Senior Fullstack Engineer – React, NestJS, AWS

We're a growing tech startup building a customer-facing web platform and an internal AI model training platform. We're looking for a Senior Fullstack Engineer to join our engineering team and take real ownership of core systems.

This is a role for engineers — people who understand code deeply, think about architecture, and solve problems independently. Not someone who completes tasks, but someone who thinks about why they exist.

Responsibilities:

• Develop and maintain the full-stack platform (React frontend, NestJS backend, AWS infrastructure)

• Design and implement scalable backend services and APIs

• Work with Postgres RDS — design, optimize, and maintain relational data models

• Build and maintain event-driven services using SQS and microservices architecture

• Write unit and e2e tests (Vitest + Cypress) and maintain CI/CD pipelines (GitHub Actions)

• Write clean, modular code following SOLID principles

• Collaborate directly with Product to translate requirements into technical solutions

Requirements:

• Senior-level experience with React, NestJS, and TypeScript (frontend + backend)

• Hands-on experience with AWS (Lambda, EC2) and Docker

• Strong understanding of relational databases and Postgres

• Experience with microservices, event-driven architecture, and SQS

• Solid Git workflow and experience working in a team codebase

• Ability to read, understand, and improve unfamiliar code independently

• Clean code standards — SOLID, well-structured, maintainable

What We Value Most:

Independent thinking. We want engineers who trace problems to their root, understand the full flow of a system, and bring solutions — not just questions. If you read code before you Google, you'll fit right in.
