We're always hiring software engineers for all of our offices. Technology is at the core of how we approach our work, and engineers are intimately involved in every area of the business.
We are big believers in functional programming and use OCaml, a statically typed functional programming language, as our primary tool. More recently, Python has become a vital part of Jane Street’s research and trading work, acting as the go-to language for data analysis, visualization, and machine learning.
We also believe in the value of open source software, using it in our daily work and releasing over a million lines of our own code as open source.
If you'd like to get an idea of what we cover in our software engineering interview process, you can visit our interview prep page.

We are looking for a FIX Onboarding and Connectivity Engineer to help us grow both our proprietary trading capabilities and client-facing trading business. This role involves working on the technical processes that enable our trading desks to access new products and exchanges, while also onboarding external clients to trade with Jane Street. You'll work closely with our trading teams to help them grow the business, and with our technology teams to build state-of-the-art connectivity systems.
Jane Street is a place where people come to learn new things (and to eventually teach others what they know). While we welcome experience with FIX and other order flow/electronic trading protocols, and value software engineering backgrounds, we're excited to teach you the specifics of our trading and technology.
The majority of your time will focus on onboarding and connectivity projects across both proprietary and client-facing trading. This will involve prioritising requests from the trading desks; working with our developers, infrastructure engineers, and external parties; and seeing the onboarding process all the way through to production. You will often find yourself bridging the gap between our clients, trading teams, and technology teams, requiring strong communication and coordination skills, but you will also need to be comfortable navigating the Unix command line and developing code of varying complexity to deliver these projects.
Through this work, we will expect you to keep a thoughtful and empathetic perspective on the way the team functions and collaborates as a whole, and to suggest ways we can improve and promote our best practices. We'll also look to you for opinions on how we approach and deliver project work, and how we should interface with other internal teams.

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’re looking for Software Engineers who want to help us design and build the systems and tools that run the firm. You’ll find Software Engineers in all parts of Jane Street, solving real problems in critical areas ranging from trading desks to our accounting team, as well as building foundational infrastructure, whether that means implementing network monitoring or risk models.
We are big believers in functional programming and, using OCaml, a statically -typed functional programming language, as our primary tool. More recently, Python has become a vital part of Jane Street’s research and trading work, acting as the go-to language for data analysis, visualization, and machine learning.
Beyond our own environment, we also recognize the value of open source software, leveraging it in our daily work and releasing over a million lines of our own code as open source. We’re also always looking for ways to expand open source projects, and provide ongoing support to things like Mercurial, the OCaml compiler, and the OPAM package manager. That said, we’re interested in talented engineers with experience in any language—most of us came in with little to no practical experience in OCaml before we joined.
If you’d like to learn more, you can read about our interview process and meet some of our newest hires.
We don’t expect you to have a background in functional programming, OCaml, Python, finance, or any other specific field—we’re looking for smart programmers who enjoy solving interesting problems. We’re more interested in how you think and learn than what you currently know. You should be:

We're looking to add a passionate Cybersecurity Analyst to our Hong Kong or Singapore office to help protect Jane Street’s employees, data and infrastructure from the wilds of the internet. Our cybersecurity analysts are responsible for developing and using monitoring tools to guard the firm, as well as handling incident response and remediation when a threat is found.
Our team considers itself to be tapped into the developments happening within the broader cybersecurity space, and able to tell the difference between the latest cool hack by security researchers and what actually matters in our day-to-day. In this role, you’ll carefully consider the context of our decisions as we think about the trade-offs we’re making in our approach to resolving cybersecurity issues.
We’ll expect you to apply a methodical approach to performing unstructured investigations to locate and repair the source of a security issue. While there will be an element of operational coverage, your time will also be spent on projects to improve our detection capabilities, automation and efficiencies, as well as performing threat hunts, allowing you to grow your skill set and impact.
You will also act as an ambassador of best practices to the rest of the firm. All of our team members understand and practise good personal cybersecurity hygiene, and are able to talk to others about it. A key component of doing well in this position is bringing everyone else along with you on the cybersecurity journey, and you should be excited to learn from your colleagues and pass that learning on to new analysts.
