## About the Role

* 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.
 * Previous startup experience or working in an environment where engineers need breadth, sound judgment, and strong problem-solving skills.
 * Demonstrated experience turning ambiguous product needs into sound technical architecture and production-ready solutions.
 * The ability to navigate complex datasets and interconnected tables to investigate issues, trace dependencies, and identify the right path forward in ambiguous technical situations.
 * Working frontend experience with technologies such as React and TypeScript; deep frontend specialization is not required.
 * Strong coding fundamentals and the ability to solve technical problems independently, with AI used as an accelerator rather than a substitute for core capabilities.
 * A generalist mindset and willingness to work across backend, frontend, pipelines, and infrastructure when the product requires it.

You may be a strong fit if

 * Most of your experience is in data-intensive backend engineering, but you have also shipped frontend work.

## Description

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.
