Identity & Access Blockchain Specialist

About the Role

Identity & Access Blockchain Specialist

Key Responsibilities

• Design and implement

  decentralized identity (DID)

  and

  self-sovereign identity (SSI)

  solutions using blockchain standards and protocols.
• Build or integrate identity frameworks such as

  W3C DIDs

  ,

  Verifiable Credentials (VCs)

  ,

  OAuth2

  ,

  OpenID Connect

  , and

  SAML

  with blockchain backends.
• Develop

  smart contracts

  to manage access control logic, permissions, roles, and credentials on-chain.
• Evaluate and work with

  blockchain identity platforms

  (e.g., Sovrin, uPort, Polygon ID, Civic, Dock, Ontology, Cheqd).
• Collaborate with product and engineering teams to design

  secure access flows

  across decentralized applications (dApps) and enterprise systems.
• Define and enforce

  privacy-preserving techniques

  using cryptography (e.g.,

  ZKPs

  ,

  selective disclosure

  ,

  hash commitments

  ).
• Ensure regulatory compliance with data privacy standards (e.g., GDPR, HIPAA) in identity architecture.
  
• Contribute to

  technical documentation

  ,

  whitepapers

  , and

  standardization efforts

  .
• Stay updated with emerging trends in decentralized identity, authentication, and blockchain IAM.

Required Skills & Qualifications

  ,

  OpenID Connect

  ,

  SAML

  ,

  JWT

• Smart contract development

  (Solidity, Rust, or DAML)

• Public key infrastructure (PKI)

  and digital signatures
• Hands-on experience with one or more blockchain identity platforms or protocols (e.g., Polygon ID, Hyperledger Indy/Aries, Dock, uPort, Ceramic, Spruce).
