Descrição da oferta de emprego

TRM Labs is a blockchain intelligence company committed to fighting crime and creating a safer world. By leveraging blockchain data, threat intelligence, and advanced analytics, our products empower governments, financial institutions, and crypto businesses to combat illicit activity and global security threats. At TRM, you'll join a mission-driven, fast-paced team made up of experts in law enforcement, data science, engineering, and financial intelligence, tackling complex global challenges daily. Whether analyzing blockchain data, developing cutting‑edge tools, or collaborating with global organizations, you’ll have the opportunity to make a meaningful and lasting impact.

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 approximately one week every 4 weeks.
• Frontend usually doesn't get pager duty alerts but gets frontend issues from customer support channels and the on‑call is responsible for triaging if it is a frontend bug or sometimes really a backend issue.
• It gets busy during some on‑call weeks but has not been wake‑up from sleep type of alerts.

Learn about TRM Speed in this position:

• The team was tasked to deliver a critical project. Initial estimates were that it would take 2 months. Through ruthless prioritization, bringing in additional resources to help with implementation, and iterating with the Product to descope features from our milestone, we were able to deliver within two weeks and continue to iterate on the rest of the milestones. The project delivered immediate value in sales conversations.
• During project execution, engineers often have questions for their design and product counterparts. This back and forth could take hours or days to get everyone on the same page, but at TRM we short circuit by ensuring that engineers feel empowered to also drive decision‑making across product and design. They analyze the issue and propose solutions and are able to drive the discussion forward and build alignment much faster.
• We have a large group of power users internal to the company who provide us with product feedback. When our engineering team hears of a pain point from this group, they’re empowered to ship these minor improvements directly to this beta group without seeking multiple levels of approval.

About TRM's Engineering Levels:

Engineer: Responsible for helping to define project milestones and executing small decision 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.
