Edge Impulse is the enterprise platform for edge AI and TinyML; we make it easy to train and deploy machine learning for embedded applications. Our customers are mainly in the industrial, healthcare, and wearables spaces.
It's the best place I have ever worked. Our team includes several pioneers of edge AI. The company is a mix of the best parts of US and European culture, and are super open and transparent.
We are hiring a Technical Product Manager, Senior Full Stack Engineer, Customer Solutions Engineer, Solutions Engineering Manager, Sales Account Executive, and SDRs.

There's a list of MCUs here:

And some accelerators here:

This is just stuff that has support in Edge Impulse, but there are many other chips too.
For inference there's a whole spectrum of approaches that let you can trade off flexibility for performance. TF Lite Micro is at one end, hand-written Verilog is at the other.
Typically, flexibility is more important at the start of a project, while deep optimization is more important later. You wanna be able to iterate fast. That said, the flexible approaches are now good enough that you will typically get better ROI from optimizing your model architecture rather than your inference code.
I think the sweet spot today is code-generation, when targeting general purpose cores. There's also increasing numbers of chips with hardware acceleration, which is accessed using a compiler that takes a model architecture as input.
TinyML means running machine learning on low power embedded devices, like microcontrollers, with constrained compute and memory. I was supremely lucky in being around for the birth of this stuff: I helped launch TensorFlow Lite for Microcontrollers at Google back in 2019, co-authored the O'Reilly book TinyML (with Pete Warden, who deserves credit more than anyone for making this scene happen) and, ran the initial TinyML meetups at the Google and Qualcomm campuses.
You likely have a TinyML system in your pocket right now: every cellphone has a low power DSP chip running a deep learning model for keyword spotting, so you can say "Hey Google" or "Hey Siri" and have it wake up on-demand without draining your battery. It’s an increasingly pervasive technology.
TinyML is a subset of edge AI, which includes any type of device sitting at the edge of a network. This has grown far beyond the general purpose microcontrollers we were hacking on in the early days: there are now a ton of highly capable devices designed specifically for low power deep learning inference.
It’s astonishing what is possible today: real time computer vision on microcontrollers, on-device speech transcription, denoising and upscaling of digital signals. Generative AI is happening, too, assuming you can find a way to squeeze your models down to size. We are an unsexy field compared to our hype-fueled neighbors, but the entire world is already filling up with this stuff and it’s only the very beginning. Edge AI is being rapidly deployed in a ton of fields: medical sensing, wearables, manufacturing, supply chain, health and safety, wildlife conservation, sports, energy, built environment—we see new applications every day.
This is an unbelievably fascinating area: it’s truly end-to-end, covering an entire landscape from processor design to deep learning architectures, training, and hardware product development. There are a ton of unsolved problems in academic research, practical engineering, and the design of products that make use of these capabilities.
I’ve worked in many different parts of tech industry and this one feels closest to capturing the feeling I’ve read about in books about the early days of hacking with personal computers. It’s fast growing, tons of really hard problems to solve, even more low hanging fruit, and has applications in almost every space.
