What you’ll do:
- Work with product and engineering to understand the business problems related to place metadata, including how it’s processed and stored, and define the requirements for machine learning models and algorithms to solve them.
- Automate ETL pipelines to process large databases of POIs from different sources efficiently and reliably.
- Prototype, deploy, and maintain new models and algorithms for POI matching/conflation, source evaluation, identifying closed businesses, scraping metadata, extracting attributes from UGC, and flagging inaccurate data
- Communicate progress, experimental findings, and insights clearly and concisely to both technical and business stakeholders
What we are looking for:
- A master’s degree or PhD in computer science, data science, engineering, statistics, or a related field.
- 2+ years of experience in developing and deploying end-to-end machine learning models and algorithms at scale.
- Proficiency in Python, R or a similar numerical/statistical programming language
- Ability to interpret and write complex SQL queries
- Experience with handling data heterogeneity, incompleteness, duplication, and uncertainty issues in large datasets
- Preferred: Experience working with large POI databases and/or geospatial data

We are looking for passionate engineers with experience in Python, Java, Ansible, PostgreSQL, CentOS, and Alma Linux, to help us optimize and automate our infrastructure and deployment processes. We are currently involved in several types of systems migrations, within both the scope of on-prem to aws/cloud-native migrations, as well as on-prem data center to alternate on-prem data center migrations. As a SiteOps Engineer you will be involved in designing and implementing how we perform those migrations, testing those migrations, and then performing them with a “no surprises in production” mindset.
Responsibilities:
- Infrastructure Automation: Design, implement, and maintain automated infrastructure provisioning and configuration management using tools like Ansible to ensure consistency and scalability.
- Monitoring and Alerting: Set up monitoring and logging systems to proactively detect and address potential issues, ensuring optimal performance and reliability, in environments like on-prem Prometheus/Thanos, as well as Grafana Cloud and Grafana Cloud Loki.
- Database Management: Manage hundreds of on-prem PostgreSQL databases, including performance tuning, backups, and disaster recovery strategies.
- Collaboration: Work closely with cross-functional teams, including developers and system administrators, to improve the overall development and deployment processes.
- Troubleshooting and Incident Management: Assist in identifying and resolving operational issues and participate in on-call rotations.
Requirements:
- At least 3-4 years in the same or similar position.
