Senior Software Engineer - Backend

Responsibilities

• Architect, develop, and maintain scalable RESTful APIs and backend services using Node.js and TypeScript, powering mission-critical loan origination workflows.
• Design efficient database schemas and optimize queries and migrations across PostgreSQL and MongoDB; implement caching strategies (e.g., Redis) for high-throughput workloads.
• Build, test, and deploy containerized applications with Docker; deploy and operate services on AWS (EC2, Lambda, RDS, S3, SQS).
• Partner with DevOps to strengthen CI/CD pipelines, infrastructure-as-code, and observability (logging, metrics, tracing, alerting).
• 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.
• 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.
• 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.
• Lead technical design sessions and code reviews, mentor mid‑level engineers, and contribute to product planning and architectural roadmaps.

Requirements

• 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.
