Senior Full Stack Engineer

Why this is a massive opportunity

What you will do

• Within weeks:
• Ship features related to a key component of Sphere’s platform - e.g. filing infrastructure
• Own and manage this key component, driving measurable outcomes
• Work directly with customers like Eleven Labs, Replit and Windsurf to improve / optimize that key component of the platform (e.g. improve filing generation and submission speed [x]%)
• Within months:
• Develop expertise across other key components of Sphere’s platform - e.g. tax engine, new products - to manage and execute improvements in this area
• Lead / mentor additional engineers in component areas that you have worked in

Requirements

• Strong experience in Python . Our core application backend and data pipeline services are built with Python and Django
• While frontend / React may not be your primary focus, you’re not afraid to dive in when needed
• Very strong attention to detail. When you work with numbers this is a non-negotiable - it’s not enough to be 99% right.
• Nice to have:
• Experience working with large volumes of transaction data. You’ll be getting very familiar with it!
• Experience with Django or Python ORM
