Our teams tackle challenges ranging from enabling real-time user collaboration on detailed maps to building high-scale backend architecture for ingesting billions of data points. You'll collaborate directly with deployment teams and users to iterate and solve their problems, delivering value that aids emergency responders and addresses complex organizational challenges. Our tech stack includes a backend foundation of Python, Django, Celery, Airflow, and Kafka; a frontend built in React, Redux, and Mapbox; data stores including PostgreSQL and Elasticsearch; machine learning models hosted in Bedrock and Sagemaker; and AWS, Pulumi, Terraform, and Kubernetes as underlying infrastructure. Required qualifications: 8+ years of experience working with cross-functional software development teams; degree in Computer Science or related field (or equivalent); proven track record shipping and iterating on production-grade software components; ability to write robust, well-tested, well-designed code deployed to users; solid understanding of architecting and scaling distributed software systems; strong best practices in modern software development and comfort navigating large codebases; located in San Francisco, CA and open to working in office.
