Keen to join a company that champions growth and development? Join a fast-growing infrastructure software company backed by a top-tier venture firm, having delivered 800% ARR growth over the past 12 months. The organization has built the leading network automation platform for AI clouds, with 35+ live GPU cluster deployments globally, sitting at the centre of one of the biggest bottlenecks in the largest infrastructure buildout in history. This is a great opportunity for a Senior Network Engineer to move beyond traditional networking and guide customers from proof of concept through to full production on demanding GPU infrastructure deployments. The ideal candidate will design and implement EVPN/VXLAN datacentre fabrics from scratch, own two to three high-impact customer accounts as their primary technical contact, and support automation and operational readiness using tools like Terraform. This is a hands-on, customer-facing role splitting time roughly evenly between implementation and ongoing support. Ready to take your expertise to the next level? Get in touch today!
