About the Workforce Development Team
The Workforce Development team is dedicated to cultivating the next generation of manufacturing talent within a challenging, equitable, and meritocratic environment.
Our goal is to accelerate the maturity and operational effectiveness of Hadrian's factories through targeted training programs.
The team is responsible for developing and managing a comprehensive training system, driving software adoption, standardizing operational processes, and maintaining an integrated training and certification ecosystem.
The Role
As aTraining Specialist, you will be the operational owner of training performance across a defined set of stations in our manufacturing environment. You will be responsible for translating new and updated processes into effective, on-the-job learning experiences that result in consistent execution and measurable technician proficiency. Your focus will be on velocity, quality, and team self-sufficiency.
You will be the first to master new procedures, working closely with technicians and trainer cohorts to ensure flawless adoption of every process. You will monitor and act on training velocity (time to full crew readiness) and training quality (adherence to standards), closing gaps proactively. Your north star: Every station in your scope runs to standard, every shift, with a self-sufficient team.
What You'll Do

• Lead all training activities for your assigned area, delivering on-the-job instruction and acting as the technical expert.
• Work directly with technicians to understand process nuances, pain points, and improvement opportunities.
• Master every process in your area and convert new methods into clear, teachable steps.
• Train technicians and technician-trainers to ensure consistent, standard execution across all shifts.
• Adapt coaching approaches to individual learning styles and support trainees through challenges.
• Mentor technician-trainers to promote best practices in training delivery.
• Own the full evaluation process, including quizzes, assessments, and progress reporting.
• Create and refine evaluation criteria covering both hard and soft skills.
• Partner with process designers to define tasks and decision points using structured "if/then" logic.
• Maintain up-to-date, version-controlled training content that is always audit-ready.
• Ensure returning technicians are aligned with the latest training standards.
• Conduct and support training audits to ensure 100% procedural compliance.
• Manage a blend of on-the-job and off-the-job training formats.
• Collaborate with Learning System Engineers to develop and execute continuous improvement roadmaps.

What We're Looking For

• 1+ years of experience in a training, instructing, or teaching role with a focus on entry-level individual contributors
• At least 2 years of experience working in a production / inspection environment
• Proven ability to train people with experience ranging from entry level - mid level
• Aptitude for rapid learning, reteaching, and influencing process adoption
• Ability to independently recognize human patterns (both macro + micro) and provide actionable, objective, and mature recommendations to leadership

What Will Set You Apart

• Passionate about training, employee career development, and the Hadrian mission of reindustrializing the nation's workforce
• Training, instructing, or teaching experience in an operational environment
• The ability to influence others without direct authority - you will not be a people manager, but your success is directly tied to influencing ability
• High emotional IQ - able to self-improve after receiving feedback, provide guidance to trainers, and continuously learn and grow through the role

Compensation
For this role, the target salary range is $24/hr - $40/hr(actual range may vary based on experience).
This is the lowest to highest salary we reasonably and in good faith believe we would pay for this role at the time of this posting. We may ultimately pay more or less than the posted range, and the range may be modified in the future. An employee's pay position within the salary range will be based on several factors, including, but not limited to, relevant education, qualifications, certifications, experience, skills, geographic location, performance, and business or organizational needs.
