Help Build Europe's Hypersonic Capability
At Hypersonica, we’re redefining what’s possible in European defence technology. We exist to deliver speed, resilience, and technological independence at a pace that sets a new standard. We are a small, elite team working on problems that matter, and solving them fast.
By joining Hypersonica, you’re not stepping into a predefined role. You’re joining a talent dense environment where every individual shapes the direction of the company. Our philosophy is to hire a small number of exceptional people with broad, deep technical capability, strong judgement, and the ability to operate autonomously.
We hire for talent, not rigid boxes. This role represents a business need, but the way it evolves will be shaped by the individual. If you’ve achieved what others said was impossible, or you bring a unique combination of skills that doesn’t fit a traditional mould, we want to hear from you. The work you do here directly contributes to Europe’s technological independence.
What you'll do
- Own day-to-day information security and cyber compliance for our UK operations, working closely with the CISO and the wider group security function.
- Lead the annual Cyber Essentials Plus renewal from start to finish: defining the scope, finding and fixing gaps, gathering evidence, and working with the certification body through the assessment.
- Get the company ready to meet DEF STAN 05‑138 at higher cyber risk levels. That means gap analysis, a prioritised roadmap, putting controls in place, and building the evidence that MOD supplier cyber risk assessments need.
- Maintain and improve our ISO 27001 ISMS, including risk assessments, the Statement of Applicability, policies, internal audits, and management reviews.
- Run information security risk management and threat modelling, and turn the results into clear priorities for the business.
- Work with IT and infrastructure teams on technical controls, including identity and access management, endpoint hardening, vulnerability management, logging and monitoring, and backup and recovery.
- Manage supplier and subcontractor security, including flowing contractual cyber requirements down to them and assessing their security posture.
- Own the incident response plan, run exercises, and coordinate response and reporting to customers and authorities when incidents happen.
- Deliver security awareness training suited to a fast-moving engineering organisation.
- Report security posture, risks, and compliance status to leadership in clear, actionable terms.
Who you are
- A hands-on information security professional with experience delivering cyber compliance in the defence or government supply chain.
- Practical experience running Cyber Essentials / Cyber Essentials Plus certifications and working to DEF STAN 05‑138 and the MOD's supplier cyber protection requirements.
- Solid experience implementing or auditing an ISO 27001 ISMS. A Lead Implementer or Lead Auditor qualification, or certifications such as CISSP or CISM, is a plus.
- Enough technical depth in cloud identity, endpoint management, and network security to judge controls in practice, not just on paper.
- Familiarity with UK Government Security Classifications and MOD security requirements for industry is a strong advantage.
- Able to explain security clearly and pragmatically to engineers, leadership, and auditors alike.
What we offer
- A mission driven environment with the opportunity to work on one of Europe’s most consequential defence challenges, with direct impact on sovereign capability and security.
- Daily collaboration with top experts across engineering, operations, and defence, with real opportunity to learn from the best, contribute, and grow.
- High ownership and autonomy; no time tracking, no micromanagement, just clear objectives and accountability for outcomes.
- A fast paced environment where good ideas are implemented quickly, and feedback from test and flight drives real decisions.
- A culture that values clarity, integrity, and excellence, and supports people who take initiative and push boundaries responsibly.
- Competitive compensation and real share options aligned to responsibility and impact, not tenure or hierarchy.
At Hypersonica, every hire raises the bar. We are deliberately small, intensely capable, and deeply mission-driven. If this role feels like a strong fit, or if you believe you bring something exceptional that goes beyond the description, we encourage you to apply.
Hypersonica is an equal-opportunity employer and assesses candidates solely on merit, capability, and potential.
You can apply directly to this role or reach out to Nathan Sweeney, Head of Talent. We review every application and aim to respond to all candidates within two weeks, whether the answer is yes or no.
