Position Overview

At Onsights, our engineers build and maintain high-performance software systems that enable real-time video analytics and smart surveillance for brick-and-mortar environments. As a Senior .NET Developer, you’ll lead the development of robust Windows-based applications that power our edge and near-edge data collection systems. This role requires deep experience with the Microsoft .NET ecosystem, including WPF, WinForms, and UWP where applicable.

We're looking for an engineer with a strong background in building portable applications—systems that can operate in constrained, disconnected, or semi-connected environments—and implementing remote monitoring capabilities. Experience building Windows service applications is a must. You should also be comfortable integrating with Azure Entra, IoT hubs, and other cloud-based services that support on-premises components. Familiarity with .NET CI/CD pipelines is also required for maintaining high-velocity, reliable software delivery.

 

What You Will Work On

• Build and maintain .NET desktop applications using WPF, WinForms, and UWP, supporting both full-scale and portable edge deployments
• Design and implement Windows service applications for background operations such as ingestion, synchronization, and health monitoring
• Develop portable, installable software that supports remote monitoring, diagnostics, and telemetry reporting across fielded systems
• Integrate on-premise applications with Azure Entra ID, Azure IoT Hub, and other cloud-based platforms for authentication, configuration, and data streaming
• Work with video management systems like Milestone XProtect, Genetec, and Avigilon to automate video export, analysis, and system state capture
• Develop and maintain robust test coverage using NUnit, and ensure system stability through consistent test automation
• Build and maintain deployment tools and pipelines, contributing to .NET-focused CI/CD workflows
• Collaborate with infrastructure, backend, and hardware teams to ensure seamless integration and monitoring across distributed environments

 

Responsibilities

• Lead design, development, and support of key desktop and background services across the .NET stack
• Build software components that enable secure data flows between on-prem devices and the cloud
• Implement integrations with identity and access services such as Azure Entra for authentication and authorization scenarios
• Develop and support CI/CD pipelines tailored to Windows-based deployment targets and .NET service/app builds
• Assist with deployment planning, troubleshooting, and optimization of on-site and remotely managed installations
• Document technical designs, workflows, and system behaviors to support long-term maintainability and onboarding

 

Skills & Talents

• Expert-level proficiency in C# and .NET Framework (4.5+) / .NET 6+
• Hands-on experience with WPF, WinForms, UWP, and Windows services
• Strong understanding of portable software architectures and remote monitoring patterns
• Experience integrating with Azure Entra (formerly Azure AD) and cloud-based services such as Azure IoT Hub or similar
• Practical experience building and maintaining CI/CD pipelines for .NET projects using tools such as GitHub Actions, Azure DevOps, or TeamCity
• Proficiency with unit/integration testing using NUnit and related frameworks
• Familiarity with secure telemetry, background task scheduling, and health reporting patterns in resource-constrained environments
• Strong analytical, communication, and documentation skills

 

Desired Qualifications

• Familiarity with Video Management System platforms such as Milestone XProtect, Genetec, or Avigilon
• Knowledge of streaming protocols (e.g., RTSP, ONVIF) and media processing workflows
• Understanding of edge/cloud hybrid architectures and telemetry optimization
• Experience with Git, deployment automation, and managing structured software releases
• Ability to work across both Windows and Linux environments is a plus

 

Minimum Experience

• Bachelor’s degree in Computer Science, Engineering, or a related field
• 5+ years of software engineering experience in the .NET ecosystem
• Proficiency in C# and .NET Framework (4.5+) / .NET 6+ and other programming languages
• Understanding of agile development and methodologies
• Experience with containers and Kubernetes
• Experience building and using APIs and SDKs
• Familiarity of various communication architectures and protocols (e.g., REST, gRPC)
• Familiarity with various design patterns (e.g., MVC, MVVM)
• Demonstrated experience developing and deploying WPF/WinForms/UWP applications and Windows services
• Proven integration experience with Azure Entra, IoT/cloud services, and CI/CD pipelines
• Experience with telemetry, remote monitoring, and diagnostics tools for deployed systems
