About Rebel

Rebel has been helping people claim their corner of the internet since 1999. We’re on the cusp of a major rebuild; modern stack, cleaner UX, security by default and we’re honest about the rough edges we need to fix. If you’d rather ship than sit in meetings; if untangling gnarly systems, simplifying renewals, and making customers smile sounds like a good day’s work, you’ll like it here. This isn’t a beige enterprise treadmill. It’s a hands‑on, high‑leverage role to help turn a trusted 25‑year brand into the internet’s most human, competitive registrar.

About the Role

We are seeking an accomplished application developer with strong technical capabilities and a desire to make a difference to join our dynamic and agile development team.

At Rebel, we’re in the middle of a bold reinvention. We were early to market and established as a powerhouse in the domain registrar arena. Now we’re looking for someone who’s ready to help us take it further.

In this role, you will be instrumental in the development of our new systems as well as maintaining our legacy systems (with the goal of modernizing them). Our target stack involves nodejs, express, react and aws.

You will work on a multitude of projects as we revamp our website, applications and backend systems. As part of an agile team, you will play different roles with the goal of having a positive impact on customers and achieving key objectives.

• Mentor and foster the professional growth of team members by promoting a culture of knowledge sharing, collaboration, and continuous learning, empowering them to develop new skills and expertise.


• Collaborate with cross-disciplinary teams, including Engineers, product owners, Marketing, Customer Service and stakeholders, to design, build, and deliver successful, high-quality products that meet business and user needs.


• Develop and maintain end-to-end features across the entire technology stack, ensuring seamless integration and optimal performance at every stage of the process.


• Design, build, and optimize reusable UI components utilizing modern front-end technologies (Reac.) to create intuitive and engaging user experiences.


• Architect and develop robust back-end services and microservices using .NET and Node.js, ensuring scalability, reliability, and ease of integration with other systems.


• Implement best practices for clean, modular, and reusable code, ensuring that software components and modules are efficient, maintainable, and scalable for long-term use.


• Iterate on the design, testing, and implementation of features using agile methodologies, continuously improving and refining features based on feedback and performance data.


• Take full ownership of the testing, deployment, and observability of features, ensuring high-quality, secure, and bug-free releases with thorough analytics and performance tracking.


• Identify and implement cost-reduction strategies within our cloud environment, optimizing resources while maintaining high performance, reliability, and scalability.


• Stay at the forefront of industry trends and technological advancements, continuously evaluating and adopting new technologies, frameworks, and best practices to drive innovation within the team.
