Lead Engineer in London

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 CoinDesk, we do more than report on the future of money; we actively help shape it. As the global leader in crypto news, indices, and events, we provide the transparency and context the world needs to understand the digital asset revolution. Our team is dedicated to a shared mission of informing, educating, and connecting the global community. Our impact is further amplified by our position within the Bullish Group. Operating as a subsidiary of Bullish, a regulated, institutional-grade exchange known for its technological prowess, CoinDesk is powered by a partner that shares our fundamental belief in the transformative power of digital assets.

We value engineers who treat development as a craft and own the outcome from concept to deployment. You will be expected to navigate the unknown, bring structure to ambiguity, and help shape the frameworks and processes that drive our global teams forward. We refuse to compromise on quality and seek problem solvers who thrive on high-impact technical challenges.

The CoinDesk Data Engineering Team builds the infrastructure that powers global crypto market data. Our mission is to architect resilient systems that process tens of billions of monthly requests, managing the full lifecycle of data from global exchange ingestion to delivery via high-throughput APIs and streaming services. We own the mission-critical calculation engines for flagship indices backing major ETFs, bridging the gap between innovation and institutional-grade stability. As a core part of the global leader in crypto news and indices, our work provides the transparency and context necessary to help shape the future of money.
