About the position We are hiring Production Engineers in our New York 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 th at 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. If you'd like to learn more, you can read about Production Engineering at Jane Street . 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 If you're a recruiting agency and want to partner with us, please reach out to agency-partnerships@janestreet.com .

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
