What sets us apart is our in-depth understanding of each partner (being their best influencer!), addressing not only their needs but also capturing their essence.
Our partner is a fast-growing HealthTech company developing connected technologies at the intersection of hardware, embedded systems, IoT, AI and digital health . Their technology transforms everyday environments into intelligent health platforms, enabling seamless and continuous health monitoring.
We are currently looking for a Senior Embedded / Software Engineer to join their Engineering team and help build the embedded technologies powering the next generation of connected health products.
Mission:
As a Senior Embedded / Software Engineer , your mission will be to develop and evolve the embedded software and connected-device technologies at the core of the company's products, while contributing to the Python backend and cloud services that connect them. Your day-to-day will be approximately 60% embedded and 40% software .
This is a versatile, hands-on role. You will move between firmware, Linux-based platforms, backend and cloud depending on what the product needs, and when something fails across devices, screens or services, you will be the person who finds where the problem comes from: software, hardware or the integration between both.
You will be a senior technical reference for the team from the execution side : taking ownership of projects, solving complex problems, supporting more junior engineers and staying close to the code. You will work alongside the Head of Engineering, who leads the technical and architectural direction. This is not a Tech Lead or people management role.

- Contributing tocloud infrastructure, deployment pipelines and system monitoring.
- Investigating and troubleshooting complex issues acrossfirmware, software, connectivity, cloud and hardware integration, across the different platforms of the product.
- Takingend-to-end ownership of projects and features, from design and implementation through deployment and production.
- Driving continuous improvements in the software once the hardware is stable and robust.
- Working closely withProduct, Hardware, Backend, AI and Data teamsto turn product ideas into scalable technical solutions.
- Writing clean, maintainable and well-tested code following strong engineering practices.
- Supporting and guiding more junior engineers throughcode reviews and knowledge sharing.
What we need:
- 5+ years of professional software engineering experience, with solid experience in embedded systems. A very senior technical level and hands-on profile will be highly valued.
- Strong experience developing embedded software inC/C++.
- Solid experience withLinux-based embedded systems, Linux development environments andBash scripting.

- Experience with modern Python backend frameworks such asFastAPI, Django or similar, and withSQL / PostgreSQL.
- Strong understanding ofsoftware engineering best practices, including testing, code reviews and maintainable software design.
- Excellentdebugging, analytical and problem-solving skills, able to trace issues across hardware, software and integration layers.
- Ownership, autonomy and the ability to work across different layers of the stack, from embedded to backend and cloud.
- Professional English level.
