Job description

We are seeking a highly skilled and experienced DevOps Engineer with strong AWS expertise to join our client project team. This role will focus initially on developer enablement and CI / CD pipeline optimisation, and then evolve into broader infrastructure automation and operations as the platform matures. The ideal candidate will bring hands‑on AWS experience, automation‑first thinking, and a passion for enabling development teams through reliable, scalable, and observable infrastructure.

What you'll do :

  • Assess the current pipeline and infrastructure setup; recommend and implement improvements aligned with industry best practices.
  • Design, implement, and maintain CI / CD pipelines using AWS‑native services (CodePipeline, CodeBuild, CodeDeploy, ECR).
  • Build and manage infrastructure as code (Terraform, CloudFormation, AWS CDK) and increase IaC maturity across the environment.
  • Automate deployments, provisioning, monitoring, and incident response processes.
  • Enable developer productivity by reducing deployment friction, providing templates, scripts, and self‑service tooling.
  • Design, develop, test, and deploy serverless applications (AWS Lambda) and containerised workloads (ECS / Fargate).
  • Improve observability using monitoring and logging tools (CloudWatch, X‑Ray, ELK stack).
  • Work with microservices architecture (Aurora Postgres backend, ECS containers, modular reusable services).
  • Provide guidance and mentorship to junior team members.

Your Expertise :

  • Strong practical AWS experience (S3, ECS / Fargate, RDS / Aurora, ECR, IAM, Redis, VPC, Parameter Store / Secrets Manager, WAF).
  • Solid knowledge of containerisation technologies (Docker, ECS; Kubernetes experience beneficial though not in current use).
  • Proficiency in Infrastructure as Code (Terraform, CloudFormation, AWS CDK).
  • Strong scripting in Python, Bash, or similar.
  • Experience designing / building CI / CD pipelines and automating infrastructure from scratch.
  • Familiarity with Java / Tomcat applications (bonus).
  • Hands‑on experience with monitoring / observability (CloudWatch, ELK, X‑Ray).
  • Experience with SQL / NoSQL databases.
  • Strong problem‑solving skills and ability to stabilise infrastructure under scale.
  • AWS Certification (Solutions Architect, DevOps Engineer, or similar).
  • 3–5 years' experience implementing AWS automation pipelines.
  • Familiarity with Step Functions, certificate automation.

    • Attributes :

  • Tenacious and results‑driven with the ability to build and manage infrastructure from scratch.
  • Data‑driven engineering mindset.
  • Strong communicator to both technical and non‑technical audiences.
  • Self‑motivated, collaborative, and able to mentor others.
