About the Role

At Pavago, one of our clients is hiring a Senior Full Stack Software Engineer to build, scale, and maintain modern web applications and the infrastructure behind them.

This is a highly technical, hands-on engineering role where you’ll own features end-to-end — from front-end interfaces and APIs to deployments, scalability, and infrastructure reliability.

You’ll work across:

• Front-end development
• Back-end systems
• Cloud infrastructure
• CI/CD pipelines
• Performance optimization
• Technical architecture

If you enjoy shipping production-ready features, solving complex engineering problems, and building scalable systems, this role is built for you.
