Alarm.com is seeking a Principal Software Engineer to lead architecture and engineering for the emPower team, building IoT, smart home, energy management, HVAC, and connected-device control software. You will provide hands-on technical leadership, define architecture, mentor engineers, and drive scalable, reliable systems across cloud services, devices, mobile and web apps.

Sponsorship for new applicants is not available at this time.

Qualifications

Bachelor’s degree in Computer Science, Computer Engineering, a related field, or equivalent professional experience.
15+ years of professional software development experience.
Proven experience designing, building, and delivering complex software systems.
Strong object‑oriented programming skills; experience with C#/.NET or a similar object‑oriented language is required; direct C# and .NET experience would be a major plus.
Experience leading technical direction across teams and influencing architecture beyond a single project or codebase.
Experience mentoring engineers and helping develop people, practices, and reusable technical solutions.
Ability to select appropriate frameworks, architecture patterns, and technical approaches, then educate teams and drive adoption.
Strong analytical skills and a practical problem‑solving mindset.
Ability to lead and influence across teams without relying solely on reporting authority.
Ability to reason across the full product stack, including backend services, data stores, APIs, device integrations, and web/mobile user experiences.
Strong understanding of object‑oriented design, software development lifecycles, and long‑term maintainability concerns.
Excellent communication skills, including the ability to explain technical tradeoffs to engineers, product owners, and business stakeholders.

Responsibilities

Provide hands‑on technical leadership for systems spanning IoT device control, smart home automation, energy, HVAC, water, and connected‑device experiences.
Lead architecture and design for major software components, services, APIs, data flows, and integration patterns.
Help evolve existing monolithic systems into more modular, scalable, reliable, and maintainable systems.
Partner with product, firmware, platform, operations, and application teams to turn ambiguous needs into clear technical direction.
Mentor engineers at multiple levels and help raise the technical bar through design reviews, code reviews, technical guidance, and reusable patterns.
Drive cross‑team collaboration and execution across multiple technical domains.
Evaluate new technologies, frameworks, and methodologies where they can materially improve product capabilities or engineering outcomes.
Reason across the full product stack, including backend services, databases, APIs, web and mobile experiences, device integrations, automation logic, and operational tooling.
Be an expert on system architecture, functionality, data flows, operational processes, and the tools needed to operate production systems effectively.
Provide technical thought leadership for major software components, systems, and features, earning alignment and driving adoption across teams.
Exercise strong engineering judgment: know when to move quickly, when to invest in a robust platform capability, and when to avoid unnecessary complexity.
Bring your ideas. We want our engineers to collaborate on product development, not blindly build to a spec.
Other duties as assigned.
