Senior Software Engineer
About The Position
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 HAX, you'll lead design and delivery of high-impact 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 move across the stack as the work demands: frontend, backend, data, infrastructure. 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.
Requirements
- Bachelor’s in Computer Science, Computer Engineering, a related field or equivalent work experience
- 6+ years of professional software development experience
- Strong frontend engineering skills with modern JavaScript/TypeScript frameworks (for example, React, Ember, Vue, or Angular)
- 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 comfortably across both modern and legacy framework codebases
- Fluency with the day-to-day toolchain of a modern engineer — version control (Git workflows), CI/CD, package managers, structured data formats (JSON, YAML), and observability tooling
- Experience designing reliable, scalable systems with attention to performance, resiliency, and maintainability
- Demonstrated testing depth across unit, integration, and end-to-end test layers
- Strong debugging and operational skills to diagnose and resolve production issues using logs, metrics, and traces
- Experience providing feedback to peers and influencing code quality through design and code reviews
- Track records of ramping into unfamiliar stacks and shipping production work in them
- Treats engineering as a craft that pursues mastery through deliberate practice, post-incident learning, and reflection on past decisions; comfortable revisiting and revising prior architectural choices when new information arrives
- Experience leading projects to completion and mentoring other engineers
- Proven ability to communicate and collaborate across product, design, and QA and drive technical decisions through delivery
- Experience scoping and decomposing ambiguoug problems into shippable increments
- Experience articulating tradeoffs explicitly (knowing when/when not to apply patterns)
Nice To Haves
- Experience working with enterprise-scale microservices architecture
- Familiarity with event-driven/distributed system design and distributed event streaming platforms (Kafka)
- Experience using AI-assisted development tools effectively while maintaining code quality and safety
- Familiarity with cloud-native infrastructure and containerized deployments (Docker + Kubernetes)
- Exposure to legacy-to-modern framework migrations
- Working knowledge of application security fundamentals (auth, authorization, input validation, secrets handling)
Responsibilities
- Lead and develop full stack 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
- Lead design and delivery of high-impact 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.
- Move across the stack as the work demands: frontend, backend, data, infrastructure.
