AI Cloud Network Architect [Remote]

Bitdeer is a world-leading technology company for AI and Bitcoin mining infrastructure.

Bitdeer is committed to providing comprehensive Bitcoin mining solutions for its customers and building AI computational infrastructure to support the AI revolution. Bitdeer handles complex processes involved in computing such as equipment procurement, transport logistics, data center design and construction, equipment management, and daily operations. Bitdeer also offers advanced cloud capabilities to customers with high demand for artificial intelligence.

Headquartered in Singapore, Bitdeer has deployed data centers across multiple countries, including the United States, Norway, Bhutan, and Ethiopia.

As global demand for AI compute capacity grows at an unprecedented pace, we are building the next generation of hyperscale intelligent computing infrastructure. We are looking for a seasoned network architect with global vision and world-class technical expertise to join our team. You will lead the end-to-end architecture design of AI Data Center Networks (AIDC), high-performance Data Center Interconnect (DCI), and global backbone networks serving large-scale GPU clusters and AI training/inference workloads.

Responsibilities

• Network Planning & Architecture: Engage deeply with NVIDIA, leading network equipment vendors, ISPs, and colocation partners; translate business requirements and cloud platform development architecture into top-level designs spanning AIDC internal networks, DCI, and the global backbone. Own the planning and implementation of foundational resources including IP addressing, VLAN/VXLAN, and bandwidth, while charting a forward-looking network evolution roadmap.
• Lead end-to-end AIDC internal network architecture, covering GPU cluster interconnects (InfiniBand / RoCE), Spine-Leaf / Clos topologies, front-end business networks, and out-of-band management networks.
• Collaborate with the cloud platform engineering team on Underlay network architecture design and Overlay network integration (SDN controllers / VxLAN / EVPN, etc.).
• Own congestion control tuning and standard-setting for hyperscale cluster networks, including PFC, ECN, and In-band Network Telemetry (INT).
• Produce architecture documentation (HLD / LLD), network topology diagrams, configuration standards, and SOPs.
• Identify risks in existing network architectures, develop improvement roadmaps, and drive execution to completion.

• Bachelor's degree or above in Computer Science, Telecommunications, Electronics, or a related field; 8+ years of network architecture design and planning experience at a hyperscale internet company, top-tier cloud provider, or multinational backbone operator.
• Deep understanding of network requirements for AI compute clusters; expert-level proficiency in InfiniBand (IB) and RoCEv2 architecture design.
• Familiarity with high-performance network topologies such as Rail-Optimized architectures; hands-on experience planning and deploying 10,000- to 100,000-GPU-scale cluster networks is a strong plus.
• Solid command of data center routing and overlay technologies including BGP, OSPF, ECMP, VxLAN, and EVPN; in-depth knowledge and practical experience with Segment Routing (SR-MPLS / SRv6).
• Familiarity with optical transport networks, DWDM technology, and global backbone peering/transit strategies.
• Exceptional cross-functional and cross-cultural communication skills with the ability to align diverse stakeholders on large-scale, complex projects; strong resilience under pressure and a technology-forward mindset.
