About the Position

We are looking for an Interior Designer to help us create beautiful, innovative and functional spaces that reflect the culture of Jane Street. 

Jane Street’s culture is open, collaborative and intellectually curious. We love patterns, puzzles, and creative callouts to math and science concepts in our space, and we’re looking for someone who can work with various teams across our firm to find inspiration and translate these types of concepts throughout our architecture and design. 

You’ll work closely with our Creative Engagement team but sit full-time on Engineering, giving you the opportunity to shape creative ideas from the earliest stages of a project. A big part of success in this role will be understanding what shapes our culture and how we like to use our spaces. Your daily work will include:

• Collaborating and project managing other internal teams to identify project goals and requirements and develop sketches, models, and/or renderings to develop design direction
• Creating timelines, selecting and managing vendors, reviewing proposals and estimates, tracking milestones, confirming materials, coordinating installations and reviewing for errors
• Wayfinding to ensure that our spaces are intuitive and easy to navigate
• Managing space planning, layout, and the use of new and existing furniture, furnishings, and décor (based on our inventory and usage rates)
• Thinking about the nuances of our spaces and how things should be staged, both for our ongoing office environment and for special programmes and recruiting events
• Tracking what works best in what spaces and for what purposes, along with what does not work and should be avoided in the future
• Staying at the cutting edge of furniture innovation and updating the team on what’s new in the market and what showrooms and conventions we should be attending  
• Overseeing our furniture punch list and improving the process where possible
• Producing furniture specification packages for distributors, reviewing procurement from the bids and levelling, and providing budget figures with lead times during the design.

Historically these responsibilities were spread out across multiple people at the firm, but as our teams and spaces continue to grow, we need someone dedicated exclusively to these efforts.

About You

• Have 5+ years of experience managing interior design projects in corporate spaces; and experience with commercial interiors, hospitality, and/or retail architecture  
• Have a personal network of trusted external contractors and industry contacts, including fabricators and furniture vendors
• Highly organised with excellent time management skills
• Can communicate clearly with colleagues and external partners; comfortable asking for feedback and moving projects in different creative directions
• Confident working with brand elements, colour and materials and able to communicate a point of view about how they are applied
• Have a portfolio that demonstrates strong concept development executed to completion
• Proficient in AutoCAD, Bluebeam Revu, Illustrator, SketchUp, Rhino or similar software
• Fluent in English

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
