Tasks and responsibilities
At Sinch, we're on a mission to empower developers and businesses to build meaningful connections. Our In-App Calling platform is a key part of that vision, enabling seamless, reliable voice and video communication directly within our customers' applications on a global scale.
We're looking for a Senior Software Engineer who is passionate about building the resilient, high-performance cloud infrastructure that powers millions of these real-time conversations. This isn't just about maintaining backend systems; it's about architecting the future of how people interact.
As a core member of our agile team, you'll take on complex challenges at the intersection of distributed systems, cloud-native architecture, and real-time communication.
You will:
Design, develop, and scale the critical C#/.NET services that form the backbone of our real-time communication platform.
Take full ownership of your code, from initial design and testing to deployment on Kubernetes in AWS and ensuring its reliability in production.
Champion best practices in software architecture, code quality, and testing, helping to continuously improve our systems and processes.
Leverage the full power of AWS and Kubernetes to build observable, resilient, and automated systems that can handle a global user base.
Work in a tight-knit, cross-functional team of engineers and product managers to solve complex problems and drive the technical direction of our platform.
Education, experience and personal characteristics
You have significant professional experience building and running production backend systems, with deep expertise in C# and .NET Core.
You possess a strong DevOps mentality, are comfortable with CI/CD pipelines, and believe that the best code is clean, testable, and maintainable.
You are a natural collaborator with excellent communication skills, eager to share your knowledge and learn from others.
Nice to have:
Hands-on work with Kubernetes and AWS in a production environment.
Building and scaling distributed, service-oriented architectures.
Databases like MySQL, MSSQL, or Redis.
VoIP protocols (especially SIP) or real-time media services like Asterisk.
Other languages like C++, Python, or Kotlin - we value a willingness to learn!
You're a product-minded engineer who sees the big picture but also loves to dive into the details. You thrive on complexity and have a passion for understanding systems from the inside out, digging deep into the codebase to solve tricky problems and master the architecture. You're motivated by a challenge and take immense pride in the quality and reliability of your work.
