Original posting from Mapbox via Ashby
Mapbox is the leading real-time location platform for a new generation of location-aware businesses. Mapbox is the only platform that equips organizations with the full set of tools to power the navigation of people, packages, and vehicles everywhere. 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 WE DO
The Navigation Native team builds the high-performance C++ engine that serves as the "brain" of our Navigation SDKs. This library runs directly on end-user systems (on-board), powering everything from mobile apps to in-vehicle infotainment systems for partners like BMW, Porsche, and Zeekr.
We solve the fundamental challenges of movement: transforming noisy GPS/IMU data into precise map-matching, managing complex road-network graphs, supporting routes and alternatives, tracking progress along a route, and providing "Electronic Horizon" capabilities for ADAS. Our work happens at the edge, supporting location frequencies up to 10Hz and ensuring a seamless experience even in tunnels or dense urban canyons.
As AI becomes embedded in modern engineering workflows, we value engineers who can thoughtfully integrate AI into design, development, and decision-making. Our interview process will include discussion of how you use AI in your engineering workflow.
WHAT YOU'LL DO
We are looking for smart, fast-learning engineers who care as much about proving that navigation works as about making it work. As an SDE(T), you will:
- Build and maintain the unit, integration, and functional test architecture for a C++17 library, and the CMake and CI pipelines that run it.
- Turn real-world location recordings into regression tests, and define the quality metrics for map-matching, routing, and route-following.
- Keep the quality signal fast and trustworthy: eliminate flaky tests, run sanitizer and performance builds, and track coverage.
- Build AI-driven test tooling: agent-based test generation, automated dogfooding and triage, and AI-assisted PR review.
- Partner with feature engineers on testability and review designs for how they will be verified.
- Thoughtfully leverage AI tools in your workflow and set the standard for how the team uses them.
WHAT WE BELIEVE ARE IMPORTANT TRAITS FOR THIS ROLE
- Solid C++17 proficiency: comfortable writing test code and tooling, reading production code, and debugging with sanitizers and profilers. Python or similar for harnesses and analysis.
- Proven experience building test infrastructure for a large native codebase: test frameworks, CMake, and CI systems.
- A data-driven mindset: you define metrics, build the tooling to measure them, and use them to argue for or against a change.
- Experience diagnosing hard-to-reproduce failures: flakiness, platform-specific behavior, memory and threading bugs.
- Strong English skills, with the ability to explain test results, risk, and trade-offs to peers and stakeholders.
Would be a Plus
- Familiarity with navigation concepts (map matching, dead reckoning, route progress, or Electronic Horizon).
- Experience with replay- or simulation-based testing using real sensor and GPS data.
- Hands-on experience building AI- or agent-based developer tooling for testing, code review, or triage.
- Experience with coverage tooling, performance benchmarking, or testing SDKs through generated bindings.
WHAT WE VALUE
In addition to our core values https://www.mapbox.com/about/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.
HOW WE SUPPORT YOU
- Hybrid/Remote Options: Enjoy flexibility to work comfortably from home or periodically from an office where applicable.
- Country-Specific Care & Coverage: Private health, dental, and income protection plans tailored to elevate your regional statutory benefits.
- Family-First Support: Family care, maternity and paternity leave policies to support your growing family.
- Lifestyle Spending Account: Contributions to support your health, wellness, and personal growth.
- Balance & Brainpower: Mental health support for you and your dependents.
- Rest & Recharge: Paid time away, company holidays, and generous absence policies.
- Time Off to Give Back: Dedicated paid volunteering time in addition to your standard PTO.
