About The Position

We’re looking for a top-tier Senior Full Stack Developer who’s passionate about building world-class user experiences and loves working at the intersection of beautiful frontends and powerful backends. If you're a React expert who enjoys diving into backend challenges (especially in Python), and you thrive in a fast-paced, high-impact environment - this role is for you.

At Second Nature AI, we're building a cutting-edge, AI-powered conversation platform that lives in the browser - real-time audio, WebSockets, and all. You'll play a key role in bringing that vision to life, collaborating with talented product and design teams to deliver intuitive, high-performance features that feel like magic to our users.

Key Responsibilities

  • Architect, develop, and maintain sophisticated web applications using React with performance, responsiveness, and UX excellence in mind
  • Own and contribute to backend services, APIs, and infrastructure — Python and Django are a strong bonus
  • Solve tricky bugs, tackle performance bottlenecks, and drive continuous improvements across the stack
  • Work closely with product managers and designers to turn complex ideas into elegant, user-friendly solutions
  • Ensure top-notch speed, scalability, and accessibility across the app
  • Participate in code reviews, design discussions, and mentor team members with your experience and insight

Qualifications

  • Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field
  • 8+ years of hands-on development experience, with deep expertise in React and modern frontend architecture
  • Solid backend development background — Python experience required; Django a plus
  • Comfortable with testing frameworks, CI/CD practices, and code quality tools
  • Strong product and UX intuition, with a passion for crafting smooth, delightful interfaces
  • Clear communicator who thrives in collaborative, cross-functional teams

Bonus Points

  • Experience with additional frontend frameworks or advanced patterns
  • Exposure to cloud platforms (AWS/GCP), Docker, or Kubernetes
  • Passion for mentoring and helping others grow
