Sr Software Engineer - Core Backend & Platform Engineering

WHO WE ARE  At Basis, we empower agencies and brands with cutting-edge software that automates digital media operations. Our all-in-one platform supports seamless planning, reporting, and financial reconciliation across direct, programmatic, search, and social media. We’re not just building advanced technology; we’re also building a culture where passionate, motivated individuals come together to drive meaningful change. Our commitment to inclusivity and growth ensures our employees thrive both professionally and personally. With our headquarters in Chicago, we offer flexible work options across the U.S. and Canada, including remote, hybrid, or on-site at headquarters. ABOUT THE TEAM  Technology is at the core of what we do. Basis is an industry-leading platform that automates and simplifies the entire digital ad campaign process. It processes over 300 billion events per day and uses AI and machine learning across the full campaign lifecycle.  The Core Backend team is the connective tissue that keeps Basis running and enables other engineering teams to move faster. We own the core backend, the foundational customer-facing features developed within it, and the systems and standards that feature teams build on top of.  We also define expectations for performance and reliability, observability foundations, and release tooling, along with the strategy for decomposing the system into well-defined microservices and evolving the application over time.  If you're energized by platform-level problems, by setting the standards other teams build on, and by work whose outcome is other teams shipping faster, this is the team for you.
