What We Do

Mapbox is looking to hire motivated, curious, and innovative Software Development Engineer for the Navigation, Traffic team.

This is a highly multidisciplinary team, with work spanning distributed systems on AWS to geospatial localization, traffic telemetry, and mapping.

What You'll Do

As a Software Development Engineer II on the Navigation Traffic team, you will be responsible for balancing rapid development of new navigation solutions against the reliability of our services as they scale into new request volumes, markets, and use cases.

• Promote a culture of operational excellence by meticulously testing and monitoring our systems and code, writing documentation, and being on‑call to support the health of our services
• Reduce technical debt, share your knowledge, and invest in your teammates’ health and happiness, while optimizing application performance and accelerating feature velocity
• Uphold a culture of collaboration, transparency, creativity, inclusion, and data‑driven decisions

What We Believe are Important Traits for This Role

• 5+ years of experience building scalable high volume low latency backend services
• Proficiency in our tech stack — Python, TypeScript (backend), AWS (CDK/ECS/Step Functions/Lambda/S3)
• Familiarity with code versioning tools, such as GitHub
• Ability to engage, learn and contribute quickly to the initiatives
• Able to perform independently all the development tasks, based on designs and specs.
• Self‑starter who is communication and outcomes‑oriented
• An empirical analytical approach. You develop strong hypotheses, conduct spikes, and clearly communicate your findings
• A desire to share your expertise through documentation, mentorship, pairing and both written and verbal discussion
• A desire to work with individuals with diverse backgrounds, perspectives, and experiences
• High quality mindset — write unit tests, proactively remedy defects and follow through to production

Nice to Have Traits for This Role

• Experience and knowledge within the navigation domain
• Experience with Amazon Elasticache
• Experience with SQL
• Experience with Big Data/ML
• Experience with various security standards and associated technical knowledge

• 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.
