Sr. Full-Stack Developer 🚀


About the Role

We are looking for a highly skilled Senior Full-Stack Developer to join our team and contribute to the development of scalable, high-performance web applications. You will be working for a client based in the US, helping to build innovative solutions in their product.


This role goes beyond execution. We’re looking for a product-minded engineer who can take ownership of features end-to-end, make pragmatic decisions, and move quickly from idea to production. If you are a self-driven professional with a strong problem-solving mindset and a deep understanding of modern full-stack development, this opportunity is for you.


What You'll Do

  • Build and maintain high-quality Angular applications, focusing on performance, usability, and rapid iteration.
  • Develop scalable APIs and service layers with NestJS, including auth flows, request orchestration, and async workflows.
  • Design and evolve modular architectures within an Nx monorepo.
  • Own features end-to-end contributing to both technical and product decisions.
  • Write clean, efficient code across the stack using TypeScript, JavaScript (ES8+), HTML5, and CSS3.
  • Ensure quality through TDD and automated testing, applying pragmatic tradeoffs when needed.
  • Collaborate with product and design to deliver production-ready solutions with speed and autonomy.
  • Contribute to code reviews, planning, and technical decision-making.
  • Leverage modern tools, including AI-assisted workflows, to iterate quickly.


What We're Looking For

  • 4+ years of experience in software development.
  • Strong proficiency in Angular (18+), NestJS, and modern JavaScript/TypeScript.
  • Solid understanding of scalable architectures (frontend & backend) and Nx monorepos.
  • Experience with TDD, testing frameworks, and auth integration (Auth0 or similar).
  • Ability to work autonomously in fast-paced environments.
  • Good communication skills and high level of English.
  • Comfortable working in AI-first environments, using tools like Copilot, Claude, or similar to accelerate delivery.


Nice to Have

  • Hands-on deployment of SPAs and APIs in AWS (S3, CloudFront, containerized services).
  • Familiarity with Angular SSR, Core Web Vitals, and front-end performance optimization.
  • Background in building and scaling production systems.
  • Exposure to accessibility standards (ADA/WCAG).
