Concord isn't your typical consulting firm; we are an execution company with a passion for making things happen. Our mission is to help clients enhance customer experiences, optimize operations, and revolutionize their product offerings through seamless integration, optimization, and activation of technology and data.

We are purpose-built, merging the industry’s top specialty companies to amplify our Innovation Capabilities in analytics & AI, data management & engineering, UX and digital experience, and technical platform integration, automation & security engineering.

We are seeking a Senior Human Factors & Usability Engineer who combines deep expertise in medical device usability with an entrepreneurial, ownership-driven mindset. You will play a critical role in shaping the next generation of diagnostic medical devices—leading human factors strategy, anticipating user risks and needs, and driving solutions from concept through verification.

As a senior member of the team, you won’t just execute studies, you will own the usability engineering vision, identify what needs to happen before being asked, and translate complex insights into clear recommendations that influence product, engineering, and leadership teams.

This role is ideal for someone who thrives in ambiguity, moves quickly from insight to action, and takes full responsibility for outcomes.

• Own the usability engineering roadmap across the product lifecycle—from early discovery to market release.
• Anticipate user needs, risks, and system-level implications before issues arise.
• Define the vision, strategy, and priorities for human factors activities and communicate them across cross-functional teams.

• Lead the creation and maintenance of Usability Engineering Files in accordance with IEC 62366 and FDA Human Factors guidance.
• Identify user profiles, tasks, critical use scenarios, usability risks, and system requirements.
• Translate user needs, UX research insights, clinical workflows, and business needs into actionable HFE requirements.

• Independently plan, design, and execute formative and summative usability studies (hardware, software, or integrated systems).
• Manage external vendors and ensure high-quality execution, documentation, and data integrity.
• Analyze behavioral and physiological data to uncover deep insights that drive product decisions.

• Champion usability, safety, accessibility, and quality across R&D, Engineering, UX, Clinical, Regulatory, and Marketing.
• Facilitate workshops with customers, clinical partners, and internal teams to capture system-level insights and drive alignment.
• Proactively identify gaps, propose solutions, and push initiatives forward with minimal supervision.

• Serve as a subject matter expert for Human Factors Engineering within the organization.
• Mentor and guide junior team members on methodology, study design, analysis, and professional development.
• Present insights and recommendations persuasively to technical and non-technical audiences, including leadership.

• 5–8+ years of applied Human Factors Engineering experience in the medical device or healthcare technology industry.
• Demonstrated ability to own the HFE strategy on complex products, anticipating challenges, proposing solutions, and driving execution.
• Deep knowledge of IEC 62366, FDA HFE guidance, Design Controls, and risk management (ISO 14971).
• Proven experience planning, conducting, and documenting both formative and summative usability studies.
• Experience synthesizing behavioral, physiological, and qualitative data into actionable design recommendations.
• Familiarity with UX…
