Lead Backend Engineer (AWS + TypeScript)

We’re Blazity - a team of React.js and Next.js experts creating powerful web experiences. We have years-long relationships with many of our clients. As trusted development partners, we take full ownership of the projects and continuously optimize apps, stores, websites, and implement new features, or automate workflows.

We’re looking for a highly experienced Lead Backend Engineer with a strong grasp of AWS and TypeScript to join a project for a configurator for RCS messages, built as a modern alternative to SMS and WhatsApp for marketing communication, designed for technical users like admins who build message templates and integrate directly with APIs.

The application is built and live. Your main focus will be on backend development and API work, with a touch of architecture and DevOps responsibilities. You'll take over key responsibilities and work closely with team on scaling and optimizing the platform.

This is a hands-on coding role for someone with deep AWS knowledge and production-level experience writing backend systems in TypeScript. We’re looking for someone who enjoys solving technical challenges, improving architecture, and scaling systems that are already in production.
