Job description

Job Title: Naimuri - AWS Platform Engineer

Location: Portsmouth, England, United Kingdom

Job ID: 19270

We can offer you the chance to help make the UK a safer place through innovation, working in partnership with government and law enforcement organisations on some of the most challenging data and technology problems out there.

We strongly encourage candidates of all different backgrounds and identities to apply. We are committed to building an inclusive, safe and supportive environment that allows everyone to do their best work. We are happy to support any accessibility or neurodiversity requirements that you may need during the recruitment process.

About us:

We’ve been around for about ten years and grown from being a little-known tech start‑up to creating our own community at the heart of the thriving and diverse tech and digital ecosystem of Greater Manchester. As part of our future journey we’re looking to create footprints in other areas of the UK, and in this instance around the Portsmouth and Salisbury Plains area.

Our name Naimuri is Japanese and simply means… ‘nai’ meaning ‘not’ ‘muri’ meaning ‘overburden’.

These principles apply to every aspect of an organisation from technology, process and infrastructure, through to people, culture and leadership. This means that we empower our teams to do what they think is the right thing, giving them the skills and confidence to explore new ways of working, and to create a bias‑free environment, where all our people feel comfortable collaborating to deliver the finest ideas and solutions in an agile environment.

Our business is focused on 4 cornerstones, which shape and underpin the way in which we go about work and treat each other. These are: Wellbeing, Empowerment, Perpetual Edge and Delivery.

People and culture are at the heart of Naimuri, so that collectively, we can realise our mission of ‘making the UK a safer place to be’.

Overview:

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.

You're expected to have solid practical AWS experience, curiosity about how things work at scale, and an instinct for automation, governance, and cloud‑native thinking.

Key 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, whilst expanding your knowledge into the AWS workspace.
• 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).

Core Skills & Experience:

3+ years hands‑on experience with AWS cloud environments in production.

Strong experience with:

• IaC (Terraform, CloudFormation, CDK)
• AWS Networking (VPCs, PrivateLink, Security Groups, Route Tables, Transit Gateway, etc.)
• Identity & Access Management (IAM, Organizations, SSO)
• Monitoring & Security (CloudWatch, GuardDuty, Config, Security Hub)

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.

While this is primarily a cloud engineering role, we’re especially interested in candidates with exposure to AWS data and AI/ML services (such as SageMaker, Comprehend, Rekognition, Bedrock, or related tooling).

• Exposure to hybrid cloud setups (e.g., on‑prem integration or restricted networks)
• Familiarity with supporting data/AI pipelines or platform integrations (e.g., 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

Location:

Whilst our Head Office is based in Salford Quays, Manchester, with satellite offices in London and Cheltenham, the location for this role is 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. Onsite 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.

Pay and benefits:

A full‑time working week is 37.5 hours and you have flexibility over when you give that time. We also offer part‑time working which can be discussed during the recruitment process.

>Our core hours are 10:00am - 3:00pm and our office hours are between 7:30 and 18:00 Monday to Friday.

Benefits include:

• Flexible/Hybrid working options
• A company performance related bonus
• Pension matched 1.5x up to 10.5%
• AXA group 1 medical cover
• Holiday buy‑back sc

Recruitment Process:

We want to ensure that you feel comfortable and confident when interviewing with us. To help you prepare, our recruitment team will discuss the process in more detail with you when you apply.

We are happy to support any accessibility or neurodiversity requirements.
