A note from the founders
Oxford Dynamics is at an inflection point.
We operate in some of the most complex and high-stakes environments in the world defence - national security, AI and robotics. The decisions we make now will define not just how fast we grow, but who we become.
You will work closely with the whole team. You will be trusted with judgment calls. You will influence the business. And you will see the impact of your work every day.
If you are excited by ownership, pace and purpose, and by building something that genuinely matters - we would love to hear from you.
Who we are
Founded in 2019, Oxford Dynamics is a fast-growing UK frontier technology company developing both digital and physical AI systems built to operate in dynamic, mission-critical environments.
At the core of everything we build is AVIS™ (A Very Intelligent System), our orchestration platform: the intelligence layer that fuses multi-modal data, including text, imagery, telemetry and sensor feeds, so operators can interrogate complex information at speed and make better decisions under pressure. AVIS™ powers our digital decision products, such as ORION for multi-source decision-to-effect, and it powers our physical platforms, including STRIDER for CBRN operations and BARBARIAN for explosive ordnance disposal. The same brain reasons across the screen and the machine.
We work where wrong decisions can be catastrophic, partnering with defence and security organisations internationally to help protect nations, infrastructure and lives
