About the Role

We are looking for a DevOps & QA Automation Engineer to join our team during a pivotal architectural transformation. You will be directly responsible for building and maintaining robust CI/CD pipelines, integrating automated testing and validation, and driving best practices in release governance and infrastructure automation. As we migrate from a fragmented set of tools to a productised platform, your work will enable high‑confidence deployments, reduce risk, and ensure engineering discipline during rapid change. This is a hands‑on role requiring initiative, attention to detail, and comfort working across build systems, cloud infrastructure, and test environments. This role is best suited to an engineer (3–5 years’ experience) with a strong foundation in DevOps and a genuine interest in embedding quality throughout the software delivery lifecycle.

Key Responsibilities

  • Designing and owning end‑to‑end CI/CD workflows using GitHub Actions
  • Integrating and maintaining test automation into pipelines (unit, integration, system checks)
  • Supporting the engineering team to create unit tests, enforce test coverage, quality gates, and release readiness
  • Implementing environment provisioning, config‑as‑code, and infrastructure automation
  • Working with data and software teams to support secure, reproducible deployments of services and pipelines
  • Collaborating on the re‑architecture initiative by helping define pipeline governance, release controls, and rollout safety mechanisms
  • Supporting the evolution of infrastructure and test‑related standards and documentation
  • Participating in team ceremonies, reviews, and ongoing cross‑functional collaboration

Skills and Experience

  • Prior work in an early‑stage or growth‑stage startup environment
  • 3–5 years’ experience in DevOps, QA automation, or platform engineering
  • Deep experience with CI/CD tooling – ideally GitHub Actions
  • Proficiency in Python, Bash, or Go for automation scripting
  • Experience with infrastructure as code – SAM, AWS CDK
  • Familiarity with test automation frameworks (pytest, unittest, etc.)
  • Understanding of modern software delivery workflows and testing strategies
  • Experience with cloud environments (AWS preferred), including basic IAM, S3, and EC2
  • Knowledge of containerisation and orchestration (Docker, ECS, or Kubernetes)
  • Familiarity with relational databases and test data handling (we use AWS RDS/MySQL)
  • Dashboarding and monitoring with AWS platform and tools
  • A pragmatic, reliability‑focused mindset, with high attention to detail

Nice to Haves

  • Experience embedding quality assurance into pipelines (test coverage enforcement, flaky test detection, etc.)
  • Mobile app automated test technologies, particularly Android Java
  • Familiarity with system monitoring and alerting tooling
  • Exposure to data pipelines or scientific computing environments
  • Previous involvement in platform re‑architecture or CI/CD transformation projects
  • Experience building release governance or audit mechanisms
  • Prior work in an early‑stage or growth‑stage startup environments
