AWS Platform Engineer in London

Join Microlise as an AWS Platform Engineer on a 12-month fixed term contract and help build the cloud platform that will power the next generation of analytics, AI and digital services. This is a rare opportunity to shape a strategic AWS platform from the ground up, establishing the engineering foundations, automation, security controls and operational standards that future teams will build upon.

Working within our Platform Engineering team, you'll design and implement reusable AWS capabilities that enable engineers across Microlise to deploy securely, operate confidently and innovate at scale.

What will you be doing?

• Build the foundations for our AWS future. Microlise is making a significant investment in its next-generation cloud platform, creating the foundations for advanced analytics, AI-driven products, data services and future digital innovation.
• The platform you build won't just support one application or project. You'll help create reusable capabilities, standards and deployment patterns that can be adopted across future AWS workloads.
• Your first focus will be helping establish the production-ready AWS foundations needed by our Analytics and AI programme, while creating reusable platform capabilities for future workloads.
• Build and automate AWS infrastructure using Terraform and Infrastructure as Code.
• Establish reusable infrastructure modules, deployment patterns and engineering guardrails.
• Build and improve CI/CD pipelines for infrastructure and platform services.
• Implement AWS security controls, IAM patterns, secrets management and secure networking.
• Establish monitoring, logging, alerting and operational observability across the platform.
• Implement tagging, cost visibility, budgets and FinOps controls to help teams understand and manage cloud consumption.
• Work closely with architecture, security, data engineering and development teams to create a platform that is secure, reliable and straightforward to consume.

Build, shape and scale a modern AWS platform.

• Design, build and operate secure, resilient AWS infrastructure and shared platform services.
• Develop reusable modules and automation that allow teams to provision infrastructure consistently.
• Build deployment pipelines and automated controls that make infrastructure changes safe, repeatable and auditable.
• Implement cloud networking patterns including VPCs, routing, DNS, security groups and connectivity between AWS and existing environments.
• Embed security by design, including least-privilege access, encryption, secrets management, vulnerability management and policy enforcement.
• Build platform observability using metrics, logs, traces, dashboards and automated alerting.
• Establish backup, recovery, resilience and operational readiness patterns.
• Implement cloud cost management through tagging standards, budgets, monitoring, optimisation and FinOps practices.
• Support multi-account and multi-environment AWS architectures with appropriate governance and controls.
• Create platform documentation, engineering standards and reusable patterns that make it easier for development teams to adopt AWS.
• Collaborate closely with Architecture, Security, Data Engineering, AI Engineering and application teams to continually improve the developer experience.

Create a platform that accelerates engineering.

This role isn't just about keeping infrastructure running. We want to create a platform that allows engineering teams to move faster without compromising security, reliability or cost control. You'll help establish the paved roads that enable teams to deploy workloads without needing to reinvent infrastructure, networking, monitoring or security for every project.

What are we looking for?

• Strong hands-on experience building and operating infrastructure on AWS.
• Strong Infrastructure as Code experience, including reusable modules and automated deployment.
• Good understanding of AWS networking, including VPCs, subnets, routing, DNS, security groups and hybrid connectivity.
• Strong understanding of AWS IAM, security controls, encryption, secrets management and least-privilege access.
• Experience implementing cloud monitoring, logging, alerting and observability.
• Experience working with multi-account AWS environments, governance and environment separation.
• Comfortable scripting and automating using Python, Bash, PowerShell or similar.
• Good understanding of cloud resilience, backup, disaster recovery and operational support.
• A collaborative, ownership-led mindset and the confidence to work with engineers, architects, security teams and other technical stakeholders.

Help define how AWS engineering works at Microlise.

You'll have the opportunity to help shape our engineering standards, automation, tooling and ways of working as the AWS platform develops. We're looking for engineers who enjoy that environment: people who can take an architectural direction, turn it into working engineering capability and leave behind something that is automated, documented and easier for the next team to use. Don't worry if you don't tick every box; we're keen to hear from candidates who are eager to learn and develop!
