We’re seeking a Senior Network Engineer who combines deep technical expertise with a passion for solving real business challenges. In this role, you’ll lead the design, deployment, and optimization of enterprise network solutions that connect people, systems, and locations seamlessly across South Africa. You’ll be the trusted technical advisor for our enterprise clients—guiding them through complex network transformations involving campus networks, SD-WAN, wireless infrastructure, data centres, and security. Your work will span the full lifecycle: from understanding business requirements and designing integrated solutions, to hands-on implementation, ongoing optimization, and building long-term advisory relationships. This isn’t a role where you disappear after deployment. You’ll stay present—anticipating challenges, troubleshooting complex issues, mentoring junior engineers, and continuously finding ways to enhance performance and security. You’ll work across the iOCO family, bringing together diverse expertise to deliver solutions that just work. If you’re someone who can translate technical complexity into business value, who takes ownership of the entire client experience, and who thrives on both the technical depth and the human connections this work requires—this role is for you.
