The posting, as Mapbox wrote it

Mapbox is the leading real-time location platform for a new generation of location-aware businesses.

Organizations use Mapbox applications, data, SDKs and APIs to create customized and immersive experiences that delight their customers.

WHAT YOU'LL DO

This role is scoped by skill rather than by product. The problems below span multiple departments and show up across our Search and Places data work, our Location and Navigation Intelligence work, and the Platform work that makes Mapbox usable by agents. You'll be hired into one specific team or product area, but you'll work across teams where your expertise meets the highest-priority AI problems. You should expect to move between teams and tech stacks as the work demands.

At this level you own the technical design and delivery of a multi-component AI system, and you are accountable for the quality of what ships in your area.

IN THIS ROLE, YOU WILL

• Define how the products you own should work, build a measurement framework for it, and build evaluation systems for non-deterministic behavior. Formulate hypotheses around the products we build and seek the signal needed to validate them. Define what a correct result is for a given input and state, determine whether to assemble datasets from real usage or hand-written cases, and gate changes on regression results.
• Run continuous evaluation of the products we build, whether APIs, SDKs, data representations, or reference applications, from the position of the end user, whether developer, agent, or consumer. Assess the gaps such as misuse of parameters or integration anti-patterns, recommend the fixes, and make sure they land.
• Own the MVP against an agreed north star technical design, and balance technical perfection against shipping useful increments.
• Build data pipelines and the tooling around them: ingestion, conflation, entity resolution, quality checks, and the batch and streaming jobs that keep a large dataset current.
• Track and pull external datasets, models, and benchmarks from published research and open-source releases. Evaluate what fits the problem and constraints , and decide when to adopt what exists versus build your own.
• Design feedback loops so that using a product generates data that improves it. Instrument systems so failures arrive with enough context to reproduce, then turn the recurring ones into evaluation cases.
• Design the boundary between a model and the tools it calls. Build or improve the model harness, decide what the model handles, what it delegates, and how to keep it working from the state it actually fetched.
• Work to a latency and cost target per request: streaming, partial results, caching, mod

• Comprehensive Healthcare: Private medical coverage for you and your dependents.
• Family-First Support: Generous maternity and paternity leave policies to support your growing family.
• Fertility & Family Building: Inclusive fertility support. Grow your family on your terms.
• Lifestyle Spending Account: Contributions to support your health, wellness, and personal growth.
• Balance & Brainpower: Mental health support for you and your dependents.
• Rest & Recharge: Flexible paid time away, company holidays, and generous absence policies.
• Time Off to Give Back: Dedicated paid volunteering time in addition to your standard PTO.
• Invest & Grow: Retirement plans with competitive matching.

Our annual base compensation for this role ranges from $175,100 - $236,900 for most US locations and 5% to 10% higher for US locations with a higher cost of labor. Job level and actual compensation will be decided based on factors including, but not limited to, individual qualifications objectively assessed during the interview process (including skills and prior relevant experience, potential impact, and scope of role), market demands, and specific work location. Please discuss your specific work location with your recruiter for more information.
