About the team

The R&D center of the company is divided into many teams, including:

• Rides — a transport application for booking fast and affordable rides.
• Rentals — car sharing and electric scooter rental system.
• Food — food delivery service.
• Commerce — a system for processing payments and various transactions.

And many others.

It is worth noting that teams are not tied to a specific programming language, considering it rather a means to achieve global goals, and what is really important for them is the presence of a strong algorithmic base and the desire to develop a cool product.

All services of the Bolt product are built on the principle of microservice architecture and implemented in the cloud infrastructure (AWS, Azure, Google app engine). Some of them use real-time data processing, others work on an asynchronous model.

Responsibilities

• Architecting, designing, developing, and deploying Bolt's growing backend systems.
• Collaborating with key internal stakeholders to determine how to scalably design backend systems and APIs to meet their needs.
• Coding mostly in Node.js and TypeScript (previous experience with Node.js is not required).
• Contributing ideas and constructive feedback to their product development roadmap.
• Sharing your knowledge by giving tech talks, and promoting appropriate tech and engineering best practices in and outside the team.
• Helping lead feature/initiatives from idea to positive execution.
• Working closely with Product to slice and dice scope and deliver piece by piece.

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

Requirements

• Thrive in an environment that has a fast customer-feedback cycle and having empathy for the end-user.
• Experience in making data-driven and metric-driven decisions.
• A drive for leading initiatives and features till the end, even if the last mile is the hardest.
• Experience in a microservice architecture.
• Strong principles towards writing clean, simple, secure, and maintainable code.
• Experience in API design.
• Having a deep understanding of how to write readable, testable, maintainable, and performant code.
• 5+ years of experience in software development.
• Solid understanding of algorithms and data structures.
• Ability to reason from first principles and grow based on previous learnings.
• Thrive in a culture of well-intended reciprocal feedback.
• Good English and communication skills.
• University degree in a technical subject (Computer science, Mathematics, or similar) or equivalent experience in the industry.

Nice to have:

• Familiarity with any cloud systems (AWS, Azure, Google app engine).
• Interest in real-time and asynchronous systems.
• Experience in working with relational databases.
