Troubleshoot integration challenges, improve performance, and support production rollouts
Stay hands-on with the full development lifecycle, from planning to release

Backend Developer - Data Requirements

Experience with backend data integration, ETL workflows, or PIM systems
Proficiency in Python and JavaScript (Next.js experience a plus)
Working knowledge of Kafka and PostgreSQL
Experience with Informatica P360 and its API integrations (strongly preferred)
Solid understanding of API development and system integration
Strong problem-solving skills and ability to work across business and technical teams
Comfortable interfacing with senior leadership and cross-functional collaborators
