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:

As a Full Stack Software Engineer, you will play a key role in building software solutions for the MOON platform. You will design and implement both front-end experiences in React and back-end services, with the flexibility to work across multiple frameworks and technologies. While we use .NET and PostgreSQL internally, we value talent and we don’t define our engineers by technology stacks. It is more important that you are adaptable and capable of picking up new tools quickly.

A critical expectation for this role is the heavy utilization of AI in the software development process. We are looking for engineers who are not only comfortable but enthusiastic about leveraging AI tools to accelerate coding, testing, documentation, and design, as well as creatively embedding AI into the product to deliver smarter, more efficient customer solutions.

Key Responsibilities:

• Design, develop, and maintain scalable front-end applications using React and modern UI patterns.
• Build and extend back-end services and APIs, preferably in .NET/C#, with the flexibility to adapt to other frameworks as needed.
• Collaborate with product managers and designers to deliver intuitive, performant, and user-friendly experiences.
• Integrate with databases (PostgreSQL, SQL Server, and NoSQL) and design data models that support secure and reliable workflows.
• Write clean, testable, and maintainable code, ensuring high code quality and coverage.
• Contribute to CI/CD pipelines, automated testing, and deployment processes.
• Leverage AI development tools (code generation, testing automation, documentation, monitoring) to maximize productivity and efficiency.
• Identify opportunities to embed AI-driven capabilities into the MOON platforms, delivering innovative features for customers.
• Troubleshoot and optimize performance across the full stack.
• Stay current on new frameworks, tools, and best practices to help shape our technical direction.
• Participate in code reviews, design discussions, and team knowledge sharing.

Qualifications and Skills:

• Bachelor’s degree in Computer Science, Engineering, or equivalent experience.
• 5+ years of experience as a Full Stack Software Engineer.
• Strong experience with React (hooks, context, state management, component-driven design).
• Proficiency in at least one back-end framework (preferably .NET/C#, but Node.js, or Python are welcome).
• Solid understanding of REST APIs, authentication/authorization, and API security practices.
• Hands-on experience with databases (PostgreSQL, SQL Server, or other relational/NoSQL systems).
• Familiarity with cloud services (Azure, WAS, GSP), containerization (Docker, Kubernetes), and CI/CD workflows.
• Demonstrated ability and willingness to heavily use AI in daily work, including coding, testing, documentation, and solution design.
• Strong problem-solving skills and ability to work independently in a fast-paced environment.
• Hands-on experience with microservices implementation and architecture.
• Excellent communication and teamwork skills.
• Practical experience working in Agile teams.
