Principal Technology Innovation Engineer – National Security & Defence

The Opportunity

What happens when you give an experienced engineer the freedom to explore new technology, solve difficult problems and turn ideas into working solutions?

This is a role for someone who enjoys operating at the intersection of software engineering, emerging technology, research and solution design. You’ll have the opportunity to investigate new approaches, experiment with different technologies and develop prototypes and MVPs that can ultimately be applied to real-world National Security and Defence environments.

Rather than being tied to a single technology stack, you’ll be encouraged to understand the problem first and then determine the most appropriate technical approach.

Sometimes that will mean using established technologies in a new way. At other times, it could involve investigating a developing technology or building something that has never been attempted before.

About the Organisation

Our client is an established technology organisation specialising in National Security and Defence, with extensive experience delivering software engineering, research and digital infrastructure capabilities to customers operating in complex and highly secure environments.

The organisation has been built around a strong engineering culture, with technical professionals encouraged to experiment, share knowledge and challenge conventional approaches.

As the organisation enters an exciting period of growth and development, there is now an opportunity for an experienced technical professional to play an influential role in shaping its future technology capability.

The Role

This is a broad technical position with considerable variety.

You’ll work across engineering and business development activities, helping the organisation understand emerging technologies, assess their practical applications and translate technical concepts into tangible solutions.

Your responsibilities could include:

• Investigating new technologies and assessing where they could provide genuine value.


• Designing and developing prototypes, proof-of-concepts and MVPs.


• Providing senior technical input into customer proposals and bids.


• Working alongside engineers to introduce new technologies, approaches and development practices.


• Exploring technical solutions to complex problems within National Security and Defence environments.


• Supporting the development of new technical capabilities and service offerings.


• Researching emerging developments across software, infrastructure, AI and other specialist technology areas.


• Contributing to technical architecture and engineering decisions.


• Sharing knowledge and mentoring colleagues across areas of technical expertise.


• Working with the Business Development function to translate customer requirements into credible technical solutions.

You won't be expected to be an expert in every technology listed below. Curiosity, engineering judgement and the ability to learn quickly are more important than having a perfect checklist of skills.

Areas of Technical Interest

The role could involve working across a broad range of technologies and engineering disciplines, including:

• Artificial Intelligence and machine learning


• AI systems engineering and integration


• Natural Language Processing


• Computer vision and image processing


• Quantum technologies


• C++ and Python development


• Modern web technologies


• Cloud-native engineering


• Distributed systems and architecture


• Network protocols and communications


• Observability and monitoring platforms


• Message brokers and event-driven architectures


• Database technologies


• Web authentication and security


• Version control and CI/CD


• Linux and wider systems engineering

The precise focus will evolve as projects, customer requirements and technology developments change.

What We're Looking For

We're interested in engineers who are comfortable stepping outside their immediate specialism.

You may have developed your career as a software engineer, systems engineer, architect, R&D engineer or technical specialist before developing a broader interest in technology and solution design.

You'll ideally bring:

• Strong software engineering experience in one or more languages such as C++, Python, Java, JavaScript, Rust or similar.


• Experience developing or evaluating technical solutions across multiple technology domains.


• An understanding of modern distributed systems and software architecture.


• Experience working with Linux-based environments.


• Exposure to one or more major cloud platforms such as AWS, Azure or GCP.


• The ability to understand unfamiliar technologies quickly and determine their practical application.


• Strong problem-solving and technical design skills.


• An interest in emerging technologies and how they can be applied to real-world problems.


• The communication skills required to explain complex technical concepts to both technical and non-technical audiences.

Experience supporting pre-sales, bids, proposals or customer-facing technical engagements would also be valuable.

The Person

This role will suit someone who gets bored doing the same thing every day.

You're likely to be naturally curious, technically inquisitive and comfortable asking, "Is there a better way of doing this?"

You don't necessarily need to be the deepest specialist in one particular technology. Instead, we're looking for someone who can move between disciplines, understand unfamiliar concepts, experiment with new approaches and work out how technology can be applied to solve a particular problem.

You'll also be someone who enjoys working with other engineers and is happy sharing knowledge, challenging ideas and helping shape technical direction.

Why Join?

You'll have the opportunity to work on technically interesting challenges where the outcome has a genuine connection to National Security and Defence.

The role offers considerable technical variety, exposure to emerging technologies and the opportunity to influence the development of new technical capabilities.

For someone who enjoys engineering, learning and solving problems rather than being confined to a narrow technology stack, this is an opportunity to have a meaningful influence within an established and growing technical organisation.
