Job Details

About the Position

We are looking for an experienced Data Center Mechanical Engineer who can help Jane Street shape how we approach cooling our data centers. It’s no small task—this critical role will directly support our data centers which powers our trading operations.

We are looking for someone with a deep understanding of the full data center infrastructure stack. We need someone who understands how a data center is designed, built, and used for the most demanding AI workloads. While we won’t ask you to be racking and stacking, we need you to have a deep familiarity of the work within the facility; a “jack of all trades” understanding up and down the technology and infrastructure stack from the power and cooling distribution to the chip level. You'll help us shape and support everything;  the operation, management, and monitoring of the thermal environment. 

You are going to bridge the gap between theory and practice – between our high-level thinking around strategic design and the practical conversations around compute and associated constraints with the physical infrastructure.

Responsibilities of the role will include:

  • Working closely with internal engineers as well as external vendors and consultants to design, implement, and monitor the operation of our data center power and cooling systems
  • Consulting internally with technology stakeholders to understand our compute needs and how they translate to our infrastructure needs
  • Develop and review design documentation, including cooling and power calculations, CFD studies, failure analysis, etc.
  • Work with our internal controls and monitor team to strategize on the control sequence of operation and monitoring approaches
  • Be able to abstract complex cooling constraints into clear, concise constraints for other technology teams to consume
  • Collaborate with other team members to research and develop future data center solutions that allow for maximum flexibility while maintaining the performance standards needed for our business
  • Building and leading an interdisciplinary team that includes ML researchers and engineers,  traders, data center and network architects and engineers, and facilities engineers
  • Bridging the knowledge gap between data center infrastructure and GPU/HPC systems to support our ML/compute cluster
  • Designing and overseeing the implementation of cooling systems for high-density GPU and trading systems

You’ll be based in New York but will support data centers in other areas, with a special focus on our ML and compute clusters. Travel to data center locations, along with other team members, would be required as needed. 

This is an exciting opportunity to help transform the way we think about power usage in our data centers and become an innovator in this space. There is a lot of open field here at Jane Street to build something truly exceptional—we are looking for someone who’s willing to dive in, harness our firm’s collective brainpower, and lead.

About You

We’re not sure the perfect list of skills exists for the person who will thrive in this role, but here are some of the things we’re looking for:

  • Mechanical, computer, or electrical engineering degree; the ability to work across hardware, mechanical, and data center engineering domains
  • 10+ years of experience in thermal/mechanical engineering or data center engineering
  • Direct experience with multi-megawatt GPU deployments and high-density computing environments
  • Hands-on experience working in data centers and a deep understanding of hardware engineering and data center operations
  • Strong project management skills
  • Ability to balance systems-level, operational thinking with practical engineering
  • Comfort with making decisions in the face of ambiguity and negotiating ideas across a diverse set of groups
  • Intellectual humility, curiosity, and a collaborative spirit
