Role Overview:
Tamnoon is building software that helps teams streamline and scale cloud security remediation. As a Full Stack Engineer, you'll design, develop, and maintain secure, reliable, high-performing web applications—working across the stack with a strong emphasis on React + TypeScript (and Nest.js is a big plus). You'll collaborate closely with Product, Design, and Engineering to ship customer-facing features, iterate quickly, and continuously improve quality over time.
Requirements
What you'll get to do:
Build end-to-end product features using TypeScript, React, and Node.js—from UI to APIs to production-ready releases
Translate UI/UX designs into pixel-perfect, accessible, responsive components, ensuring a polished customer experience
Develop and consume RESTful APIs to enable smooth integration between front-end and back-end systems
Ensure strong integration, data integrity, and security across the application stack
Identify and resolve performance, reliability, and UX issues, balancing robustness with time-to-market and improving iteratively
Write and maintain tests (unit, integration, and end-to-end) using tools like Vitest, Mocha/Chai, or Playwright
Participate in code reviews and technical discussions, contributing to architecture decisions and better engineering practices
Own deployed code: monitor production behavior, investigate issues, and drive remediation.
Support CI/CD workflows including automated testing and deployment processes to keep delivery reliable and repeatable
Communicate clearly about trade-offs, design decisions, and implementation plans with teammates across varying technical backgrounds.
