Job description

Location: Bristol/Cirencester (1 day a week in the office)

Reporting to: Head Of Infrastructure

Kallidus is a leading SaaS provider of learning, performance, and talent management solutions. Our award-winning platform helps hundreds of organisations worldwide empower their people to perform at their best — from simplifying compliance to driving skills development and measurable business outcomes.

We are a technology company, not just a company that "does technology". We build it ourselves, we own it entirely, and the people who lead that work have real influence over how it evolves. Come build, grow and make a difference!

The Role

We are looking for an experienced Senior DevOps Engineer to join our team and help manage, automate and continuously improve the platforms that underpin our applications and services.

Working closely with Infrastructure and Development teams, you will be responsible for ensuring our platforms are secure, resilient, scalable and operationally effective. You will drive automation, improve platform reliability and support the efficient delivery of services into production.

You will play a key role in managing and evolving our cloud infrastructure, CI/CD tooling, Infrastructure as Code and container platforms, helping to define platform standards and best practices across the organisation.

We are looking for someone who enjoys solving complex technical problems, takes ownership of critical services and platforms, and is confident sharing their expertise and challenging existing approaches when there is a better way to do things.

Key Responsibilities

• Maintain and evolve the platform infrastructure that underpins our applications and services.
• Design, build and automate cloud infrastructure using Terraform and other Infrastructure as Code (IaC) technologies.
• Manage Kubernetes clusters and associated platform services, including provisioning, configuration, monitoring, upgrades, troubleshooting and automation.
• Develop and enhance CI/CD tooling and deployment pipelines using Azure DevOps or similar technologies.
• Monitor and optimise platform performance, reliability, capacity and security, implementing improvements where needed.
• Investigate and resolve complex infrastructure, platform and deployment-related incidents.
• Develop, maintain and enhance automation and configuration management solutions using PowerShell, Bash, Chef and equivalent technologies.
• Provide technical expertise and guidance on platform architecture, operational impact, security and risk.
• Contribute to platform roadmaps, technology standards and modernisation initiatives.

You will have strong hands-on DevOps and infrastructure engineering experience, alongside a good understanding of modern application development, deployment and operational practices.

We would particularly like to hear from you if you have experience with:

• Microsoft Azure infrastructure, platform services and automation.
• Kubernetes administration and container orchestration.
• Terraform and Infrastructure as Code (IaC).
• Azure DevOps or other CI/CD tooling.
• Administration and support of Windows and Linux operating systems.
• Infrastructure monitoring, performance optimisation and operational support.
• Infrastructure security, vulnerability management and remediation.
• Troubleshooting complex infrastructure, platform and application deployment issues.
• Monitoring and observability tooling such as Grafana, Prometheus or equivalent technologies.
• Configuration management and automation tooling such as Chef, Ansible or equivalent technologies.
• PowerShell, Bash or similar scripting languages.
• Networking, load balancing and application delivery technologies, including HAProxy.

Behaviours

• Takes ownership of technical outcomes and delivers high-quality solutions.
• Approaches problems analytically and methodically, balancing risk and practicality.
• Works collaboratively and positively across teams to achieve shared objectives.
• Communicates technical concepts clearly to both technical and non-technical audiences.
• Seeks opportunities to automate, simplify and improve existing processes.
• Explores and adopts emerging technologies, including AI-assisted tooling, to improve platform operations, automation and service delivery.

What we offer:

• 27 days of annual leave
• Full tech setup
• Support for your ongoing growth & development
• Enhanced Family Leave
• Flexible, hybrid approach to work
