Software Engineer II

Centennial, CO  ·  Full-Stack  ·  Backend Focus

Some engineers go deep on the server and never look up. Others gravitate to the client and lose interest the moment something touches a database. The engineers we're looking for do both — and they're more curious about the seam between the two than they are about either side alone.

At Alarm.com, a feature isn’t shipped until it runs end-to-end from server, through an API, and is accessible a homeowner's phone or browser. In this role, you'll help build all of it — with an emphasis on the server-side work that makes the rest possible.

Alarm.com is one of the leading IoT platforms in North America. Millions of homeowners and businesses rely on our software to secure, monitor, and automate their properties — and our engineers help build and maintain the systems that make that happen at scale.

This position is on the Customer Experience (CX) team — a full-stack group embedded at the core of Alarm.com's mobile and web apps. CX owns the moments that matter most to customers: getting them up and running on the platform, giving them the tools to manage their accounts, and finding ways to make the overall experience smarter and more intuitive over time.

As a Software Engineer II, you'll own features end-to-end. That means designing the server-side logic, shaping the API contract, and then following the work into the client surfaces where users experience it — Android, iOS, or web. You won't be handed a spec and told to execute — you'll be expected to have opinions about how things should be built and to defend them.

If you're coming in strong on the backend and looking to deepen your client-side skills on one platform, this role is built for exactly that trajectory.

• →Design and implement server-side services and APIs that power features across Alarm.com's product ecosystem
• →Own features completely: scoping, implementation, testing, deployment, and production verification
• →Write clean, well-structured code that other engineers can read and maintain without explanation from you
• →Design for the full problem — edge cases, failure modes, and error conditions, not just the happy path
• →Contribute to client development on either Android, iOS, or web — you'll focus primarily on one platform, with exposure to others over time
• →Participate in code reviews that meaningfully raise quality, not just catch style issues
• →Collaborate across teams to define solutions that meet both business and technical needs
• →Engage with the full development lifecycle, from early requirements through post-ship monitoring and support
• →Bring your perspective to product decisions — we want engineers who think about what we're building, not just how
• →Use AI tools where they genuinely improve your work — and share what's working with the team; we value engineers who are thoughtful adopters, not reflexive ones
• →Other duties as assigned 

• Bachelor's in Computer Science, Computer Engineering, a related field, or equivalent work experience
• 2+ years of professional software development experience
• Strong object-oriented programming fundamentals: C# or Java experience is a plus
• Solid experience with SQL databases — schema design, query optimization, index strategy, and reading query execution plans
• Comfort with the full development lifecycle: writing tests, deploying safely, monitoring production health, and responding when things go wrong
• Curiosity about how the full stack works — genuine interest in following a feature from the server through to the client that delivers it

Don't check every box? That's okay — we'd still encourage you to apply. Strong engineers come from a lot of different paths, and we care more about depth of thinking and patterns of impact than a perfect resume match.

• Hands-on experience with at least one client platform: Android (Kotlin/Java), iOS (Swift), or a front-end framework such as React, Angular, Vue, or Ember — or a strong, demonstrated interest in learning one
• Familiarity with microservices architecture and distributed systems design
• Experience with event-driven architecture and messaging technologies (Kafka is a plus)
• Exposure to high-availability, high-throughput service design patterns
