 * Experience developing automated verification environments
 * Experience with code coverage tools and test reporting
 * Experience supporting avionics, flight controls, embedded controls, or mission-critical systems
 * Experience working with hardware-in-the-loop, system integration labs, or production test environments

Ideal Candidate

The ideal candidate is a hands-on software test engineer with strong Python skills and experience verifying safety-critical embedded software. Strong candidates will be comfortable writing automated test scripts, building regression frameworks, supporting unit and system-level testing, troubleshooting embedded systems, and documenting test results in a regulated engineering environment.

Candidates from aerospace are preferred, but candidates from other safety-critical industries such as automotive, defense electronics, medical device, robotics, or embedded controls may also be considered.

Applicants should be prepared to discuss their Python experience, automated test frameworks, requirements-based testing experience, embedded systems background, and comfort level with a coding exercise.

## Description

We are seeking an Avionics Software Test Engineer to support verification of safety-critical flight software. This role will focus heavily on Python-based automated verification testing, requirements-based software testing, regression testing, unit/system-level testing, test tool development, and embedded hardware/software troubleshooting.

The ideal candidate will have aerospace, defense, automotive, medical device, or another highly regulated safety-critical software testing background. Strong Python coding ability is required, and a coding exercise may be part of the interview process.

Responsibilities

 * Support verification of safety-critical flight software
 * Develop Python-based automated verification test scripts
 * Create and maintain automated regression testing frameworks
 * Develop code coverage and software testing tools
 * Develop test cases for system-level and unit-level software testing
 * Support embedded hardware/software integration and troubleshooting
 * Document software design issues, test results, and anomalies
 * Work with engineering teams to resolve test failures and design issues
 * Support avionics production, integration, and verification activities
 * Contribute to improvements in software verification processes, test automation, and test environments
