Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior Engineer, Compute Fabric & Network Architecture, Project Sunrise - **Company:** Blue Origin - **Location:** Denver, CO, United States - **Experience:** Expert - **Salary:** $133,500.0 - $186,899.0 - **Contract:** Permanent contract - **Skills:** Systems Engineering, Biometrics, Computer Networks, Data Centers, Network Topologies, InfiniBand, Machine Learning, Network Architecture, Network Switches, Information Technology - **Published:** October 11, 2026 - **Apply:** https://blueorigin.wd5.myworkdayjobs.com/BlueOrigin/job/Denver-CO/Senior-Engineer--Compute-Fabric---Network-Architecture--Project-Sunrise_R73610 ## About the Role * Bachelor of Science in Computer Science, Electrical Engineering, or a related field. * 8+ years of experience in HPC networking, datacenter fabric design, or GPU cluster engineering. * Demonstrated expertise in designing and deploying large-scale accelerator clusters using high-speed, direct GPU-to-GPU interconnects and high-radix fabric switches. * Deep, hands-on experience with network topology at scale (e.g., large supercomputer clusters or hyperscale infrastructure) and associated fabric management tools. * Proficiency with collective communication libraries. * Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum., * Master's or Ph.D. in a relevant discipline. * 10-15+ years of experience in a senior networking or systems design role. * Extensive experience with InfiniBand fabrics. * Intellectual curiosity and a first-principles approach to problem-solving, particularly for novel challenges like the effect of radiation on network switch silicon (prior space experience is not required). * Experience at a major cloud provider (e.g., Meta, Google, Microsoft), HPC vendor, or National Laboratory (e.g., ORNL, ANL, LLNL) focused on large-scale GPU networking. * Passion for and understanding of AI and Machine Learning applications in engineering, with a demonstrated ability to learn and integrate new technologies. ## Description Our team is developing next-generation spacecraft that push the boundaries of performance and capability in orbit. We are building a large-scale orbital data center, and we are looking for a hardware-leaning systems engineer to be the architect and builder of its nervous system. This is not an operator role; you will be the owner responsible for making the foundational hardware decisions for our high-speed interconnect fabric and owning its performance from the physical layer all the way up to the software stack. You will solve novel, first-principles challenges, such as ensuring fabric resiliency in a radiation environment, and your decisions will be critical to the success of the entire program., * Architect the hierarchical GPU interconnect topology for a large-scale accelerator cluster, defining pod architecture, fabric switch placement, and inter-pod fabric selection. * Following hardware selection, own the configuration, bring-up, and operation of fabric management software, defining topology files and partitioning policies for multi-tenant workloads. * Lead the hardware qualification of fabric switches and other network components for the space environment, developing novel strategies to mitigate radiation effects on switch state and routing tables. * Take ownership of the collective communications performance across the fabric, tuning libraries (e.g., NCCL, RCCL) and defining the bandwidth/latency budgets required for high-performance model-parallel inference. * Collaborate deeply with software teams to co-design the fabric topology with model parallelism strategies, ensuring optimal performance for large-scale AI models. * Interface with platform software teams to manage the fabric software bring-up and integration process., Applicants for employment at Blue Origin must be a U.S. citizen or national, U.S. permanent resident (i.e. current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. Background Check * Required for all positions: Blue's Standard Background Check * Required for Certain Job Profiles: Defense Biometric Identification System (DBIDS) background check if at any time the role requires one to be on a military installation * Required for Certain Job Profiles: Drivers who operate Commercial Motor Vehicles with a Gross Vehicle Weight (GVW), Gross Vehicle Weight Rating (GVWR) or combination of power unit and trailer that meets or exceeds 10,001 lbs. and/or transports placardable amounts of hazardous materials by ground in any vehicle on a public road while in commerce, may be subject to additional Federal Motor Carrier Safety Regulations including: Driver Qualification Files, Medical Certification (obtained before onboarding), Road Test, Hours of Service, Drug and Alcohol Testing, vehicle inspection requirements, CDL requirements (if applicable) and hazardous materials transportation/shipping training. * Required for certain Job Profiles: Ability to obtain and maintain Merchant Mariner Credential, which includes pre-employment and random drug testing as well as DOT physical
