Join an award-winning B2B consultancy at the forefront of enterprise AI, building and owning the cloud-native platform infrastructure that powers production-grade conversational and generative AI products at scale.

The role

This is a platform and infrastructure engineering role - not a data science or ML engineering position. You'll own the runtime, infrastructure, and operational layers that RAG pipelines, LLM orchestration, vector search, and evaluation workflows run on, across AWS and Databricks. The focus is on building scalable, observable, secure, and cost-efficient platform infrastructure that enables AI engineering teams to ship and operate AI products reliably in production.

What you'll do

  • Design, build, and operate cloud-native AI platform infrastructure across AWS (Lambda, API Gateway, DynamoDB, S3, CloudWatch) and Databricks
  • Deploy and operate containerised services on Kubernetes using Terraform for infrastructure-as-code
  • Own and scale vector search infrastructure (OpenSearch, Algolia, AWS Bedrock Knowledge Bases) and embedding pipelines
  • Build and maintain CI/CD pipelines for inference services, retrievers, ingestion workflows, and RAG components
  • Implement observability across AI workloads using CloudWatch, MLflow, and OpenTelemetry - covering latency, throughput, cost, and system health
  • Apply secure-by-design principles including IAM, encryption, network controls, and audit logging
  • Work closely with AI engineers to translate prototypes and proof-of-concepts into production-ready, well-architected platform components

What we're looking for

  • Proven experience in platform, infrastructure, or software engineering roles delivering production-grade systems on AWS
  • Strong hands-on Kubernetes experience, specifically with EKS (Elastic Kubernetes Service) and ECS (Elastic Container Service) in production environments
  • Strong Terraform experience for infrastructure-as-code, provisioning and managing cloud infrastructure at scale
  • Experience operating containerised services, managing CI/CD pipelines, and owning observability and reliability
  • Familiarity with vector databases or search infrastructure (OpenSearch, Algolia) is a strong advantage
  • Python proficiency for scripting, automation, and deploying production services
  • Solid grasp of distributed systems, cloud-native architecture, microservices, and API design
  • Ownership mindset - comfortable operating autonomously across reliability, performance, cost, and security

Why join? You'll own the foundational platform infrastructure behind a growing suite of generative AI products, working directly with senior AI and engineering leaders. This is a deep technical ownership role with long-term architectural impact, within an organisation investing heavily in AI at scale.

Where to Advertise Cyber Security Jobs in the UK (2026 Guide)

Where to advertise cyber security jobs UK in 2026: the specialist boards, communities and channels that reach offensive, defensive and GRC security talent. The candidate pool is small, heavily vetted and in high demand across government, financial services, critical national infrastructure and the private sector simultaneously. Many of the strongest candidates hold active security clearances, are not actively job-searching through general platforms, and move primarily through specialist networks and trusted referrals. General job boards reach a broad audience but lack the specificity that security professionals expect. Specialist platforms, government-affiliated channels and cleared candidate networks each serve a different part of the market. This guide, published by CybersecurityJobs.tech, covers where to advertise cyber security roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Cyber Security Jobs UK 2026: What to Expect Over the Next 3 Years

Cyber Security Jobs UK 2026: roles, salaries and the threat intelligence, cloud security and zero-trust hiring trends shaping UK cyber careers. Cyber security is one of the few sectors where demand for talent has never once dipped. Every major technological shift of the past decade — cloud migration, remote working, AI adoption, the proliferation of connected devices — has expanded the attack surface that security professionals are expected to defend. And every expansion of that attack surface has generated more jobs. But the cyber security jobs market of 2026 is not simply a larger version of what it was three years ago. It is a structurally different market. The threats have evolved, the technologies used to combat them have changed, the regulatory environment has tightened considerably, and the roles being created reflect all of that. A job seeker who understands only the cyber security landscape of 2023 is already working with an outdated map. The candidates who will thrive over the next three years are those who understand where the sector is heading — which specialisms are attracting the most investment, which technologies are reshaping defensive and offensive security practice, and how the definition of a cyber security professional is broadening well beyond the traditional image of a network defender in a SOC. This article breaks down what the UK cyber security jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career ahead of the curve.
