About the role

Castelion Corporation seeks a Senior Electronics Design and Analysis Engineer to design and validate hypersonic defense systems. You will translate system requirements into electrical schematics, select components, and create PCB layouts for rugged environments. You will perform thermal, structural, and vibration analyses using FEA tools (e.g., ANSYS/COMSOL), collaborate with mechanical, manufacturing, and supplier teams, and help drive designs to production.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
