Senior Engineer (System Design Authority)

Company: Drumgrange Ltd

Location: Chertsey

Posted: April 18th, 2026

We are looking for a highly experienced and enthusiastic Senior Systems Engineer to lead a major project team in the role of System Design Authority. You will be responsible for the delivery of a complex system involving specialist sensors, electronics and signal processing firmware and software to C4ISR customers.


As one of the most senior engineers on the project, you will lead the team to successfully complete system design and development, system and sub-system implementation as well as integration and testing, and will gain customer acceptance ensuring all design requirements are met. You should also be able to identify potentials for system enhancements and upgrades where appropriate and support the development of roadmaps to achieve these changes as well as provide strong technical governance and mentoring of the design team and assist the project manager in reporting to a variety of internal and external customers and stakeholders.


The work is predominantly related to sensor and communications networked systems but also includes sensor processing and soldier-worn combat systems. Currently, the work covers Land systems but has the potential to evolve into other associated domains in the future.


Why Drumgrange?

When you join Drumgrange, you will be joining one of the last independent, family-run engineering companies in the UK defence industry.


For a company our size, we have a wide portfolio of projects. From working out how to integrate land sensors onto their respective platforms to going out to sea to carry out trials, you can expect to work on a variety of interesting projects with meaningful, real-world impact with stakes that go beyond delivering value to the shareholders.


As a Drumgrange employee, you get a rare opportunity to be involved all the way through the engineering lifecycle, from the bid stage, research, design, development, through to product/capability integration and end-of-life support. With only a few levels between junior roles and senior management, hard work hardly goes unnoticed, and there are plenty of opportunities to create a change. So if you are looking to hit the ground running, have a passion for engineering excellence, and are interested in building a rewarding career that gives you a sense of purpose, you will be a great fit at Drumgrange.
