Our mission: Make cities more responsive, so they are safer, healthier, and more equitable for the people who live in them.

Numina makes a hardware and software platform that uses computer vision to help urban planners and municipal governments design better (safer) streets and public places. We sense bicycle, pedestrian, and other street traffic, and convert this data into real-time intelligence — without surveillance — to enable all sorts of partners in automation, autonomy, and development in the public right-of-way. We are looking for passionate people who would like to join us as we pursue our shared vision of more responsive cities.

As Backend Engineer, you will help design, build, and optimize our APIs and data processing systems. You will collaborate with the rest of the engineering and product teams to extend and improve our product’s capabilities.

  • Update, extend and optimize existing API as necessary to support existing and planned needs of other systems (sensors, dashboards, maps, etc.).
  • Update existing or create new APIs as necessary to support third-party application development.
  • Help guide new application development with external partners focused on real-time services.
  • Manage and tune infrastructure, making use of managed services wherever appropriate (e.g. Amazon ECS, Lambda, IoT, Kinesis, DynamoDB, Redshift, etc.).
