Freedom to design the best platform available, with direct access to users to build what they need. Most Hedge Funds, Banks and Trading Firms have all kinds of legacy platforms at the heart of their operations, typically meaning only small new features can be added to their platform. Here, you're going to get more of a “blank canvas”, and certainly much more free reign to use the right tools for right project. The ownership here will very likely be a step-up for you. Yes, there will be challenges with working in a lean, agile team, but nothing is set in stone, and you'll have lots of chance to make your mark across the business. You will be working across the full stack; whether it's enhancing the OMS integration, building a brand new UI visualisation for trading results or web application APIs, your impact will be vast here. Tech wise, we're looking for a Polyglot Engineer that is true to the name; the stack is Python for Data, Javascript / frontend and Elixir / web, but there's a firm belief here that a capable engineer with the right mindset can pick anything up quickly. Ideally you'll come from a fund / capital markets, but certainly good financial markets / domain experience. This is a multistrat fund, and so a varied asset class background would be great - the sweet spot would be someone with a few years of relevant commercial experience here. You can expect to be compensated well; up to $400k total compensation is achievable. Want to build applications across the whole trading lifecycle and work directly with the COO of a fund?
