About the role
As a primarily AWS-focused Platform Engineer at Naimuri, you’ll be hands‑on in designing, building, and supporting secure, scalable, and automated cloud infrastructure using Amazon Web Services. You’ll operate at the intersection of platform engineering and cloud architecture‑enabling teams to move faster, deploy with confidence, and embrace modern DevSecOps practices. You’ll work in a cross‑functional platform capability, collaborating with developers, data, and delivery leads to turn infrastructure into reusable, self‑service products. We operate in different cloud environments, so the opportunity to cross‑skill in platforms such as Azure and Google Cloud will also be available.
Responsibilities
* Build & Automate: Deliver reusable infrastructure modules and CI/CD pipelines using GitLab or AWS CodePipeline/CodeBuild to support consistent and secure deployments.
* Platform Ownership: Contribute to the development and refinement of internal AWS Landing Zones, ensuring secure‑by‑default and policy‑driven environments across multiple accounts.
* Operational Excellence: Monitor, troubleshoot, and continuously improve environments using tools like CloudWatch, CloudTrail, and GuardDuty.
* Governance & Policy: Implement and maintain IAM roles and policies, Service Control Policies, tagging strategies, and cost‑control measures.
* Security First: Embed secure design principles into everything you build; support identity and access management, Secrets Manager/KMS integration, secure pipelines and vulnerability management.
* Collaboration & Enablement: Work with delivery teams to support their use of the platform, coach on best practices, and help define golden paths and documentation that lower the barrier to adoption.
* Innovation & Evolution: Stay up to date with AWS capabilities, contribute to capability assessments, and actively suggest improvements or new services that align with company strategy (e.g., enabling AI/ML or hybrid connectivity).
Location & Working Arrangements
The role is based in, or around the area of Portsmouth. The role would be hybrid working where you can work from home for part of your working week with time on site being based on the needs of your assigned delivery and agreed Ways of Working for your team. On‑site location would be in Portsmouth primarily, and would normally be a maximum of one or two days per week based on specific delivery demand but you would be welcome to spend more days in the office if you preferred. There would be occasional travel to Manchester estimated to be no more than once or twice a year.
Qualifications
* 3+ years hands‑on experience with AWS cloud environments in production.
* Strong experience with IaC (Terraform, CloudFormation, CDK).
* CI/CD tooling (GitLab, Argo, AWS CodePipeline/CodeBuild).
* AWS Networking (VPCs, PrivateLink, Security Groups, Route Tables, Transit Gateway, etc.).
* Identity & Access Management (IAM, Organizations, SSO).
* Monitoring & Security (CloudWatch, GuardDuty, Config, Security Hub).
* Container Orchestration (Kubernetes, RedHat Openshift, Helm, Kustomize, Docker/Podman).
* Experience building and consuming shared infrastructure as code modules in a GitOps‑style setup.
* Ability to troubleshoot cloud‑native, micro‑service applications, networking, and infrastructure issues.
* Exposure to AWS data and AI/ML services (SageMaker, Comprehend, Rekognition, Bedrock, etc.) is desirable.
Desirable / Bonus
* Exposure to hybrid cloud setups (e.g., on‑prem integration or restricted networks).
* Familiarity with supporting data/AI pipelines or platform integrations (Glue, SageMaker, Step Functions, EventBridge).
* Awareness of enterprise controls (NCSC/Cyber Essentials, NIST, or similar frameworks).
* Understanding of cloud cost optimisation and FinOps practices.
* Exposure to other cloud environments (Azure, Google Cloud).
Behaviours
* Proactive problem‑solver who balances pragmatism with long‑term maintainability.
* Comfortable owning delivery, making trade‑offs, and asking the “so what?”.
* Collaborative, with good communication skills and a bias toward enabling others.
* Security‑conscious and compliance‑aware without being a blocker.
* Willing to continuously learn and adapt to new challenges.
