AWS Cloud Infrastructure Engineer

We are looking for a battle-tested AWS Cloud Infrastructure Engineer to join a dynamic team that is driving the transformation of an established, on-prem leader into a cutting-edge cloud-first business.

You’ll be instrumental in optimising and scaling the cloud infrastructure, ensuring its financial efficiency, and leading the charge on cloud observability.

With a strong backing from leadership, you'll help drive best practices, improve performance metrics, and lay the foundation for the future growth of the cloud division.

Key Responsibilities

  • Design and refine AWS cloud environments to ensure seamless performance and effortless scaling as business demands grow.
  • Evaluate and enhance cloud infrastructure to efficiently support 1,000-1,500 users while maintaining optimal performance.
  • Utilise Infrastructure as Code tools like AWS CloudFormation or Terraform to automate and standardise deployments.
  • Control cloud spending by applying AWS FinOps principles, identifying inefficiencies, and optimising cost structures.
  • Monitor and analyse cloud environments using tools like Datadog or other observability platforms to preempt issues before they impact users.
  • Strengthen security and resilience by proactively refining disaster recovery strategies, monitoring performance metrics, and enforcing best-in-class security frameworks.
  • Develop scalable, efficient, and cost-effective cloud solutions while documenting processes to ensure smooth operations.
  • Engage with enterprise clients and stakeholders to ensure cloud infrastructure meets stringent security, performance, and compliance standards.
  • Push the boundaries of innovation by challenging current methods and introducing AWS best practices—all while ensuring minimal disruption to ongoing operations.
  • Mentor and upskill team members in cloud, automation, and security best practices.

Tech Stack & Tools

  • Cloud: AWS (EC2, S3, Lambda, RDS, IAM, etc.)
  • Infrastructure as Code: Terraform or CloudFormation
  • Observability & Monitoring: Datadog or similar tools
  • Cost Optimisation & FinOps: AWS native tools or third-party solutions
  • Security & Compliance: AWS security best practices and governance

Ideal Candidate Profile

  • Proven AWS experience in a similar SaaS, healthcare, retail, or corporate environment.
  • Strong understanding of cloud cost management (FinOps).
  • Experience in designing scalable cloud architecture and optimizing infrastructure.
  • Ability to navigate complex team dynamics, deal with pushback, and influence change.
  • Hands-on approach with battle scars to prove it—this is not a theoretical role.
  • Experience working across global teams & time zones (Eastern Europe a plus).
  • Solid grasp of AWS security, DR planning, and cloud financial governance.

Why You Should Apply

  • Be at the forefront of a major cloud transformation from on-prem to AWS.
  • Opportunity to shape cloud strategy and have full backing to implement changes.

This is more than just a BAU role—it is an opportunity to make a real impact. If you have a passion for problem-solving and a drive to thrive hit the apply button!
