“What if your code didn’t just run on a device... it lived inside one?”
We’re building implantable medical devices that listen to the body and respond in real time, changing lives by treating chronic pain with unprecedented precision. This isn’t theoretical. It’s already in the hands (and spines) of patients across the world.
But to keep pushing boundaries, we need someone who can write firmware that works flawlessly inside the human body.
The Opportunity
You’ll take ownership of our next-generation platform - an ultra-low-power implant that’s undergoing a microcontroller transition to meet new global cybersecurity standards. This isn’t a ground-up rebuild or a hands-off maintenance role - it’s surgery on a live system that thousands of people rely on, with real-time constraints and no room for error.
The day-to-day? You’ll contribute to embedded design for Class III, safety-critical medical devices, navigate bare metal firmware and RTOS implementations, and help drive our internal migration to ARM Cortex-based platforms .
But Here’s Where It Gets Interesting
- You’ll shape the direction of the firmware stack on a product that’s literally inside someone’s body
- You’ll define the future state of how we integrate cybersecurity, encryption, and over-the-air upgradability into systems that cannot fail
-
You’ll mentor others shoulder-to-shoulder, as someone who genuinely wants to level up the team around you
- Write embedded C for bare-metal systems or RTOS environments (we're transitioning to one on ARM Cortex MCUs)
- Understand the trade-offs in ultra-low-power, resource-constrained environments and take pride in optimising every byte
- Are used to writing for safety-critical or regulated systems - medtech is ideal, but aerospace, automotive, or defence translate well
- Know your way around I2C, SPI, UART, and the gritty reality of talking to hardware
-
Believe documentation isn’t just compliance - it’s part of building something that lasts
Smart, grounded people solving real problems. No egos. No passengers. Just a team of engineers who want to build the best tech possible - and get it into the hands of people who need it most. We call it the “spark” - a mindset that blends curiosity, humility, and a bias for doing good work.
Sydney-based. 3 days on-site is the norm, but we're pragmatic - come in when the hardware needs you, stay flexible otherwise.
If you’ve ever wanted your work to matter more - this is it.
Firmware that lives in the body. Real-world outcomes. And a team that gets it. If that sounds like your kind of challenge, email Thaís at thais@theonset.com.au
Senior Embedded Software Engineer
@ Embedd 
What we're looking for
At embedd.it, we power hardware-software integration in embedded devices. We turn fragmented semiconductor chip data into configurable digital twins, then deterministically generate code, tests, and documentation – making integration faster, cheaper, and resilient to supply chain shocks.
We’re looking for a true legend – someone with abstract thinking and deep expertise in low-level software development. You’ll build vendor-agnostic tooling for MCU and peripheral integration to solve hardware-software integration once and for all. We work at the intersection of embedded systems, code generation, compilers, and machine learning. It’s your chance to help redefine how low-level development is done.
Responsibilities
- Drive the architecture of the driver structures and system layout
- Define scalable patterns for cross-architectural integration across bare-metal, Zephyr, Linux, and other environments
- Deconstruct complex SoC device trees and translate hardware descriptions into structured internal models for automated reasoning
- Partner with the ML team to shape data and annotation models for AI-driven data-extraction tooling
Qualifications
- 5+ years of experience in embedded systems development, including bare-metal and RTOS-based systems
- Proficiency in C/C++
- Familiarity with firmware configuration, SoC bring-up, and system-level debugging
- Hands-on experience with code generation tools, or low-level compiler/decompiler/emulator technologies
- Strong background in embedded toolchains: compilers, linkers, debuggers, and build systems
- Python or scripting for automation and tooling is a plus
- Experience with functional-safety standards is a plus
Why embedd.it?
- Dynamic, venture-backed team of engineers challenging the status quo 🚀
- Work at the intersection of embedded systems, code generators, compilers, and ML 🤖
- Unusual challenges requiring out-of-the-box abstract thinking 🧠
- Competitive compensation: cash + equity 💰
- Remote work possible 🌍
About Us
embedd.it is a UK-based startup reinventing embedded development. Our platform transforms unstructured semiconductor data into structured digital twins, enabling automatic generation of drivers, tests, and documentation. We're building a single, traceable source of truth to make integration fast, vendor-agnostic, and future-proof.
