Director of Engineering - Cluster Networking (Remote)

About the Role

We are seeking a Director of Engineering for Cluster Networking to lead our global cluster networking infrastructure. This remote Director of Engineering role is crucial for building and operating high-performance, large-scale networking environments that support our GPU cloud platform and AI workloads.

What You'll Be Doing

• Define and evolve the multi-year technical roadmap for cluster networking, aligning architecture with Nscale's AI platform requirements and growth strategy.
• Own the design and evolution of high-performance networking fabrics (Ethernet, InfiniBand) for GPU clusters and AI workloads.
• Establish and maintain reference architectures and engineering standards across all regions and data centres.
• Lead end-to-end engineering delivery of cluster networking solutions—from design and lab validation to production deployment and optimization.
• Own the operational performance, availability, and reliability of cluster networking infrastructure globally.

Requirements

• 12+ years of experience in networking or infrastructure engineering, with at least 5 years in a senior technical leadership role.
• Deep hands-on experience designing and operating large-scale data centre or HPC networking environments.
• Proven expertise in high-speed Ethernet and/or InfiniBand fabrics supporting GPU or AI workloads.
• Strong background in data centre networking, routing protocols, congestion management, and high-availability design.
• Experience leading globally distributed engineering teams in high-growth or hyperscale environments.

Nice to Have

• Experience designing networking for large-scale GPU clusters or AI training environments.
• Familiarity with HPC networking topologies (Fat Tree, Rail, Dragonfly).
• Experience with SONiC, Cumulus, or other open networking platforms.

What We Offer

• Highly competitive package (base + equity) with reviews every 12 months.
• Human-First Flexibility: We treat you as humans first, allowing you to shape your day around life's moments.
• Join our thriving remote-first team, where geography is no barrier to impact or connection.
