Cloud Network Test Engineer

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

Bitdeer AI Cloud is building a global-scale cloud networking stack spanning Cloud Enterprise Network (CEN / Transit Router), Cloud Express Connect (dedicated line access), and VPC networking. We are expanding the test team responsible for validating the reliability, correctness, and performance of these interconnect products across multi-region, hybrid-cloud, and large-scale routing scenarios.

• Own functional and reliability testing of the Cloud Enterprise Network (CEN): Transit Router route tables, route propagation/policy, cross-account/cross-region attachment, route conflict and convergence behavior at scale.
• Own functional testing of Cloud Express Connect: physical line access, VBR configuration, BGP peering, BFD-based failover, bandwidth/QoS, and end-to-end CPE interconnection validation.
• Own VPC network testing as the foundational layer: subnets/routing, security groups/ACLs, ENI, EIP/NAT, VPC peering, and multi-tenant isolation correctness.
• Validate data-plane forwarding correctness (encapsulation, MTU/fragmentation, ECMP hashing), high-availability failover, and performance/capacity (PPS/BPS, connection rate, control-plane convergence) at scale.
• Build automated test frameworks, integrate into CI pipelines, and drive fault-injection / long-duration stability testing as standard practice.
• Participate in requirement and design reviews from a testability/observability perspective; lead root-cause analysis and closure of production issues.

• 8+ years of experience in network testing, cloud infrastructure, or large-scale network operations; Bachelor's degree or above in CS, Communications, or related field.
• Deep understanding of cross-region / hybrid-cloud interconnect products (e.g. Alibaba Cloud CEN/Transit Router, AWS Transit Gateway/Direct Connect, or equivalents).
• Strong expertise in BGP (neighbor states, route attributes, path selection, route policy, convergence) and familiarity with BFD, VRRP, OSPF, and static routing.
• Solid understanding of TCP/IP, VLAN/QinQ, Overlay/tunneling (VXLAN, EVPN, GRE, IPSec), and NAT/conntrack principles.
• Proficient in Linux networking (netns, veth, bridge, bonding, iptables/nftables, tc) and packet-level troubleshooting (tcpdump, Wireshark, ethtool).
• Hands-on experience with traffic generation and test tooling (iperf3, scapy, TRex/DPDK-pktgen, or commercial testers such as Spirent/Ixia).
• Proficient in Python or Go for test automation; experience with pytest/Robot Framework, Git, CI/CD (GitLab CI/Jenkins), Docker, and Kubernetes.
• Hands-on experience with switches/routers (VLAN, LACP, BGP, BFD configuration) and building physical/virtual test beds.

• A culture that values authenticity and diversity of thoughts and backgrounds;
• An inclusive and respectable environment with open workspaces and exciting start-up spirit;
• Fast-growing company with the chance to network with industrial pioneers and enthusiasts;
• Ability to contribute directly and make an impact on the future of the digital asset industry;
• Involvement in new projects, developing processes/systems;
• Personal accountability, autonomy, fast growth, and learning opportunities;
• Attractive welfare benefits and developmental opportunities such as training and mentoring.
