We are experts in domain names and the products that make the most of them. This helps our customers showcase their ideas, stories, services and contributions to the world.

Our manifesto: Be Thoughtful, Be Simple, Be Brave.

Role Overview

As a Senior JavaScript Full Stack Developer, you’ll lead the design and delivery of high-impact initiatives that power Rebel’s domain and hosting platform—building customer‑facing experiences and the services behind them. You’ll work across the stack—React on the front end and Node.js (with some legacy .NET) on the back end— with strong ownership from discovery through deployment and support.

You’ll partner closely with Product and cross‑functional teams to translate complex requirements into scalable, secure solutions, while raising the bar on engineering practices through thoughtful architecture, clean code, testing, and observability.

You’ll also mentor teammates, help drive technical direction, and contribute to a culture of continuous improvement and learning.

What You’ll Do

• Lead and drive technical initiatives across cross‑functional software development and operations teams, ensuring alignment with business objectives and technical excellence.
• Translate complex business requirements into comprehensive, scalable technical solutions, considering platform architecture, network infrastructure, software components, and security protocols.
• Mentor and foster the professional growth of team members by promoting a culture of knowledge sharing, collaboration, and continuous learning.
• Collaborate with cross‑disciplinary teams, including Engineers, Product Owners, Marketing, Customer Service, and stakeholders, to design, build, and deliver successful, high‑quality products.
• Develop and maintain end‑to‑end features across the entire technology stack, ensuring seamless integration and optimal performance.
• Design, build, and optimize reusable UI components utilizing modern front‑end technologies (React) to create intuitive and engaging user experiences.
• Architect and develop robust back‑end services and microservices using Node.js and .NET, ensuring scalability, reliability, and ease of integration.
• Implement best practices for clean, modular, and reusable code, ensuring software components are maintainable and scalable long‑term.
• Iterate on design, testing, and implementation using agile methodologies, continuously improving based on feedback and performance data.
• Take ownership of testing, deployment, and observability, ensuring secure, high‑quality releases with analytics and performance tracking.
• Identify and implement cloud cost‑reduction strategies while maintaining performance, reliability, and scalability.
• Stay current with industry trends and evaluate/adopt new technologies, frameworks, and best practices to drive innovation.
• Experiment with and leverage emerging AI technologies to enhance team performance and productivity.
• Participate in active system support, bug fixing, and incident resolution as needed.

What You Bring

• 8+ years of professional software development experience with deep hands‑on work with modern application stacks (Node.js, React).
• Proven track record of leading technical teams through complex projects, providing guidance, mentorship, and fostering a collaborative environment.
• Expert‑level JavaScript/TypeScript proficiency with modern ES6+ features.
• Strong Node.js and Express.js development experience and RESTful API design expertise.
• AWS cloud platform expertise, including hands‑on experience with serverless architectures.
• Cloud system design experience including microservices, event‑driven architectures, and distributed systems.
• Strong experience with Scrum/Agile methodologies, including hands‑on leadership and sprint‑based delivery.
• Experience with legacy system modernization and migration strategies.
• Working knowledge of .NET Framework and/or Java for legacy system maintenance.
• Strong command of Git and collaborative development workflows.
• Experience with CI/CD pipelines and automated testing strategies.
• Experience with Infrastructure as Code (CloudFormation, CDK, or Terraform).
• Container technologies (Docker, ECS/EKS is a plus).

The opportunity to work in an atmosphere that truly rewards hard work and creative thinking. We offer a competitive salary, benefits, and opportunities for growth and advancement within our company.
