Whitespace Careers

default

At Whitespace, we build intelligent systems that people can trust- AI and digital platforms that power defence, government, and leading commercial organisations. Our work sits at the edge of what’s possible, where technology meets security and real-world impact.
<br><br>We’re engineers, designers, and problem-solvers who care about clarity, precision, and purpose. Our teams create technology that helps national programmes run smarter and global businesses act faster.

We move quickly, cut through noise, and give talented people the space to build things that matter. <br><br>Whether it’s a secure AI platform for government or automation for a global enterprise, the challenge is the same: make complex systems simple, reliable, and human to use.<br><br>If you want your work to count - join us.

Why We're Here

<html><head></head><body><div>
<div>Own the decisioning layer behind high-stakes AI. We're hiring a platform Product Manager (up to Principal) to own the Decision Engine in Collective, our sovereign AI operating system for Defence, Government and regulated industries.</div>
<div>&nbsp;</div>
<div>About Whitespace<br>Whitespace moves AI from proof-of-concept into real operational use for Defence, Government and regulated industries. Collective, our sovereign AI operating system, connects governed data, domain context, reasoning and action with full auditability. It runs in the cloud, at the edge, on-premise and fully air-gapped, including classified settings. Our applications, including Operational Learning and Decision Intelligence, are live in operational environments today.</div>
<div>&nbsp;</div>
<div>The role<br>The Decision Engine is the set of platform services, components and models that every workflow and application on Collective uses to frame decisions, reason over evidence, generate and test options, and recommend action.</div>
<div>Your outcome is decision superiority: better, faster and more defensible decisions in every product built on Collective, including the ones nobody has built yet.</div>
<div>&nbsp;</div>
<div>This is a horizontal platform role. You won't own a workflow. You'll find the decision patterns shared across customers, deployments and application teams, then shape them with engineering and our AI and data science team into reusable, assured platform capability.</div>
