Backend Engineer • Senior

Who you are

You have 5+ years of backend engineering experience building production systems at scale — you've owned services from design through deployment and have a deep understanding of performance and reliability in high-scale environments. Your expertise in Java and Python allows you to develop robust backend solutions that meet the needs of internal and external customers alike. You are comfortable working in a collaborative environment, partnering with product, data science, and customer success teams to turn real-world signals into impactful product improvements.

You thrive in a culture that values correctness and design — you understand the importance of shipping small, reversible changes with strong safeguards. Your experience with multi-tenant services means you know how to balance the needs of various stakeholders while maintaining a high bar for ownership and impact. You are detail-oriented and have a strong focus on developer experience, ensuring that the systems you build are not only functional but also user-friendly for your fellow engineers.

Desirable

Experience with experimentation platforms or A/B testing frameworks would be a plus, as would familiarity with cloud services like AWS or GCP. You are open to learning new technologies and methodologies that can enhance your team's performance and the quality of the products you deliver.
