Blockchain & AI Infrastructure Engineer

ShiftX
Full-timeSri Lanka

An exciting opportunity to work on a cutting-edge Layer 1 blockchain protocol built from first principles, with native support for zero-knowledge cryptography, on-chain AI agents, and programmable financial infrastructure.

This role is ideal for engineers who are passionate about deep protocol development, privacy systems, and AI-integrated blockchain architectures. You’ll be part of a fast-moving, technically driven team focused on delivering high-impact infrastructure and tooling for next-generation financial systems.

Key Responsibilities

  • Develop and maintain core protocol components:
    • Zero-knowledge circuits (e.g., Circom, Cairo)
    • Virtual machine extensions and custom precompiles
    • Sequencer logic and runtime hooks
  • Design and implement AI-integrated logic
    • Model triggering and inference pipelines
    • Fraud detection using synthetic datasets
  • Build and maintain blockchain infrastructure tooling:
    • Validator management and delegation systems
    • Secure token distribution mechanisms (faucets)
    • Indexers, cross-chain bridges, and data services
  • Contribute to a custom blockchain explorer with staking, transaction analytics, and real-time data
  • Apply security-first principles in all code:
    • Signature schemes and zk-based privacy layers
    • Modular, audit-friendly architecture

Tech Stack & Tools

  • Languages: Rust, Go, Python, TypeScript, Solidity
  • zk Tooling: Circom, Halo2, ZKML frameworks (or similar)
  • DevOps/Infra: Docker, RPC infrastructure, custom indexers
  • Optional Plus: Experience with on-chain or hybrid AI model deployment

Ideal Candidate

  • Proficient in one or more core languages (Rust, Go, Python, or Solidity)
  • Familiar with zero-knowledge tools or motivated to dive deep into zk systems
  • Understanding of blockchain protocol architecture, node operation, and validator mechanics
  • Hands-on mindset with experience shipping production-grade tools or infrastructure
  • Comfortable working independently and collaboratively in a remote-first team

Nice to Have

  • Contributions to open-source blockchain or cryptography projects
  • Experience with synthetic data generation or AI inference logic
  • Interest in on-chain programmable finance and AI reasoning

What You’ll Gain

  • Opportunity to work on a technically ambitious Layer 1 with native AI + zk support
  • Exposure to deep protocol design and scalable infrastructure
  • Autonomy to own technical challenges end-to-end
  • A highly collaborative, execution-first engineering environment
