Senior Software Engineer, Embedded Systems

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.

We are looking for a Senior Embedded Software Engineer to own signal processing and firmware of Laminar’s process-aware sensors. This is a hands-on technical role at the intersection of embedded systems, digital signal processing, and sensing methodology. You will implement new detectors and sensing elements, own the signal data from end to end, and work directly with Hardware and ML teams to get the visibility into the industrial processes we need.

\n 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.

• Comfortable with analog: ADCs, gain, references, grounding, and noise.

• Testing heavy, pushing for unit tests, hardware mocks, CI, and collecting realistic data.

• Experience with optical and electrical sensing and emitters.

• Experience productionizing new sensing methodologies, from prototype to deployed product.

Benefits

• Direct impact on product and culture.
• Comprehensive benefits package including Medical, Dental, Vision, Life Insurance, Disability, Transportation benefit, Health and Wellness benefit, and more.
• 401k plan with employer matching
• Equity
• Competitive salary and bonus opportunities.
• Dynamic and inclusive work environment.
• Opportunities for growth and professional development.
• Access to Greentown Labs' extensive network of cleantech startups.

Our Interview Process

1. Phone screen with Laminar Head of Ops or Recruiter (15-20 minutes)

2. Intro call with Hiring Manager (30 minutes)

3. On-site interview, including short tour of GTL, overview of tech, and interview/presentation with the Hiring Manager and a few team members. Depending on the role, a skills exercise that should take no longer than an hour to prep, would be sent ahead of time. We record your skills exercise to share with any team members who could not join the interview and/or with Founder's ahead of their Founder's Interview. If you are not local, we can conduct this virtually.

4. Finalists for Full-Time positions will have a Founder’s Interview in-person

Final steps:

Two professional references are requested, ideally one from your current organization and one who served as your Manager

If an Offer Letter is extended, a Background check is conducted

A recent study from LinkedIn showed that most women apply to jobs only when they meet 100% of the requirements, whereas men will hit the apply button if they hit 60%. Laminar (formerly H2Ok) is committed to building a diverse and inclusive team. So, to the women and nonbinary folks out there feeling unsure if you're a perfect fit, we strongly encourage you to apply! If you're ready to play a key role in scaling a game-changing company that’s transforming the industrial sector and advancing sustainability, we want to hear from you!
