At Oku, we aim to close the gap between the CeFi and DeFi trading experiences. It is no mistake that 95% of crypto trading occurs on centralized platforms like Binance and Coinbase since their organizations have spent substantially more time and resources investing in their trading interface, while DeFi has primarily been focused on infrastructure and protocols for the last several years.
However, that is going to change soon. While CeFi organizations enjoy their Web2 stack, a Web3 company like Oku can leverage the composability of the DeFi ecosystem and blockchain technology to offer a high-quality trading experience that will eventually be indistinguishable from CeFi and, in the long run, overcome their legacy systems. That is why Oku has 50+ partners in or supporting the app.
Oku initially started as a project within GFX Labs after they received a $1.6M grant from the Uniswap Foundation in October 2022 to build and launch a reimagined trading interface, analytics platform, and API for Uniswap v3. After ten months of development, Oku launched in July 2023, and since then, Oku has supported the DAO Uniswap’s efforts to expand across new blockchains.
Today, our primary feature is our smart order routing system, which integrates 12+ order routing systems to ensure all users find the best price possible. We have also adapted our order routing technology to offer a bridge aggregator with 11+ integrated bridges. Most recently, to close the CeFi/DeFi gap further, we added on/off-ramping with USD and EURO to our interface at an industry-low fee of free! Our other popular features include trustless onchain limit orders built directly on Uniswap v3, our position manager page for users who want to manage their LP positions, and our Uniswap v3 analytics.
Over the coming years, Oku will be expanding the scope of our offering and improving the quality of our user experience.
As a Web3 Frontend Engineer at Oku, you’ll be handling web3 data and functions to bring them neatly into Oku. You will work closely with the entire team, but particularly our product designers and the other frontend engineers.

At Coinbase, our mission is to increase economic freedom in the world. It’s a massive, ambitious opportunity that demands the best of us, every day, as we build the emerging onchain platform — and with it, the future global financial system.
To achieve our mission, we’re seeking a very specific candidate. We want someone who is passionate about our mission and who believes in the power of crypto and blockchain technology to update the financial system. We want someone who is eager to leave their mark on the world, who relishes the pressure and privilege of working with high caliber colleagues, and who actively seeks feedback to keep leveling up. We want someone who will run towards, not away from, solving the company’s hardest problems.
Our work culture is intense and isn’t for everyone. But if you want to build the future alongside others who excel in their disciplines and expect the same from you, there’s no better place to be.
While many roles at Coinbase are remote-first, we are not remote-only. In-person participation is required throughout the year. Team and company-wide offsites are held multiple times annually to foster collaboration, connection, and alignment. Attendance is expected and fully supported.
Developer Experience (DevX) is responsible for making sure all engineers at Coinbase build high-quality products while being productive and engaged. We do this by providing infrastructure, libraries, frameworks, and tooling to make it easier and faster to build high quality applications. Within DevX, our Onchain Pod is focused on defining the future of developer experience for onchain developers, both within Coinbase and in the broader crypto ecosystem. We believe that the onchain platform is the most important builder platform since the internet (“online”). As a Staff Software Engineer on this team, you’ll be instrumental in designing, building, and executing core solutions that drive our systems.
