As a Senior Fullstack Developer at ImprovMX, you’ll play a key role in shaping the architecture and direction of our core platform. You’ll work across the stack—contributing to frontend interfaces, backend api servers, and lower level cloud configuration—while collaborating closely with the founder and a small, nimble team.

Your work will directly impact tens of thousands of users who rely on ImprovMX for reliable and privacy-focused email forwarding. We’re looking for someone who thrives in a high-autonomy environment, is comfortable taking ownership from idea to deployment, and is excited to scale a bootstrapped, profitable SaaS product that values simplicity, performance, and developer happiness.

Here are some examples of what you'll be tackling:

• Build new features, from conception, design, implementation, iteration, and deployment
• Dive into server performance to optimize delivery, reduce costs, and improve reliability
• Handle on-call rotations to respond to production incidents
• Coordinate release and deployment of changes from multiple developers
• Read email protocol RFCs to improve our email deliverability and compliance
• Write algorithms to catch abusive users

• Strong proficiency with the latest AI tools (ChatGPT, Cursor, etc.)
• 5+ years of professional experience as a fullstack developer in a product-focused environment.
• Strong proficiency in modern JavaScript (Vue, React, etc.) and Python (Flask etc.).
• Solid understanding of database systems (SQL, MongoDB, redis, etc.)
