About the opportunity

Exalto Consulting is supporting a confidential client on a nationally significant programme delivering secure digital services within a complex environment. We are looking for a Senior Front End Engineer who can contribute across the full development life cycle, with particular strength in modern Angular development, Node.js services and infrastructure automation using Terraform. This role sits within a multidisciplinary engineering team responsible for building and evolving resilient, cloud-based systems. The work combines hands-on engineering with technical input into design decisions, helping ensure systems remain scalable, secure and maintainable. The position is primarily remote, with occasional visits to London when collaboration or project activity requires it.

How you'll make an impact

• Designing and developing scalable Back End services using Node.js
• Building and maintaining modern Angular applications, using well-structured component architecture and state management
• Supporting the integration of large application components within wider web ecosystems
• Contributing to technical design discussions and translating requirements into practical, maintainable solutions
• Working with cloud infrastructure and Infrastructure as Code using Terraform
• Supporting reliable deployment through CI/CD pipelines and automated testing
• Participating in Agile delivery practices including sprint planning, stand-ups and retrospectives
• Collaborating with engineers, architects and stakeholders across distributed teams
• Contributing to incident response, change management and system reliability improvements
• Supporting knowledge sharing and good engineering practice across the team

Technology environment

The project uses a modern engineering stack focused on cloud-native development and automated delivery. Experience in the following areas will be particularly valuable:

• Angular - strong experience with modern Angular frameworks, component architecture and state management
• Node.js - deep understanding of asynchronous programming, API development and Back End services
• Terraform - practical experience implementing Infrastructure as Code for cloud provisioning and environment automation
• Cloud platforms - experience designing and managing scalable cloud environments (Azure preferred)
• CI/CD - experience building and maintaining pipelines using tools such as Jenkins
• Version control - strong Git workflows and branching strategies
• Agile tooling - comfortable working with tools such as Jira and Confluence

What you'll bring

We are looking for engineers who combine technical depth with a collaborative mindset. You'll likely bring:

• Strong experience delivering production-grade web applications and Back End services
• A solid understanding of software architecture, design patterns and development best practices
• The ability to work independently while collaborating effectively across teams
• Confidence contributing to technical decision-making and solution design
• Clear communication skills with both technical and non-technical stakeholders
• A structured approach to problem solving, system reliability and operational resilience
• Experience working in cross-functional or distributed engineering teams

Security clearance requirements (essential)

Due to the nature of the programme, active UK Security Clearance (SC) is required and must be transferable. Candidates must meet the following conditions:

• Clearance must remain valid (not older than 10 years) with at least 12 months remaining, ideally 18 months
• The clearance must have been used within the last 12 months on a government or policing contract requiring NSV clearance
• Candidates must not have resided overseas for more than 6 months during any break between cleared roles
