About the Position
We are hiring Production Engineers in our London office. Jane Street Production Engineers are software developers who spend time both developing software and also providing high-quality support for software systems that are critical to Jane Street's trading business.
Many of our Production Engineers are embedded in various software teams; others are in standalone teams. In both situations we work alongside application developers with a common goal of creating and running great software systems. As a firm we are big believers in functional programming, and use OCaml as our primary development language.
Production Engineers play an essential role interacting with a wide variety of departments and functions at Jane Street. We solve real-time issues and make a firm-wide impact. We take ownership of the architecture and design of systems that monitor and support the firm’s trading. We also design and develop the tools that we use, and it feels great to be able to shape these tools and then enjoy the improvements.

How is a Production Engineer role different from a generic Software Engineering role?
As Production Engineers:
- We split our time between OCaml software development project work and a support rotation, in which we actively resolve live issues in Jane Street’s critical systems
- We are curious and eager to learn about a number of different systems and how they fit together. This gives us a breadth of knowledge and opportunities to collaborate with many other dev and business teams across the firm
- We spend less time in total coding (due to the support rotation), and are interrupted more often, and we enjoy adding value to Jane Street in this way
- We get satisfaction from helping others, enabling good trades, and getting to the bottom of complex and urgent production issues
About You
We don’t expect you to have a background in functional programming, finance, or any other specific field—we’re looking for smart software developers who enjoy solving interesting problems. We’re more interested in how you think and learn than just what you currently know. You should be:
- A strong programmer with a love for technology; able to write and read code well
- An intellectually curious person who is motivated, collaborative, and eager to learn
- An excellent communicator, able to be clear and calm during production incidents
- Fluency in English required

What We Do
Jane Street works differently. As a liquidity provider and market maker, we trade on more than 200 trading venues across 45 countries and help form the backbone of global markets. Our approach is rooted in technology and rigorous quantitative analysis, but our success is driven by our people.
Our bright, beautiful offices in the heart of New York, London, Hong Kong, and Amsterdam are open and buzzing with conversation. We come from many backgrounds and encourage travel between offices to share perspectives. Some of our best ideas come from bumping into a visiting colleague at the office coffee bar.
Markets move fast. Staying competitive as we’ve grown has required constant invention—of new trading strategies, technology, and processes. We’ve found this is easier when you hire humble, kind people. They tend to help each other, and prioritize teamwork over titles.
We invest heavily in teaching and training. There’s a library and a classroom in every office, because deepening your understanding of something is considered real work. Guest lectures, classes, and conferences round out the intellectual exchanges that happen every day.
People grow into long careers at Jane Street because there are always new and interesting problems to solve, systems to build, and theories to test. More than twenty years after our founding, it still feels like we’re just getting started.
