Principal Software Engineer - Full Stack

Job Description

We are hiring a Principal Software Engineer (Full Stack) to join our engineering team at Monto.

This is a hands-on, high-impact role for an experienced engineer who can take full ownership of complex systems from end to end. You will work across backend and frontend, designing and building production-grade systems that power our core product.

As a Principal IC, you are expected to operate independently, make architectural decisions, and drive execution — without relying on heavy product or management layers.

What You’ll Do:

• Design and build end-to-end systems across backend and frontend
• Own complex features from definition to production
• Improve system architecture, scalability, and performance
• Work closely with product, CS, and leadership on high-impact initiatives
• Make pragmatic technical decisions in a fast-moving environment
• Contribute to code quality, reliability, and engineering best practices

Requirements:

• 8+ years of software engineering experience
• Strong full-stack capabilities (backend + frontend)
• Strong backend development experience with Node.js and TypeScript
• Experience with modern frontend frameworks
• Proven experience building and scaling production systems
• Ability to work independently and take full ownership
• Strong problem-solving and execution skills

Nice‑to‑Have

• Experience with serverless architectures (e.g., AWS Lambda)
• Experience working with MongoDB or other document-based databases
• Experience in B2B SaaS environments
• Experience working in fast-paced startup environments
