Electrical Engineer - Embedded Systems

Job DescriptionJob DescriptionDescription:n

CLYNK, an upstart technology and information player in the recycling space, is seeking an Electrical Engineer to join the CLYNK team.

n

The successful candidate will work within multi-discipline project teams to design, implement, and validate embedded electrical systems that power our high-volume Materials Recycling Facilities (MRFs). This individual will develop and support digital circuit designs, embedded controls, sensor integration, and low-level firmware for innovative products and systems used in redemption and recycling environments.

n

This role requires close collaboration with mechanical, manufacturing, and software teams to deliver end-to-end solutions from concept through deployment. You’ll support prototyping, field validation, and commissioning efforts, and be a key player in improving our existing platforms and enabling future technologies. Must be flexible for up to 25% travel across the Northeast (Maine, Connecticut, New York).

n

We are looking for a hands-on, self-starting engineer with a strong foundation in digital circuit design and embedded programming, and at least two years of practical experience.

n

As an Electrical Engineer, your work will directly shape how CLYNK processes, sorts, and tracks materials, helping to push the boundaries of redemption technology in support of a more sustainable future.
