You are passionate about API Standards, Test Driven Development and have strong opinions on the right way to build and operate services. You will write code, design systems, build out proof of concepts, compare and contrast technology alternatives that improve systems and automation throughout our products and tech stack.

• Follow the engineering best practices as defined by the team and organization, from testing, deployment, documenting, operating services and code quality.
• Participate in code reviews and provide constructive feedback to team members.
• Participate in a team-wide on-call rotation.

Who you are:

• 1-2 years experience working as a Software Engineer.

• Strong core Java skills (knowledge of GO is highly desirable).
• Experience in designing and implementing APIs and Microservices.
• Understanding of the full software development life cycle (scoping, prioritisation, planning, execution, operation, end-of-life) and the tools that assist it (source control, continuous integration, deployment tools) in an Agile environment.

Bonus points:

• Experience with JavaScript and FrontEnd technologies like React, Redux, Redux-Saga, Hooks, TypeScript, ES6, SASS (and more).
• Experience of Cloud technology (AWS or similar).
