About the Role

Microair Avionics is looking for a Senior Firmware Engineer to lead the design, development, verification, and certification of embedded firmware for DO-178C DAL-A/B airborne systems.

This is a hands-on technical leadership role based at our Indore facility, working closely with engineering teams across Australia, the US, Ireland, and India.

You will own firmware architecture and implementation across the development lifecycle—from requirements and low-level design through coding, verification, structural coverage, certification evidence, and SOI audits.

The role will also involve leading and mentoring firmware engineers, establishing coding and design standards, conducting technical reviews, and representing Microair in technical discussions with customers, DERs, and certification authorities. F-440-03_A_Job_Description_-_Se…

What You'll Bring

We are looking for a senior engineer who combines deep embedded firmware expertise with safety-critical software engineering discipline.

You should be comfortable taking ownership of firmware architecture and implementation while also working at the certification level—requirements traceability, verification evidence, structural coverage, audits, findings, and compliance.

This role is particularly suited to someone who wants to operate as a technical authority and engineering leader, rather than purely as an individual contributor.
