We’re looking for an Application Software Engineer to help build the user-facing tools and APIs that power our next-generation RF monitoring systems.
You’ll work across Windows and Linux platforms to develop applications and interfaces that handle vast amounts of data — transforming raw signal intelligence into usable insight for mission-critical users. This is a great opportunity to work at the intersection of embedded systems and high-level software, taking ownership of systems that span the full stack.
🔧 What You’ll Be Doing
Full software development lifecycle: from design and requirements to testing and deployment
Develop clean, high-quality software in C# for client-server systems
Build and maintain RESTful APIs to interface with embedded and distributed devices
Create and maintain functional specifications and documentation
Write unit tests and contribute to test automation
Perform peer reviews and help maintain code quality across the team
Collaborate with engineers across embedded, systems, and hardware disciplines
🧠 What You’ll Bring
Strong knowledge of C# and object-oriented programming
Experience developing and maintaining RESTful APIs
Familiarity with client-server architectures and data-heavy applications
Good grasp of design patterns, data structures, and Agile development practices
Solid problem-solving skills and attention to detail
Comfortable working independently and in a cross-functional team
Excellent communication skills
💡 Nice to Have
Degree in Computer Science, Engineering or similar
Familiarity with:
WPF or other modern UI frameworks
ASP.NET or similar web frameworks
Algorithm design and implementation
Linux shell scripting and cross-platform developmentWhy Join?
Real-world tech – You’ll work on applications that control mission-critical RF systems used globally
Cross-functional teams – Work closely with embedded, RF, and hardware engineers
Onsite + hybrid – Design, dev, and manufacturing are all in-house for fast feedback and rapid iteration
Ownership and learning – Autonomy to shape features and work across the stack
Flexible, impactful work – Help deliver tech-for-good used by defence and security customers worldwide
