More than 4 million registered developers have chosen Mapbox because of the platform’s flexibility, security and privacy compliance. Organizations use Mapbox applications, data, SDKs and APIs to create customized and immersive experiences that delight their customers.

What Do We Do

The Data Tooling team owns a variety of services for review, validation and editing of Mapbox’s global basemap content with the aim of delivering our customers the most accurate, and continuously updating Live Map of the world. We rely on our robust data processing pipelines and suite of proprietary tools that we have built over the years that allows us to validate millions of data updates per month, process thousands of weekly user feedback from vehicles and mobile devices, and annotate millions de-identified user sessions and telemetry to make them machine readable and extract insights at scale.

We are seeking an experienced engineer to partner with a passionate group of software engineers to own, build, and grow out capabilities of our mapping tools to the next level.

Your Responsibilities Will Include

Drive the design, development, and testing of Mapbox tools and services for triaging and applying fixes for customer’s feedback as well as applying corrections on the top of third party data.
Solve complex workflow problems and implement enhancements in frontend and backend services based on evolving business requirements, metrics and user feedback.
Establish operational metrics that ensure your services are performing as expected and continuously drive improvements.
Maintain documentation for your services.
Collaborate with the in-house editors team to understand their workflows, gather pains and gains for everyday usage of services you are developing.

What we believe are important traits for this role

5+ years of experience as a full-stack software engineer.
Proficiency in JavaScript and modern frontend frameworks such as React.
Proficiency with server-side development in Node.js (Nest.js/Express.js).
Experience with cloud services (Amazon AWS, Microsoft Azure, Google Cloud) and associated technologies (Docker, Kubernetes).
Strong understanding of UI/UX principles and best practices.
Good understanding of client-side state management, asynchronous tasks and side effects.
Understanding of REST architecture, SPA approach, micro-frontend architecture, common software design patterns.
Experience with testing frameworks (eg. Jest/RTL/Cypress).
Familiarity with modern engineering best practices (build systems, CI/CD, etc). Good understanding of how to build robust software.
Strong English verbal and written communication skills. Mapbox has offices in the USA, Finland, Japan and Belarus. You should clearly communicate complex ideas to a worldwide audience. Similarly, you should explain your work in detail and walk through decisions with teammates and collaborators.

Would be a plus

Experience with TypeScript.
Experience with project management tools: Jira is preferred.
Would be a heavy plus an experience of working with GeoJSON and understanding of OSM tools ecosystem.

What We Value

In addition to our core values, which are not unique to this position and are necessary for Mapbox leaders:

We value high-performing creative individuals who dig into problems and opportunities.
We believe in individuals being their whole selves at work. We commit to this through supportive health care, parental leave, flexibility for the things that come up in life, and innovating on how we think about supporting our people.
We emphasize an environment of teaching and learning to equip employees with the tools needed to be successful in their function and the company.
We strongly believe in the value of growing a diverse team and encourage people of all backgrounds, genders, ethnicities, abilities, and sexual orientations to apply.

🎯 Who is this job for?

This role is ideal for a Full Stack Engineer with 5+ years of experience, proficient in JavaScript, React, and Node.js (Nest.js/Express), with knowledge of cloud platforms like AWS, Docker, and Kubernetes. Candidates should be comfortable with UI/UX best practices, REST APIs, testing frameworks, and modern dev workflows. Bonus for experience with TypeScript, SQL/NoSQL, and geospatial tools like GeoJSON or OpenStreetMap.

💬 Potential Interview Questions

What are the benefits of using Nest.js over Express.js in full-stack development?
Nest.js provides a modular architecture, dependency injection, and TypeScript support out of the box, making it ideal for large-scale, maintainable applications compared to the minimalist, unstructured approach of Express.js.
How do you handle client-side state and side effects in complex React applications?
I use state libraries like Redux or Zustand, and manage side effects using middleware like Redux-Saga or tools like React Query, ensuring separation of concerns and predictable updates.
Describe your experience with containerizing services using Docker and deploying to Kubernetes.
I write Dockerfiles with multi-stage builds, use docker-compose for local dev, configure Kubernetes deployments with Helm charts, and manage autoscaling and rollbacks using Kubernetes tools.
What are some best practices when designing RESTful services in a full-stack app?
Use clear resource naming, consistent HTTP methods, proper status codes, stateless authentication (JWT), pagination for large datasets, and versioning for backward compatibility.
How do you implement frontend testing in React using tools like Jest, RTL, or Cypress?
I use Jest for unit tests, React Testing Library for DOM testing, and Cypress for end-to-end tests, aiming for meaningful coverage on user flows and regression points.
Explain how you would optimize a Mapbox data review tool for performance and usability.
I’d profile frontend rendering, implement lazy loading, debounce user input, cache common data, optimize API queries, and collaborate with editors to refine UX based on real-world usage.
What experience do you have working with cloud platforms like AWS or GCP in production systems?
I’ve used AWS for EC2, Lambda, S3, CloudWatch, and RDS; managed infrastructure with Terraform; and deployed services with CI/CD pipelines using GitHub Actions and GCP Cloud Build.
How would you architect a micro-frontend application for mapping tools?
Use independent modules (e.g., Webpack Module Federation), define clear contracts via shared libraries, isolate state, and coordinate releases through a central host shell.
Have you worked with GeoJSON or OpenStreetMap tools? How did you use them?
I’ve used GeoJSON for rendering geospatial data layers, and integrated OSM-based tools like Leaflet and Overpass API for live data visualization and editing workflows.
Describe a complex problem you solved in a distributed system or map data pipeline.
I optimized a validation service by batching map tile updates, parallelizing ingestion, and implementing a retry mechanism to handle flaky upstream data inputs, cutting processing time by 40%.
