Blockchain/AI Engineer
--Coimbatore, Tamilnadu--
Nio drives digital transformation for enterprises globally using AI, Odoo and Nio Insight (our core financial and compliance software). With a market footprint spanning the US, UK, Panama and the Caribbean, we are hiring for our world-class engineering hub in Coimbatore.
We are looking for a Blockchain & AI Engineer with 2-5 years of experience to join our engineering team in Coimbatore. You will work across both smart contract development and applied AI/ML, helping us design, build, and ship production systems that combine blockchain infrastructure with intelligent automation. This is a hands-on role with broad scope and room to grow.
Responsibilities
- Design, develop, test, and deploy smart contracts on EVM-compatible chains.
- Build and integrate AI/ML services — from data pipelines through model training to deployment — that work alongside on-chain components.
- Develop backend services and APIs that bridge smart contracts, AI models, and end-user applications.
- Write robust unit and integration tests, and contribute to code reviews and engineering documentation.
- Investigate and apply emerging tools and techniques across the blockchain and AI ecosystems.
- Collaborate with product, design, and senior engineers to translate requirements into working systems.
- Help maintain security best practices across both smart contracts and AI components.
Requirements
- 2-5 years of professional software engineering experience.
- Hands-on experience writing and deploying Solidity smart contracts using Hardhat, Foundry, or Truffle.
- Strong proficiency in at least one general-purpose language: Python, JavaScript / TypeScript, or Go.
- Practical experience building or integrating ML or AI components in production — not just notebooks. Familiarity with PyTorch, TensorFlow, scikit-learn, or modern LLM tooling.
- Solid backend fundamentals: REST APIs, relational databases, version control (Git), and standard CI/CD workflows.
- Good understanding of how blockchains, wallets, transactions, and common token standards (ERC-20, ERC-721) work.
- Awareness of common smart contract security pitfalls and mitigations.
- Strong problem-solving skills and clear written and verbal communication in English.
Nice to have
- Experience with Web3 libraries such as ethers.js, viem, or web3.py.
- Exposure to L2 networks (Polygon, Arbitrum, Optimism, Base) or non-EVM chains.
- Familiarity with oracles (Chainlink, Pyth), IPFS, or off-chain compute frameworks.
- Experience with LLM application development — prompt engineering, RAG, vector databases, agent frameworks.
- Exposure to MLOps tooling (MLflow, Weights & Biases, SageMaker, Vertex AI).
- Cloud experience with AWS, GCP, or Azure.
- Open-source contributions, hackathon entries, or personal projects in blockchain or AI.
- Interest in real-world asset (RWA) tokenisation, DeFi, or regulated blockchain applications.
What's great in the job?
- Great team of smart people, in a friendly and open culture
- No dumb managers, no stupid tools to use, no rigid working hours
- No waste of time in enterprise processes, real responsibilities and autonomy
- Expand your knowledge of various business industries
- Create content that will help our users on a daily basis
- Real responsibilities and challenges in a fast evolving company
