Role

We are hiring a Systems Engineer to help design, integrate, and deliver defence technology products from concept through deployment. This role sits at the intersection of product, engineering, operations, and users: turning ambiguous mission needs into clear system requirements, architectures, interfaces, and verification plans.

You will work across mechanical, electrical, software, manufacturing, and commercial teams to make sure our systems are coherent, buildable, testable, and ready for real-world use. You will define requirements, manage trade-offs, document interfaces, coordinate integration, and help drive technical decisions that balance speed, reliability, and operational value.

You will be responsible for building the systems engineering backbone at Allied as we scale: requirements management, system decomposition, verification and validation, configuration control, and technical risk management. You will help translate customer and operator feedback into product direction, while keeping engineering execution grounded in measurable outcomes.

This is a hands-on role for someone who is comfortable moving between high-level architecture and detailed execution. You should be able to reason from first principles, communicate clearly with technical and non-technical stakeholders, and take ownership of complex problems in a high-accountability environment.


About Allied

We’re a defence technology company reimagining how capability gets developed, built, and deployed. Our team comes from military service, government, and engineering — united not by background but by purpose. We work as a circle of peers, not a hierarchy. We prove what works in weeks, not years.

We’re backed by leading investors and working with best-in-class partners to strengthen western democracies. We don’t say that lightly.


About You

  • Experience in systems engineering, product engineering, mission engineering, or a related technical discipline
  • Strong ability to turn ambiguous user needs into clear requirements, interfaces, and verification plans
  • Experience working across hardware, software, operations, and manufacturing teams
  • Comfortable managing technical trade-offs, dependencies, and risks across complex systems
  • Familiarity with configuration control, requirements management, integration, verification, and validation
  • Able to communicate clearly with engineers, operators, customers, suppliers, and leadership
  • Experience in defence, aerospace, automotive, robotics, or other safety- or mission-critical environments

You are

  • Comfortable operating in a small, high-accountability team
  • Highly ownership-driven with strong internal standards
  • A structured thinker with a bias toward practical execution
  • Calm under pressure
  • Able to build systems from first principles
