Senior Backend Software Engineer, MapQuest

Role

System1 is seeking a dynamic Senior Backend Engineer to join our MapQuest B2B team. This role supports two of our core offerings:

RoadWarrior by MapQuest , a route optimization platform for delivery professionals and SMBs.

MapQuest for Developers , a suite of robust APIs that power geolocation, routing, traffic, and map rendering services for developers globally.

As part of System1, MapQuest blends the innovative spirit of a startup with the revenue and reach of an established company. We’re expanding rapidly, and we’re looking for an engineer eager to help shape the future of both a route-optimization product and a large-scale API platform that supports a global developer community.

If you thrive in a fast-paced environment, are driven by innovation, and want to help scale platforms used by builders and businesses alike, we’d love to hear from you!

The Role You Will Have

• 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.
  
  

What You Will Bring

• 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.
• Bonus: Familiarity with GraphQL, even if not used day-to-day, is appreciated.
• 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.
• Experience with mapping and geolocation APIs (e.g., MapQuest, Google Maps, OpenStreetMap) is a major plus.
• Open source contributions are welcome!
