About the role

As a Quantitative Technologist, you will have holistic ownership over the firm's technical ecosystem. You will operate beyond the scope of a traditional developer, acting as an architect for mission-critical platforms that drive both our automated trading business and our commercial product suite. This role requires a mindset shift from "task execution" to "solution engineering." You will leverage the firm's deep market expertise to identify structural gaps in frontier market access-whether it be fragmented data, unreliable connectivity, or unique matching engine behaviors-and build sophisticated, reusable systems to solve them. We are looking for polyglot systems engineers who prioritize the right tool for the job. We prioritize architectural intuition and first-principles thinking over specific language trivia. We want engineers who understand the hardware-software interface and can adapt to new paradigms quickly. To apply, please submit your Resume/CV. We are also interested in seeing examples of complex systems you have built or open-source contributions that demonstrate your engineering philosophy.

Additional Information

Firm Overview K4 is a proprietary trading firm and technology provider operating at the intersection of quantitative finance and frontier markets. While many firms compete in established venues, K4 leverages deep domain expertise to systematize liquidity in complex, emerging, and idiosyncratic markets. At K4, research outcomes drive more than just risk-adjusted returns. We design and deploy the financial infrastructure that powers modern markets, partnering with leading research organizations to solve engineering problems at a global scale. We distinguish ourselves by building the "rails" for the world's most complex markets-creating a technological edge that is difficult to replicate.
