You will be part of an agile team contributing to the build of digital products, developing new and enhancing existing software components.

Your primary role is to develop clean code, adhering to SOLID principles that are well-tested, performant, and maintainable. You will be developing within an agreed development lifecycle, frameworks, and quality criteria and collaborating readily with other agile delivery team members to enable the right outcome for the customer. This includes working with Quality Assurance to support test automation, DevOps engineers to support security, configuration, and smooth code deployment, also pairing with other team members / new colleagues to assist with knowledge transfer, onboarding, and pair coding/code reviews.

In this role, you will be primarily responsible for:

  • Delivery of high-quality development work results (structure, content, form)
  • Integrating the application front-end services (with a basic understanding of web front-end technologies)
  • Managing the exchange of data between different backend services (owned by separate development teams) and front-end application and third party API integration

  • End-to-end thinking during development - supporting and improving releases from test to integration and production environments
  • Proactive skill and artefact building concerning assessing and adopting new technologies
  • Presentation and demonstration of concepts and services via show-and-tell demos, tech talks, and taking part in direct user feedback and evaluation sessions
  • Providing and collaborating to produce development work estimates
  • Following agile software development lifecycles, but maintaining foresight to reduce tech debt where possible and not at the cost of good documentation, test automation, and non-functional considerations
  • Working under pressure and at pace when required to meet urgent client needs.

  • Demonstrable collaborative team working and taking ownership of delivery commitments and addressing challenges
