Web3 Infrastructure Jobs in Switzerland, Europe

Blockstream was founded in 2014 by Dr. Adam Back and a group of cryptographers and engineers passionate about Bitcoin and its potential to transform financial infrastructure. Today, Blockstream builds secure Bitcoin and Layer-2 technologies used by banks, financial institutions, and enterprises worldwide.

We are seeking a Director, Platform & Integration Lead, a senior leadership role responsible for defining how client platforms are technically realized across systems, data environments, and Blockstream infrastructure.

This role operates in close partnership with the Director, Industry Lead, Financial Services, translating industry-specific solution strategies and reference architectures into scalable, production-ready platform implementations. While the Industry Lead defines what should be built and why based on market and client needs, the Platform & Integration Lead defines how those solutions are architected, integrated, and delivered at scale.

Acting as the bridge between the Head of Solutions and the Head of Delivery, this role ensures that architectural designs are executable, interoperable, and aligned with enterprise-grade integration standards.

• Establish and govern integration frameworks and reusable patterns aligned with industry reference architectures defined by the Industry Lead

• Guide engineering teams across:

  • DevOps, CI/CD, and deployment environments

  • System integration, testing, and validation

  • Platform scalability, reliability, and performance

• Act as the senior authority for cross-platform dependencies, integration decisions, and system-level trade-offs

• Ensure alignment between solution architecture (what is designed) and technical delivery (what is built and operated)
