About Tech Delivery

Tech Delivery is a leading IT cloud development partner focused on providing top-tier IT consultancy services and staff augmentation solutions for global clients. We specialize in cloud, Dev Ops, data, cybersecurity, and software engineering, building high-performance teams across LATAM, Europe and the US for mission-critical projects.

We are now looking for a Senior Blockchain Engineer with proven hands‑on experience in Amazon Managed Blockchain (AMB) using Hyperledger Fabric, to support one of our key enterprise clients.

In this role, you will be responsible for designing, deploying, operating and integrating Hyperledger Fabric networks on Amazon Managed Blockchain (AMB).

This is not a generic blockchain role: we require real, production‑grade experience specifically with Fabric on AMB, including automation, security, monitoring and integrations with AWS services.

You will work closely with client architects, security teams and application teams to build a robust, secure and maintainable enterprise blockchain platform.

• Design Hyperledger Fabric network topologies on Amazon Managed Blockchain: MSP and organization setup, channels and ordering service configuration (RAFT / Solo where applicable), endorsement policies and access models.
• Define governance, lifecycle and best practices for multi‑organization Fabric environments.

• Provision, configure and manage Fabric networks on AMB (peers, orderers, chaincode lifecycle).
• Configure and operate Fabric CA, MSPs and identity lifecycle (enrollment, revocation, certificate renewal).
• Handle network evolution: configuration updates, upgrades and scaling.

• Integrate AMB/Fabric with AWS core services, including VPC, subnets, security groups, Private Link, IAM roles and policies, KMS for key management, S3 for storage, backups and artifacts, Cloud Watch for logs, metrics and dashboards.
• Define secure connectivity patterns for client applications and external systems consuming the Fabric network.

• Implement Infrastructure‑as‑Code for AMB and related infrastructure using Cloud Formation, AWS CDK or Terraform.
• Standardize and automate network creation, scaling, configuration and teardown.

• Design and implement CI/CD pipelines to build, test and deploy chaincode, as well as to apply Fabric network updates.
• Define dev/test environments and workflows for Fabric (development, staging, production).

• Monitor Fabric networks on AMB: performance, latency, block/transaction throughput, ledger size.
• Implement alerting and health checks; troubleshoot network, chaincode and integration issues.
• Plan and implement backup/restore and disaster recovery strategies.

• Apply security best practices for Fabric on AMB: certificate rotation and identity hygiene, least‑privilege IAM, data protection in transit and at rest.
• Configure audit logging and traceability for transactions and administrative actions.

• Support application teams using Fabric SDKs (Node/Java) and common integration patterns.
• Collaborate with teams building APIs, microservices and event‑driven components that interact with the Fabric network.

• 7+ years of experience in blockchain platforms, with a strong focus on Hyperledger Fabric.
• Proven, hands‑on experience running Fabric networks on Amazon Managed Blockchain (AMB) (must‑have).
• Solid understanding of Fabric network topology (organizations/MSPs, channels, orderers, endorsement policies).
• Fabric CA, MSP configuration and identity lifecycle.
• Strong experience with AWS networking and security (VPC, Private Link, security groups, IAM, KMS).
• Hands‑on experience with Infrastructure‑as‑Code…
