Platform Engineer

Platform Engineer Create Pay Milton Keynes, MIK, gb

This is a remote position.

Create Pay is building its Payment Facilitator (Pay Fac)/Acquiring platform on AWS and is building a dedicated platform engineering capability from the ground up. We are looking for a hands‑on Platform Engineer to build and own the infrastructure the platform runs on, day to day. This is the first dedicated platform hire at Create Pay — the role is deliberately pitched for someone looking to build their own path into platform/infrastructure engineering, rather than an established platform lead looking to manage an existing team or programme.

You will take practical, day-to-day ownership of Create Pay's cloud infrastructure: provisioning and hardening AWS environments, building and maintaining CI/CD pipelines, keeping the serverless and data estate — API Gateway, Lambda, Aurora PostgreSQL — reliable, observable, and cost‑efficient, and acting as first responder when something breaks. You will work closely with Engineering, Data Engineering, the Information Security Officer, and outsourced delivery partners to make sure the platform is resilient by design, not patched together after the fact.

This is a genuine opportunity to define a discipline — to own the infrastructure behind a real, regulated, in‑production payments environment, set the practices and standards it runs on, and grow the role, and yourself, as Create Pay scales.

We are looking for a self‑starter with roughly 2–5 years' hands‑on platform, infrastructure, or Dev Ops experience (junior to mid‑level) who wants to specialise and grow into an in‑house platform engineering career, rather than someone already operating at head‑of‑platform level. You should be comfortable with core AWS infrastructure tooling — infrastructure as code (Terraform, Cloud Formation, or CDK), CI/CD pipelines, API Gateway, Lambda, and Aurora PostgreSQL — and confident applying fundamentals such as high availability, fault tolerance, observability, and cost control in a live environment.

Payments or fintech exposure is an advantage but not required; what matters more is a practical, first‑principles approach to infrastructure, and the ability to explain what you're doing and why in plain terms to engineers and the wider business alike. We value people who implement pragmatic, well‑understood patterns over those who lean on theory, jargon, or unnecessary complexity. A platform you've built and kept running, or an incident you've resolved and can clearly explain, will count for far more than a stack of certifications.

• Provision, configure, and harden AWS environments — networking, compute, and storage — using infrastructure as code
• Maintain clear separation and consistent configuration across development, staging, and production environments
• Own capacity planning and cost management across the AWS estate

• Build and maintain CI/CD pipelines that let Engineering (Internal and Partners) ship safely and frequently
• Implement automated testing, deployment, and rollback processes
• Support deployment of AI generated applications and tooling
• Support change control and release management alongside Engineering and the Information Security Officer

• Design and maintain systems for high availability, fault tolerance, and resilience by default
• Implement logging, monitoring, and alerting (for example Cloud Watch) across services and infrastructure
• Maintain data pipelines, backup, and lifecycle management for Aurora PostgreSQL and other AWS‑native data tooling

• Act as first responder for infrastructure incidents, supporting root cause analysis and post‑incident review
• Coordinate patching, upgrades, and lifecycle management across the AWS estate
• Support ICT disaster recovery testing and business continuity exercises

• AWS (primary platform) — VPC, IAM, Lambda, ECS/Fargate, API Gateway, Aurora PostgreSQL
• Infrastructure as code — Terraform, Cloud Formation, or AWS CDK
• CI/CD tooling — for example Git Hub Actions, AWS Code Pipeline/Code Build
• Observability — Cloud…
