Job summary

Alarm.com is seeking a Software Engineer II (Backend‑leaning Full‑stack) to join our Access Control team in Kraków. You will design, develop, and maintain backend services powering our access control platform, with exposure to cloud APIs, data models, and the device communication layer to hardware like panels, readers, and locks.

You will work across the stack, contributing to web front‑end when needed, and collaborate with product managers, hardware engineers, and other software teams.

Qualifications

• Bachelor’s or Master’s degree in Computer Science, Computer Engineering, 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.

Responsibilities

• 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.
