The Applied Machine Learning group at Redfin works towards redefining real estate in the customer’s favor using machine learning. We work on foundational problems in the real estate space including recommendations (“Where should I live?”) and price estimation (“How much is a home worth?”). The Brokerage Recommendations product alone, which we power drives 27% of all traffic to Redfin platforms. We have real estate data at a national level and work across various domains in machine learning using large-scale multi-modal property data (documents, images, text, video, 3D scans etc.). Our team also owns and maintains end-to-end production-grade large-scale machine learning infrastructure and systems serving hundreds of millions of consumers.

As a Senior Software Engineer embedded on the Applied Machine Learning Team, you’ll architect the heavy-duty infrastructure that powers our entire ML ecosystem, using Kubernetes and Terraform to build a foundation capable of processing millions of records every minute. By engineering high-reliability data pipelines and Tier 1 APIs, you’ll provide the rock-solid platform our team needs to deploy and scale world-class models with absolute confidence.

The Role:

• Architect High-Scale ML Infrastructure: Engineer the machine learning backend and data pipelines that power a brokerage platform with 7x the traffic of our closest competitor, directly scaling solutions for millions of users.

• Drive Revenue-Critical Innovation: Design and deploy high-impact data products and analytical tools that move the needle on Redfin’s most vital business metrics and top-line revenue growth.

• Revolutionize the Home-Buying Experience: Build the features that redefine how people buy and sell homes, translating complex data into seamless, life-changing user experiences.

• Champion System Resilience: Act as a critical line of defense by spearheading debugging and incident recovery efforts, ensuring the 24/7 reliability of our mission-critical services.

• Level-Up Engineering Excellence: Act as a force multiplier for the team by identifying efficiency bottlenecks and evangelizing technical learnings across the broader Redfin engineering organization.

• Lead Modernization & Best Practices: Maintain a cutting-edge tech stack by integrating industry-leading tooling for observability, logging, and automated deployment.

• Own the Full Data Product Lifecycle: From inception to production, you’ll build the analytical engines that empower data-driven decision-making at every level of the company.

Who You Are:

• You have 5+ years of software engineering experience, with a primary focus on distributed systems and data platform architecture.

• You possess deep expertise in AWS (S3, Kinesis, DynamoDB, SageMaker), data engineering (database, pipelines, ETL, and large-scale data processing), and have professional experience with Infrastructure as Code (Terraform or CloudFormation) and Kubernetes.

• You have a proven track record of building "Tier 1" data pipelines using Kafka, Airflow, and Spark that are capable of processing millions of records per minute with high reliability.

• You are highly proficient in Python and familiar with SQL. While you are not responsible for building models, you understand the data requirements for libraries like NumPy and Pandas to ensure the platform effectively supports ML workloads.

• You have experience implementing monitoring and observability for complex systems (e.g., CloudWatch, Grafana, Datadog) and are comfortable participating in an on-call rotation for mission-critical services.

• You act as a technical leader who can design system architectures from scratch and mentor the team on engineering best practices, including CI/CD, testing, and documentation.
