Business Development Manager - Defence

Valarian: A New Era of Sovereign Intelligence 

Valarian is a dual use technology company building critical tools to safeguard the future in an era of evolving global security challenges. Backed by a Series A funding round of $50m led by NEA, we are rethinking security beyond traditional military domains to address asymmetric threats that impact our technological advantage, economic strength, and democratic institutions. We provide the control infrastructure that allows government and regulated enterprise to put frontier-class AI to work safely.

We are bringing a frontier AI experience inside secure boundaries for the first time. Our technology supports mission critical workflows across government, healthcare, and enterprise, including:

• Scaling open-weight models without external inference endpoints.

• Putting frontier class AI to work across organisations through partnerships with other leading AI startups such as Perplexity. 

• Increasing operational resiliency for air gapped, on prem, and cloud based systems.

• Securing intellectual property and maintaining auditability for high stakes enterprise environments.

• Facilitating secure information flow during disaster response, M&A due diligence, and privileged legal communications.

We’ve only scratched the surface. Built in Britain by veterans of the Ministry of Defence, British Forces, Darktrace, and elite engineering backgrounds, we are driven by a shared mission to safeguard western democracy . Whether you join our London HQ or our wider global organisation, you’ll be part of a collaborative, high performing team creating the cutting edge software and infrastructure that defines the frontier of enterprise AI.

As a Business Development Manager - Defence at Valarian, you will define and execute our defence market strategy with a strong focus on building and protecting our commercial ecosystem across government, primes, integrators and end users. You’ll be responsible for securing how our organisation operates in the defence market day-to-day: from account mapping and stakeholder engagement, to bid and capture management, to compliance and assurance across systems. 

This is a hands-on leadership role combining strategy, architecture and execution. You’ll report directly to the Head of Delivery, and work closely with Product, Engineering, Legal, Compliance and Leadership to embed defence readiness into everything we build, while evolving our compliance posture across UK Government Security Classifications and relevant assurance frameworks.
