Overview

We're hiring a Senior Software Engineer to join a fast-paced, high-urgency project developing a confidential, closed-source application. This fully remote role calls for an experienced full-stack developer who can work independently, design scalable systems, and contribute across both backend and frontend disciplines.

What You'll Do6

  • 1Design, build, and maintain full-stack applications from end to end.
  • 2Develop and integrate APIs and MCP-based systems to connect services.
  • 3Partner closely with engineering and product teams to align technical solutions with business goals.
  • 4Write clean, production-ready code that is easy to maintain and scale.
  • 5Identify bottlenecks, troubleshoot issues, and continuously improve application performance.
  • 6Contribute to architectural decisions and technical design discussions.

Requirements6

  • 1Several years of professional experience as a Full-Stack Developer building complex web applications.
  • 2Strong proficiency in Python, with hands-on experience writing robust backend services.
  • 3Proven experience with MCP (Model Context Protocol) and API development.
  • 4Ability to commit to at least 8 hours per day in a remote, self-directed work environment.
  • 5Track record of shipping and maintaining production-grade applications.
  • 6Excellent problem-solving skills and clear communication abilities.

Who Should Apply

This role is ideal for an independent, seasoned full-stack developer who thrives on owning the full lifecycle of features—from whiteboarding to deployment. You should be equally comfortable deep-diving into Python backend logic, wiring up APIs and MCP integrations, and crafting frontend experiences. If you enjoy working autonomously on high-impact, closed-source projects and have a knack for delivering scalable, production-ready solutions, we want to hear from you.

Salary Insight

Hourly rate ranging from $80.00 to $130.00, based on experience and expertise. This is a full-time engagement with full remote flexibility.

Application Tip

In your application, highlight a specific project where you built and integrated MCP-based systems or similar custom API layers. Walk through how you designed for scalability and what production challenges you overcame—it will set you apart.
