The opportunity
We're looking for a passionate, cloud-focused Senior DevOps / DevSecOps Engineer to build, automate, and secure cloud infrastructure. You'll own infrastructure-as-code, strengthen security posture across the pipeline, and help shape solid AWS foundations aligned with the AWS Well-Architected Framework and cloud best practices. A key part of this role is the ability to analyze existing infrastructure and propose meaningful improvements - in security, reliability, cost, and automation. This is a hands-on engineering role for someone who genuinely loves the cloud and wants to make automation and security first-class citizens of how we work.
Your key responsibilities

- Apply the AWS Well-Architected Framework and AWS best practices across our environments
- Analyze existing infrastructure and propose improvements across security, scalability, resilience, performance, and cost
- Embed security into every stage of the delivery lifecycle (DevSecOps): automated security checks, least-privilege IAM, secrets management, and continuous compliance
- Build and improve CI/CD pipelines for reliable, repeatable, automated delivery
- Support cloud migration efforts (lift-and-shift, re-platform, modernization)
- Manage IaC workflows and governance (Terraform state, modules, policy-as-code)
- Monitor, troubleshoot, and continuously improve cloud environments
- Collaborate with development, security, and platform teams to drive best practices
Skills and attributes for success
- 5-6+ years of professional experience in DevOps / cloud / platform engineering
- Strong, primarily AWS -focused hands-on experience, with familiarity across the most common AWS services (compute, networking, IAM, storage, monitoring, databases)
- Experience applying the AWS Well-Architected Framework and AWS best practices
- Experience building AWS foundations and working with AWS Organizations (multi-account, guardrails, governance)
- Proven Infrastructure as Code experience - Terraform preferred (this is a core requirement)
- Hands-on cloud migration experience
- Ability to analyze existing environments and recommend practical improvements
- A genuine passion for cloud technology and continuous learning
- Strong CI/CD and automation fundamentals
Ideally you`ll also
- Bring cross-cloud experience (Azure and/or GCP) - a definite plus
- Hold AWS certifications: DevOps Engineer, Solutions Architect, or any AWS Specialty
- Demonstrate experience with Spacelift (or similar IaC orchestration/management platforms)
- Apply policy-as-code, security scanning, and compliance tooling experience
- Leverage containerization and orchestration experience (Docker, Kubernetes/EKS)
