Responsibilities
Help build the services and integrations that power RoadWarrior’s route optimization platform and the APIs that comprise the MapQuest for Developers ecosystem
Design and implement scalable backend systems in Node.js: Develop modern backend services using Node.js (with TypeScript preferred) optimized for scale, low latency, and reliability
Work with MongoDB at scale: Design and optimize data structures primarily using MongoDB. Some legacy SQL systems are still in use, so familiarity with relational databases is a plus, though most day-to-day work is with NoSQL
Build and operate distributed systems: Architect and deploy highly scalable APIs and services used by internal products and external developer customers
Deliver end-to-end ownership: Take projects from planning and architecture through implementation, deployment, and ongoing support
Collaborate across teams: Work closely with engineers, product managers, and stakeholders across both product lines to solve complex backend and data challenges
Adapt quickly in an agile environment: Operate with autonomy while contributing to lightweight, agile planning and prioritization processes
Qualification
Required
5+ years of backend development experience, with a proven record of building systems at scale
3+ years of production experience in Node.js, ideally with TypeScript
2+ years of experience with NoSQL databases, especially MongoDB
Commitment to code quality: You follow engineering best practices, write clean and maintainable code, and are comfortable in Git-driven workflows
Strong communication and organizational skills: You can clearly articulate ideas, lead discussions, and manage your time effectively
Preferred
Familiarity with GraphQL, even if not used day-to-day, is appreciated
Experience with mapping and geolocation APIs (e.g., MapQuest, Google Maps, OpenStreetMap) is a major plus
