Principal Engineer, CoinDesk Data Engineering

Director, Engineering, CoinDesk

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 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 normalization 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.

• Drive Technical Evolution: Develop and champion a cohesive, long-term technical roadmap that elevates our existing services (internal, external, REST, streaming) towards a unified and scalable architectural vision.
• Architect for the Future: 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.
• Tackle Foundational Challenges: 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.
• Elevate Engineering Excellence: Mentor senior engineers on advanced architectural patterns, trade-off analysis, and operational best practices, fostering a culture of technical curiosity and ownership.
• Champion Cross-Cutting Initiatives: Identify and lead engineering-wide improvements in areas like observability, developer tooling, and testing strategies to increase performance and reliability across all services.

• 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. You should have 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 (a proficiency in either Node.js or Golang) 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 optimization, 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.

• Cloud Architecture: Experience designing and deploying services on a major cloud provider (Azure, GCP).
• Blockchain Expertise: A strong understanding of blockchain technology, cryptocurrencies, and decentralized ecosystems is a significant plus.
• Financial Market Knowledge: Interest or prior experience in traditional financial markets, trading systems, or investment platforms.
• Containerization & Deployment: Proficiency with containerization technologies such as Docker or Kubernetes.
• Observability: Hands-on experience with modern observability tooling (e.g., Prometheus, DataDog, Jaeger, OpenTelemetry).
• Data Governance: Experience with data privacy (GDPR/CCPA) and security compliance in a regulated financial environment.
