Platform Architect

Skills

About the Role

You will define and evolve the architectural foundation of core platforms and shared services. You will design scalable, secure, and fault-tolerant distributed systems that support Bitcoin, Layer-2, and enterprise products. You will set platform standards for APIs, data models, service boundaries, and infrastructure patterns. You will partner with engineering teams to guide implementation, review designs, and resolve complex technical challenges. You will collaborate with security and infrastructure teams to ensure defense-in-depth, key management, and operational resilience. You will evaluate and introduce new technologies while balancing innovation with operational maturity. You will document architectural decisions, tradeoffs, and long-term technical roadmaps. You will mentor senior engineers and raise architectural rigor across teams.

Requirements

• 5+ years designing and operating large-scale platforms or infrastructure systems
• 6-8 years building production-grade backend systems with strong security boundaries, authentication, authorization, key management, and designing APIs and data models for distributed services
• Proven experience as a Platform Architect, Principal Engineer, or Senior Systems Architect
• Deep understanding of distributed systems including consensus, fault tolerance, replication, and networking
• Strong experience with cloud and hybrid infrastructure such as AWS, GCP, bare metal, Kubernetes, and Terraform
• Expertise in security-critical systems including authentication, authorization, cryptography, and key management
• Experience designing high-availability systems for financial or mission-critical applications
• Strong written and verbal communication skills
• Comfort working in a remote, globally distributed team
• Hands-on experience with Bitcoin, Lightning, Liquid, or blockchain infrastructure (preferred)
• Experience contributing to open-source projects (preferred)
• Familiarity with HSMs, secure enclaves, or hardware-backed key storage (preferred)
• Background in fintech, capital markets, or institutional financial systems (preferred)
• Experience balancing enterprise requirements with decentralized architectures (preferred)

Responsibilities

• Own the architecture and technical vision for the platform and shared services
• Design scalable, secure, and fault-tolerant distributed systems supporting Bitcoin, Layer-2, and enterprise products
