• Optimize the performance of Node.js applications, including memory usage, event loop efficiency, and handling of asynchronous code.
• Follow security best practices in API development to guard against vulnerabilities and ensure secure communication.
• Familiarity with Dev Ops practices, including deploying Node.js applications in cloud environments (e.g., AWS), and working with CI/CD pipelines such as Git Hub Actions for automation.

• Experience with Node.js
• Strong knowledge of RESTful API development
• Proficient in unit testing and automated acceptance testing (AAT)
• A proactive mindset with the ability to work independently within a small, dynamic team
• A natural curiosity and eagerness to learn and innovate

• Experience with AWS ECS and Lambda
• Familiarity with Open API, Git Hub Actions, Data Dog, and Kong Gateway

• Customer‑centric mindset: ability to align development decisions with delivering an excellent user experience.

• At Good Leap, there are always opportunities for team members to grow and advance within the company. As you outgrow your current role, we will support your development into new opportunities.
