About The Position

CoinDesk is the most trusted media, events, indices and data company for the global crypto economy. Since 2013, CoinDesk Media has led the story of the future of money and investing, illuminating the transformation in society and culture that comes with it. Our award-winning team of journalists delivers news and unparalleled insights that bring transparency, comprehension and context. CoinDesk Events gathers the global crypto, blockchain and Web3 communities at annual events such as Consensus, the world’s largest and longest-running crypto festival. CoinDesk Indices offers expertise in digital asset indices, data and research to educate and empower investors. In November 2023, CoinDesk was acquired by the Bullish group, owner of Bullish, a regulated, digital assets exchange. CoinDesk operates as an independent subsidiary with an editorial committee to protect journalistic independence. At Bullish, we are engineering the institutional standard for the digital asset industry. Our mission is to build a platform centered on security and compliance, requiring a commitment to technical excellence that extends beyond delivering code. As a global organization, we set a high bar for those driven to do their best work alongside experienced, deeply specialized peers. Engineers here treat development as a craft and own the outcome from concept to deployment. Our teams bring structure to ambiguity and shape the frameworks that support a global organization. We refuse to compromise on quality and seek problem solvers who thrive on complex technical challenges with real market consequences. The Bullish Treasury (BTH) Engineering team develops the foundational infrastructure that powers the secure management and rapid expansion of our digital asset ecosystem. As stewards of the firm's digital treasury, we ensure every transaction is meticulously safeguarded through rigorous custody protocols, advanced vault architectures, and strict authorization rules. Our engineers tackle complex on-chain challenges to build automated DeFi workflows, resilient privacy structures, and transparent, real-time financial intelligence dashboards. By solving intricate blockchain integration problems with cutting-edge tooling, we deliver the operational rigor required to navigate decentralized markets and provide total data integrity from institutional exchange accounts to comprehensive treasury analytics.
