Senior Full Stack Developer - Remote

React | Node.js | TypeScript | Cloud | Full Stack Engineering

Position Type: Full-Time, Remote

Working Hours: U.S. Client Business Hours (with flexibility for sprint cycles, deployments, and production support)

About the Role

At Pavago, one of our clients is hiring a Senior Full Stack Developer to design, build, and scale modern web applications across both front-end and back-end systems.

This is a highly technical, hands-on engineering role where you’ll own features end-to-end-from user interfaces and APIs to databases, cloud infrastructure, and deployments.

You’ll work across:

• Front-end development
• Back-end services
• API development
• Databases
• Cloud infrastructure
• CI/CD
• Architecture
• Engineering mentorship

This is more than a coding role. You’ll help shape technical decisions, improve engineering standards, mentor developers, and contribute to building scalable, reliable products.

If you enjoy solving complex technical challenges while shipping production-ready features, this role is built for you.

What Happens After You Apply

Right after you apply, you’ll receive an email invitation from Spark Hire to record your Intro Video. This short, self-recorded video is the final step that completes your application and can be recorded whenever it’s convenient for you.

Instead of repeating yourself across multiple screening calls, you’ll introduce yourself once, and your video will be shared with the hiring team. This helps hiring managers evaluate your communication style early, making future interviews more meaningful and reducing unnecessary interview rounds.

Don’t overthink it-you can record your video as many times as you’d like before submitting it. Only your final submission will be reviewed.

Please keep an eye on both your inbox and spam folder for your Spark Hire invitation after submitting your application.
