About the Role

We’re looking for a senior-level software engineer who leans backend and can take product problems from first principles through implementation. You’ll spend roughly 70% of your time on backend and distributed systems work and 20–30% on frontend work, giving you the ability to own features across the stack when needed.

You’ll help take new products and capabilities from early traction to meaningful scale — designing reliable backend systems while contributing the frontend components required to deliver complete product experiences. This work could include helping expand our new incrementality offering into a scalable experimentation platform, building near real-time data infrastructure or building AI into our marketing user's workflows. You'll have an opportunity to collaborate with a cross-functional team of data scientists, product managers, and designers along the way.

Your Impact

- Scale our new incrementality product into a reliable, repeatable experimentation platform.

- Develop near-real-time ingestion and processing capabilities to move beyond batch workflows.

- Build new AI-powered workflows that help marketers evaluate performance and act on insights.

- Improve connection-state systems and help extend the partner ecosystem across data ingestion and exports.

- Work on other product areas such as role-based access control (RBAC).

- Contribute to frontend work when needed to deliver complete experiences.

What You Bring

- 5+ years of experience designing and building distributed backend systems, microservices, APIs and/or data processing systems written in Python.

- Multiple years of professional experience building system architecture.

- Experience working closely with product managers, designers, and data scientists while independently driving implementation and delivery.
