Technical Project Manager

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 Technical Project Manager who enjoys solving difficult technical challenges and wants their work to have real operational impact.

What You'll Do

As a Technical Project Manager, you will lead the development and evolution of SiXworks' internal secure IT platform, ensuring it is robust, scalable, and capable of becoming a marketable product offering for external customers. This role combines technical delivery, strategic investment management, and innovation leadership, driving SiXworks' position as a leading IT innovator within the Defence and Security sector.

Your work may include:

Project Leadership & Delivery

• Deliver technical IT projects to time, cost, and quality, ensuring all outcomes are secure by design.

• Manage the development lifecycle of the internal secure IT platform, from requirements to release.

• Plan projects comprehensively and realistically, establishing clear milestones, budgets and delivery expectations.

• Ensure projects are resourced appropriately and delivered responsively, flexibly, and efficiently.

• Apply the most appropriate project methodology and adapt governance as needed for agile, technical environments.

• Lead and maintain robust project governance, including forecasting, reporting, and risk management.

• Oversee project contracts, schedules, resources, equipment, and information.

Technical & Security Awareness

• Maintain a good understanding of relevant technologies, secure architectures, and solution options.

• Ensure internal platforms and developments meet the security requirements expected in MOD secure environments.

• Work closely with engineering and security teams to ensure compliance with best practices and accreditation pathways.

Internal Investment & Commercialisation

• Manage and prioritise internal investment initiatives that contribute to the secure IT platform and related innovations.

• Work with stakeholders to shape internal R&D concepts into commercially viable offerings.

• Ensure that platform development aligns with potential customer needs and market opportunities.

• Contribute to business cases and investment proposals for capabilities that may be sold to other organisations.

• Support early-stage proofs-of-concept and demonstrators, ensuring they are positioned for future commercial adoption.

Stakeholder Engagement & Team Leadership

• Build strong relationships with internal customers, understanding operational and business needs.

• Direct and motivate project teams, ensuring they remain engaged, informed, and aligned.

• Promote knowledge sharing and collaboration across project teams and technical groups.

• Foster a happy, fulfilling working environment and ensure fair and equal treatment of all employees and associates.

• Assist with recruitment, selection, and capability development.

Strategic Contribution

• Contribute to SiXworks' wider strategy in business growth, innovation, and secure technology development.

• Maintain and develop professional and technical knowledge of relevant technologies, methodologies, and security domains.

• Build trust and long-term relationships with directors, colleagues, suppliers, partners, and clients.

• Maintain (at least) SC level clearance.

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:

• Significant industry experience delivering technical projects within MOD secure environments.

• Experience developing and maturing internally funded IT capabilities into commercially viable offerings.

• Strong technical awareness of secure IT platforms, system architectures, and security principles.

• Excellent analytical skills, able to evaluate data, options, and performance metrics.

• Ability to operate at pace and manage multiple high priority initiatives.

• Demonstrable experience selecting and applying project methodologies (e.g., Agile, Scrum, Waterfall, Hybrid).

• Exceptional interpersonal, communication, and negotiation skills.

• Outstanding organisational, leadership, and motivational abilities.

• Excellent attention to detail and time management skills.

• Strong decision-making capability, informed by both technical and commercial considerations.

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