiarity with NLP or information extraction techniques, such as Named Entity Recognition (NER), text classification, or embedding-based approaches

Experience or strong interest in knowledge graphs, graph data, or graph-based ML

Solid software engineering fundamentals, including building and maintaining APIs or services

Ability to translate ambiguous problem spaces into practical ML solutions

Strong communication skills and comfort collaborating with engineers across disciplines

AI Fluency at TRM

AI fluency is a baseline expectation at TRM.

We believe AI meaningfully changes how top performers operate. We expect every team member to use AI to accelerate and reimagine their craft, not just automate surface tasks.

At TRM, AI fluency means you are among the top 10 percent of operators in your function in how you apply AI to:

Accelerate repeatable workflows

Structure and solve problems

Improve output quality

Increase speed and leverage

You will be evaluated on applied AI fluency during the interview process.

Life at TRM

We are building a safer world. That promise shows up in how we work every day.

TRM moves FAST. We are a high-velocity, high-ownership team that expects clarity, follow-through, and impact. People who thrive here are energized by hard problems, experimentation, and continuous feedback. If something takes months elsewhere, it will ship here in days.

Our work sits at the intersection of AI, national security, and fighting crime. The problems are complex, the stakes are real, and the environment evolves quickly. The pace and intensity of the work reflect the importance of the mission. As a result, the way we operate requires a high level of ownership, adaptability, collaboration, and creative problem-solving.

At TRM, you should expect:

Priorities and targets to change quickly

Operating with a high degree of ambiguity

A high level of personal ownership and accountability

Close collaboration across teams and functions

Frequent, high-touch communication

Creative problem-solving and out-of-the-box thinking

A pace that rewards urgency, adaptability, and outcomes

This environment is energizing for people who enjoy building, solving hard problems, and making progress in situations that are not always fully defined. It also requires thriving in ambiguity, adjusting course as new information emerges, and maintaining focus and positivity in a fast-moving and intense environment.

We also recognize that this style of operating is not for everyone. If you are primarily optimizing for predictability or a consistently balanced workload, we encourage you to use the interview process to pressure-test whether this environment is truly the right fit. We want teammates who thrive here, not just survive here.

If you are excited by meaningful problems, motivated by ambitious goals, and energized by working alongside mission-driven colleagues, there is a good chance you will find TRM to be an exceptional place to grow and contribute.
