Job description

Alarm.com provides the leading cloud platform for smart security and IoT, powering millions of home and business experiences. Our systems integratedevices, cloud services, APIs, and event-driven workflows into a unified ecosystem used by internal teams and external partners around the world.

About the Team

This role sits at the intersection of two strategically important areas of Alarm.com's engineering organization: Strategic Partner eXcellence (SPX) Device Platform.

SPX establishes the partner enablement function for Alarm.com's highest-value PaaS integrations. The team architects and maintains the Core PartnerPlatform — shared edge services, event pipelines, authentication infrastructure, and integration patterns — that allow strategic partners to build reliably on top of Alarm.com's stack.

Device Platform builds and evolves the foundational shared capabilities that underpin Alarm.com's connected device ecosystem. This spans the full arc ofhow devices are modeled, integrated, and managed on the platform — from the APIs and event pipelines that expose device state and commands, to thelifecycle management flows that govern how devices are provisioned and maintained, to the transport and protocol infrastructure that connects physicaldevices to the platform at scale.

These two areas are deeply connected. The partner-facing platform depends on the device platform being reliable, well-bounded, and evolvable. An SE IIin this space contributes meaningfully to both — building and maintaining the platform capabilities that teams and partners depend on, and growing theirtechnical ownership over time.

The team is led by an Engineering Manager and supported by a senior Architect. The SE II hired into this role will work in close partnership with seniorengineers and the broader team, taking on increasing ownership of technical work within a well-supported structure.

The Role

We are hiring a Software Engineer II to contribute to the SPX and Device Platform domains as a capable, independent individual contributor.

At Alarm.com, the SE II carries a clear mandate: independently complete technical tasks with good quality, take meaningful ownership of their work, andgrow steadily toward leading small projects end-to-end. This is a hands-on engineering role. The SE II writes production code, participates in design andcode reviews, contributes to project delivery, and develops the technical and process fluency needed to operate with increasing autonomy.

Projects span device APIs, event pipelines, device lifecycle management, and partner-facing platform capabilities. The SE II is expected to completeassigned work with high-level direction, seek out the information they need to succeed, and communicate proactively about progress and blockers.

Success in this role requires solid programming fundamentals, growing familiarity with Alarm.com's architecture and processes, and the professionalcommunication skills to collaborate effectively across engineering, QE, PM, and operations. This is a growth role — the right person will be on a cleartrajectory toward Senior SE, demonstrating increasing independence, ownership, and technical judgment over time.

What You'll Do

Technical Delivery & Code Quality

• Write and maintain high-quality backend code across the SPX and Device Platform domains, including device state and command APIs, event pipelines, device lifecycle management flows, and partner-facing integration components.
• Complete assigned tasks and features independently with high-level direction, seeking out information and context as needed to deliver good outcomes.
• Participate actively in code reviews — both receiving feedback and providing thoughtful, constructive review on peers’ work.
• Ensure the code you write is correct, well-tested, and maintainable — treating documentation and testing as first-class engineering concerns, not afterthoughts.
• Debug and troubleshoot issues across environments, applying systematic reasoning to identify root causes and deliver durable fixes.

Project Ownership & Delivery

• Take meaningful ownership of your work across the full development cycle — from design through implementation, testing, and release.
• Lead small, single-engineer projects or well-scoped workstreams with minimal guidance, including producing design documents, managing day-to-day tasks, and communicating project status and milestones clearly.
• Contribute meaningfully to moderately complex, multi-engineer projects — understanding your scope, executing reliably, and raising blockers early.
• Communicate proactively about progress, risks, and estimates — avoiding surprises for your team and manager.

Technical Growth & Collaboration

• Develop working knowledge of Alarm.com's architecture, codebase, and the systems owned by SPX and Device Platform — understanding which teams own which components and how they interact.
• Build familiarity with Alarm.com's development processes — spec/design, build, QE, ops — and understand how engineering, QE, PM, and PgM work together to deliver software.
• Assist with onboarding of more junior engineers, answering specific technical and process questions about projects you have worked on.
• Participate in design discussions and contribute technically sound ideas within your area of expertise.

Operational Awareness

• Write code that is observable and supportable — with appropriate logging, error handling, and consideration for how issues will be diagnosed in production.
• Participate in incident response and postmortem processes, contributing to the team's understanding of what went wrong and how to prevent recurrence.
• Apply production readiness standards consistently in your work.
• Use AI-assisted development tools as a consistent part of your engineering workflow — for drafting, debugging, refactoring, test generation, and documentation — while maintaining full review discipline over AI-generated output.
• Validate AI-generated code rigorously before it reaches production: review for correctness, edge cases, security implications, and long-term maintainability.
• Treat AI tools as
