Software Engineer

We're looking for a versatile software engineer - a jack of all trades - grounded in strong systems and low-level fundamentals. You'll work across backend services and occasionally the firmware that talks to them. The right candidate thinks in terms of how things actually work underneath the abstractions: memory, processes, protocols, signals. With that foundation, modern tooling (including AI assistance) covers the rest. We develop exclusively on Linux, so familiarity helps - but it's the kind of thing a strong engineer can pick up quickly.

A core focus is developing systems for modeling complex physical sites - floor plans, maps, and spatial layouts - used for tracking, alarms, and coordinated device behavior. You'll help create clean abstractions that allow many IoT devices to work together with unique behaviors, without fragile, one-off implementations.

This role is remote-friendly, with a preference for candidates located in or near Denver, CO for in-person collaboration.

What You'll Do

• Build and extend backend services in C# and Python that support device communication, data ingestion, site modeling, and user-facing features

• Work with IoT and LoRaWAN data flows, including tracking, alarms, and coordinated device actions across a site

• Reason about and improve tracking logic - RTLS pipelines, RSSI-based positioning, signal filtering, and related algorithms

• Develop, deploy, and troubleshoot on Linux (our platform runs there end-to-end)

• Occasionally jump into firmware (C/C++) to fix bugs, add small features, or debug device behavior end-to-end

• Maintain and extend web interfaces for industrial IoT applications (floor plans, maps, site layouts)

• Collaborate closely with a small engineering team to design, implement, and ship product-focused features

• Contribute to system and architecture design with an emphasis on clean, maintainable abstractions

Do you have experience in TypeScript?, Do you have a High school diploma or GED?, Strong backend development experience with C# and Python

• Working knowledge of C / C++, with the ability to read, modify, and debug firmware-style code

• Strong low-level fundamentals - memory, processes, threads, pointers, protocols - the kind of understanding that lets you reason about a system from the bottom up

• Comfort working in a Linux development environment (or the chops to ramp up quickly - we develop exclusively on Linux)

• Experience designing and consuming APIs

• Generalist mindset: willing and able to pick up unfamiliar layers of the stack to solve a problem, and effective at leveraging modern tooling (including AI) to do so

• Ability to work independently and take ownership of features

Nice to Have

• Experience with RTLS, RSSI-based tracking, trilateration/multilateration, or signal-processing/filtering techniques (Kalman filters, weighted averaging, etc.)

• Embedded firmware development experience (ARM Cortex-M or similar microcontrollers, UART/SPI/I2C, interrupts)

• Familiarity with networking concepts, protocols, and distributed systems

• Prior experience with industrial IoT, LoRaWAN, or embedded-connected systems

• JavaScript / TypeScript and modern web frontend experience

• Experience with cloud-based deployments, monitoring, or observability tools
