About ARIVE ARIVE (arive.com) 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 homeownership. Position Overview 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, TypeScript, PostgreSQL, MongoDB, AWS, and Docker, partnering closely with product, frontend, and DevOps 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 workstreams 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. Key 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. Things We Look For - Experience: 5+ years of hands-on backend engineering experience with most, if not all, of the following: Node.js, TypeScript, PostgreSQL, MongoDB, AWS, and Docker. - API & Systems Design: Strong command of RESTful API design, microservices and event-driven architectures, and message queues (e.g., SQS, Kafka, RabbitMQ). - Data Fluency: Deep experience with both relational and NoSQL data modeling, query optimization, indexing strategies, and zero-downtime migrations. - Quality Mindset: Solid habits around automated testing (unit, integration, E2E), code review, and CI/CD; you ship fast without breaking things. - Security Awareness: Working knowledge of secure SDLC practices — authN/authZ patterns (OAuth 2.0, JWT), OWASP Top 10, and handling sensitive data in a regulated environment. - Observability: Experience with monitoring and APM tooling (e.g., Datadog, CloudWatch, New Relic) and a bias toward measuring before optimizing. - Escalation Experience: You’ve served as an engineering point of contact for support escalations and stay calm and methodical when debugging live production systems under pressure. - AI-Forward: You leverage AI coding tools to maximize your speed and output — and are excited to help build AI-powered capabilities into the platform. - Startup DNA: Proactive, self-directed, and comfortable with ambiguity; you thrive in a fast-paced, high-ownership environment and communicate clearly across teams. - Bonus Points: FinTech, mortgage, or other regulated-industry experience; familiarity with LOS/POS platforms or the loan origination lifecycle is a strong plus. What We Offer - Compensation: The US base salary range for this full-time position is $120,000 – $180,000 + up to 15% performance-based bonus. The position is eligible for performance-based equity compensation. Our salary ranges are determined by location, level, and role; individual compensation will be determined by experience, skills, and job-related knowledge. - Comprehensive medical, dental, and vision insurance. - 401(k) plan with employer match. - Generous PTO policy. - Endless learning and growth opportunities in a fast-paced, growth-mode startup environment. - A supportive, inclusive, and high-performance company culture.
