Senior Fullstack Engineer

Position : Senior Fullstack Engineer (with Data Engineering Experience)

Location : Remote (collaboration across time zones), India or LATAM preferred

Engagement Type : Contract (12+ months)

Language : Proficient English communication

Experience : 5+ years in Full-Stack Engineering / Backend Engineering, with meaningful exposure to data systems and applications

About the role

We’re looking for a hands-on Senior Fullstack Engineer who can own features end-to-end : backend services, frontend experiences, and the data flows that power them. Your primary strength is building web applications and APIs, and you have some experience working with databases or analytics, plus a clear interest in doing more with data integration and pipelines. You’ll design and build APIs, UIs, and supporting infrastructure, and you’ll also build and maintain frontend SDKs (Next.Js / React) that other teams can use to integrate with the platform.

You should be comfortable moving between frontend (React / Next.Js + TypeScript), backend (e.G., Node.Js or Python), and cloud infrastructure (strong Azure or AWS preferred). You’re curious about how data moves through the system and want more hands-on opportunities at those integration points. You communicate clearly (async chat and live sessions), learn fast, and use AI coding tools (e.G., Claude Code) effectively - without relying on them as a crutch.

We are looking for candidates who can join in December 2025, even if part time for the first few weeks.
