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.

Key Responsibilities

• Product features end-to-end : Design, build, and ship user-facing features across backend and frontend; own requirements from spec to production rollout.
• APIs & backend services : Implement and maintain RESTful (and occasionally event-driven) services; design clean request / response contracts; handle auth (OAuth2 / OIDC / JWT), rate limiting, idempotency, validation, and auditing.
• Frontend development & SDKs : Build responsive, accessible UIs using React / Next.js + TypeScript (dashboards, admin / ops views, analytics-flavored screens). Design and maintain a frontend SDK (hooks, components, and utilities) that product teams can use to integrate with backend APIs and data services. Provide example Next.js integration patterns and reference implementations.
• Data-aware design : Work with product and data teams to design schemas and models that support both product workflows and analytics; understand how data will be queried and reported on.
• Integration with data pipelines : Collaborate with data engineers to consume and expose curated datasets; design APIs and services that sit on top of warehouses / lakes and operational databases.
• Infrastructure & DevOps : Use Terraform or similar IaC to provision and manage app infrastructure; automate build / test / deploy with CI / CD; write solid shell scripts for glue / ops tasks.
• Observability & reliability : Instrument structured logs, metrics, and traces across services and UIs; define alert policies and on-call runbooks; help track SLOs and drive root-cause prevention.
• Security basics : Apply least-privilege access, secrets management, and encryption in transit / at rest; support secure-by-default patterns in API, SDK, and UI design.
• Quality & tests : Write unit, integration, and end-to-end tests (for both backend and frontend); contribute to contract tests and data-quality checks where the app touches data pipelines.
• Collaboration & docs : Communicate clearly in writing and in person; produce concise docs (API specs, SDK docs, data contracts, feature runbooks, UI flows); work closely with product / engineering / analytics.
