About the Team: The team operates on a weekly sprint schedule. Individuals on the team are tasked with leading projects as technical anchors and given opportunities to grow and take ownership according to their level and goals. We work closely with product, design, and 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) We have an on-call rotation that is a week long in duration approximately once every 16 weeks. On-call requests can be categorized into two large buckets; a) PagerDuty alerts that warrant immediate attention 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 – w e 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. Life at TRM We are building a safer world. That promise shows up in how we work every day.
