• Collaborating with other engineers, PMs and teams internationally and cross functionally to deliver a high quality experience to our customers

• Promoting a culture of operational excellence by meticulously testing and monitoring our systems and codes, and being available/on-call to support the health of our services

What We Believe are Important Traits for This Role

• Strong understanding of search techniques (such as information retrieval) and data structure

• Practical experience in making an algorithm perform efficiently upon implementation

• Ability to write sophisticated, highly performant, and reliable solutions

• Excellent problem solving skills and analytical skills, valuing a scientific approach by using experimentation and critical thinking to drive and validate high quality solutions

• Experience with at least one modern programming languages such as JAVA, C++, Rust

• Proficiency in implementing monitoring instrumentation, operational diagnostics, resolving customer issues, and continuous product improvement

• Fluent communication in English with a sense for listening to others as well as getting your message across concisely

• Familiarity with the Japanese address system

For this position, the following skills would be preferred but are not required:

• Experience with maps, routing, navigation

• Experience with NLP/ML/Generative AI

• Experience with search engines such as ElasticSearch, Solr, Lucene

• Experience with solving challenging search problems

• Experience with big data and scale, data mining and science

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.
