We are looking for Linux Engineers to join the team that maintains the critical infrastructure underlying the rest of Jane Street’s technology. Our group includes hard-working Systems Engineers, Administrators and Programmers, tasked with maintaining and improving the platform that powers Jane Street's production trading systems. Our mix of in-house and open source software allows you to investigate and innovate at every level. On any given day, you could be debugging kernel performance, developing management tools, or resolving production issues in real time. Diving into tricky systems problems is our specialty.
Deployment automation, scalable configuration management, and obsessive monitoring are the focus of some of our ongoing projects. We automate as much of our work as we can, but not because we’re lazy. We find that automation reduces our error rate and overall workload - plus, we think it's fun.
Working in our group provides opportunities for involvement with almost every other facet of the company. We work directly with colleagues in trading, technology, and operations to build and maintain systems with a firm-wide scope. Using feedback from other groups and our custom monitoring tools, we strive to resolve production issues quickly, perform comprehensive root-cause analyses, and integrate long-term fixes in a clean and robust way.
We don't expect you to come in with deep experience - we're happy to hire smart problem solvers and teach them what they need to know. You’ll train alongside our more seasoned team members in a hands-on capacity, learning how we make tangible and immediate improvements to our infrastructure every day.

If you are imagining a daily routine that involves making copies and watching as someone turns a computer off and back on, think again: this is not your typical IT internship.
We will train you as if you’re joining our full-time team of IT Operations Engineers who are responsible for the support, configuration and operation of multiple systems across all of our technology stacks, including desktop engineering, network and various application platforms. You will help in a hands-on capacity as we make improvements to our office environment. This can include: responding to technology support requests, building and configuring Windows and Linux devices, supporting our Windows domain infrastructure, monitoring and supporting systems and helping with projects to optimize the way we work using tools like PowerShell.
Our IT interns are friendly and collaborative problem-solvers who enjoy helping people. They are able to troubleshoot in real time and engage with our end users, and are comfortable asking questions and admitting to mistakes. Our internships provide a great introduction to Jane Street and how we think about and solve problems across all teams. Often, successful interns have been invited to return for a full-time position after graduation.
We don’t expect you to have a background in finance or any other specific field—we’re more interested in how you think and learn than what you currently know. You should be:

Our goal is to give you a real sense of what it’s like to work at Jane Street full time. Over the course of your internship, you will explore ways to approach and solve exciting problems within your field of interest through fun and challenging classes, interactive sessions, and group discussions — and then you will have the chance to put those lessons to practical use.
As an intern, you are paired with full-time employees who act as mentors, collaborating with you on real-world projects we actually need done. When you’re not working on your project, you will have plenty of time to use our office amenities, physical and virtual educational resources, attend guest speakers and social events, and engage with the parts of our work that excite you the most.

As a Linux Engineering intern, you’ll work side by side with full-timers to learn how we maintain and improve the critical infrastructure underlying our firm’s technology, including our production trading systems. On any given day, we might be debugging kernel performance, developing management tools, or resolving production issues in real time. Our mix of in-house and open source software allows us to investigate and innovate at every level.
During the program you’ll work on up to two projects, mentored closely by the full-time employees who designed them. Some projects consider big-picture questions that we’re still trying to figure out, while others involve building something new. We will choose your projects so you’ll gain a better understanding of the wide range of problems we solve every day — from finding new and interesting ways to resolve production issues quickly, perform comprehensive root-cause analyses, and integrate long-term fixes in a clean and robust way.
You’ll have a unique opportunity to see how our team interacts with almost every other group, building solutions that work on a firm-wide scale. We automate as much of our work as we can, because we find that automation reduces our error rate and overall workload — plus, we think it's fun.
We don’t expect you to have a background in one specific field — we’re looking for smart people who enjoy solving interesting problems. We’re more interested in how you think and learn than what you currently know. You should be:

We are looking for a highly-driven Technical Program Manager who can provide organization and coordination support for our engineering initiatives. Technology is core to our business, and this role is an opportunity to work alongside our engineers as we build and optimize Jane Street’s trading technology.
You’ll draw from your technical background on a daily basis, leading projects through their entire lifecycle, including defining goals, developing timelines, tracking milestones, managing developer time, identifying risks, and coordinating with related teams. You’ll also communicate project schedules, priorities, and status updates to the larger organization.
Strong communication skills and the ability to manage competing priorities will be necessary to collaborate across a wide range of teams at Jane Street—including developers, business teams, operations, support—as well as with external financial entities, to make sure each project is delivered on time and meets or exceeds stated goals and expectations.
We operate in a flexible problem-solving environment that encourages people to think outside the box when developing processes and tools for the project at hand. The person in this role needs to be a strategic thinker who considers the goals of the group and project when problem solving.
This role sits within Jane Street’s technology group which designs, deploys, and supports all of the infrastructure that underpins our trading activities. The scope of our systems is large, and you'll gain insight into a broad cross section of the global market as you work to improve them. To succeed in this role, you must enjoy working independently on small teams, learning on the fly, and making decisions that have a real and immediate impact on the firm.
At Jane Street, the “P” in TPM can mean a lot of different things. Depending on the team, the person, and the circumstances, you may find yourself anywhere on the spectrum from Program Manager to Product Manager. As a result, you’ll be most successful at Jane Street if you’re comfortable with that sort of ambiguity, and happy to roll your sleeves up and dig into the problem at hand, bringing whatever relevant skills you have to bear, whether through large-scale program management and coordination, product vision, business context, or anything else. That’s also why you’ll find a second job posting for “Technical Product Manager” elsewhere on the site that looks just like this one —– feel free to apply to whichever you think fits your experience and interests better and we’ll make sure your profile ends up in the right pipeline.

We are looking for an Audio/Visual (AV) Engineer to design, implement, and support our robust and resilient AV infrastructure. Technology is a key component of Jane Street’s core business and our AV needs are evolving as we grow, from traditional conference rooms to sophisticated trading floor environments and hybrid collaboration spaces.
In this role, you will be responsible for all AV systems, collaboration platforms, and teleconferencing services, including complex event spaces (500+ person auditoriums), standard meeting rooms (4-50 person capacity), huddle spaces, trading floor communication systems, live event support, and digital signage/IPTV networks. You should be passionate about the AV technology space and eager to help solve business issues by researching, testing, and implementing cutting-edge technologies in a fast-paced financial environment.
The scope of this role is broad and will rely on you to act as a subject matter expert for AV systems, from maintaining and supporting our existing technologies to developing design standards for new and expanding spaces. You’ll be expected to provide exceptional technical support, whether during a field installation or while troubleshooting directly with end users. Our AV Engineers also coordinate closely with our Technology and Infrastructure teams during expansion projects to ensure the infrastructure needs of each project are met.
Our team is composed of AV generalists, and the expectation is that anyone can help across all of our “verticals” (builds, operations, event support). While this role will spend most time in the expansion/builds space, in order to be successful in the role, you will need to be comfortable with changing between focuses and providing support (operational or event) where needed.
