Swansea, United Kingdom | Posted on 28/05/2026

Scrumconnect Consulting is a multi-award-winning digital consultancy whose work has positively influenced the lives of over 40 million UK citizens. We deliver impactful technology solutions across UK government departments, working at the forefront of user‑centred design, agile delivery, and scalable digital services that genuinely make a difference.

Location:

Swansea (with a regular expectation of 60% on‑site attendance).

Strong focus on work‑life balance with a flexible hybrid model (3 days onsite).

Be part of a collaborative, multidisciplinary agile environment alongside civil servants and industry experts.

Based in Swansea, South Wales — three days per week on‑site.

We are seeking a technically deep, automation‑first Software Development Engineer in Test (SDET) to embed within a blended digital delivery squad of civil servants and supplier staff. In this role, you will design, build, maintain, and continuously improve the automated test frameworks and quality‑engineering practices that underpin high‑volume, citizen‑facing digital services handling billions of interactions annually. You will own the full testing lifecycle from strategic planning through to continuous integration and continuous deployment (CI/CD) pipeline integration.

Working alongside software engineers, architects, and product owners, you will ensure that quality is built‑in from the start, rather than bolted on at the end. You will be expected to code in the languages used across our modern tech stack and maintain a strong grasp of API, performance, security, and accessibility testing.

• Framework Development:
  Design, build, and maintain automated test frameworks covering functional, regression, API, integration, performance, and security testing.
• Pipeline Integration:
  Embed automated tests within CI/CD pipelines (e.g., Jenkins or Git Hub Actions) to ensure continuous quality feedback and facilitate fast build cycles.
• Strategy & Planning:
  Define and own the test strategy for assigned digital products, ensuring appropriate test coverage across unit, integration, system, performance, and accessibility layers.
• Specialised Testing:
  Lead API testing for REST/GraphQL services using tools like Rest Assured, Postman, or Karate, and execute performance/load testing using Gatling, k6, or JMeter to validate services at a massive national scale.
• Accessibility & Security:
  Conduct rigorous accessibility testing aligned to WCAG 2.2 standards using automated tools (such as axe‑core or Pa11y) and manual screen‑reader testing, while embedding security testing practices (e.g., OWASP Top 10, DAST with OWASP ZAP or Burp Suite) within the delivery pipeline in support of secure‑by‑design principles.
• Shift‑Left Quality:
  Collaborate closely with software engineers, architects, and business analysts to define clear acceptance criteria, review code for testability, and champion shift‑left quality practices.
• Environment & Defect Management:
  Maintain test environments and test data strategies, manage the defect lifecycle, and produce clear quality dashboards and reports for the team and portfolio management.
• Government Service Standards:
  Support formal government service assessments by providing concrete evidence of test coverage, quality metrics, and accessibility compliance.

• Public Sector Delivery:
  Proven experience acting as an SDET or Senior Test Automation Engineer on large‑scale, cloud‑hosted digital or government services.
• Automation Frameworks:
  Deep, hands‑on expertise with modern test automation frameworks such as Selenium, Playwright, Cypress, Cucumber/BDD, Rest Assured, or Karate.
• CI/CD & Cloud:
  Extensive experience integrating automated tests into CI/CD pipelines (e.g., Jenkins, Git Hub Actions) and interpreting pipeline quality gates, alongside experience with AWS‑hosted environments and cloud‑based test execution.
• Performance & API Testing:
  Demonstrable experience in API testing (REST/GraphQL) and executing performance testing at a high‑volume scale.
• Accessibility & Security Compliance:
  Strong knowledge of WCAG 2.2 accessibility…
