Job description

ViVA Tech Talent are proud to be exclusively partnering with a hiring for a fast-growing cybersecurity company in Belfast, who are looking for a Lead C/C++ Engineer. They are at the cutting edge of what they do and this opportunity is not to be missed!

Our client protects connected devices and critical digital infrastructure. You'll own the embedded software architecture — the real design authority, not just a title — building secure communications software that has to work flawlessly on constrained, low-power hardware where there's no room for sloppy engineering.

This isn't a role where you disappear into the codebase and never resurface. You'll split your time roughly 50/50: hands-on architecture and delivery, and being the technical face in front of clients and partners. Alongside that, you'll lead a small team — not just allocating tickets, but genuinely mentoring, motivating, and building a culture people want to stick around for.

What you'll be doing:

• Architecting and delivering embedded software — libraries, drivers, secure comms networking — that meets serious security and compliance standards
• Taking prototypes rapidly toward market
• Owning schedules and technical decisions across multiple concurrent projects
• Representing the engineering team in client and partner conversations

What we're looking for:

• Extensive hands-on C/C++ embedded development, with real experience architecting production-grade systems
• Proven team leadership — you've actually managed and grown engineers, not just reviewed their PRs
• Bonus points for secure comms/networking experience, applied cryptography knowledge, or familiarity with safety/security compliance frameworks (MISRA, ISO 62443, DO-178C and similar)

What you'll get:

• up to £75,000 base
