Software engineer (Python / JavaScript) — AI-first (Vibe coding)

About Us

We're a fast-growing Series A startup backed by $34M in funding and driven by a team that moves fast, stays curious, and cares about high-quality execution.

We’re looking for a Developer with 2–3 years of experience who is ready to work in an AI-assisted format: using AI tools to speed up development while maintaining quality through architecture, tests, code reviews, and proper validation. We’re in the middle of an engineering transformation—adopting modern practices, improving our delivery process, and scaling AI-assisted development in a responsible way. We have a strong base of real-world experience and proven approaches, and we’re building the next iteration of our engineering playbook. You’ll have room to learn, experiment, and help shape how we work—while staying grounded in quality, reliability, and maintainability.
