Key Responsibilities

• Create responsive, accessible user interfaces using React and Next.js, including complex forms, dashboards, and admin tools.
• Build and maintain backend services and APIs in TypeScript with robust input validation, authentication, and authorization.
• Ensure user-friendly loading, validation, and error handling with mechanisms to recover from interruptions and repeated requests.
• Manage shared packages and ensure consistency within npm monorepos.
• Integrate with external systems like CRM platforms, payment gateways, and electronic signature services.
• Develop webhook handlers that validate authenticity and manage event integrity.
• Construct asynchronous workflows using AWS Lambda and SQS, handling retries, partial failures, and synchronization with external platforms.
• Implement document processing and workflow states including approvals.
• Design and maintain PostgreSQL databases using Prisma, handle DynamoDB for application records, and use S3 for document storage.
• Ensure tenant isolation across databases, APIs, background jobs, and reports.
• Maintain data integrity with transactions, concurrency controls, and audit logging.
• Secure sensitive information such as credentials and personal data through proper configuration and logging.
• Deploy applications on AWS services including Lambda, SQS, S3, ECS, and Secrets Manager.
• Manage infrastructure with Terraform or AWS CDK, ensuring deployment impact is assessed and recovery plans are ready.
• Build Docker containerized applications and manage GitHub Actions CI/CD pipelines.
• Write automated tests, review code, document technical decisions, and troubleshoot production issues thoroughly.

Required Qualifications

• Proven track record of independently delivering and supporting production full stack applications.
• Expertise in TypeScript, React, Next.js App Router, and Node.js.
• Strong experience with PostgreSQL including schema design, migrations, and query optimization.
• Hands-on knowledge of AWS services, asynchronous processing patterns, and third-party API integrations.
• Practical experience with Docker, infrastructure as code tools, and CI/CD implementations.
• Good understanding of application security best practices, automated testing, and diagnosing production problems.
• Ability to translate business needs into dependable software solutions with minimal supervision.

Preferred Experience

• Familiarity with Prisma, Aurora PostgreSQL, and DynamoDB.
• Working knowledge of payment vaults and processors such as Evervault and Authorize.net.
• Experience with electronic signature platforms like DocuSeal.
• Design and maintenance of multi-tenant architectures with separate databases per organization.
• Knowledge of client certificates, mutual TLS, and device-based access control mechanisms.
• Experience implementing append-only audit models and workforce or document management systems.

Note: Familiarity with every preferred vendor is not mandatory; core skills are essential.

Ownership and Expectations

Candidates are expected to independently clarify ambiguous requirements, make implementation choices, raise significant risks with proposals, and take responsibility through deployment to resolving delivered functionality issues.

Interview Topics

Prepare to discuss a production feature you have developed that spans UI, API, and background processing layers, including your technical approach, failure handling, release strategies, and a production issue you have identified and fixed.

Eligibility

Applicants should hold a B.Tech or B.E. degree in Computer Science and Engineering, Electronics and Communication Engineering, Computer Science and Business Systems, or Information Technology.
