About Moon

An ambitious and independent stealth SaaS company incubated by Home Organizers, a market leader with decades of proven success in designing and delivering exceptional, innovative home organization solutions through its subsidiaries Closet World, Closets by Design, Brio Water Technology, and others. Backed by their deep industry experience and a commitment to be Home Organizer’s critical SaaS provider for its 6000+ employees, our team is building innovative solutions to solve universal problems that most businesses face — yet are not addressed by a single, unified tool. 

Our mission is to transform the entrepreneurial experience and deliver operational excellence for businesses across the world through a unified platform supercharged with proprietary AI agents. We want to unleash the creativity of billions and inspire the world to dream big and build fast. We’re a rapidly growing team of forward-thinking and, most importantly, committed builders. We are driven by the opportunity to push boundaries, reimagine the foundations of human work, and shape tools that power the next generation of “business operations.” The way the world views and does business is changing, and we are committed to leading this change responsibly.

Role Overview:

We are seeking a Senior Full Stack Engineer to lead the development of new products at MOON. This is a hands-on engineering role that requires deep experience across front-end (React) and back-end (preferably .NET/C#, though strong backgrounds in other modern frameworks like Node.js or Python are welcome).

You will be responsible for architecting and building scalable, microservices-based applications that deliver exceptional user experiences. A key expectation is a strong willingness to leverage AI tools throughout the development process (for coding, testing, documentation, and automation) and to embed AI-powered capabilities directly into our products to create smarter, more efficient solutions for our customers.

This is a highly collaborative, customer-centric role. You will work closely with product, design, and other engineers to ensure our platform is intuitive, secure, and capable of integrating with a variety of external systems.

Key Responsibilities:

• Lead the design and implementation of full stack features, combining React front-end development with back-end services in .NET/C# (preferred) or other modern languages and frameworks (e.g., Node.js, Python).
• Architect and deliver scalable, microservices-based systems deployed on cloud platforms (AWS, Azure, GCP).
• Design and optimize data models and integrations with SQL (PostgreSQL, SQL Server) and NoSQL databases.
• Build and maintain robust APIs (REST, GraphQL) with secure authentication and authorization (OAuth2, SAML, tokens, API gateways).
• Apply AI-assisted development tools to improve coding speed, testing efficiency, and documentation quality.
• Collaborate with cross-functional teams (product, design, and customer-facing engineers) to deliver intuitive, reliable user experiences.
• Identify opportunities to embed AI and automation features into MOON’s products to drive innovation and customer value.
• Ensure high code quality, performance, and security across front-end and back-end systems.
• Mentor and support junior engineers, contributing to architectural decisions and best practices.

Qualifications and Skills:

• Bachelor’s degree in Computer Science, Engineering, or equivalent experience.
• 7+ years of professional experience in full stack software engineering.
• Strong expertise in React (hooks, context, state management, modern patterns).
• Proficiency in .NET/C# other modern frameworks such as Node.js or Python <
