IntellectEU is looking for a Blockchain Engineer to build a critical Key Management Service (KMS) driver, integrating Canton with Microsoft Azure’s Key Vault and Managed HSM. This role focuses on creating a secure, scalable component for cryptographic operations in production, requiring close collaboration with infrastructure and blockchain engineering teams.

What You'll Do

• Design, implement, and test a KMS integration layer between Canton and Azure Key Vault/Managed HSM to enable secure cryptographic signing and key usage.
• Collaborate with infrastructure teams to meet Canton’s protocol requirements for key custody, signing, and certificate validation.
• Develop reusable, well-tested libraries and ensure integration with deployment pipelines and secure CI/CD workflows.
• Participate in code reviews, threat modeling, and security audits to ensure high-quality, secure software delivery.
• Provide clear technical documentation and collaborate cross-functionally with product, DevOps, and architecture teams.

What We're Looking For

• Strong experience in Scala and/or Java, with demonstrated ability to write clean, maintainable, and secure code.
• Solid understanding of cryptographic fundamentals, including key lifecycle, secure storage, and secure computation.
• Familiarity with TLS, X.509 certificates, digital signature algorithms (e.g., ECDSA, EdDSA), and encryption workflows (AES, RSA, etc.).
• Experience building production-grade integrations, SDK wrappers, or plugins in distributed systems or blockchain platforms.
• Familiarity with REST/JSON APIs and asynchronous systems.
• Comfortable working in Git-based environments with modern CI/CD tooling.
• Upper-intermediate to fluent English (written & spoken) for effective technical communication.

Nice to Have

• Prior experience with blockchain or DLT platforms, particularly in enterprise use cases.
• Knowledge of Canton, Daml, or similar smart contract languages.
• Experience with Azure SDKs, especially for Key Vault and Managed HSM.
• Experience with AWS KMS, GCP KMS, or any HSM provider.
• Familiarity with secure software development practices (e.g., OWASP, threat modeling).
• Understanding of DevSecOps, including tools like HashiCorp Vault, secrets management, and security automation.
• Experience working with Kubernetes, Helm charts, and infrastructure automation (e.g., Terraform, Pulumi).
• Interest in financial infrastructure, custody platforms, or regulated systems.

Technical Stack

• Languages: Scala, Java
• Cloud & Services: Azure Key Vault, Azure Managed HSM
• Platforms: Canton, REST/JSON APIs, TLS, X.509
• Cryptography: ECDSA, EdDSA, AES, RSA
• Tools: Git, CI/CD
• Infrastructure: Kubernetes, Helm, Terraform, Pulumi, HashiCorp Vault

Benefits & Compensation
