Senior Network Engineer

Role Description

As our Senior Network Engineer, you will design and own the network infrastructure that connects building controls, sensors, gateways, data centers, and other operational technology to Motion.cloud.

Your mission is to make connectivity boring: reliable, observable, secure, and scalable across everything from a single building to complex campuses and distributed customer portfolios.

This is not an HVAC operations role. HVAC controls, building automation systems, meters, sensors, and other field devices are endpoints on the networks you will design and support. You will be responsible for making sure those endpoints can communicate reliably through local networks, fiber, cellular, Starlink, LoRaWAN, wireless backhaul, and other communications infrastructure.

You will design network topologies, develop connectivity and redundancy strategies, plan fiber and wireless links between facilities and data centers, troubleshoot difficult RF and WAN issues, and establish the standards we use to deploy and support connected infrastructure at scale.

You will work closely with Motion.cloud Engineering, customer IT teams, controls contractors, installers, carriers, and technology partners to ensure that data can reliably move from the field to Motion.cloud.

The Profile

You are a network engineer who likes environments where the answer is not simply, “plug it into the existing LAN.”

You are comfortable walking into a site and figuring out how to connect a mechanical room in one building to infrastructure three buildings away, whether the right answer is fiber, cellular, Starlink, LoRaWAN, or a wireless backhaul.

You think in diagrams. You want to know where the device is, what it is connected to, how traffic gets from there to Motion.cloud, what happens when the primary connection fails, and how we will know something is wrong before the customer does.

You are equally comfortable discussing VLANs and routing with a customer’s IT team, antenna placement with an installer, LoRaWAN signal quality with an IoT engineer, and connectivity requirements with a controls contractor.

When data stops arriving, you do not stop at “the sensor is offline.” You work the problem from end to end: device, RF, gateway, switch, firewall, carrier, VPN, Internet connection, and cloud.

You are looking for a high-impact role where you can establish the networking standards and architecture behind a rapidly growing fleet of connected customer infrastructure.
