• Designing highly resilient, scalable and secure distributed cloud systems.
• Maintaining complex, modular Infrastructure as Code using technologies such as Terraform, AWS CDK or Pulumi.
• Architecting internal developer platforms and enterprise-grade CI/CD frameworks that enable engineering teams to operate autonomously and securely.
• Evaluating emerging AWS services and third-party technologies to identify opportunities to strengthen the technology stack and reduce time-to-market.
• Driving AWS cost optimisation initiatives and identifying opportunities to improve cloud efficiency.
• Resolving systemic performance bottlenecks across microservices, databases and network layers.
• Working cross-functionally to ensure cloud infrastructure integrates effectively with wider product development.
• Mentoring Senior, Mid-Level and Junior Engineers and supporting the continued development of cloud engineering capability across the organisation.

About You

You’ll be an experienced AWS Cloud Engineer with extensive experience designing and delivering complex cloud infrastructure at scale.

You’ll also have:

• Extensive professional experience working specifically with AWS cloud infrastructure.
• Expert knowledge of the wider AWS ecosystem, including complex networking technologies such as Transit Gateway and Direct Connect.
• Strong knowledge across AWS compute, data storage, networking and enterprise security configurations.
• Exceptional proficiency in Infrastructure as Code and configuration management.
• Strong software engineering experience with deep expertise in at least one modern programming language, such as Python, Go, Java or Node.js.
• Proven experience designing, deploying and maintaining large-scale distributed systems and microservices architectures.
• Demonstrable experience leading significant technical projects and influencing technical decision-making across multiple teams.
• The ability to build consensus across engineering teams and contribute to wider engineering culture and best practice.
• Strong communication skills with the ability to operate as a trusted technical advisor to engineering leadership.
• A minimum of AWS Associate certification or higher.

Why Apply?

This is an excellent opportunity to take on a highly influential technical position within an organisation delivering complex technology across defence, security and innovation.

In return, you’ll benefit from:

• Salary of up to £100,000, dependent on experience.
• Competitive benefits package.
• Permanent, full-time position.
• Hybrid working across Bristol, Malvern or Farnborough.
• The opportunity to shape cloud architecture and engineering strategy at a senior level.
• Exposure to complex, large-scale AWS environments and cutting-edge technologies.
