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.
