Software Engineer II (.NET)

EBS is a rapidly expanding, entrepreneurial technology company and part of Alarm.com. Alarm.com is the leading cloud-based platform for smart security and the Internet of Things. More than 7.6+ million home and business owners depend on our solutions every day to make their properties safer, smarter, and more efficient. We’re innovating new technologies in rapidly evolving spaces including AI, video analytics, facial recognition, machine learning, energy analytics, and more. 

The Access Control (AC) team is a blend of full-stack engineers, leaning backend, who build the platform that businesses rely on to secure and manage physical access to their properties. Our services span the full journey of an access control system — from cloud APIs and event pipelines down to the communication layer that talks directly to panels, card readers, and smart locks in the field. Some examples include enabling multi-site businesses to manage access from a single dashboard, delivering real-time access activity and history to property managers, and keeping thousands of controllers in the field configured, updated, and in sync with the cloud. We’re seeking a Software Engineer II (Backend-leaning Full-stack) who is passionate about building reliable, scalable systems that bridge cloud software and real-world hardware and wants to see their code open doors — literally — for businesses around the world. 

As a Software Engineer II on the Access Control team, you will design, develop, and maintain the backend services that power our access control platform — from cloud APIs and event pipelines down to the systems that communicate with physical controllers and readers in the field. While the role is backend-leaning, you’ll work across the full stack, contributing to our web front end when features call for it. You’ll work alongside experienced engineers who will support your growth as you take on increasing ownership of features and systems. 

• →Build and Deliver: Design, develop, and maintain scalable backend services, APIs, and data models that power our access control platform. 
• →Bridge Cloud and Hardware: Contribute to the device communication layer that connects our cloud platform to access control hardware — panels, readers, and locks — including device configuration, firmware update, and real-time event processing flows. 
• →Contribute Across Layers: Develop features across the full stack, including web front-end features (Ember.js), when projects require it. 
• →Own the Lifecycle: Take part in the entire development lifecycle, from requirements gathering through deployment and production monitoring. 
• →Get Hands-On: Work directly with real access control hardware to develop, test, and debug device integrations. 
• →Ensure Quality: Write unit and integration tests, validate features before release, and monitor production performance. 
• →Balance Trade-offs: Exercise good judgment — know when to iterate quickly and when to build for scale, robustness, and maintainability. 
• →Collaborate: Work closely with product managers, hardware/device engineers, and other software teams across time zones. 
• →Grow and Share: Learn from senior engineers through code reviews, design discussions, and pairing — and share your own knowledge as the team grows. 
• →Continuous Improvement: Bring your ideas! We want our engineers to collaborate on product development, not blindly build to a spec. 

• Bachelor’s or Master’s degree in Computer Science, Computer Engineering, or a related field, or equivalent professional experience. 
• 2+ years of professional software development experience. 
• Strong object-oriented programming skills; experience with C# is a plus. 
• Experience developing backend services and HTTP APIs (REST or similar). 
• Experience with database design and development (SQL). 
• Experience with creating and maintaining unit tests; familiarity with integration testing and CI/CD is a plus. 
• Familiarity with a modern JavaScript framework such as Ember.js, Angular, or React. 
• Experience working with hardware, IoT, or device development is a plus. 
• Good communication skills.
