Company

blueOASIS is a young and growing company focusing on developing sustainable solutions for ocean protection. blueOASIS is working on four scopes: numerical analysis for offshore renewables and ships, underwater acoustics, smart ocean modelling and sensorisation, and digital twinning. We are also developing a disruptive Ocean Digital Twin platform: www.hydrotwin.ai . Our team is now looking for an Electronics and Embedded Systems engineer to work directly in hardware developments to support Hydrotwin and R&D goals.

Role description:

Electronics and Embedded Systems engineer with a solid foundation in electronics, embedded software, and hardware integration. The role is focused on the development and integration of blueOASIS sensing systems across multiple platforms. Work will include embedded firmware development, sensor interfacing (acoustic and non-acoustic), data acquisition, and system integration of sensors such as hydrophones, temperature, salinity, dissolved oxygen, cameras, and other environmental instrumentation. The engineer will contribute to building reliable, platform-agnostic solutions capable of operating on buoys, USVs, UUVs, and other marine assets. Close collaboration with the acoustics, AI and software teams is expected to ensure coherent hardware-software integration for real-time, power-constrained systems.

Responsibilities:

·  Design, prototype, and validate electronic hardware systems

·     Interface and integrate multiple sensors (acoustic and non-acoustic) into unified hardware platforms

·     Support integration of sensing systems into buoys, USVs, UUVs, and other marine platforms

·     Develop and maintain embedded firmware for sensing and data acquisition systems

·     Implement communication interfaces for sensor and system integration

·     Support power management design and optimisation for low-power, field-deployed systems

·     Perform system testing, debugging, and validation in laboratory and field environments

·     Collaborate closely with teams to ensure reliable hardware-software integration

·     Contribute to technical documentation, test reports, and system integration guidelines

Expertise needed:

·  Background in electronics engineering, embedded systems, mechatronics, or a related field

·     Solid understanding of analogue and digital electronics fundamentals

·     Experience developing embedded firmware in C/C++ or similar languages

·     Familiarity with schematic design and PCB layout tools

·     Experience with laboratory testing and debugging tools (e.g., oscilloscopes, multimeters, logic analysers)

·     Ability to debug hardware and firmware issues in integrated systems

·     Experience with version control systems (e.g., Git)

Added value (these skills are a plus, not required):

·   Underwater acoustics

·     Marine or offshore systems

·     Integration of systems into autonomous or robotic platforms

·     Low-power system design for field-deployed devices

·     Environmental sensor integration

·     Mobile, wireless, or satellite communication systems

·     Field deployments in harsh or remote environments

·     AI/ML

·     Edge computing for vision

General conditions:

• Work in Torres Vedras or Faial office.
