Job description

Assured Space Access Technologies, Inc. is a defense and engineering firm delivering phased array, radar, RF payload, and secure 5G communications solutions to government and prime contractor customers. This position supports the 5G Product Team and related product and service lines based at our Irvine, California facility.

Team: 5G Product Team, Engineering Support

Reports To: Engineering Support Manager

Location: Irvine, CA (on-site)

Employment Type: Full-Time

Base Salary Range: $115,000 – $155,000

Clearance: This position requires the ability to obtain and maintain a U.S. Secret clearance, which requires U.S. citizenship. An active clearance is preferred.

Position Summary

Assured Space builds equipment that people have to install, configure, operate, and troubleshoot, often in the field, often under time pressure, and sometimes by operators who did not design it. Our 5G infrastructure products, radar systems, and RF payloads all have human touchpoints.

This role owns them. You will apply human factors engineering to our product designs: operator and maintainer interfaces, physical accessibility and serviceability, control and display design, labeling, error prevention, and documentation usability. You will run evaluations with real users and translate what you observe into design requirements engineering can build to.

You will work across hardware, firmware, and software teams as the advocate for the person on the other end of the product.

Key Responsibilities

• Develop human factors requirements for products and translate them into design criteria engineering teams can implement and verify.

• Apply human engineering design criteria, including MIL-STD-1472 where contractually invoked, to operator and maintainer interfaces, controls, displays, labeling, and physical layout.

• Conduct task analysis, workload assessment, and use-error analysis for installation, operation, maintenance, and troubleshooting scenarios.

• Plan and run usability evaluations and human-in-the-loop assessments using mockups, prototypes, and production hardware, and report findings with actionable design recommendations.

• Assess physical accessibility, serviceability, anthropometric fit, reach and clearance, lifting and handling, and field-maintainability of hardware designs.

• Review and improve operator interface software and configuration workflows in partnership with software and firmware teams.

• Contribute human factors input to technical manuals, installation instructions, quick-reference materials, and training content.

• Evaluate environmental and use-context factors, including lighting, noise, protective equipment, and field conditions, against design assumptions.

• Support design reviews as the human factors reviewer, and maintain human factors verification evidence for programs where it is a contractual requirement.

• Partner with mechanical, electrical, firmware, and technical publication teams throughout the design cycle, not just at the end.

Required Qualifications

• Bachelor’s degree in human factors engineering, industrial engineering, systems engineering, cognitive psychology, or a closely related field.

• 4+ years of applied human factors, usability engineering, or human-systems integration experience on physical products or complex systems.

• Demonstrated experience planning and conducting usability evaluations and translating findings into design changes that shipped.

• Working knowledge of task analysis, use-error analysis, and human performance assessment methods.

• Ability to work embedded in an engineering team and influence design decisions without owning the design.

• Strong written communication, since much of the output is requirements and findings other people act on.

• Ability to obtain and maintain a U.S. Secret clearance, which requires U.S. citizenship.

• Ability to work on site in Irvine, CA.

Preferred Qualifications

• M.S. in human factors, human-systems integration, or a related discipline.

• Direct experience applying MIL-STD-1472 and DoD human systems integration practice on a defense program.

• Experience with field-deployed, ruggedized, or tactical equipment used under operational conditions.

• Experience with operator interface and configuration software design, including network or communications management interfaces.

• Familiarity with technical publication development and maintainability analysis.

• BCPE certification or comparable professional credential.

What We Offer

• Comprehensive healthcare benefits, including medical, dental, and vision coverage.

• 401(k) with company matching.

• Paid time off and company-observed holidays.

• Professional development support, including certification and training relevant to your specialty.

• Company-sponsored security clearance processing.

• Relocation support may be available depending on the role and candidate.

• High-impact work in an aerospace and defense engineering environment, with direct visibility to company leadership.
