Product Manager

TwinStream

This Head of Product role focuses on security products within a technically complex environment. You will lead product strategy and roadmap development while balancing custom client needs against long-term platform scalability.

What you’d own

  • Product vision, strategy, and roadmap management
  • Translating customer requirements into reusable core capabilities
  • Balancing technical debt, security, and operational efficiency
  • Cross-functional stakeholder alignment across engineering and commercial teams

Who it’s for

A fit if you…

  • You have experience in the cyber security or cross-domain space.
  • You excel at turning complex customer problems into scalable product features.
  • You are comfortable navigating highly regulated environments (government/defense).
  • You can communicate effectively with both technical and non-technical stakeholders.

Not for you if…

  • You prefer pure feature-delivery roles without strategic roadmap ownership.
  • You prefer working on simple, consumer-facing products without complex infrastructure constraints.
  • You prefer a role where requirements are clearly defined rather than ambiguous.

Reading between the lines

  • The emphasis on 'reusable capabilities' over 'customer-specific solutions' suggests a push to move away from bespoke consultancy toward a scalable product model.
  • The requirement for DV clearance and focus on 'cross-domain' implies a high-security, high-compliance environment with strict regulatory constraints.

Working across engineering, architecture, delivery, platform, service and commercial teams, you will ensure the product continues to deliver customer value while becoming easier and more efficient to develop, deploy, operate, maintain and evolve. This is a strategic product role focused on understanding the problems that matter, defining the outcomes we need to achieve and making informed decisions about where to invest.

Ensure completed capabilities achieve the intended customer and product outcomes. Product coherence and sustainability Protect the integrity and coherence of the product across components, customers and implementations.
