Backend-Focused Full-Stack TypeScript Developer (AI / SaaS)

Seeking a developer with strong backend TypeScript skills who can also handle or learn Next.js.

We combine cutting-edge LLM technology with real-world SMB know-how to create a virtual answering solution that takes care of everything—from booking appointments and taking messages to fielding routine questions—so teams can focus on what they do best. Founded by seasoned entrepreneurs with deep SMB experience, we're a tight-knit, fully distributed crew who believes the future of work should be smarter, more efficient, and more fulfilling.

If you're excited about shaping the next wave of AI innovation, you'll feel right at home at Upfirst.

What You'll Do

You'll use the technologies and tools below to help us build and extend the Upfirst platform.

• Backend: Build and maintain TypeScript microservices (server-side focus).
• Event-Driven: Use Google Pub/Sub or similar.
• Database: Working with MongoDB.
• Frontend (as needed): Work with or learn Next.js.
• Cloud Deployment: Leverage Docker on GCP (Cloud Run, Load Balancing).
• Infrastructure & CI/CD: Automate with Terraform (CDK preferred) and GitHub Actions.
• AI & Telecom: Integrate text-to-speech, speech-to-text, OpenAI APIs, and phone/SMS services (eg, Twilio). Willingness to learn is required.

What are we looking for?

Nice-to-Haves (Learn on the Job)
