What are the key skills and qualifications needed to thrive as a Building Performance Engineer, and why are they important?

To thrive as a Building Performance Engineer, you need a solid background in mechanical or electrical engineering, building science, and energy modeling, often supported by a relevant engineering degree and certifications like LEED or CEM. Familiarity with energy modeling software (e.g., eQUEST, EnergyPlus), building automation systems, and simulation tools is typically required. Strong analytical thinking, problem-solving abilities, and effective communication skills set top performers apart in this role. These capabilities are essential for optimizing building efficiency, ensuring regulatory compliance, and delivering sustainable, cost-effective solutions.

What are some common challenges Building Performance Engineers face when working on projects with multidisciplinary teams?

Building Performance Engineers often collaborate with architects, HVAC specialists, and construction managers, which can present challenges in aligning energy efficiency goals with architectural design and budget constraints. Effective communication and negotiation skills are crucial to ensure that sustainability targets are integrated from the early design stages and maintained throughout the project. Navigating differing priorities and technical language among team members is a typical aspect of the role, but it also provides valuable opportunities for professional growth and learning.

What are Building Performance Engineers?

Building Performance Engineers are professionals who assess and optimize the efficiency, sustainability, and comfort of buildings. They analyze energy use, environmental impact, and indoor environmental quality, and recommend improvements to building systems such as heating, ventilation, air conditioning (HVAC), lighting, and insulation. Their goal is to ensure that buildings operate efficiently, meet regulatory standards, and provide healthy environments for occupants. They often use specialized software and conduct on-site evaluations to identify areas for improvement. Building Performance Engineers play a key role in green building initiatives and energy conservation efforts.

What is the difference between Building Performance Engineer vs Mechanical Engineer?

AspectBuilding Performance EngineerMechanical Engineer
CredentialsOften requires engineering degree, certifications like LEED or ASHRAETypically requires mechanical engineering degree, PE license often preferred
Work EnvironmentFocus on building systems, energy efficiency, sustainability projectsDesign, analyze, and maintain mechanical systems across various industries
Industry UsageCommon in green building, energy consulting, and building design firmsWidespread in manufacturing, HVAC, automotive, and industrial sectors

Building Performance Engineers specialize in optimizing building systems for energy efficiency and sustainability, often working closely with architects and environmental consultants. Mechanical Engineers have a broader scope, designing and maintaining mechanical systems across multiple industries. While both roles require engineering credentials, Building Performance Engineers focus more on building-specific projects, whereas Mechanical Engineers work on diverse mechanical systems.

Job Description:
We are seeking a highly talented and experienced Senior AI Fabric Performance Engineer to take on a critical role within our Performance Lab. In this high-impact position, you will drive the performance benchmarking of AI inference, training and storage workloads with focus on our network infrastructure. You will be responsible to generate reports that aid the customers in deployment and marketing team to position the product.
While the AI workloads (inference and training) run on our servers, your primary focus will be optimizing the Ethernet fabric that connects them. You will be responsible for executing rigorous performance benchmarks, isolating complex system bottlenecks, and tuning parameters to achieve maximum throughput and minimum latency. If you possess a deep understanding of Ethernet fabric, machine learning system demands, and Linux environments, and you thrive on solving complex performance puzzles, we want you on our team.
Key Responsibilities
  • Benchmarking & Execution: Install, configure, and run industry-standard AI performance benchmarks, with a strong emphasis on MLPerf (Training and Inference) and NCCL tests.
  • Fabric Optimization: Tune and optimize network parameters, focusing heavily on Ethernet fabric performance, to ensure seamless data flow for distributed AI workloads running on server clusters.
  • Deep Debugging: Identify, isolate, and troubleshoot complex system performance bottlenecks spanning across the Linux OS, server hardware, and Ethernet switches.
  • Automation Development: Design, develop, and implement robust performance testing frameworks and automation tools to streamline continuous benchmarking.
  • Cross-Functional Collaboration: Document test methodologies, communicate performance findings, and provide actionable improvement recommendations to hardware, software, and networking stakeholders.
Required Qualifications
  • Education: Bachelor's / Master's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical field plus 12+ years / 10+ years related industry experience.
  • OS Expertise: Deep familiarity and hands-on experience with Linux operating systems, including system-level performance tuning and troubleshooting.
  • Programming Skills: Strong proficiency in programming and scripting languages, specifically Python and C++.
  • AI/ML Knowledge: Familiarity with modern machine learning frameworks, particularly PyTorch, and a solid understanding of how AI models consume compute and network resources.
  • Networking & Fabric: Proven experience in performance testing and validating Ethernet switch systems.
  • Analytical Capabilities: Extensive experience with performance metrics, profiling, and benchmarking tools. Strong problem-solving skills with a proven ability to diagnose root causes in complex, distributed systems.
Preferred Qualifications (Optional but recommended for a critical role)
  • Experience with RDMA (Remote Direct Memory Access) and RoCEv2 (RDMA over Converged Ethernet).
  • Prior experience building CI/CD pipelines for automated hardware or software performance regression testing.
  • Familiarity with containerization and orchestration tools (Docker, Kubernetes) used in AI deployments.

Additional Job Description:
Compensation and Benefits
The annual base salary range for this position is $141,300 - $226,000.
