Why we read it this way (8)
The title 'Senior Staff' is treated as Staff-level; the role's scope (cross-team protocol architecture, roadmap ownership, executive communication, mentoring) clearly supports Staff rather than Senior.
The role requires hands-on experience with at least one of Z-Wave, Matter, PowerG, or ZigBee — these are listed as a single interchangeable gate in the requirements section, so Z-Wave is the primary with the others as alternatives.
Grafana is listed under requirements with the qualifier 'such as', meaning observability tooling is a hard gate; Grafana is named as the canonical example with common alternatives (Datadog, New Relic, Prometheus) not explicitly named but implied by 'such as'.
C# and .NET are explicitly called out as 'a plus' in the requirements section, and SQL Server and cloud databases are similarly qualified — these are treated as preferred despite appearing in the requirements block due to the explicit 'a plus' language.
The Nice to Have section covers Thread/BLE/Wi-Fi/cellular, MQTT/HTTP/WebSockets/gRPC, TLS/DTLS/security, embedded C/C++, telemetry ingestion, and OTA strategies — all marked preferred.
Alarm.com's headquarters is in Tysons, VA (Washington DC metro area); the posting requires 4 days/week in-office, so remote=false.
The alt SOC 11-3021 is noted because the role has significant leadership, roadmap-setting, and executive communication duties, though the primary day-to-day work is hands-on architecture and implementation (15-1252).
No immigration sponsorship is available per the posting.
