A day in the life
You might start your morning reviewing a technical design document, providing feedback that helps a teammate refine their approach. By mid-morning, you're deep in code - prototyping a critical interface or refactoring a component to improve reliability. After lunch, you join a cross-team architecture discussion where you advocate for a pragmatic path forward. Later, you pair with a junior engineer on a tricky problem, helping them break it down into manageable pieces. Throughout the day, you move fluidly between hands-on coding, technical leadership, and collaboration.

About the team
Our team is developing a fine-tuned LLM trained on proprietary ads data to power the next generation of advertiser experiences. The work is highly ambiguous and everyone on the team has the opportunity to lead complex efforts where there are no existing solutions or playbooks to start from.
