<h2 id="about-gfx-labs">About GFX Labs</h2><p>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.</p><p>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.</p><p>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.</p><p>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.</p><p>Over the coming years, Oku will be expanding the scope of our offering and improving the quality of our user experience.</p><h2 id="why-work-at-oku">Why work at Oku?</h2><p>Any firm can pay a high salary and offer good incentives (as will we), but most can’t offer interesting, challenging, and rewarding work.</p><p>We have something to prove.

Founded in 2017, it is the world’s first open-source protocol for decentralized video streaming, built on Ethereum. The project has empowered developers to create scalable, cost-effective, and censorship-resistant video applications. The Livepeer network has transcoded billion of minutes, serving Web3 and Web2 platforms across gaming, entertainment, social media, and beyond. In 2024, Livepeer AI was introduced, unlocking Livepeer’s compute network for AI inference workflows. From real-time video transcription and object detection to scene recognition and AI-powered editing, Livepeer AI brings advanced machine learning directly into the decentralized video stack. These new tools not only reduce costs but also empower developers to build richer, smarter, and more engaging video experiences—whether for Web3 platforms, AI-powered dApps, or even traditional video use cases.</p><h2 id="your-role">Your Role:</h2><p>Livepeer AI is looking for an experienced, self-driven SRE Engineer – someone that loves to build tools automate everything and deliver the best production experiences for end users.
