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 Senior Software Engineer (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 Senior Software Engineer on the Access Control team, you will design, develop, and optimize 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.   Alarm.com values working together and collaborating in person. We are building a new team in Krakow. Our employees work fully from the office with possibility to work remotely occasionally.   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: Build and improve 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. Lead: Drive technical projects end to end — make architectural decisions, guide design reviews, and ensure scalability, security, and performance. Mentor & Set Standards: Serve as a technical mentor and role model for the growing Kraków team — onboard new engineers, mentor junior and mid-level engineers through code reviews, design discussions, and pairing, and raise the bar for code quality. 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. Balance Trade-offs: 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. Continuous Improvement: Contribute to a culture of innovation by bringing new ideas and technical improvements to the team.   What You Bring Bachelor’s or Master’s degree in Computer Science, Computer Engineering, or a related field, or equivalent professional experience. 5+ years of professional software development experience, with proven success in delivering complex projects. Advanced object-oriented programming skills,
