Job description

We’re seeking a highly skilled Senior Fullstack Engineer with deep expertise in TypeScript, a strong preference for React on the frontend and NestJS on the backend, and rock-solid software-engineering fundamentals. You’ll balance frontend and backend work, contribute ideas when new technical challenges arise, and help deliver features quickly and reliably. Familiarity with AWS and modern event-driven patterns is valuable, but you won’t own infrastructure or DevOps pipelines.

Key Responsibilities:

• Design, develop, and maintain scalable fullstack applications using TypeScript (React + NestJS preferred).
• Comfortably tackle complex sprint tickets and help teammates unblock issues, delivering high-quality solutions efficiently.
• Propose and discuss technical approaches with the team when new problems surface.
• Collaborate closely with designers, product managers, and engineers to ship high-quality features.
• Write clean, testable, maintainable code and participate in code reviews.
• Deploy and troubleshoot applications in AWS-based environments.

Qualifications:

• 7+ years of professional experience across frontend and backend development.
• Advanced proficiency in TypeScript with significant React and NestJS experience.
• Strong foundations in design patterns, automated testing, clean architecture, and SOLID principles.
• Experience with relational databases (e.g., PostgreSQL) and ORMs such as Prisma or TypeORM.
• Practiced in writing and maintaining automated tests (e.g., Jest, Playwright, Cypress).
• Fluent English—clear, efficient verbal and written communication.
• Experience deploying applications to AWS and understanding common services (Lambda, S3, DynamoDB, API Gateway, IAM).
• Comfortable working in Agile environments, with a strong sense of ownership and accountability for quality and performance.

Preferred Qualifications:

• Familiarity with event-driven architectures, including tools and patterns such as Kafka / Amazon MSK, SNS + SQS fan-out, and Amazon EventBridge.
• Experience building microservices or modular monoliths and understanding their trade-offs.
• Familiarity with CI/CD pipelines (including GitHub Actions) and infrastructure-as-code tooling.
• Awareness of application-security best practices and performance tuning techniques.
• Experience with GraphQL, WebSockets, or other real-time communication patterns.
• Exposure to additional tech stacks and a demonstrated eagerness to learn new technologies quickly.
