Build to Protect Civilization

TRM is a blockchain intelligence company that’s on a mission to build a safer financial system for billions of people. We’re a lean, high-impact team tackling some of the world’s most critical challenges, ranging from human trafficking and financial fraud to terrorist financing. We are builders who power governments, financial institutions, and crypto companies when the clock is running and the consequences are real. This is why every TRMer is a bet on our future and has the power to change our trajectory.

About the Position

We are looking for an experienced Senior Frontend Engineer to join a small but fast-growing Frontend Engineering team that is responsible for building highly robust and seamless product features that analyze blockchain transaction activity at a massive scale. As an early member of the team, you will be deeply involved in the technical details and ultimately champion your team to build a safer financial system for billions of people.

The impact you’ll have here:

  • Building a large-scale web application that manages billions of transactions using React and Redux
  • Working with Backend Engineers, Designers, and Product to build features and ship product
  • Finding and addressing performance issues
  • Participating in code and design reviews
  • Developing a deep understanding of crypto and blockchain to inform product design and direction
  • Collaborating with product lead and customers to define a new category of enterprise software
  • Staying current on frontend best practices

What we’re looking for:

  • Knack for great design and intuitive UX
  • Strong Computer Science fundamentals
  • Extensive experience modern front end frameworks (e.g., Vue.js, React.js) and CSS-in-JS libraries (e.g., styled-components)
  • Experience designing and building data heavy front-end applications
  • Experience with virtual currencies, applications, and their use in financial networks and blockchain analysis is a plus
  • Adaptable. Goals can change fast. You anticipate and react quickly.
  • Autonomous. You own what you work on. You move fast and get things done.
  • Excellent communication. You will need to communicate complex ideas effectively to both technical and non-technical audiences, and both verbally and in writing
  • Collaborative. You must work collaboratively in a cross-functional team and with people at all levels in an organization

About the Team:

  • The team operates on a weekly sprint schedule. Individuals on the team are tasked to lead projects as technical anchors, and given a chance to grow and take ownership according to their level and goals. 
  • We work closely with product, design, and with our engineering partners in data platform teams to deliver impactful features to customers and the company.
  • The team’s timezone is a mix of EST and PST, with at least 6 hours of overlap with PST (8 am to 2 pm PST).
  • On-Call: We have an on-call rotation that is a week long in duration approximately once every 4-6 weeks. On-call requests can be categorized into two large buckets; a) PagerDuty alerts that warrant immediate attention and b) customer support requests from specific Slack channels that an on-call engineer is responsible for triaging and answering.

Learn about TRM Speed in this position:

  • Ruthless Prioritization & Adaptability: We adapt quickly when faced with new information. For example, an engineer may message the PM or EM to prioritize Task A vs. Task B in the middle of the sprint – we don’t let inertia guide our decisions. Instead we focus on ruthless prioritization and pivot quickly as needed.
  • Challenging Timelines (Execution Pressure): An engineer questions a teammate’s proposed 3-week timeline, and constructively argues for condensing it to 2 weeks—backed by rationale, tradeoffs, and a plan to reduce scope or increase velocity. They show ownership of delivery speed and willingness to push for urgency.
  • Time-Boxed Spiking (Rapid Learning & Decision-Making): An engineer proposes a 1-week spike with a clear time-box and success criteria to explore implementation options or validate feasibility through a proof of concept. They demonstrate speed not just in execution, but in de-risking decisions early.

About TRM's Engineering Levels:

Engineer: Responsible for helping to define project milestones and executing small decisions independently with the appropriate tradeoffs between simplicity, readability, and performance. Provides mentorship to junior engineers, and enhances operational excellence through tech debt reduction and knowledge sharing.

Senior Engineer: Successfully designs and documents system improvements and features for an OKR/project from the ground up. Consistently delivers efficient and reusable systems, optimizes team throughput with appropriate tradeoffs, mentors team members, and enhances cross-team collaboration through documentation and knowledge sharing.

Staff Engineer: Drives scoping and execution of one or more OKRs/projects that impact multiple teams. Partners with stakeholders to set the team vision and technical roadmaps for one or more products. Is a role model and mentor to the entire engineering organization. Ensures system health and quality with operational reviews, testing strategies, and monitoring rigor.

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
