About the Role
We are seeking a Senior Embedded Systems Engineer to own the electronics and firmware platform for a next-generation continuous sensing device.
This is a highly hands-on role spanning electronic architecture, schematic and multilayer PCB design, embedded firmware, sensing and wireless integration, power optimisation, bring-up and verification. You will translate laboratory prototypes into compact, reliable hardware designed for continuous operation.
The central challenge is balancing power, signal integrity, reliability, cost and future scalability within a tightly constrained form factor. You will have significant ownership of component selection, technical trade-offs, development standards and the path towards manufacturable designs.
About Us
We are a stealth, venture-backed and grant-funded deep-tech company developing a proprietary photonic platform for continuous, multi-marker molecular sensing. We are backed by a leading European venture fund, experienced health-tech investors and strategic operators, alongside significant grant funding from the EU.
Todayโs biochemical measurements provide isolated snapshots of dynamic biological processes. Our mission is to make these changes continuously measurable, transforming molecular data into timely, actionable insight.
Our platform brings the stability and multiplexing capabilities of advanced laboratory photonics into compact, scalable devices using miniaturised, low-cost and low-power electronics. We are initially applying the technology to health-focused applications, with the potential to reveal new insights into physiology, disease progression and treatment response.
As we move from core technology validation towards integrated product development, we are expanding a multidisciplinary team spanning molecular recognition, surface chemistry, biosensing, photonics, microfluidics and engineering.
Responsibilities
- Electronics architecture: Define and deliver a customised low-power platform, including processor selection, power management, memory, communications and firmware architecture.
- Schematic and PCB design: Design, review and iterate multilayer PCBs, selecting components and interfaces for a compact wearable form factor.
- Embedded firmware: Develop robust C/C++ firmware for microcontrollers, including peripheral drivers, device control, data handling and diagnostics.
- Sensing and communications integration: Interface with sensing, optical and wireless modules using standard analogue and digital interfaces.
- Cross-functional integration: Work with photonics, mechanical and microfluidics engineers to integrate the electronic subsystem into the wider device.
- Power and reliability: Optimise energy consumption, battery life, thermal behaviour, signal integrity and continuous-operation reliability.
- Hardware bring-up: Lead PCB bring-up, bench testing, debugging, fault isolation and verification of hardware-firmware interactions.
- Prototype development: Build and iterate functional prototypes, test fixtures and engineering tools that accelerate system development.
- Prototype to manufacture: Support design for manufacture and test, component lifecycle decisions, supplier engagement and repeatable assembly.
- Development frameworks: Establish design documentation, test methods, acceptance criteria and reusable hardware and firmware standards across the platform.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet โ that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right โ and where to focus when applying.
Technical Leadership Scope
For a candidate with deeper product-development experience, the role may also include setting the electronics roadmap, managing specialist design partners, mentoring future hires and contributing to intellectual-property and manufacturing strategy.
