The Applications Team defines and builds the software that data owners use to connect data scientists to their sensitive data. We are building a robust set of post-ETL tools that permit administrators to shape and refine their data before provisioning access to it. Our team owns permissions, user and data management, and the public GraphQL API that controls them. As a member of the Applications Team, you’ll be responsible for innovating ways to help data owners reason about the complex concepts underlying differential privacy, and providing an administrative API and UI for the entire system.
On the Applications Team, you’ll work across disciplines, technologies, and teams to solve problems. Modeling a database within a database, integrating with customer user management systems using standards like SAML, designing and documenting APIs for use with customer systems, and integrating monitoring and tracing, all while following the strictest standards for security in the industry.
Like all teams at LeapYear, we reason about our abstractions using strongly-typed, functional-forward languages like TypeScript and Haskell. We believe in tests and automated code quality tools. We also believe in an open, safe, inclusive, and collaborative environment where everyone is comfortable and supported to bring their whole selves.
– You enjoy building tools for technical users, but want to understand their needs first
– You are looking for a job where you can make the “jump” to a role with broader ownership – owning features, learning new technologies, interfacing with more stakeholders – and the support you need to get there
– You like being a polyglot and working on a diverse array of problems from day to day, instead of being highly specialized
– You like to ask questions and listen to people to help define and understand problems as much as you like writing the code to solve them
– You like to learn from and share your expertise with your teammates
– You’re comfortable pairing, working solo, or with teammates from other teams at LeapYear – Design, Product, Platform, Infrastructure, or Algorithms – as the problem requires
– You’re interested in building on-premises software for the enterprise where precision, correctness, and stability are more important than volume or scale
