Software Engineer
VMS Integrations & AI Services
Are you eager to be at the forefront of innovation within Milestone’s cutting-edge Video Management System?
Are you passionate about building production-grade software that connects AI services with real-world video management workflows? Do you enjoy working across desktop clients, web interfaces, backend APIs, integrations, and operator-facing features? If so, we want you to join our innovative team.
Location: Copenhagen, Denmark (Hybrid) – or Madrid office. Remote options available for the right profile.
About the Role
We are looking for a Software Engineer – VMS Integrations & AI Services to lead the development of the integration between our VLM-as-a-service platform and Milestone XProtect, while also helping us build an open, flexible integration layer for other Video Management Systems.
In this role, you will help bring our VLM capabilities into the daily workflows of security operators – designing and implementing integrations that are easy to use, easy to deploy, and valuable in real operational environments. You will work on XProtect Smart Client integrations, web components, backend APIs, and production services that allow operators to interact with VLM results, investigate events, retrieve insights, and use AI assistance as part of their existing VMS experience.
This is a role for an engineer who can drive projects end to end: understand the problem, design the technical solution, implement it, test it, deploy it, monitor it, support it, and improve it based on feedback from users and customers.
You will also contribute to Level 2 support activities, helping diagnose complex customer or deployment issues, supporting production incidents, and turning learnings into better product, tooling, documentation, and automation.
What You Will Do
XProtect Integration Development: Lead the development of the integration between our VLM-as-a-service platform and Milestone XProtect, including Smart Client workflows, backend integration points, and operator-facing features.
Smart Client & Operator Experience: Build features that support the daily needs of security operators, helping them access AI-generated insights, search video content, understand events, and interact with VLM results directly from their VMS environment.
Open Platform Integration Layer: Design the integration to be modular, extensible, and easy to adapt to other VMS platforms beyond XProtect.
Backend API Development: Develop and maintain backend APIs and services, primarily using Python, to connect VMS environments with our VLM service securely and reliably.
.NET Development: Build and maintain .NET-based components, including integrations, plugins, client-side extensions, service components, or tooling required for XProtect and Windows-based environments.
End-to-End Delivery: Own features from requirements and technical design through implementation, testing, deployment, monitoring, and production support.
Testing & Validation: Create and execute automated and manual tests covering integration behavior, API reliability, performance, edge cases, deployment scenarios, and operator workflows.
L2 Support & Documentation: Provide Level 2 support for production deployments, create technical documentation, integration guides, and troubleshooting material to make the solution easier to operate.
What You Bring to the Team
Technical Skills
Strong proficiency in .NET / C# for production software development, including integrations, plugins, desktop-client extensions, and Windows services.
Develop using new AI tool stacks (e.g. Claude, Codex) to accelerate time to release.
Full stack experience with Python for APIs, automation services and web development using frontend technologies such as TypeScript, React, or Angular.
Demonstrated ability to design and implement REST APIs, service-to-service integrations, and secure API communication.
Understanding of authentication and authorization concepts, including API keys, tokens, OAuth-style flows, and certificates.
Cloud experience with AWS, GCP or Azure, including deploying, operating and troubleshooting production services, APIs, and/or integrations to cloud services.
Familiarity with containerization (Docker), CI/CD pipelines (GitHub Actions, Azure DevOps, etc.), and observability practices (logging, metrics, tracing).
Knowledge of video management systems, surveillance workflows, or VMS operator applications is a strong plus. Experience with Milestone XProtect or MIP SDK is highly relevant.
Familiarity with AI inference services, VLMs, LLMs, or video analytics is a plus; deep model development experience is not required.
Experience
Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related field.
6+ years of hands-on software engineering experience, with strong .NET / C# production experience.
Track record of delivering production software end to end – from design and implementation through release and support.
Experience building backend APIs, integration services, or distributed systems.
Experience working in Agile environments with a focus on continuous delivery and production quality.
Experience in L2/L3 production support, incident analysis, or customer troubleshooting.
Background in enterprise customer integrations, partner SDKs, or platform ecosystems is a plus.
How You Will Make a Difference
You are pragmatic, autonomous, and delivery-oriented. You take ownership of ambiguous technical problems and turn them into robust, production-ready software. You understand real user workflows, not just isolated services, and you care about the experience of the security operators who rely on the tools you build.
