As we continue building high-growth digital products, we are expanding our engineering team with a Fullstack Engineer who can contribute across backend, frontend, infrastructure, and product development.

The Role

As a Fullstack Engineer, you will work closely with Product, Design, Mobile, and Business Intelligence teams to build fast, scalable, and reliable applications. You will take ownership from concept → architecture → implementation → deployment, playing a key role in delivering secure, high-performance services that power our mobile apps and internal products.

This position is ideal for someone who thrives in a fast-moving, entrepreneurial environment and enjoys working end-to-end across the stack.

• Design, build, and maintain scalable backend services using Node.js, NestJS, TypeScript, Prisma, and PostgreSQL.

• Develop responsive and high-quality frontend interfaces using Next.js, React, and TypeScript.

• Build and optimize APIs consumed by mobile clients (Flutter), ensuring performance, stability, and clean data structures.

• Own database design, schema migrations, indexing, and performance tuning.

• Implement robust authentication/authorization flows (JWT, OAuth).

• Write clean, maintainable, well-tested code (Jest, integration tests, API tests, E2E tests).

• Debug frontend and backend issues efficiently.

• Deploy and operate production services on AWS, with hands-on work in EKS, CI/CD, Helm, networking, and scaling.

• Work with containerized environments using Docker and contribute to IaC (Terraform or AWS CDK is a plus).

• Improve development workflows, performance, CI/CD pipelines, and monitoring.

• Collaborate closely with cross-functional stakeholders to ship high-impact features quickly.
