For a century, the answer to “what’s in the pipe right now” was a grab sample to a lab with results back hours later. We answer it every second.
Laminar is building human-centric self-driving factories: the ones made of stainless steel pipes and reactors, that make what the world eats, uses, and wears. Proprietary inline sensors read the chemistry in the pipe. Foundation models grounded in physics and chemistry reason about how close the process is to its target. Process control software acts on the answer through the plant’s automation system in real time. Laminar Insights shows what happened, why, and what it saved.
A Laminar line uses about 20% less water and 20% fewer chemicals and runs 15% faster, with quality protected. Productivity and sustainability improve together. We run across six continents at manufacturers like Coca-Cola, Unilever, and AB InBev, backed by tier-1 investors in Physical AI.
We’re a polymathic team of 50 in Somerville: hardware and software engineers, chemists, AI researchers, factory operators, and go-to-market wizards under one roof. Nobody here is waiting to be asked what to do. You’ll see the problem, propose the fix, and own the outcome. We believe in autonomy, ownership, and demanding excellence, and we hold each other to it. If that’s how you want to spend your time, come build the self-driving factory with us.
What You Will Do
-
Acquisition & Conditioning: Own the sensing signal chain, covering ADC acquisition and timing, filtering, integration and averaging strategy, and calibration.
-
Sensor Integration: Integrate new detectors and sensing elements as our sensor lineup evolves. Own integration, supporting board bring-up through production-ready drivers.
-
Noise Rejection: Get the real signal out of noisy environments. Tackle challenges like vibration, EMI, thermal drift, and more.
-
Firmware development: Develop firmware in Zephyr to interface with new detectors into our existing modular sensor stack
-
Calibration: Build the firmware side of calibration, including on-device coefficient storage, third party calibration procedures, and the final provisioning process for our sensors.
-
Device Connectivity: Ship drivers, OTA, and health monitoring for our sensors to carry data up to our Edge Gateway.
About You
-
4+ years of experience building embedded software for sensors or instrumentation.
-
Track record of owning the design, implementation, and success of significant components within a larger system.
-
Comfortable defining technical direction, taking ownership, and delivering in a fast-paced product iteration cycle.
-
Strong embedded C/C++ on microcontrollers with production Zephyr experience. You are fluent in devicetree, Kconfig, west, and the device driver model.
-
You have designed filters, tackled sampling and aliasing, and designed and debugged signal chains.
-
