Location: Singapore

Company

hirify.global builds enterprise software infrastructure for capturing, cataloging, refining, enriching, and protecting massive datasets used for real-time analysis and AI training and inference.

What you will do

• Define reference network architectures for VAST deployments, including L2/L3 fabrics, BGP, EVPN/VXLAN, RoCEv2, and QoS policies.
• Build and operate validation labs for switch qualification, interoperability testing, performance characterization, and customer-issue reproduction.
• Evaluate switches, network operating systems, and NICs from NVIDIA, Arista, Cisco, Juniper, and other vendors.
• Investigate complex issues across GPUs, network fabrics, and storage, including congestion, packet loss, MTU, latency, PFC, and ECN behavior.
• Convert technical findings into documented best practices, automation, and product feedback for R&D.
• Collaborate with R&D, QA, Support, Product, customer engineering, and networking vendors.

Requirements

• Strong data center networking fundamentals at CCNP level or equivalent hands-on experience.
• Practical expertise with BGP and L3 routing, including eBGP/iBGP, ECMP, route policy, multipath, and BGP-based fabrics.
• Experience designing and troubleshooting L2 and L3 data center networks.
• Ability to troubleshoot routing, ARP/ND, MTU, congestion, packet loss, and latency across network layers.
• Working knowledge of Linux networking, including interfaces, VLANs, routing tables, namespaces, and MTU.
• Experience with tcpdump, Wireshark, iperf, and standard network diagnostic tools, plus strong technical writing skills.

Culture & Benefits

• Research- and design-focused engineering work rather than a support-queue role.
• Direct collaboration with engineering teams and networking vendors.
• Opportunity to work on GPU fabrics, lossless Ethernet, RDMA, and storage protocols operating at line rate.
