Job description

Join Vonage and help us innovate cloud communications for businesses worldwide!

Vonage Applications:

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.

Why this role matters:

We are looking for an enthusiastic and curious Software Engineer to join the Unity Team. We are a small, collaborative team where every engineer makes a real impact.

The Unity Team is at the heart of Vonage Contact Center's (VCC's) AI and bot integration domain. We are the bridge between VCC and the world's most advanced conversational AI platforms - building gateways that let voice bots and digital LLM-powered agents seamlessly integrate into enterprise contact center workflows.

We are pushing the boundaries of what contact centers can do: connecting voice interactions to LLM providers, enabling scenarios for voice and digital channels and integrating multiple platforms for many business verticals. Our platform serves hundreds of thousands of users daily, and our work directly shapes the future of how businesses communicate with their customers.

Your key responsibilities:

• Developing and maintaining backend services in .NET as part of our bot integration and AI gateway infrastructure.
• Contributing to end-to-end features - from backend services to frontend components (in a full-stack DevOps culture)
• Working with real-time voice and digital protocols (SIP, WebSocket) that power live customer interactions.
• Participating in designing scalable microservices deployed on AWS.
• Contributing to code reviews and growing your skills alongside the team.

What you'll bring

Required:

• 1–3 years of commercial experience in backend software development with a strong focus on .NET (C#).
• Understanding of REST APIs and the fundamentals of distributed systems.
• Willingness and eagerness to work across the stack including frontend development (Vue.js).
• A growth mindset - positive energy, curiosity, and the desire to learn.
• Strong English skills.
• Ability to collaborate effectively with a global, distributed team.

Experience we consider a plus:

• Hands-on experience with any modern frontend framework (ideally Vue.js).
• Familiarity with AWS cloud services (ECS, DynamoDB, SQS, SNS, S3).
• Experience with messaging systems such as Kafka or RabbitMQ.
• Knowledge of containerization and orchestration (Docker, Kubernetes).
• Exposure to CI/CD pipelines for automated testing, building, and deploying applications.
• Familiarity with databases (MySQL, DynamoDB, MongoDB).

How you’ll benefit:

• Discretionary Time Off
• Private Medical Healthcare
• Pension scheme
• Ericsson support line
• Hybrid work
• Additional benefits and perks will be shared and discussed with you by the recruiter during the interview process
