Defence Tech5–10+ employees

Valteros is a London-based defence startup protecting democracies from information warfare, one of the defining security threats of the decade.

NATO has recognised cognitive security as an emerging domain of conflict, and artificial intelligence and online polarisation are making it harder to counter every year. Our solution: we build multi-agents modelling platforms to simulate the impact of these threats.

We closed a £2M pre-seed round in June.

What you will do

Execute across the commercial landscape by leading high-stakes conversations and developing strategic partnerships with government agencies and national security partners.
Drive product direction and internal operational efficiency by identifying critical bottlenecks and implementing scalable systems without waiting for direct instruction.
Context-switch between high-level strategic planning and boots-on-the-ground execution to ensure the company meets its milestones in a fast-paced defence environment.

Who this is a fit for

Demonstrates 0–5 years of experience with exceptional intellectual horsepower and the ability to thrive in a high-agency, generalist environment where initiative is the primary driver.
Possesses a genuine interest in defence and national security, with the legal eligibility (UK, EU, or US national) required to obtain UK security clearance.
Available to start in London or Oxford by August or September 2026, bringing a proactive mindset to build a generational company from the ground up.

Why this role is remarkable

Work on technology addressing one of NATO’s recognized emerging threats, building multi-agent platforms that model narrative spread and adversarial behavior to protect democratic resilience.
Join at the ground floor of a £2M pre-seed startup with significant equity potential and direct visibility into every aspect of scaling a mission-driven defence company.
Collaborate directly with the founder in a role that prioritizes high agency and impact, where you will solve complex problems across strategy, operations, and product.
