Solution Architect - Contract

Work on Technology That Protects What Matters

At SiXworks, we build secure digital solutions that support Defence and National Security missions. Our teams work on complex problems where reliability, security, and speed of innovation matter.

We’re looking for a Solution Architect who enjoys solving difficult technical challenges and wants their work to have real operational impact.

What You’ll Do

As a Solution Architect, you’ll help design, build, and deliver secure digital solutions in highly secure environments. You’ll work alongside engineers, architects, and delivery specialists to develop technology that enables faster, safer decision-making for critical operations.

What We’re Looking For

We value people who take ownership, think critically, and enjoy working as part of a collaborative team tackling complex challenges. You don’t need to tick every box, but we’re particularly interested in people with skills/experience in:

• Developing and deploying Cross Domain Solutions, including their design, use, testing and assurance. 

• Sound understanding of the NCSC patterns and guidance for safely importing and exporting data. 

• Ability to assess the product marketplace for products which meet requirements of the functional components of the solution. 

• Ability to convey technical requirements for bespoke components required to software developers. 

• Ability to understand user requirements and translate these into solution design. 

• Ability to present complex technical information to non-technical audiences. 

• Experience of working with both hardware- and software-based cross domain approaches. 

• Strong knowledge of cryptography and public key infrastructure. 

• Experience of MOD systems and processes. 

• Experience of MOD assurance processes. 

It would also be desirable for you to have demonstratable experience of:  

• Supporting development in a Secure-by-Design methodology; 

• Experience of Data-Centric Security principles. 

• Experience working with Hardsec Cross Domain appliances. 

• Experience of cloud deployment automation. 

• Strong networking skills.

Just as important are curiosity, strong problem solving ability, and the motivation to continuously improve how technology is designed and delivered.
