Senior SRE / DevOps Engineer - Contract - Inside IR35 (Hiring Immediately)

We are looking for a senior SRE / DevOps practitioner to design, standardise, and operate  cloud platforms that support multiple AI-driven products and services . This role focuses on building  opinionated, reusable infrastructure patterns  that enable teams to rapidly deliver AI workloads while maintaining high standards for reliability, security, and cost control.

You will develop  platform architecture across multiple concurrent projects , ensuring consistency in how services are deployed, integrated, and operated. This includes shaping how workloads are built, deployed, and monitored, as well as defining clear patterns for service communication, API exposure, and infrastructure provisioning.

This is a hands-on role for someone who is comfortable making  strong architectural decisions , reducing variability across teams, and balancing flexibility with standardisation in a fast-moving environment.

Requirements

Platform Architecture & Standardisation

• Define and implement  opinionated architecture patterns  for cloud-native and AI-enabled services on AWS
• Establish reusable blueprints for these same services
• Drive consistency across multiple projects through shared modules, templates, and platform tooling

Infrastructure as Code & Automation

• Build and maintain  Terraform-based infrastructure , using modular and reusable design
• Define CI/CD patterns for:
• infrastructure deployment
• application and model delivery
• Enforce best practices through pipelines and automation rather than documentation

Reliability, Observability & Operations

• Embed SRE principles across all services:
• monitoring, logging, tracing
• SLIs/SLOs and alerting
• Continuously improve reliability, performance, and cost efficiency
• Operate API gateway/data plane technologies (e.g. Kong)

Required Skills & Experience

• Strong experience operating  AWS-based platforms in production
• Proven experience with  Terraform , including module design and CI/CD integration
• Hands-on experience with  container platforms (ECS preferred; EKS acceptable if adaptable)
• Experience operating  API gateways  (Kong or equivalent)
• Solid understanding of  cloud networking and service discovery patterns
• Experience supporting  multiple teams or projects on a shared platform
• Strong troubleshooting and production operations experience

AI / Data Platform Experience (Required)

• Practical experience running or supporting  AI/ML workloads in production , such as:
• model inference services
• batch processing pipelines
• integration with LLM APIs or hosted models

• Understanding of:
• scaling characteristics of AI workloads
• cost considerations (compute-heavy workloads, GPU usage, etc.)

• Familiarity with tooling such as:
• model serving frameworks
• data processing pipelines
• or managed AI services on AWS
