About the Position 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. About You Interested in learning about the microstructure of different exchanges and trading systems Proficient with coding; software engineering experience (building apps) highly valued Excellent coordinator and project management skills across multiple stakeholders Detail-oriented with clear written and verbal communication Able to learn new, complicated, and ever-changing systems Fluent in English 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.
