Take ownership of smaller modules and grow into larger responsibilities over time.

Debug, test, and optimize systems to ensure reliability and speed.

What We’re Looking For :

2–3 years of hands-on full-stack development experience.

Proficient in JavaScript / TypeScript, React, Next.js, Node.js.

Solid understanding of databases (PostgreSQL or MySQL) and RESTful APIs.

Strong problem-solving mindset with attention to detail.

Curiosity about payments, fintech, or SaaS products.

Eager to learn, move fast, and take ownership beyond your experience level.

Bonus Points :

Exposure to payment gateways, fintech APIs, or data-heavy systems.

Experience with Python, ClickHouse, or cloud deployments (AWS, GCP).

Interest in data pipelines, analytics, or event-driven architecture.

What Success Looks Like

Within 30 days : You’ve shipped features and understand how our stack fits together.

Within 90 days : You’re owning a module or service end-to-end.

Within 6 months : You’re solving complex product challenges with autonomy and precision.
