Build high-performance analytics software used by leading eCommerce brands to make real revenue decisions.

Our Client is scaling one of the most advanced marketing intelligence platforms in the market. Their product gives brands a unified, reliable view of ad spend, attribution, and the full customer journey through powerful dashboards and analytics infrastructure. They have strong product-market fit, rapid growth, and are expanding their engineering team.

They are hiring a Senior Fullstack Engineer (TypeScript) to own major product features across the stack and help shape the technical direction of the platform.

The Role

This is a true product engineering role. You will design, build, and ship end-to-end features that power a sophisticated analytics dashboard used daily by enterprise customers.

You will work closely with product managers, customer success, and users to translate real-world needs into scalable technical solutions.

The role combines frontend performance, backend services, and data-heavy systems. You will operate with high autonomy and significant ownership.

What You’ll Do

- Own features end-to-end, from design through production deployment

- Build and scale complex dashboard experiences using React and TypeScript

- Develop and maintain backend services using REST and GraphQL APIs

- Write and optimize SQL queries across large datasets

- Improve performance, rendering speed, and developer ergonomics

- Help define technical direction and engineering best practices

- Mentor engineers and contribute to internal technical documentation

- Balance rapid iteration with long-term maintainability

What They’re Looking For

- 5+ years building frontend and backend systems using TypeScript

- 3+ years working with React or modern component-based frameworks

- Experience building API services (REST and/or GraphQL)

- Strong SQL skills, ideally with BigQuery experience

- Ability to independently ship production-ready code

- Strong systems thinking and ability to balance speed with architecture

- Experience collaborating cross-functionally in product-driven teams

Nice to have:

- Python experience

- Experience building design systems

- Experience optimizing data-heavy frontends

- Data visualization experience

- Background in marketing, eCommerce, or ad-tech

Why This Role Stands Out

- High ownership product role, not a narrow feature contributor

- Work on data-intensive dashboards used for real revenue decisions

- Direct collaboration with users and customer-facing teams

- Strong product-market fit and rapid growth

- Opportunity to influence technical direction in a scaling company

If you enjoy building performant, data-heavy web applications and want real ownership in a fast-moving product team, this is a strong opportunity.
