Machine Learning Software Engineer, Notion

• Team player: For you, work isn't a solo endeavor. You have worked cross-functionally to establish the right overarching data architecture for a company's needs, to build data ingestion (real-time & batch), and to provide guidance on best data practices for the business
• Data expertise: You have built and managed highly scalable data processing solutions (e.g. Spark, Flink), data lakes or warehouses (e.g. Snowflake, Hive), authored queries (SQL), used workflow management (e.g. Airflow, Luigi), and have experience maintaining the infra that supports these
• Thoughtful problem-solving: For you, problem-solving starts with a clear and accurate understanding of the context. You can decompose tricky problems and work towards a clean solution, by yourself or with teammates. You're comfortable asking for help when you get stuck
• Pragmatic and business-oriented: You care about business impact and prioritize projects accordingly. You're not just going after cool stuff—you understand the balance between craft, speed, and the bottom line
• Put users first: You think critically about the implications of what you're building, and how it shapes real people's lives. You understand that reach comes with responsibility for our impact—good and bad
• Not ideological about technology: To you, technologies and programming languages are about tradeoffs. You may be opinionated, but you're not ideological and can learn new technologies as you go
• Empathetic communication: You communicate nuanced ideas clearly, whether you are explaining technical decisions in writing or brainstorming in real time. In disagreements, you engage thoughtfully with other perspectives and compromise when needed
