Human Factor Engineering information

What is human factor engineering?

Human Factor Engineering, also known as ergonomics, is the discipline focused on understanding how people interact with systems, products, and environments. It aims to design processes, tools, and spaces that optimize human well-being and overall system performance. By taking into account human abilities and limitations, Human Factor Engineers help reduce errors, increase efficiency, and improve safety and user satisfaction in various industries such as healthcare, aviation, and manufacturing.

How does a human factors engineer typically collaborate with cross-functional teams during product development?

Human Factors Engineers work closely with designers, engineers, product managers, and sometimes marketing teams to ensure that products are user-friendly and meet ergonomic standards. They often participate in design reviews, conduct user research, and provide feedback to integrate human-centered principles into the development process. Effective collaboration involves frequent communication, presenting user testing results, and advocating for design adjustments based on user data. This teamwork is crucial for creating products that are both effective and safe for end users.

What are the key skills and qualifications needed to thrive as a human factors engineer, and why are they important?

To thrive as a Human Factors Engineer, you need a solid background in human-computer interaction, ergonomics, and cognitive psychology, typically supported by a degree in engineering, psychology, or a related field. Familiarity with usability testing tools, data analysis software (such as SPSS or MATLAB), and design systems is often required. Strong analytical thinking, user empathy, and effective communication skills help you collaborate with multidisciplinary teams and advocate for user-centered design. These abilities are crucial for creating safe, efficient, and user-friendly products or systems that meet both user needs and organizational goals.

What is the difference between Human Factor Engineering vs Human Factors Specialist?

AspectHuman Factor EngineeringHuman Factors Specialist
CredentialsEngineering degree, certifications in ergonomics or human factorsDegree in psychology, human factors, or ergonomics; certifications preferred
Work EnvironmentDesign labs, engineering teams, product development settingsResearch facilities, consulting firms, healthcare, or corporate environments
Industry UsageProduct design, aerospace, automotive, healthcare devicesUsability testing, user research, safety analysis
Common Search IntentDesign-focused, technical solutionsResearch and usability evaluation

Human Factor Engineering primarily involves applying engineering principles to design systems and products that optimize human interaction. In contrast, Human Factors Specialists focus on researching and analyzing user behavior to improve usability and safety. Both roles often collaborate but differ in their core approach: engineering versus research and analysis.

Are human factor engineers in demand?

Human factor engineers are in increasing demand as organizations focus on user-centered design, safety, and usability across industries such as healthcare, aerospace, and technology. They often require skills in ergonomics, human-computer interaction, and relevant certifications, with job growth driven by the need to improve product safety and user experience.

What does a human factor engineer do?

A human factor engineer studies how people interact with systems, products, and environments to improve safety, usability, and performance. They analyze user behavior, conduct ergonomic assessments, and design interfaces or processes that enhance human efficiency, often using tools like usability testing and ergonomic standards.

Job description

Diamond Foundry Inc. is solving the thermal limitation at the foundation of today's most exciting tech industries -- AI & cloud compute, electric-car power electronics, and 5G/6G wireless. We have managed to produce the world's first single-crystal diamond wafers and are now on a mission to put a diamond behind every chip. We are the rare unicorn that has grown fast and profitably. We received $515m in funding and are executing a multi-$B expansion plan for one of the greenest forms of tech manufacturing: converting greenhouse gas into diamond wafers using zero-emission energy.

We're looking for a People & Culture Generalist to support a fast-paced, high-trust startup environment in a highly technical manufacturing company.

This role spans HR operations, employee relations (ER), HR compliance, HRIS management, and employee lifecycle support across both hourly manufacturing/technician teams and salaried engineering and corporate staff.

This is an opportunity to help build and scale People Operations infrastructure at a fast-growing organization where your ideas, judgment, and execution will directly influence employee experience and company culture.

You'll need strong judgment, discretion, and the ability to connect day-to-day HR work to broader business needs.

Responsibilities
  • Partner with managers and leadership to support employee experience, team effectiveness, and organizational growth
  • Own and improve core People Operations processes across the employee lifecycle, including onboarding, offboarding, and HR systems administration
  • Build and scale HR policies, workflows, and infrastructure with an ownership mindset and focus on continuous improvement
  • Manage employee relations matters with professionalism, sound judgment, and discretion
  • Ensure compliance with federal, state, and local employment laws and HR best practices
Requirements
  • 3-6 years of experience in HR Generalist, People Operations, or HRBP-adjacent roles
  • Strong knowledge of HR compliance, California labor law, and FLSA classification (hourly vs. salaried)
  • Experience handling employee relations (ER), investigations, and confidential matters
  • Experience supporting both hourly and salaried employee populations, ideally in manufacturing, engineering, or technical environments
  • Familiarity with HRIS systems (e.g., Rippling, BambooHR, Workday, Gusto, or similar) and comfort working in fast-paced, high-growth environments
$105,000 - $120,000 a year
 Actual compensation will be determined based on experience, expertise, and scope of responsibilities. Higher-level candidates will be considered, with adjusted salary as appropriate.
Diamond Foundry believes in supporting our employees from the workplace to their personal and home life. We provide eligible employees with an opportunity to enroll in a variety of benefit programs, generally including health insurance, flexible spending accounts, retirement savings plans, life and disability insurance programs, and a number of programs that provide for both paid and unpaid time away from work. Perks include employee discounts to VRAI. Our benefits begin as early as your first day of employment. Medical and vision coverage are retroactive to your start date, while dental and voluntary benefits take effect once you've completed your enrollment.

Diamond Foundry is an Equal Opportunity Employer and considers qualified applicants for employment without regard to race, color, creed, religion, national origin, sex, sexual orientation, gender identity and expression, age, disability, veteran status, or any other protected factor under federal, state or local law.

Diamond Foundry Inc. is committed to operating in full compliance with all applicable state and federal laws. Our commitment extends to ensuring that our manufacturing and engineering departments adhere to the highest standards of legal and regulatory compliance. Additionally, these departments may have specific physical requirements to ensure the safety and efficiency of our operations. We prioritize the well-being of our employees and strive to create a work environment that promotes both legal compliance and the optimal functioning of our manufacturing and engineering processes.

Manufacturing and Engineering Departments Physical Requirements:
-Use appropriate PPE and follow all safety policies, practices, and procedures.
-This position will often: Sit, stand for long periods, walk, grasp, reach with hands and arms, lift below and above shoulders, bend, twist at the waist,  climb, balance, stoop, squat,  kneel, crawl, talk, hear, see, use fine finger manipulation, and complete repetitive motions.

-Some tasks may require driving or the use of foot controls
-Lift/carry and push/pull up to 50 pound

This employer participates in E-Verify and will provide the federal government with your Form I-9 information to confirm that you are authorized to work in the U.S.
If E-Verify cannot confirm that you are authorized to work, this employer is required to give you written instructions and an opportunity to contact Department of Homeland Security (DHS) or Social Security Administration (SSA) so you can begin to resolve the issue before the employer can take any action against you, including terminating your employment.
Employers can only use E-Verify once you have accepted a job offer and completed the Form I-9.
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information.
