Data Engineer – National Security | eDV Sponsorship
Location: Central London, 5 days onsite
Salary: £60,000 – £100,000 depending on experience
Clearance: Active SC or DV required
⭐ Enhanced DV (eDV) sponsorship provided
We’re supporting an fast-growing engineering SME that is expanding its presence across the UK National Security space and looking to build out its Data Engineering capability in London.
A major part of this opportunity is the chance to progress your existing SC or DV clearance to enhanced Developed Vetting (eDV).
Alongside this, you’ll be joining a business at an exciting point in its growth. The team is still relatively small, meaning you’ll have the opportunity to make a genuine impact, develop your technical skills and progress as the company expands.
They’re looking for technically capable, curious engineers rather than people who simply tick every box on a job description. If you have strong engineering fundamentals, enjoy solving difficult problems and want to continue developing your career within National Security, they’re keen to speak.
What you'll be doing
- Designing and building scalable data pipelines and platforms
- Ingesting, transforming and processing complex structured and unstructured datasets
- Developing data solutions supporting analytics, AI and machine learning
- Working with technologies including Python, PySpark, Spark and SQL
- Working across modern cloud and data engineering environments
- Collaborating closely with Software, Data and Platform Engineers
- Improving data quality, reliability, scalability and performance
- Contributing to technical design and architecture decisions
- Working across greenfield and evolving National Security programmes
- Taking on greater technical responsibility as the team grows
What we're looking for
- Experience in Data Engineering, Software Engineering or a closely related technical discipline
- Strong programming capability, ideally Python
- Experience with data processing, transformation or pipeline development
- Knowledge of SQL and data modelling
- Strong problem-solving and engineering fundamentals
- An ability and willingness to learn new technologies
- Someone who enjoys working within a small, collaborative and hands-on engineering environment
- Ambition to develop technically and progress as the business grows
- Current SC or DV clearance
- Ability to work 5 days onsite in Central London
Desirable experience
- Experience with PySpark / Apache Spark, AWS, ETL/data pipelines, batch or streaming architectures, Kubernetes/containerised environments, AI/ML,
- Previous work within Defence, Government or National Security environments would be beneficial.
- You don't need experience across all of these areas. Technical aptitude, curiosity and the ability to learn are equally important.
Why join?
The business is offering successful candidates a route from SC/DV into enhanced DV, supporting you through training and progression towards your career in engineering, and enabling you to work within some of the UK's most sensitive National Security environments.
- Gain enhanced DV (eDV) clearance
- Access highly sensitive National Security programmes
- Progress your career as the business and engineering team expand
- Receive ongoing training and technical development
- Work across modern Data, AI and Machine Learning technologies
- Take on increasing levels of responsibility and influence
- Work closely with senior engineers and leadership
- Help shape the technical capability of a growing business
If you’re an SC or DV-cleared Data Engineer, or a Software Engineer looking to move further into Data, I’d be keen to hear from you.
Equally, if someone in your network could be a good fit, I’d really appreciate an introduction. We offer a £500 referral bonus for any candidate you recommend who goes on to start a permanent or contract role through Frontier Resourcing.
