- Proficiency with GraphQL, TypeORM, and Nest.js.
- Hands-on experience working with (and administering) K8S, message brokers (RMQ), APIs, especially proprietary hardware or device integrations is a plus.
- Excellent debugging and problem-solving skills across software and hardware domains.
- Ability to self-organize and manage tasks in a fast-paced, ticket-driven environment.
- Ability to write clean code and effective automated tests to deliver high-quality system improvements.
- Ability to break down larger requirements into small, self-contained changes to the system.
- Excellent spoken and written communication skills.
- Experience in the retail and/or fuel & convenience industries a plus.
- Ruby/Rails experience a big plus.
- Experience implementing or consuming GraphQL APIs a plus.
Benefits
- Build and maintain backend services and API.
- Collaborate with product managers, designers, and other engineers to deliver end-to-end solutions.
- Investigate and resolve production issues and customer-reported bugs with a focus on root-cause analysis and long-term maintainability.
- Contribute to system design discussions and architectural decisions.
- Continuously improve code quality, testing practices, and development processes.
