We are currently looking for an experienced Full Stack Engineer (TypeScript, React, Node.js) to build and scale core product infrastructure for a fintech platform focused on revenue protection in the vacation rental industry. This role requires strong ownership across the stack, working with modern technologies like React, Node.js, and AWS serverless services. You will design and develop systems that handle complex workflows such as billing, claims, and integrations with external platforms. The ideal candidate is comfortable with ambiguity, fast iteration, and translating real-world business problems into reliable software. You will collaborate closely with product and operations teams to ensure accuracy and scalability. This position demands high attention to detail, as systems directly impact financial outcomes and customer trust. It’s an opportunity to shape both the product and engineering culture in a high-impact environment.

The platform includes several core systems:

PMS and marketplace data ingestion.
Reservation normalization.
Coverage and eligibility logic.
Dynamic pricing and premium calculation.
Invoice generation and reconciliation.
Claims automation and payment workflows.
Rebooking detection and claim offsets.
Customer-facing dashboards and reporting.
Internal admin tooling for operations, claims, and finance
Partner and insurer reporting infrastructure.

In this role you will:

Build and improve Roam’s core product systems across the stack.
Develop reliable integrations with PMS platforms, marketplaces, and third-party services.
Own business-critical workflows around reservations, coverage, invoices, and claims.
Work closely with product, operations, insurance, and customer teams to translate messy
real-world requirements into clean software.
Help design systems that are auditable, explainable, and financially accurate.
Improve internal tools that make Roam’s operations faster and more scalable.
Contribute to product strategy and technical architecture.
Help shape engineering culture as the team grows.
Balance fast iteration with pragmatic, durable technical decisions.
