Description
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. Our Home Automation Experience (HAX) team owns the full home automation domain at Alarm.com including devices, device groups, rules, schedules, scenes, and automation-related notifications, for both customers and dealers, across web, mobile, and the backend services that make it all work. Alarm.com is a smart-home-as-a-service platform — our products reach end customers through a network of professional security and smart-home dealers who install, configure, and support our systems, which means HAX builds for two distinct audiences with very different needs. If 'intuitive, accessible, reliable home automation' is the kind of problem you want to spend the next several years on, this is a good place to do it.   As a Senior Software Engineer on the HAX Team Automation Pod, you'll lead design and delivery of high-impact automation features end to end, from partnering with Product Management and Quality Engineering, mentoring engineers around you, to shaping technical direction in design reviews and architectural decisions. You'll focus primarily on backend development and data, infrastructure for all of our automation features including rules, schedules, and more.   Alarm.com is one of the few places you can build consumer products that ship at a consumer scale across this kind of technology surface (wireless, software, hardware/device) without changing companies. Engineers here go deep in their area and stay curious about everything else.   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 the possibility to work remotely occasionally. KEY RESPONSIBILITIES Lead and develop software for a wide variety of platforms and technologies.   Take part in the entire project life cycle , from requirements development to deployment with heavy cross-team collaboration   Engage in the research, evaluation, and application of new technologies and methodologies to solve challenging project goals   Write coherent, organized code. Ideal candidates must be comfortable working on a complicated  codebase  with high levels of abstraction   Exercise good judgment . Know when to work quickly, and when to build a robust solution   Work hard and be flexible : we have quick development cycles, evolving requirements, and lots of cross-team collaboration   Bring your ideas ! We want our engineers to collaborate on product development, not blindly build to a spec   WHAT SHOULD YOU BRING? Bachelor’s in Computer Science, Computer Engineering, a related field or equivalent work experience   6+ years of professional software development experience   Strong backend engineering skills building and maintaining HTTP APIs/services (REST and/or GraphQL)   Deep working knowledge of object-oriented design, SOLID principles, and common design patterns, with a track record of applying them to real architectural decisions (Experience with C#, .NET Core is a plus)   Solid database fundamentals including schema design, query optimization, indexing, and migration strategy   Contributed&nb
