Our company LiftAI is currently looking for a Firmware Engineer to join our team. We provide services that help support the elevator industry.

One of our offerings is an affordable sensor based solution that is installed on the elevator car top and sends telemetry about trips the elevator makes and other statistics around the trips.

Our platform is currently CircuitPython based. Engineers that have DSP experience and are interested can send their resume to adam at liftai dot com and I will provide followup information about the position. We're a fully remote company and open to anyone that can work within the contiguous US timezones.

Very interesting to hear about CircuitPython being used in the industry. I had thought it’s largely a hobbyist/ prototyping framework much like its upstream MicroPython. Out of curiosity, does your team implement all logics and math in Python, or is it a mix of C/Python? Has the platform posed any memory management challenges?

Signal processing. Sounds so sober after this AI hype. Maybe a good thing to get into!

No, it's obsolete like all math and ChatGPT is already killing pure mathematicians! DevSecMLPromptOps is where it's at.

Textbooks: Oppenheimer and Schaffer, Whalen, Skolnik, a digital filters book and then advanced books on advanced signal processing (array processing, adaptive filters, etc.)

Have fun with it!

May I add Steven Kay's Fundamentals of Statistical Signal Processing volumes to your already great textbooks recommendations.

thanks. sounds dope

I don't have the words to describe the fact that between you and the person you replied to, just recommended a masters degree worth of textbooks to some strangers inconspicuous comment. I mean, if someone could read and understand all the textbooks you two listed, they could get a research level radar position.

It's safe to assume that this person, along the rest who clicked on the thread may already have an appropriate background, pursuing or have obtained a degree in EE/CS/Math, that will allow them to self study Signal Processing. Or at least are aware there's a lot more to AI than ChatGPT.

The math behind ML are of similar difficulty yet when there are thousands of grifters promising your average front-end wevdev AI expertise in N number of videos, no one bats an eye.

Unfortunately, the barrier to research level positions is much higher than simply having the capability of going through an arbitrary list of textbooks: a number of publications in large relevant conferences or journals, e.g. ICASSP, IEEE Transactions on Wireless Communications, is what will make you an attractive candidate for them.

I thought "minimal job board" was like, minimal UI, simple and clean. I didn't know it meant very few jobs.

As someone with a specialty in signal processing: it's a good thing I'm a generalist.

embrace the noise I say . . .

I love the idea of very-niche job boards! Right now there are very few jobs on it, which makes it not-so-useful for job hunters. I think you could improve it by adding a bunch more jobs manually. Then when there is an audience I imagine companies will actually be interested in adding some jobs themselves. You're probably already aware this is a two-sided market, and you suffer from the cold start problem. I've bookmarked it and will try to come back :)

Thanks for the feedback and for checking it out!

Expected this to be a PCB

There are far more signal processing jobs than that. Raytheon alone has dozens of signal processing jobs openings.
