This is a hands-on engineering position for someone who is comfortable working across backend APIs, cloud infrastructure and web applications, with most of the engineering depth focused on serverless backend systems and integrations. You will work closely with engineering, product and compliance specialists to turn complex regulatory and product requirements into reliable production software. This is not a role where architecture is separated from implementation. You will be expected to make sound technical decisions and then help build, test, deploy and operate the resulting software.

Key responsibilities

- Research, analyse and evaluate business and system requirements to design and develop scalable, secure and reliable software solutions.
- Design, develop, maintain and enhance production APIs, backend services and application components in accordance with technical specifications and development standards.
- Design and maintain RESTful APIs, JSON schemas and OpenAPI specifications for reliable communication between internal and external systems.
- Contribute to software architecture and implementation decisions, including evaluating technical approaches, identifying technology limitations and recommending appropriate solutions.
- Write, review and maintain high-quality program code in accordance with system designs, technical specifications and software engineering best practices.
- Develop and maintain serverless and event-driven applications using AWS services including Lambda, API Gateway, EventBridge, DynamoDB, S3, Cognito and Secrets Manager.
- Design and implement secure, multi-tenant application services, including authentication,



authorisation and technical security controls.
- Develop and maintain automated unit, integration and end-to-end tests.
- Investigate production incidents, perform root-cause analysis and implement corrective and preventative measures.
- Collaborate with engineering, product and compliance specialists to understand requirements and develop practical technical solutions.

About you

- A Bachelor's degree or higher in Computer Science, Software Engineering, Information Technology or a closely related discipline.
- At least five years of professional software development experience.
- Strong commercial experience developing software using Node.js and TypeScript.
- Demonstrated experience designing, developing and maintaining APIs and distributed backend services.
- Hands-on experience designing and implementing AWS serverless solutions.
- Strong understanding of data modelling, asynchronous processing and event-driven architectures.
- Experience designing and implementing secure authentication, authorisation and multi-tenant application architectures.
- Strong software engineering fundamentals, including automated testing, source control, code review and maintainable software design.
- Sufficient front-end development experience to contribute effectively to applications built with Angular.
