Senior Software Engineer (Backend)

ARIVE builds a digital mortgage origination platform for independent mortgage originators. The Senior Backend Software Engineer designs, scales, and supports backend services, owns production issue resolution, and collaborates with product, frontend, DevOps, and engineering teams to deliver reliable platform features.

Responsibilities:

• Design & Build: Architect, develop, and maintain scalable RESTful APIs and backend services using Node.js and TypeScript, 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)
• DevOps Collaboration: Partner with DevOps to strengthen CI/CD pipelines, infrastructure-as-code, and observability (logging, metrics, tracing, alerting)
• Reliability & Security: Champion system reliability, performance, and secure coding best practices — our platform handles sensitive borrower data, and we operate in a SOC 2 Type II environment where security is a first-class engineering concern
• 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
• Global 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
• Technical Leadership: Lead technical design sessions and code reviews, mentor mid-level engineers, and contribute to product planning and architectural roadmaps

Requirements:

• Candidates must be authorized to work in the United States on a full-time basis. Visa sponsorship is not available for this position
• 5+ years of hands-on backend engineering experience with most, if not all, of the following: Node.js, TypeScript, PostgreSQL, MongoDB, AWS, and Docker
• Strong command of RESTful API design, microservices and event-driven architectures, and message queues (e.g., SQS, Kafka, RabbitMQ)
• Deep experience with both relational and NoSQL data modeling, query optimization, indexing strategies, and zero-downtime migrations
• Solid habits around automated testing (unit, integration, E2E), code review, and CI/CD; you ship fast without breaking things
• Working knowledge of secure SDLC practices — authN/authZ patterns (OAuth 2.0, JWT), OWASP Top 10, and handling sensitive data in a regulated environment
• Experience with monitoring and APM tooling (e.g., Datadog, CloudWatch, New Relic) and a bias toward measuring before optimizing
• You've served as an engineering point of contact for support escalations and stay calm and methodical when debugging live production systems under pressure
• You leverage AI coding tools to maximize your speed and output — and are excited to help build AI-powered capabilities into the platform
• Proactive, self-directed, and comfortable with ambiguity; you thrive in a fast-paced, high-ownership environment and communicate clearly across teams
• FinTech, mortgage, or other regulated-industry experience; familiarity with LOS/POS platforms or the loan origination lifecycle is a strong plus
