Job description

Senior Software Engineer (Java, React, AWS)

Location: Nottingham, UK Employment Type: Full-time


About the Role

As a Senior Java Software Engineer, you will make an impact by designing and delivering robust, scalable web applications and microservices-based solutions that meet the highest standards of quality, security, and performance. You will be a valued member of our engineering team and work collaboratively with developers, architects, graphic designers, and cross-functional stakeholders to design, launch, and continuously improve innovative digital products.

In This Role, You Will:

  • Develop and implement tasks and components of projects in line with client requirements, writing zero-defect code and comprehensive unit test cases to ensure first-time-right delivery within defined timelines, security, and performance guidelines.
  • Design the overall architecture of web applications, applying microservices principles and established design patterns to deliver scalable, maintainable solutions.
  • Develop and maintain business layer coding, interface development, service development, and stored procedures, raising issues proactively and seeking peer review to continuously improve output quality.
  • Write and execute unit test cases, capture and resolve defects, and support integration and automation testing throughout development, SIT, UAT, and warranty phases.
  • Understand, interpret, and clarify both functional and technical requirements; provide effort and timeline estimates for assigned tasks; and support proof-of-concept development with relevant stakeholders.
  • Identify and highlight potential risks to technical leads in a timely manner; support the integration of components; maintain traceability matrices; and adhere to SCM policies, process tools, and Quality Management System standards.
  • Collaborate with graphic designers to convert designs into polished visual elements, and contribute to the implementation of security and data protection measures across the application.
  • Contribute to the development and maintenance of knowledge assets, including user manuals, installation scripts, and online documentation; actively contribute to and reuse assets from the team repository.
  • Provide ideas for process optimisation and value-add initiatives, sharing them with relevant stakeholders while promoting adherence to tools such as Cognizant 2.0 and established IDE standards.
  • Improve core technical skills on an ongoing basis, keeping pace with evolving technology landscapes including Gen AI tooling, cloud platforms, and DevOps practices.

Work Model

Based on this role's business requirements, this is a hybrid position based at Nottingham office - 3 days office and 2 days WFH.


What You Need to Have to Be Considered

  • Extensive hands-on experience with Core Java / Java 8 and Spring Boot, with a strong command of object-oriented principles and application architecture.
  • Good experience with React JS and front-end technologies, including converting design assets into responsive visual elements.
  • Strong experience with CI/CD pipelines and modern DevOps practices, including version control tools such as GitHub and Jenkins.
  • Strong knowledge of Microservices architecture and established design patterns, including experience building and consuming RESTful web services.
  • Strong understanding of API design and security, including data protection implementation.
  • Good experience with database technologies and API integration, including the ability to develop and maintain stored procedures.
  • Good working knowledge of cloud platforms (e.g. AWS) and observability practices, including monitoring and performance management.
  • Good understanding of SRE principles and Agile delivery methodologies, including experience working with tools such as Jira.
  • Strong verbal and written communication skills, with the ability to engage effectively with technical and non-technical stakeholders.
  • Good experience with testing practices, including unit testing, code coverage tools, and UI test scripts.
  • A relevant graduate degree or equivalent practical experience.

Additional eligibility requirements:

  • Candidates must currently reside in the UK.
  • Candidates must be available to start within eight weeks of receiving an offer.

These Will Help You Stand Out

  • Good experience with Kubernetes for container orchestration in production environments.
  • Fair knowledge of Apache Kafka for building event-driven, distributed systems.
  • Familiarity with Gen AI tools such as Claude, with an interest in applying AI-assisted development practices.
