ARIVE () is the industry's first integrated LOS, POS, and Pricing Engine with a connected Lender Marketplace, purpose-built for independent mortgage originators. We are a dynamic high‑growth company revolutionizing digital mortgage originations, and our platform seamlessly connects independent loan originators, top‑tier wholesale lenders, borrowers, referral partners, credit providers, and property and settlement service providers — creating a faster, more transparent, and more affordable path to home ownership.

We’re seeking a talented Senior Backend Engineer to design, support, and scale the services at the heart of the ARIVE platform — the engine powering loan originations for thousands of independent mortgage brokers nationwide. You’ll work hands‑on with Node.js, Type Script, PostgreSQL, MongoDB, AWS, and Docker, partnering closely with product, frontend, and Dev Ops teams to ship high‑quality, cloud‑native features at startup speed.

A key part of this role is production ownership — partnering with our support team to troubleshoot at‑scale production issues, driving root cause to resolution, and hardening the platform so problems stay fixed. You’ll also coordinate closely with our US architects and India‑based engineering team for new features. This is a high‑ownership role for an engineer who loves solving hard distributed‑systems and data problems in a domain where reliability, performance, and security truly matter.

You’ll take end‑to‑end ownership of major work streams alongside our most senior architects — freeing them to focus on next‑generation platform initiatives. Join us and make a meaningful, sustainable impact alongside some of the industry's brightest minds.
