Purpose / Role Overview :

The purpose of this role is to design, develop, and deliver production-ready firmware for products, ensuring compliance with functional, regulatory, quality, and manufacturing requirements.

The ideal candidate will possess strong firmware design and development skills, with a proven track record of delivering firmware for commercial products from concept through to production.

Who you are:

We’re looking for a motivated and passionate person who has a strong interest in embedded software. You enjoy writing code, building quick prototypes and you have a good working knowledge of electronics circuits.

You’re organized, methodical and take pride in doing things well. You love debugging code, probing signals and always seek to understand the fundamental reason when things don't work.

You are capable of developing code from either a blank slate or building on an existing codebase. You understand the need for good documentation and don't see it as an impediment. You are a team player and like bouncing technical ideas with your colleagues.

• Full ownership of all embedded firmware development activities to deliver complete firmware solutions, from concept to final product.
• This is a hands-on role that involves requirements capture, code development & firmware testing.
