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.

• Design & Build: Architect, develop, and maintain scalable RESTful APIs and backend services using Node.js and Type Script, powering mission-critical loan origination workflows.
• Data Engineering: Design efficient database schemas and optimize queries and migrations across PostgreSQL and MongoDB; implement caching strategies (e.g., Redis) for high-throughput workloads.
• Cloud & Containers: Build, test, and deploy containerized applications with Docker; deploy and operate services on AWS (EC2, Lambda, RDS, S3, SQS).

• Production Ownership: Partner with our Support team as an engineering point of contact for escalated production issues at scale — triage, root-cause, and resolve end-to-end, then land the permanent fix, alerting, and runbooks so issues don’t recur. Drive performance optimization across the backend and data layers.

  Collaboration:
  
  Coordinate daily with our India-based engineering team — handoffs, code reviews, and design alignment — keeping core hours of 7:00 AM – 4:00 PM PT to maximize morning overlap.
