Blockchain Developer

Location: Dubai / London / Remote | Engagement: Full-time or project-based | Experience: 3+ years preferred | Reports to: Technology Lead / Founder
Build secure, practical blockchain capabilities for Kognitiv Academy, including verifiable learning credentials, digital achievements and integrations that improve learner trust and portability. This is an engineering role, not a token-speculation mandate.
What you will own

- Design, develop and maintain smart contracts, APIs and blockchain integrations where they provide genuine product value.

- Develop verifiable credentials, on-chain or cryptographically verifiable certificates and badge issuance workflows.

- Evaluate appropriate chains, standards and wallet experiences against cost, security, privacy and usability.

- Integrate blockchain services with the learner platform, identity and existing backend systems.

- Write tests, documentation, monitoring and deployment automation; manage secrets and key security correctly.

- Coordinate independent reviews or audits before any production smart-contract deployment.

- Work closely with product, engineering and regulatory advisers on data protection and user consent.

Required experience and capabilities

- 3+ years in software engineering with demonstrable production blockchain/Web3 experience.

- Strong knowledge of Solidity/EVM or a comparably relevant blockchain stack, secure API design and backend engineering.

- Understanding of cryptographic signing, wallet interaction, transaction lifecycle and security risks.

- Practical Git, CI/CD, testing, observability and technical documentation skills.

- Ability to explain architecture choices in plain business language.

Nice to have

- W3C Verifiable Credentials, Open Badges, decentralised identity and education credential systems.

- Experience with Ethereum-compatible L2s, indexers and cloud infrastructure.

- Prior work in education, gamification or SaaS.

First 90 days

- Audit current credential and gamification requirements and propose a minimal, secure technical architecture.

- Deliver a sandbox proof of concept for a verifiable credential or achievement workflow.

- Publish an implementation roadmap with costs, dependencies, security review and rollout gates.

Success measures

- Reliable and secure delivery against agreed milestones.

- Verification completion rate, integration reliability, test coverage and documented security findings.

- Low end-user friction and sustainable transaction/infrastructure cost.
