Senior Engineer, Architecture and Infrastructure Test

About the role

The role defines and delivers advanced validation for aerospace hardware. It ensures X-BAT reliability through rigorous test systems.

Software engineers turn product ideas into working code. Engineers work in small teams, review each other's work, and ship in small batches. Most teams follow agile practices such as sprints and daily standups. Engineers also write tests, fix bugs, and improve performance. The field values clear communication as much as technical skill. Engineers spend part of every week on planning, code review, and debugging, not just writing new code. The ability to explain a technical decision in plain words separates strong engineers from the rest.

Key facts

What you'll do

Automated test sequences in Python ensure scalability, efficiency, and repeatability for validation workflows.

Custom fixtures using relays, PLCs, PCBAs, and harnessing integrate and support hardware testing.

Cross-functional design reviews drive design-for-testability improvements for aerospace hardware.

Technical mentorship guides junior engineers and develops Shield AI hardware test engineering expertise.

Requirements

B.S. in Electrical Engineering or a related STEM field is mandatory for this position.

3+ years of industry experience in hardware design and test engineering or equivalent experience with advanced degrees is required.

Demonstrated expertise in electrical design, mechanical engineering, and software principles as applied to hardware test systems is required.

Proven ownership drives projects from concept to execution and delivers results in fast-paced, high-stakes settings.

A team-first mindset upholds high standards for yourself and others while solving complex technical challenges.

Track record of working hard, being a trustworthy teammate, holding yourself and others to high standards, and being kind to others is required.

US Citizenship is required due to security clearance requirements.

Practical notes

This role is based in Dallas, Texas, and may require onsite presence as needed.

Typical interview steps

Hiring for engineering roles usually starts with a recruiter screen, followed by one or two technical rounds. Candidates often solve a coding problem, discuss past projects, and answer system design questions. Some loops include a take-home task. Final rounds typically cover team fit and give candidates a chance to ask questions. Interviewers look for how you break down an unfamiliar problem, not just whether you reach the answer. Practicing a few problems aloud and reviewing your own past projects are the best preparation.

Good to know

Hardware test engineering in aerospace defense relies on precise validation of electrical and mechanical systems.

Python scripting is commonly used for test automation and data analysis in this field.

Tools like PCB design software and CAD platforms support the development of test fixtures and interfaces.

Harsh environment testing methods such as HASS, ESS, and HALT ensure system robustness.

Mentorship plays a key role in growing team capability and maintaining high standards.

Questions to ask

Good questions to ask the employer in the interview: what does success look like in the first six months, how is the team structured, what is the current biggest challenge, and how are decisions made. Asking about growth paths and the review process is also well received. Employers expect questions, and good ones show preparation.

Career growth

Engineering careers usually progress from individual contributor to senior, staff, and principal levels. Some engineers move into management and lead teams of five to twenty people. Others stay on the technical track. Growth follows demonstrated impact, not tenure alone. A typical engineering ladder has clear levels with defined expectations for scope, quality, and mentorship. Moving up usually requires owning outcomes end to end rather than completing assigned tickets.
