We’re looking for an experienced firmware engineer to help develop and refine a cutting-edge IoT system that will transform care for senior patients. In this role, you will contribute to the development of our AI-enabled, sensor-driven devices by extending firmware and applications, bringing up new hardware components, and addressing firmware issues through code reviews and ticket triage. You’ll work across the entire firmware stack from low-level bus protocols to higher-level transport layers to deliver high-impact features that enhance the patient and caregiver experience.
Key responsibilities include embedded development in C/C++ within a multi-threaded environment, collaborating with hardware teams to debug and ship production-quality devices, and supporting the full software release cycle. Candidates should have at least 3 years of professional experience in software development (including 2+ years of writing production-ready code), strong programming skills in C/C++, and experience with Linux kernel development. Preferred candidates will also have experience with Yocto Linux, MQTT, Speech SDKs, and TI Industrial Radar, along with a bachelor’s degree in computer science or equivalent. Strong communication skills and the ability to work both independently and collaboratively are essential.
Key Responsibilities
- Design, develop, and continuously improve high impact features for our customers.
- Embedded development in C/C++, in a multi-threaded environment; delivering high quality code for our devices.
- Work on delivering new features which are aligned with the total software release cycle.
- Work across the firmware stack, be it at the low bus level or at the transport layer to debug, resolve, and fix issues.
- Work closely with hardware to help ship high quality products.
-
Communicate ideas to the team and collaborate in oral and written form.
- 3+ years of professional software development experience.
- 2+ years experience writing and maintaining production ready code.
-
Linux kernel development experience.
- 3+ years of experience in the full software development life cycle, including device bring-up, code reviews, debugging, source control, and testing.
- Development experience in one or more of the following: Yocto Linux, MQTT, and Speech SDKs.
- Experience with any TI Industrial Radar.
-
Bachelor’s degree in computer science or equivalent.
Cairns Health is redefining home healthcare by integrating AI-driven behavioral care with passive remote monitoring. Our digital companion, Luna, provides real-time medication reminders, symptom checks, and social engagement while using radar-based sensing to track vitals like heart rate, breathing, and sleep—without requiring wearables. By delivering proactive, in-the-moment interventions, we enhance clinical outcomes, reduce healthcare costs, and improve patient and caregiver experiences.

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.
