What You'll Be Doing

• Lead SDK architecture & development (Windows/Linux) used by internal teams and customers
• Design intuitive GUIs for R&D, production, and customer demos
• Integrate 3rd-party hardware drivers (USB3, CoaXPress, CameraLink)
• Collaborate cross-functionally with sales, QA, and product teams
• Mentor and upskill a growing software team
• Bring maturity to development through strong architecture, validation, and quality processes
• Engage in hands-on product work and occasional customer visits

What You Bring

• 7+ years in software development, with C/C++/C# SDK experience
• Strong background in driver integration, cross-platform development, and GUI design
• Comfortable with low-level development (e.g. drivers, firmware, FPGA integration)
• Solid grasp of software architecture, CI/CD, version control, and testing
• A technical leader with the ability to mentor others and drive process improvements

What so good?

• Shape next-gen products in space, defence, and high-performance imaging
• Work in a small, high-visibility team with direct access to leadership
• Full product lifecycle exposure: from concept? prototype? field
• Mix of autonomy, impact, and technical variety
• Office-based in Larne, but flexible core hours (10am–4pm; Friday: 10–2 or 10–12)
• Performance bonus & more
