Senior Platform Engineer

We are seeking a Senior Platform Engineer to join a forward-thinking financial services organisation embarking on a greenfield platform build. This is a unique opportunity to shape the foundation of a next-generation infrastructure in a highly regulated environment, leveraging cloud, automation, and AI technologies.

You will play a key hands-on role in designing, building, and maintaining a scalable, secure, and high-performing platform built on AWS, Linux, and Kubernetes. Ideal candidates will bring a development or scripting mindset, with the ability to automate infrastructure, streamline operations, and contribute to architectural decisions.

This is a full hands-on engineering position, offering significant influence over technology choices and the opportunity to introduce AI / LLM integrations into the platform as it evolves.

Key Responsibilities

  • Design, build, and manage a secure, scalable platform environment in AWS.
  • Implement and maintain container orchestration using Kubernetes.
  • Develop automation tooling, scripts, and infrastructure-as-code solutions (Python, Terraform, etc.).
  • Collaborate with cross-functional teams to design solutions aligned with business and regulatory requirements.
  • Apply strong networking knowledge to optimise performance, security, and reliability.
  • Ensure compliance with financial services regulations and internal security policies.
  • Contribute to CI/CD pipelines and cloud-native observability solutions.
  • Explore and integrate emerging technologies including AI / LLM-based solutions to enhance automation and operational efficiency.

Key Skills & Experience

Essential:

  • Strong hands-on experience with AWS (EC2, VPC, IAM, S3, ECS/EKS, etc.)
  • Solid understanding of Linux systems administration and troubleshooting
  • Expertise with Kubernetes (deployment, scaling, networking, monitoring)
  • Proficiency in Python for scripting, automation, or tooling development
  • Good understanding of networking principles (TCP/IP, DNS, load balancing, firewalls)
  • Background in DevOps, Platform Engineering, or Infrastructure as Code (IaC) environments
  • Strong awareness of security, compliance, and resilience in financial or regulated sectors

Desirable:

  • Experience introducing or working with AI / LLM solutions
  • Familiarity with Terraform, Ansible, GitLab CI/CD, or similar tools
  • Exposure to financial services or other highly regulated industries
  • Experience with observability stacks (Prometheus, Grafana, ELK, etc.)
