Full-stack Software Engineer (C#, JavaScript)

Our Applications business unit focuses on delivering a suite of advanced communication tools designed to enhance customer engagement. From cloud contact centers to feature-rich unified communications solutions, our Applications team is dedicated to providing businesses with the tools they need to streamline operations and improve customer experiences.

We are an established team driving the innovation of our company’s core audio-call infrastructure. Our current mission is the new development of high-performance services that power real-time audio streaming for external processing, recording services, and external API integrations.

In this role, you will focus on building new, scalable features from the ground up. While we value full-stack capability, your primary impact will be in Backend and Cloud Engineering using .NET and AWS (ECS/EKS).

You will take ownership of the end-to-end development of new audio-processing logic and the APIs that expose these capabilities to the rest of the organization.

This is a hybrid role, offering the flexibility to work most of the time remotely. However, certain tasks will require in-person collaboration with team members. You should be prepared to attend on-site meetings (Tel-Aviv) occasionally to support key project milestones and ensure successful outcomes.

• Backend Expertise: 3+ years of professional experience in software development, with a deep focus on C# and the .NET ecosystem.
• Frontend expertise: Working experience with JavaScript
• Containerization & Cloud: Hands-on experience building and scaling services within AWS, specifically using ECS or EKS.
• Systems Engineering Mindset: A proactive attitude toward building new products from scratch, with a focus on high-quality code and scalable design patterns.
• Communication: Strong English skills and the ability to collaborate effectively in a distributed, multicultural environment.

Experience we consider a plus:

• DevOps & Scripting: Experience with CI/CD automation and scripting (e.g., Python, Bash) to streamline development and deployment.
• Performance Analysis: Familiarity with tools and techniques for profiling and optimizing .NET applications in high-load environments.
• Node.js Knowledge: Ability to contribute to or integrate with Node.js-based services.
