We are seeking a highly skilled Full-Stack Engineer with at least 5 years of professional experience to join our growing team. The ideal candidate has a strong background in building modern web applications, is fluent in React/Next.js, experienced with backend development (Python preferred), and has hands-on exposure to infrastructure and DevOps practices.

You will play a key role in designing, developing, and maintaining high-quality, scalable, and secure systems across the stack — from frontend interfaces to backend APIs, databases, and deployment pipelines.

Key Responsibilities

  • Design, develop, and maintain frontend applications using React and Next.js.

  • Build, test, and deploy backend services and APIs (Python/Django/FastAPI preferred, but other languages/frameworks welcome).

  • Collaborate with founders, growth team, designers, and other engineers to deliver high-impact features.

  • Ensure scalability, performance, and security across the stack.

  • Implement CI/CD pipelines, automated testing, and monitoring solutions.

  • Contribute to infrastructure planning, deployment, and optimization in cloud environments (AWS, GCP, or Azure).

  • Mentor junior developers and promote engineering best practices.

Required Qualifications

  • 5+ years of professional software engineering experience.

  • Proven experience with React and Next.js in production environments.

  • Strong backend development skills (Python preferred)

  • Solid understanding of relational and/or NoSQL databases.

  • Experience with Git and collaborative development workflows.

  • Knowledge of cloud infrastructure, containerization (Docker, Kubernetes), and CI/CD pipelines.

  • Strong problem-solving skills and a passion for building great products.

  • Experience implementing background workers and task queues (Celery, RQ, etc.).

  • Proficiency with Redis for caching, pub/sub, or job queues.

What We Offer:

  • You will be reporting directly to the founders, who have two successful venture-backed exits under their belt.

  • Competitive salary + equity

  • Supportive and innovative work environment.

  • Opportunity to help shape and build a generational company

What you can expect:

  • It won't be easy; in fact, it will be very hard.

  • BUT, it will be a lot of fun.

  • You need to be comfortable with being uncomfortable; timelines will change, priorities will most likely shift.

To conclude, we're building a team of like-minded, incredibly smart, tenacious individuals with relentless work ethic and focus, all driving towards our very clear revolutionary mission. If you match this description, buy into that mission and you're at a career stage where you're ready to make your defining statement to the world, please apply.
