About us

We believe in creating an inclusive environment where everyone is welcome, regardless of race, colour, religion, gender identity, sexual orientation, national origin, age, or disability.

Our ultimate goal is to make cities for people, not cars, and we need your help to achieve this mission

You will be closely collaborating with key internal stakeholders to determine how to scalably design backend systems and APIs to meet their needs.

Main tasks and responsibilities:

  • Architecting, designing, developing, and deploying Bolt's growing backend systems.
  • Contributing ideas and constructive feedback to our product development roadmap.
  • Helping lead features/initiatives from idea to positive execution.
  • Working closely with Product to slice and dice scope and deliver piece by piece.
  • Sharing your knowledge by giving tech talks, and promoting appropriate tech and engineering best practices in and outside of the team.


We are not really looking for experts, but for cross-language engineers for whom a specific stack is just a tool to solve a problem, not the solution itself.

About you:

  • You thrive in fast-paced, customer-feedback-driven environments with empathy for end-users.
  • You excel in making data-driven, metric-based decisions, and leading initiatives to completion.
  • You have expertise in microservice architecture, API design, and distributed high-volume systems.
  • You have strong principles in writing clean, secure, and maintainable code that is readable and testable.
  • You are experienced with cloud systems (AWS, Azure, Google Cloud) and relational databases.
  • You are familiar with real-time, asynchronous systems, and highly available infrastructure is a plus.

Experience is great, but what we really look for is drive, intelligence, and integrity. So even if you don't tick every box, please consider applying if you feel you're the kind of person described above

Why you'll love it here:

  • Play a direct role in shaping the future of mobility.
  • Impact millions of customers and partners in 600+ cities across 50+ countries.
  • Work in fast-moving autonomous teams with some of the smartest people in the world.
  • Accelerate your professional growth with unique career opportunities.
  • Get a rewarding salary and stock option package that lets you focus on doing your best work.
