Who you are

• 6+ years of professional backend engineering experience, with significant time spent in Python and Django
• Expert-level knowledge of Django Core and Django REST Framework, including a deep understanding of the request/response lifecycle—and the judgment to know when to use (and remove) tools like signals
• Deep experience with relational databases at scale (PostgreSQL and/or MySQL), including indexing strategies, locking behavior, and transactional integrity in distributed systems
• Strong comfort operating in AWS, including practical experience with services like RDS, SQS (visibility timeouts), S3 lifecycle policies, and debugging IAM/VPC networking issues
• Experience working in large, existing codebases, not just greenfield development
• A proven track record of delivering well-designed, well-tested, performant systems in an agile, remote-first environment
• Exceptional written and verbal communication skills, with the ability to clearly explain technical decisions to both technical and non-technical stakeholders
• Strong fundamentals in algorithms and data structures, and how they behave at scale in real systems
• The expectations above are meant to represent the ideal candidate, but if you don’t meet all of them and think you’d be a great fit for this role, please apply. This position is open to candidates who are authorized to work in the posted location. Immigration sponsorship is not available at this time
