• Troubleshooting - developing your diagnostic skills and learning how to apply basic troubleshooting techniques across a range of technologies.

As you progress through the apprenticeship, you’ll gain hands-on experience in:

Core Cloud & Automation Skills

• Terraform – building, managing, and automating infrastructure as code.
• AWS Cloud Infrastructure – deploying, securing, scaling, and operating cloud platforms.
• Docker – containerising applications and managing lightweight, portable environments.
• CI/CD Pipelines – understanding automated build, test and deployment workflows using tools commonly used in Companies House.
• Version Control (Git) – managing source code, collaborating through branches and pull requests.

Additional Technical Skills

You might also get the opportunity to learn more about:

• Programming Languages – exposure to languages used at Companies House, such as Java, Node.js and Python, plus scripting basics.
• SQL & MongoDB – querying, modelling, and working with relational and nonrelational databases.
• Unix/Linux – essential command line usage, system administration and troubleshooting.
• Networking Fundamentals – understanding VPCs, subnets, routing, firewalls and connectivity in cloud environments.
• Storage Technologies – object storage (e.g., S3), block storage, file systems, encryption and backup concepts.
• Monitoring & Observability – logging, metrics, alerting, dashboards and incident response principles.
• Security Foundations (DevSecOps) – identity & access management, secrets handling, vulnerability awareness and secure-by-design thinking.

You’ll benefit from additional core skills development, a supportive apprentice community, onsite parking, an onsite gym, and a variety of active social groups across Companies House.

You’re joining us at a time of exciting transformation, and you’ll play a real part in shaping how our systems evolve for the future.
