• Investigate production issues, design clear interfaces, and deliver maintainable solutions.

WHAT WE'RE LOOKING FOR

• At least 3 years of backend engineering experience building and maintaining production services.
• Practical experience with Python and/or TypeScript/Node.js, and willingness to work across both.
• Experience with PostgreSQL or another relational database, including data modeling and transactions.
• Experience with background jobs, queues, or event-driven processing, including failure handling and data consistency.
