Job description
About the Position
We are seeking a DevOps Engineer to lead the scaling, optimisation, and management of our cloud infrastructure behind media-scale, high-traffic web applications. In this role, you will manage robust containerised systems on AWS ECS, own our CI/CD and deployment orchestration, and drive our architectural evolution - ensuring high availability and predictable performance under heavy production traffic. AI/ML workloads are a growing part of the picture, and you will help shape how that side of the infrastructure develops. You will collaborate closely with cross-functional teams to build automation-first solutions that align with our engineering standards.
Responsibilities
Cloud Infrastructure and Automation
- Manage, optimise, and scale cloud infrastructure on AWS using infrastructure-as-code methodologies (Terraform).
- Design, deploy, and maintain secure containerised environments on AWS ECS that scale dynamically with application demand.
- Automate complex operational tasks through scripting to minimise manual overhead and enhance system reliability.
CI/CD and Deployment Orchestration
- Build and refine CI/CD pipelines in GitHub Actions, including reusable workflow design and OIDC-based authentication to AWS.
- Maintain and extend our custom deployment orchestration tooling.
- Deploy and operate serverless components - Lambda functions and Lambda container images - via the Serverless Framework.
Edge, CDN, and Traffic Management
- Manage Cloudflare (CDN, DNS, WAF, VPN tunnels) as code through Terraform.
- Operate Fastly in front of the web application and support multi-CDN traffic management.
Reliability, Observability, and Performance
- Own observability in Datadog - APM, RUM, Synthetics smoke tests, and monitors-as-code.
- Monitor system health, application performance, and concurrency metrics to guarantee high availability during peak traffic periods.
- Identify risks in infrastructure and deployment reliability early, and act before they escalate.
Requirements
- 3+ years of professional experience in DevOps or CloudOps roles.
- Experience deploying and managing cloud infrastructure for media-scale, high-traffic web applications. Familiarity with AI/ML services is a plus as we grow AI usage.
- Hands-on production experience with Terraform and infrastructure-as-code workflows.
- Hands-on production experience with GitHub Actions, including reusable workflow design and OIDC-based authentication. Experience building or maintaining custom deployment orchestration tooling is a plus.
- Proficiency in Python and Bash scripting for infrastructure automation.
- Strong understanding of containerisation technologies, including Docker and AWS ECS, along with networking fundamentals.
- Experience with Cloudflare (CDN, DNS, WAF) and/or Fastly for multi-CDN traffic management.
- Familiarity with Datadog for APM, monitoring-as-code, and synthetic testing.
Nice to Have
- Experience with AWS AI/ML services or infrastructure for LLM-facing applications.
- Experience with Kubernetes (EKS), Helm charts, and cluster autoscaling mechanisms - useful, but not used day to day on the current stack.
- Familiarity with GraphQL APIs, OpenAPI standards, and authentication protocols including OAuth and SAML.
We Offer
- Competitive full-time compensation and high operational autonomy.
- Clear growth opportunities across modern cloud, edge, and AI infrastructure projects.
- Remote-first working environment with flexible scheduling.
- A company culture built on transparency, continuous learning, and absolute ownership.
About the Company
Since 2006, Speed & Function has delivered state-of-the-art technical solutions through a partnership-first model. We operate as a Deliberately Developmental Organisation, focusing intensely on the intersection of human potential and technological innovation.
Why this is Worth Your Time
You will have real ownership over how our infrastructure is architected and how it evolves - from cloud foundations and CDN edge configuration to the CI/CD and deployment orchestration that ships everything. Your decisions on IaC, pipeline design, and container orchestration will directly shape how reliably our systems run under real production traffic.
The current focus includes high-traffic media platforms and a growing AI footprint, and the scope will keep expanding as we take on new projects. It is a place for someone who wants high autonomy, variety in what they build and operate, and the chance to keep deepening their expertise across modern cloud and infrastructure practices.
