Job description

Our Software Engineering team develops bespoke capabilities for clients in the Cyber Security domain. We may be building assured products that prioritise engineering rigour and reliability, rapid solutions that bring together existing tooling for high-impact results, or blended operational systems that combine software, hardware, networks and third-party technologies to address real-world challenges in the field.

Common to all is a commitment to technically led decisions, meaningful technical challenge, and seeing our work make it off the shelf and into the hands of our customers.

We’re looking for **Integration and Test Engineers** who enjoy the point where design, software, hardware and networks meet. Rather than concentrating on developing a single component, you will be responsible for bringing components together into complete working systems, understanding why they do — or occasionally don’t — behave as expected, and producing the evidence needed to demonstrate that the resulting capability works in representative and operational environments.

Our systems may combine bespoke applications, Linux or Android devices, networks, infrastructure, commercial products, open-source tooling, specialist hardware and communications equipment. You should enjoy getting hands‑on with unfamiliar technologies, understanding their interfaces and constraints, automating away repetitive work, and methodically isolating problems that span several components.

This role sits between systems engineering and software engineering. You are likely to write Python or Bash, build test tooling, configure networks, automate deployments and investigate source code, but bespoke application development is not the primary objective. Your focus is making the **complete system work reliably**.

We’re led by engineers and empowered to optimise our lightweight engineering processes with the knowledge gained from each project. We want repeatable integration and test where it provides value, while retaining the ability to move quickly when developing new capabilities.

We are ideally looking for candidates who hold an active Security Clearance to join our team; however, we will consider sponsoring new clearances for candidates who meet our technical requirements.

Key Responsibilties

As part of our team, you may be:

• Bringing together software, hardware, networks, infrastructure and third‑party technologies into complete working systems.
• Developing integration approaches, representative test environments, deployment automation and supporting tooling.
• Designing and executing system‑level tests covering functional behaviour, performance, resilience and failure handling.
• Investigating complex failures across software, operating systems, networks, configuration and hardware and working with engineers to resolve root causes.
• Supporting demonstrations, trials, deployments and customer acceptance while feeding integration findings back into system design and interfaces.

For this role you will be hands‑on in the day‑to‑day delivery of projects. Typically, this will see you working closely with a small number of engineers and taking ownership of getting a complete capability from individually working components to a dependable integrated system.

Desirable Skills

Successful candidates will have strong experience in a subsection of the following areas:

• 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.

Experience with Android, embedded Linux, specialist hardware, RF, telecommunications systems or operational deployment environments would be useful for some of our projects, but not essential. You don’t need to be an expert developer, network engineer and hardware engineer simultaneously. We are looking for technically curious engineers with strong fundamentals who are comfortable crossing those boundaries when solving a problem.

This vacancy is for experienced engineers who get satisfaction from taking a collection of individually capable technologies and turning them into a reliable, repeatable, tested system that works outside the lab.

Work Benefits

• Promotions are based on technical excellence and reviewed regularly.
• 25 days holiday per year (with bank holidays on top), option to buy up to 5 days per year.
• Level up with an extra day of holiday per year, up to an extra 5 days, starting from 2 years’ service.
• We offer financial support to cover HMRC allowable costs of relocating if you’re moving to the area.
• Training and development opportunities to support your career aspirations
• O’Reilly books subscription which provides access to huge range of technical books
• Regular events including internal technical conferences, company socials and pizza‑fuelled lunchtime seminars.
• Free seasonal fruit, tea, coffee, milk, squash and hot chocolate.

Health Benefits - Private medical including access to

• Private online GP, and a helpline to speak with various healthcare professionals.
• Physiotherapists, osteopaths or chiropractors for muscle, bone, and joint pain.
• Mental health - counselling, and specialist consultations and treatment with psychologists and cognitive behavioural therapists.
• Annual Health assessment.

Financial Benefits

• A company bonus scheme so that everybody is rewarded for company success. This is an annual award that is based on the company hitting its targeted forecast. We have achieved this every year to date.
• 8% company contribution to pension with no minimum requirement for employee contribution.
• Death in Service cover of 4x base salary.

Lifestyle Benefits

• Enhanced maternity/paternity/adoption leave: 12 weeks maternity leave at full pay as soon as you join, further enhanced to 20 weeks full pay from 2 years’ service. 2 weeks paternity leave at full pay as soon as you join, further enhanced to 4 weeks full pay from 2 years’ service.
• Enhanced cycle-to-work scheme including the ability to purchase a bike over £1,000 (e‑bikes, specialist cycles and trikes allowed).

Salary

We’re open to hiring a range of levels for this role salary will be reflected on experience. We will have candid discussions around the package on offer in our initial conversations so you can know what to expect should you receive an offer from us.

Location

We are based in the centre of Cheltenham in a stunning new build contemporary office, 5 minutes walk from the local shops and cafes.

**Additional Details**

Our interview process is quick and to the point: if you look like a good fit for the role, we’ll schedule a brief call to discuss it in more detail and answer any questions you may have. If that goes well, we’ll arrange a technical interview to understand your level of experience. We aim to get back to you with an answer within a couple of days of the technical interview.

Please note, due to sensitivity of the role, successful applicants must be eligible and willing to undergo (or already hold) SC clearance.
