blockstream - Platform Architect
Requirements
• Own the architecture and technical vision for Blockstream’s platform and shared services. • Design scalable, secure, and fault-tolerant distributed systems supporting Bitcoin, Layer-2, and enterprise products. • Define platform standards for APIs, data models, service boundaries, and infrastructure patterns. • Partner with engineering teams to guide implementation, review designs, and resolve complex technical challenges. • Collaborate with Security and Infrastructure teams to ensure defense-in-depth, key management, and operational resilience. • Evaluate and introduce new technologies while balancing innovation with operational maturity. • Ensure platform designs support regulatory, enterprise, and institutional requirements without compromising decentralization principles. • Document architectural decisions, tradeoffs, and long-term technical roadmaps. • Mentor senior engineers to raise the overall architectural rigor across teams. • Required Qualifications (bullet points): • 5+ years of experience designing and operating large-scale platforms or infrastructure systems. • 6-8 years of development experience building production-grade backend with strong security boundaries, authentication, authorization, key management, as well as designing APIs, data models, and distributed services that run reliably at scale. • Proven experience as a Platform Architect, Principal Engineer, or Senior Systems Architect. • Deep understanding of distributed systems, including consensus, fault tolerance, replication, and networking. • Expertise in security-critical systems with knowledge of authentication, authorization, cryptography, and key management. • Experience designing high-availability systems for financial or mission-critical applications.
