Principal Engineer, CoinDesk Data Engineering

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 the Bullish 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. 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 high‑performance infrastructure that powers the world’s most trusted crypto market data, architecting resilient systems that process over 26 billion monthly requests for real‑time market information. Our technical scope is expansive, encompassing the automated extraction and normalisation of data from global exchanges to be served via high‑throughput REST APIs, WebSocket streaming and direct client deliveries. We operate with a high degree of ownership over mission‑critical infrastructure, calculating the flagship indices that power some of the largest ETFs on the market while bridging the gap between creative freedom 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.

What You’ll Do

• Develop and champion a cohesive long‑term technical roadmap that elevates our existing services (internal & external REST streaming) toward a unified and scalable architectural vision.
• Lead the design of resilient high‑throughput systems ensuring new solutions are not only robust and secure but also set the standard for future development across teams.
• Act as the technical point person for our most complex cross‑team challenges such as ensuring data resiliency, uptime or evolving our client‑facing infrastructure without service interruption.
• Mentor senior engineers on advanced architectural patterns, trade‑off analysis and operational best practices, fostering a culture of technical curiosity and ownership.
• Identify and lead engineering‑wide improvements in areas like observability, developer tooling and testing strategies to increase performance and reliability across all services.

What You’ll Bring

• Principal‑level experience: 8 years in backend development with a proven track record in a Staff Principal or equivalent technical leadership role where you were responsible for the technical direction of multiple services.
• Expertise in distributed systems: deep hands‑on experience designing, building and operating complex, large‑scale distributed systems. Specific experience with both synchronous (e.g. REST APIs) and asynchronous (e.g. WebSockets, message queues like Kafka or RabbitMQ, event streams) communication patterns.
• Operational resilience: experience with high‑availability or sophisticated disaster‑recovery strategies for global 24/7 financial systems.
• Pragmatic polyglot: demonstrated ability to effectively use multiple languages in production environments (proficiency in Go or another language) and the expertise to choose the right technology for the problem at hand.
• Strategic buy‑vs‑build: lead the evaluation of third‑party vendors versus internal builds for core data infrastructure to ensure cost‑efficiency and performance.
• Data‑intensive application expertise: strong practical experience with modern databases (e.g. Redis, PostgreSQL) including schema design, query optimisation and performance tuning for high‑throughput workloads.
• Full‑lifecycle ownership: a strong DevSecOps mindset with expertise in building and maintaining CI/CD pipelines, infrastructure‑as‑code and robust observability (monitoring, logging, tracing) for production systems.
• Quality as a feature: a deep commitment to quality demonstrated by implementing comprehensive testing strategies (unit, integration, end‑to‑end, performance) that ensure system reliability.
• Influence and collaboration: exceptional communication skills with the proven ability to influence technical and non‑technical stakeholders, articulate complex architectural decisions and build consensus across multiple teams.
