We are seekingWe are seeking a Senior Director, Interconnection & Network Economics to own the architecture and economics of how Bitdeer's AI cloud connects to the rest of the world. You will decide what our border, interconnection and long-haul connectivity should be and what it should cost, from peering and Internet Exchange (IX) strategy and hyperscaler on-ramps to build-versus-lease decisions for data center interconnect (DCI). You will turn GPU-cluster performance requirements into a north-south network design and a delivered cost curve. You will work alongside our Network Infrastructure & Connectivity team, which sources, contracts and operates that connectivity, and set the target architecture and cost model they deliver against. This role suits a recognized interconnection practitioner who has run edge connectivity and optical transport for production GPU infrastructure.
What you will be responsible for- Own Bitdeer's traffic-exchange architecture and its delivered cost curve ($/Mbps, $/Gbps), and set the target interconnection architecture and cost model for our AI cloud and data center sites.
- Define and lead peering and IX strategy, including Bitdeer's public and private interconnection posture and IX participation, and represent Bitdeer in the peering and IX community.
- Set meet-me room (MMR) and border physical design standards, including separated MDFs, distinct power and cooling failure domains, and dual-homed cluster border switches.
- Design hyperscaler interconnect, including AWS Direct Connect, Azure ExpressRoute and Google Cloud Interconnect, and agree in advance the burst profiles both sides must support.
- Lead build-versus-lease architecture and costing for DCI, metro transport and dark fiber, and recommend the position for leadership approval before it is sourced and delivered.
- Model GPU-cluster SLA exposure at the border, including path-length asymmetry, ECMP hashing, jitter and cluster dropout, and turn it into design requirements and SLA-credit risk.
- Define Bitdeer's InfiniBand and RoCE posture at the north-south boundary so that border design supports GPU backend fabrics and their migration path.
- Contribute production InfiniBand and RoCEv2 experience to GPU cluster fabric design reviews (fat-tree, rail-optimized and dragonfly topologies), so that east-west fabric choices and the north-south border are designed together.
- Advise on fabric performance standards, including adaptive routing, DCQCN/ECN congestion control, traffic isolation and NCCL behavior, where they affect border design, cluster SLAs or cost.
- Select border platforms, including router versus switch and FIB and hardware scale, and recommend standards for approval and deployment.
- Advise on connectivity and GPU fabric incidents that have an architectural or cross-boundary root cause, and feed the lessons back into design standards and the cost model.
How you will stand out- 15+ years in network engineering and interconnection at internet, CDN, cloud or AI-infrastructure scale.
- Production accountability for edge connectivity and/or backbone optical transport supporting large-scale GPU or AI infrastructure across multiple data centers.
- Hands-on production experience with InfiniBand and RoCEv2 GPU fabrics (fat-tree, rail-optimized or dragonfly topologies; Nvidia, Arista and Cisco platforms), including RoCE migration planning, and familiarity with UFM, adaptive routing, DCQCN/ECN congestion control and NCCL tuning.
- Deep peering and IX expertise and a track record in network economics: measurably reducing delivered cost per Mbps while supporting traffic growth across large IX footprints and multi-Tbps peak traffic.
- Strong DCI and long-haul design skills: 400G-class DCI, DWDM and optical transport, build-versus-lease costing, optical lead times and in-line amplifier (ILA) site support.
- WAN-scale routing expertise in eBGP/iBGP, MPLS/RSVP-TE and EVPN-VXLAN, with an informed position on SRv6.
- Ability to connect network behavior to business outcomes, such as tracing jitter through ECMP hashing to GPU job dropout and SLA-credit exposure.
- Experience designing hyperscaler interconnect (Direct Connect, ExpressRoute, Cloud Interconnect) with cloud partners.
- Clear written and verbal communication, with the ability to make the architecture and build-versus-lease case to senior leadership and to work closely with procurement and operations teams.
- Bachelor's degree in Computer Science, Electrical Engineering, Telecommunications or a related field, or equivalent industry experience.
- Recognized standing in the interconnection community
What you will experience working with us- A culture that values authenticity and diverse perspectives.
- An inclusive, respectful environment with open workspaces and an energetic, start-up spirit.
- A fast-growing company with opportunities to network with industry pioneers and enthusiasts.
- The ability to contribute directly and make an impact on the future of the digital asset and AI computing industry.
- Involvement in new projects and in developing processes/systems.
- Personal accountability, autonomy, rapid growth, and learning opportunities.
- Attractive benefits and development such as training and mentoring.
