  • Requirements Verification: Assist in the development of verification plans and procedures to ensure that low-level requirements are met.
  • Requirements Analysis: Analyze requirements for completeness, consistency, and correctness. Identify and resolve ambiguities or conflicts.
  • Collaboration: Work closely with system engineers, software architects, and developers throughout the software development lifecycle.
  • Documentation: Create and maintain clear, concise, and accurate requirements documentation in accordance with DO-178C guidelines.
  • Change Management: Participate in the requirements change management process, assessing the impact of changes and updating documentation accordingly.
  • Tool Proficiency: Utilize requirements management tools to manage requirements, traceability, and verification activities.

 

Education/Experience

  • Bachelor's degree in Computer Science, Computer Engineering, Aerospace Engineering, or a related field.
  • 7+ years of experience in software requirements engineering, specifically within a safety-critical environment.

 

Qualifications: The requirements listed below are representative of the knowledge, skills, and/or abilities required.

  • Strong understanding of the DO-178C standard, particularly related to requirements processes (DAL-A experience highly preferred).
  • Proven experience in decomposing high-level requirements into detailed, verifiable low-level requirements.
  • Experience creating and maintaining requirements traceability matrices.
  • Familiarity with requirements management tools (e.g., Polarion, Jama Connect, DOORS).
  • Excellent communication, collaboration, and problem-solving skills.
  • Ability to work independently and as part of a team.

 

Preferred Qualifications:

  • Experience with flight control systems or other aviation software.
  • Experience working in an Agile development environment.
  • Familiarity with model-based systems engineering (MBSE) practices.
  • Experience with static analysis and code coverage tools.
  • Master's degree in a related field.
  • Experience working in a startup environment and a fast-paced environment.
  • Familiarity with scripting languages (e.g., Python) for automating requirements tasks.

 

Salary Range: $100k - $130k

The actual salary offered is dependent on various factors including, but not limited to, location, the candidate’s combination of job-related knowledge, qualifications, skills, education, training, and experience.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
