TrapDtek is a start-up company based at Innovation RCA, we are developing wearable rescue indicators that can be paired with a new innovative energy harvesting system to optimize emergency services operations when finding missing persons.
Role Description
We are seeking a loT Energy Systems Engineer with strong expertise in antenna design (circuity), RF systems, and energy harvesting power electronics to lead the development of a minimum viable prototype (MVP) of a novel wireless device. The role focuses on designing and validating a feasible proof-of-concept system, demonstrating the integration potential between the antenna subsystem (within the RF-activated wearable) and an independent energy harvesting and battery management circuit.
You will be responsible for advancing the concept from design to a working prototype that validates both the RF performance and energy autonomy of the system. This position blends applied research with practical prototyping and system optimization.
Key Responsibilities
- Aid the design and build of a functioning MVP prototype that demonstrates core system feasibility- including an operational antenna system and a separately functional energy harvesting and storage unit (looking at a combined system that incorporates 3 different systems).
- Define the technical architecture and experimental framework to validate performance metrics such as harvested energy levels, antenna efficiency, power transfer, and system scalability.
- Design and simulate antennas optimized for the target frequency range and physical constraints of the MVP prototype.
- Develop and test RF matching networks and evaluate antenna integration into the prototype’s mechanical structure.
Energy Harvesting & Power System Prototyping
- Design and implement a standalone energy harvesting and power management system capable of charging and powering low-power electronics.
- Experiment with various harvesting modalities (RF, solar, vibration, thermal) to determine optimal energy sources for the application.
- Design battery management and charge circuits suited for micro-power conditions and duty‑cycled operation.
- Analyse system power budgets, conversion efficiency, and storage stability.
Outcome Goals
- Aiding in delivery of an early MVP prototype where both the antenna and energy harvesting subsystems operate independently yet validate overall system feasibility.
Qualifications & Ideal Candidate
- Hold a Bachelors/ and or Masters in electrical engineering, chemical engineering, design engineering, geomatics, or similar.
- Have experience working on projects that involve circuit/ battery design and optimization
- Be located in London, UK and commit to on‑site development
- Be willing to partake in field trials outside of London (all travel expenses would be covered for off‑site work)
- Must be British National OR hold a Graduate Route Visa that permits you to work
- Hours: looking for either subcontract or a part‑time employee, minimum contract 3-6 months.
