We are looking for
A Senior .NET Software Engineer to join the C4I and Cyber division in Modi'in.
Do you get excited about building systems that truly matter? Are you the kind of developer who thinks in architectures, not just code? Come join a team that develops and maintains critical defense infrastructure and high-performance monitoring systems - working across the full stack, from backend services to polished desktop and mobile interfaces, in a secure air-gapped environment where quality and reliability are everything.
In this role you will
Build robust backend services and infrastructure using .NET Core and .NET Framework
Design and implement advanced desktop and mobile interfaces using WPF and MAUI.NET
Facilitate complex integrations with peripheral hardware via SDKs (e.g., cameras, sensors) and manage high-volume MQ message flows
Architect solutions for multithreading and real-time data processing challenges
Operate within a Scrum framework to deliver secure, air-gapped software solutions
Requirements
3+ years of .NET development experience
Proven expertise in WPF and MAUI.NET
Experience with REST and SOAP APIs and asynchronous programming patterns
Hands-on experience with hardware integration via SDKs - an advantage
Experience with message queue systems (e.g., IBM MQ) - an advantage
Proficiency in English at a professional working level
Strong problem-solving skills with a passion for performance optimization and clean architecture
* This position is open to both women and men
**Only relevant applications will be answered
