Staff Software Engineer

Own the technical direction for complex, cross-cutting initiatives spanning device APIs and event pipelines, device lifecycle management, device transport and protocol infrastructure, and partner-facing platform capabilities.

Lead architectural design for medium-to-large initiatives, producing high-quality design documents that capture tradeoffs, constraints, and long-term implications — not just the chosen approach.

Define and evolve shared platform patterns, API contracts, and event schemas that are used by multiple teams across the department.

Anticipate medium-term architectural risks — 12+ months out — and work proactively to prevent them from negatively impacting the team or the platform.

Contribute to and influence department-wide technical standards, modernization guidance, and platform conventions — participating in tech councils, working groups, and cross-team design reviews as an active contributor, not a passive observer.

Lead delivery of foundational platform capabilities across the device ecosystem: device state and command APIs, device lifecycle management, event-driven pipelines, and the transport and protocol infrastructure that connects physical devices to the platform.

Build and evolve partner-facing platform components within SPX's Core Partner Platform: outbound command services, inbound event pipelines, authentication and authorization infrastructure, and integration patterns that scale across multiple partners.

Drive end-to-end delivery of large, multi-engineer initiatives with a high degree of autonomy — from technical design through implementation, validation, and production readiness.

Ensure systems you build and influence are observable, supportable, and operationally sound from day one — not as an afterthought.

Build frameworks, libraries, and components that are reusable across the team or department — and that are actually adopted and used by other engineers. The success of this work is judged on the size of problem solved and whether it genuinely reduces duplicated effort and accelerates delivery.

Make engineers around you noticeably more effective — through design reviews, code reviews, pairing, and direct coaching on architectural thinking and engineering craft.

Help engineers at all levels frame problems well, constrain scope appropriately, and develop sound technical judgment — not just deliver features.

Serve as a trusted technical resource for engineers across SPX, Device Platform, and teams around the organization who build on or depend on shared platform capabilities.

Drive technical alignment across teams that share platform dependencies — surfacing conflicts early, proposing resolutions, and ensuring shared systems evolve in a coherent direction.

Partner with the team's Architect on domain-level technical direction, contributing meaningfully to architectural decisions rather than passively consuming them.

Represent the team's technical interests in cross-team forums, dependency discussions, and platform planning conversations.

Translate architectural vision into executable plans that delivery teams can act on — bridging the gap between long-term platform direction and near-term delivery reality.

Establish and uphold high standards for production readiness, observability, and reliability across the systems you own and influence.

Contribute to incident response, postmortems, and the durable improvements that follow — treating operational quality as a first-class engineering concern.

Help define and operationalize SLAs, monitoring frameworks, and support models for partner-facing and shared platform services.

Use AI-assisted development tools as a consistent part of your engineering workflow — for drafting, debugging, refactoring, test generation, and documentation — while maintaining full architectural control and review discipline.

Model rigorous validation practices for AI-generated output: review for correctness, edge cases, security implications, and long-term maintainability before anything reaches production.

Help teammates adopt AI tools effectively — sharing workflows, prompting patterns, and validation approaches that raise the team's collective fluency without lowering engineering standards.

A Staff SE at Alarm.com is a technical leader whose impact is unmistakably felt beyond their immediate scope. The clearest signal is multiplier impact: a Staff SE's technical contributions, reusable patterns, and engineering judgment make the teams and systems around them measurably better. They drive initiatives of feature-team-level scope, are capable of seeing current problems and upcoming architectural improvements and driving toward solutions with minimal management support, and are a trusted voice in cross-team technical conversations.

The Staff SE operates via two complementary modes:

Depth — owning a technology, framework, or component that a meaningful number of other engineers build on, evangelizing it, and making it easy to use and extend; or

Breadth — being responsible for the technical direction of a broad set of code and sub-teams, setting a technical roadmap, identifying gaps, and making other engineers more efficient and productive through their projects, designs, and guidance.

Bachelor's degree in Computer Science, Engineering, or equivalent practical experience.

10+ years of backend software engineering experience, with a demonstrated track record of operating at Staff-level scope and impact.

Proven experience leading large, multi-engineer technical initiatives end-to-end — from architecture through delivery — with a high degree of autonomy and accountability for outcomes.

Demonstrated ability to define and evolve reusable platform patterns, shared libraries, or integration frameworks that are actually adopted and used by other engineers — not just built.

Strong architectural judgment: ability to reason about service boundaries, domain ownership, failure modes, versioning, and long-term maintainability — not just immediate implementation choices.

Deep proficiency in backend platform engineering: RESTful and/or gRPC APIs, distributed systems, event-driven architectures (Kafka or equivalent), and shared platform design.

Experience operating in environments moving from tightly coupled systems toward domain-aligned, independently deployable services.

Demonstrated ability to anticipate medium-term technical problems and drive toward solutions proactively — not just respond to issues as they surface.

Active participation in engineering leadership initiatives — tech councils, working groups, cross-team design reviews — with a track record of influencing other experienced engineers, not just consuming information.

Credibility working alongside architects and engineering managers on technically complex, cross-team initiatives — influencing direction without needing to be the final decision-maker.

Clear, positive buy-in toward AI-assisted development as an expected part of modern engineering work; this is not optional for this role.

Practical familiarity with AI-assisted development workflows — including the ability to use AI effectively for implementation, debugging, and documentation while maintaining validation rigor and architectural discipline.

Strong experience with.NET/C# and SQL Server; this is the foundation of Alarm.com's backend stack, though equivalent depth in similar ecosystems may translate well.

Experience building or evolving partner-facing APIs, external integration platforms, or shared internal platform capabilities consumed by multiple teams.

Hands-on experience with Kafka or similar event streaming infrastructure — including schema design, consumer patterns, and operational considerations at scale.

Experience with device-oriented systems, IoT platforms, device lifecycle management, or integration-heavy backend architectures — including transport protocols, device provisioning flows, and the challenges of connecting physical hardware to cloud platforms at scale.

Experience with microservice or domain-aligned architecture patterns, including domain analysis, service boundary definition, and incremental migration from monolithic systems.

Experience with observability practices, incident management, and production operations at scale — including defining monitoring frameworks and support models for externally consumed systems.

Experience using AI-assisted development tools (e.g. GitHub Copilot, Cursor, Claude Code) in a structured, disciplined workflow — including multi-file refactors, spec-driven development, and test-driven AI usage.

Familiarity with the Model Context Protocol (MCP) or other patterns for integrating AI agents with REST APIs and platform services.

Experience contributing to or leading department-wide technical standards, architecture decision records, or engineering working groups.

This role has broad technical scope across two closely connected platform areas. The Staff SE will own or co-own foundational capabilities spanning device APIs, device lifecycle management, and the transport and protocol infrastructure that connects physical devices to the platform — as well as the Core Partner Platform infrastructure within SPX that enables strategic partners to build reliably on top of Alarm.com's stack. The role carries visibility at the Director level and above, and the work has direct impact on Alarm.com's ability to scale strategic partnerships and evolve its device ecosystem.

Alarm.com is at a critical inflection point in its platform evolution. The shift toward PaaS partnerships, domain-aligned architecture, and a modernized device ecosystem requires engineers who can shape the technical foundations that dozens of teams build on — and who leave systems and organizations better than they found them.

The Staff SE hired into this role will help define how device data flows across the platform, how devices are integrated and managed at scale, how partners connect reliably to Alarm.com 's infrastructure, and how the engineering organization moves faster with more consistency and less rework. The right person will be a force multiplier in the truest sense — someone whose technical contributions, reusable patterns, and engineering judgment make the teams and systems around them measurably better for years to come.
