DevSecOps / Platform Engineer
Location: Leeds (Hybrid – 3 days per week in the office)
Salary: £60,000–£90,000 DOE
Tech: AWS, EKS, Terraform, Ansible, GitLab, GuardDuty, CloudTrail
We're looking for two DevSecOps / Platform Engineers to join a growing platform team at an exciting stage of its evolution. Having recently established a dedicated Platform function, the team is now investing in two additional hires to help strengthen cloud security, improve operational resilience, and support the continued migration of critical infrastructure into AWS.
This is an opportunity to join a technology business where you'll have genuine ownership, influence technical direction, and work on modern cloud infrastructure without the bureaucracy often found in larger enterprises.
The Role
You'll work closely with a small, highly collaborative Platform team, helping to build secure, scalable AWS infrastructure while embedding security best practices across the organisation.
The business has recently completed a comprehensive security review with specialist consultants and is now implementing a significant roadmap of improvements. You'll play a key role in delivering these initiatives while supporting day-to-day platform operations and cloud infrastructure.
Projects include:
- Implementing AWS security tooling and best practices
- Supporting the migration of on-premise infrastructure into AWS
- Building and maintaining Infrastructure as Code using Terraform
- Managing Kubernetes workloads running on Amazon EKS
- Automating operational tasks with Ansible
- Working alongside external security consultants to triage and respond to platform and security alerts
- Rolling out new security technologies including GuardDuty, CloudTrail, Panther, SentinelOne, Tailscale and modern endpoint management solutions
- Contributing to platform reliability, monitoring and operational improvements
- Supporting event-driven architecture and messaging infrastructure
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Tech Environment:
- AWS
- Amazon EKS (Kubernetes)
- Terraform
- Ansible
- GitLab CI/CD (Jenkins experience also considered)
- GuardDuty
- CloudTrail
- Tailscale
Experience with FinOps, cloud cost optimisation or cloud security tooling would be advantageous but isn't essential.
About You
We're interested in engineers who enjoy taking ownership and solving problems rather than waiting to be directed.

You'll ideally have:
- Commercial experience with AWS infrastructure
- Experience working with Terraform
- Exposure to Kubernetes, ideally Amazon EKS
- Knowledge of DevSecOps or cloud security principles
- Experience automating infrastructure with Ansible
- An understanding of CI/CD pipelines
- Strong troubleshooting skills and a proactive approach to problem solving

Who We're Looking For
The team is hiring at multiple levels.
For more junior candidates, we're looking for around two or more years of commercial experience alongside a strong academic background.
For more experienced engineers, you'll bring proven production experience across AWS platform engineering and cloud security, with the ability to help shape best practices within a growing team.
Candidates from startup, scale-up or smaller consultancy environments are likely to thrive. We're particularly interested in engineers who enjoy being hands-on and taking responsibility, rather than those coming from highly siloed enterprise environments.
Interview Process
Stage 1: Video interview with the hiring managers
Stage 2: On-site interview in Leeds (approximately 90 minutes), including technical discussion, practical exercises and the opportunity to meet the wider team
Final Stage: Meeting with the Managing Director
If you're looking for a role where you'll have genuine ownership, work with modern AWS technologies, and help shape the future of a growing Platform function, we'd love to hear from you.
