• Implement authentication and authorization using JWT and role-based access control with secure middleware patterns and OWASP-aligned input validation
• Integrate with EVM-based blockchain systems (Ethereum, Polygon, Arbitrum, Base), including wallet interactions, transaction lifecycle handling, and on-chain/off-chain reconciliation
• Deploy and operate services on AWS using Docker and CI/CD pipelines, with structured logging, monitoring, and on-call participation
• Write automated tests (unit, integration, end-to-end) using Jest, Mocha, Supertest, or similar frameworks
• Conduct code reviews, mentor mid-level engineers, and contribute to engineering documentation and best practices
• Collaborate with product, design, and engineering leadership across time zones to scope features, define API contracts, and deliver end-to-end

Qualifications & Experience

• 8+ years of full-stack development experience
• Strong expertise in MongoDB, Express.js, React.js, Node.js, and TypeScript across both client and server
• Experience designing and operating RESTful APIs and frontend integrations at scale

• Pagination, query optimization, and performance tuning
• Experience integrating with EVM-based blockchain systems (Ethereum, Polygon, Arbitrum, Base), including wallet interactions, transaction lifecycle handling, and on-chain/off-chain reconciliation
• Hands-on experience with AWS infrastructure (EC2, ECS, Lambda, S3, CloudWatch, IAM)
• Familiarity with Docker, GitHub Actions, and modern CI/CD workflows
• Experience writing automated tests across unit, integration, and end-to-end layers using Jest, Mocha, Supertest, Playwright, or Cypress
• Solid understanding of backend and frontend security practices
• Strong ownership mindset and accountability
• Ability to drive technical execution independently and mentor mid-level engineers
