Integration and Test Engineer

Salary: £61,000 - 101,000 per year

Requirements:

• We are looking for experienced engineers with strong fundamentals who are comfortable working across software, hardware, networks and infrastructure.
• Strong hands-on experience integrating and troubleshooting complex systems involving multiple technologies or components.
• Strong Linux, scripting and automation skills using technologies such as Python, Bash or similar.
• Good networking fundamentals and experience diagnosing networked systems using logging, packet capture or protocol-analysis tools.
• Experience with integration or system testing, test automation, CI/CD, containers, virtualisation or configuration-management tooling.
• Strong fault-isolation and root-cause analysis skills, with confidence working across software, hardware, infrastructure and third-party components.
• We are ideally looking for candidates who hold an active Security Clearance, although we may sponsor new clearances for candidates who meet our technical requirements.
• Experience with Android, embedded Linux, specialist hardware, RF, telecommunications systems or operational deployment environments would be useful, but is not essential.

Responsibilities:

• Bring together software, hardware, networks, infrastructure and third-party technologies into complete working systems.
• Develop integration approaches, representative test environments, deployment automation and supporting tooling.
• Design and execute system-level tests covering functional behaviour, performance, resilience and failure handling.
• Investigate complex failures across software, operating systems, networks, configuration and hardware, and work with engineers to resolve root causes.
• Support demonstrations, trials, deployments and customer acceptance while feeding integration findings back into system design and interfaces.
• Work hands-on in the day-to-day delivery of projects, taking ownership of getting a complete capability from individually working components to a dependable integrated system.
• Automate repetitive work and methodically isolate problems that span several components.
• Write Python or Bash, build test tooling, configure networks, automate deployments and investigate source code as needed to make the complete system work reliably.
