Overview

Senior Full-Stack Blockchain Engineer (5+ Years Experience) – Location: Remote (Flexible) – Type: Full-time

About the Role

We are seeking a highly skilled Full-Stack Blockchain Engineer with ~5 years of professional experience to design and build scalable, production-ready Web3 applications. The ideal candidate has strong expertise in smart contract development, distributed systems, and cloud-native architectures, combined with hands-on experience in modern web technologies for seamless user-facing experiences.

You will play a key role in building decentralized applications, integrating cross-chain solutions, and developing high-performance backends and responsive frontends. If you’re passionate about blockchain protocols, scalable systems, and creating impactful user-first products, this is the role for you.

Responsibilities

• Design, develop, and optimize smart contracts (Solidity, Rust) with a focus on security, performance, and scalability.
• Build and maintain full-stack dApps integrating Web3 APIs, wallet providers, and protocol SDKs.
• Develop backend microservices (Node.js, Go, or Python) supporting real-time blockchain data, event-driven architectures, and API gateways (REST/GraphQL).
• Architect scalable cloud-native systems using Docker, Kubernetes, and AWS/GCP services.
• Implement cross-chain interoperability solutions, decentralized storage integrations (IPFS/Arweave), and event-driven pipelines (Kafka, WebSockets).
• Collaborate with product and design teams to deliver polished React/Next.js or Angular frontends with TypeScript and Tailwind CSS.
• Contribute to testing, auditing, and deployment pipelines to ensure reliability, maintainability, and security.

Requirements

• 5+ years of professional software engineering experience with at least 3 years in blockchain/Web3 development.
• Strong proficiency in Solidity and/or Rust for smart contract development (EVM-compatible or WASM-based).
• Experience with Node.js, Go, or Python for backend services and APIs.
• Proficiency in React/Next.js or Angular for frontend development with TypeScript.
• Familiarity with cloud infrastructure (AWS, GCP, Docker, Kubernetes) and CI/CD pipelines.
• Knowledge of decentralized storage (IPFS, Arweave) and indexing solutions (The Graph).
• Understanding of event-driven systems, distributed architectures, and real-time data flows.
• Strong problem-solving skills and ability to work in a collaborative, fast-paced environment.

Nice to Have

• Experience with cross-chain bridges, Layer-2 solutions, or rollups.
• Knowledge of smart contract auditing tools and security best practices.
• Familiarity with fuzz testing, property-based testing, or blockchain-specific test frameworks.
• Contributions to open-source Web3 projects.

What We Offer

• Competitive compensation package (salary + tokens/equity opportunities).
• Flexible remote-first culture.
• Opportunity to work on cutting-edge blockchain protocols and decentralized platforms.
• Growth-focused environment with mentorship and continuous learning.

Job Specification

• Proficiency in full-stack development (JavaScript, Node.js, React, etc.).
• Strong experience in blockchain technologies (Ethereum, Smart Contracts, etc.).
• Familiarity with decentralized applications (dApps).
• Understanding of cryptocurrency and digital asset management.
• Excellent problem-solving skills and attention to detail.
• Experience with cloud services (AWS, Azure) is a plus.
