Senior Embedded Software Engineer

Alicat Scientific builds high-performance mass flow and pressure instrumentation. The Senior Embedded Software Engineer develops and maintains firmware for flow and pressure instruments, from hardware bring-up through production, testing, calibration, and field support.

Responsibilities

Design and implement embedded C for our flow and pressure instruments: control loops, filtering, calibration routines, drivers, and hardware abstraction layers

Build and maintain communication interfaces and industrial protocols, along with bootloaders, firmware update, configuration, diagnostics, and logging

Work hands-on with Electrical Engineering during hardware bring-up, debugging at the register and signal level

Help build out our unit, integration, and hardware-in-the-loop testing and CI pipeline

Contribute to system architecture, design reviews, coding standards, and release practices

Partner with Product Management and Applications Engineering to turn customer requirements into workable technical scope, and support manufacturing test and field diagnostics

Preferred

A BS in Computer Engineering, Electrical Engineering, Computer Science, or a related field is valued
