About GFX Labs

Based in Chicago, GFX Labs is a research and development company founded in 2021, dedicated to pushing the boundaries of decentralized finance (DeFi). The company designs and builds cutting-edge tools and platforms for financial services, on-chain data integration, and professional trading experiences. Beyond product development, GFX Labs plays a key role in DeFi governance, contributing to the evolution of major blockchain protocols. With a mission to innovate and democratize finance, the company collaborates with regulators and industry leaders to shape the decentralized financial ecosystem. Its team of experts is committed to delivering impactful solutions for the future of blockchain-based finance.

GFX Labs operates two distinct divisions. Our primary division focuses on Oku, our comprehensive DeFi application. We have partnered with the Uniswap DAO, the leading decentralized exchange, and recently announced a collaboration with Morpho to integrate borrowing and lending into Oku.

Our second division is dedicated to research and development. This work spans various areas, including analyzing the economic safety of on-chain financial mechanisms, designing user experiences, and indexing data for integration into existing products. The GFX team possesses a wide range of skills and has a strong track record of delivering high-quality services to industry-leading organizations.

Why work at GFX?

• Any firm can pay a high salary and offer good incentives (as will we), but most can’t offer interesting, challenging, and rewarding work.
• We have something to prove. Our team is young and hungry. We like to move fast and make things. We know when to double down and when to cut our losses. We are going to make mistakes, and we are going to build a better product because of them. We don’t micromanage or have a huge team of product managers. We want self starters who take charge and solve problems.
• We don’t care if you went to school, what grades you got, or your age. Show us what you have built, what problems you have solved, and what skills you have.
