About The Position

Realtor.com® is seeking a Senior Full-Stack Software Engineer to join their high-performance engineering organization as a full-time, hands-on individual contributor. The engineer will be embedded within a cross-functional team owning critical segments of the consumer ecosystem. The engineering organization is structured so that each domain team owns its vertical stack end-to-end—from backend microservices and APIs through frontend and DevOps. The ideal candidate is innovative, proactive, and self-driven, actively seeking out better tools, raising quality standards, and delivering without waiting for direction. The company values self-learners who challenge the status quo, take pride in the reliability of their work, and comfortably navigate ambiguity in a fast-paced environment. Potential teams include New Constructions, Mortgage & Financial Services, and Rentals Post-Lead & B2B Partnerships.

Requirements

5+ years of professional software engineering experience building and scaling distributed systems and high-traffic, consumer-facing products.
Proven depth across backend services, RESTful/GraphQL APIs, modern frontend frameworks (React or equivalent), and cloud/DevOps.
Strong experience with Node.js and microservice architectures.
Experience building search, marketplace, listing-based, or financial services products (e.g., loan application flows, rate calculators, lender/partner API integrations).
Direct ownership of production infrastructure, including observability, SLOs, and incident management.
Strong project management skills to independently drive features from scoping through delivery in an agile, matrixed environment.
Bachelor’s degree in Computer Science or equivalent practical experience.
Hands-on experience integrating AI-assisted development tools into your daily workflow.
Familiarity with event-driven architectures (e.g., Kafka, RabbitMQ, SQS/SNS) and data pipelines (e.g., Snowflake, S3, Aurora, reverse ETL).
Experience deploying and operating services on AWS using Kubernetes and containerization.
Familiarity with federated GraphQL architecture.
Understanding of financial data sensitivity and compliance considerations relevant to consumer financial products (e.g., RESPA, TILA awareness).
Comfort working in a data- and metrics-driven engineering culture aligned with performance KPIs.

Responsibilities

Design, build, and maintain high-traffic features and partner integrations across the full vertical stack (backend, APIs, frontend, infrastructure, databases).
Write well-tested, production-ready code.
Own and enforce test automation standards (unit, integration, E2E) in line with an engineering-owned quality model.
Take full accountability for the operational quality, observability, and reliability of your services—including setting SLOs, monitoring, alerting, and incident response readiness.
Ensure data integrity, secure engineering practices, and compliance-aware design when handling sensitive consumer, financial, and high-volume marketplace data.
Leverage and champion the adoption of AI-assisted development tools (e.g., Claude Code, Windsurf, Portkey, Gemini) to optimize development workflows.
Drive project delivery with strong personal ownership—managing scope, timelines, and cross-functional dependencies.
Communicate technical concepts clearly to non-technical stakeholders to build trust quickly.
