What is a factory line worker?

Factory line workers are employees who work on assembly lines in manufacturing plants. Their primary responsibility is to assemble, package, or inspect products as they move through various stages of production. They often perform repetitive tasks, operate machinery, and ensure quality control to help maintain the efficiency and safety of the production process. Factory line workers typically work as part of a team and must follow strict safety protocols and production guidelines.

What is the difference between Factory Line Worker vs Assembly Line Worker?

AspectFactory Line WorkerAssembly Line Worker
CredentialsHigh school diploma or equivalentHigh school diploma or equivalent
Work EnvironmentFactories, production plantsFactories, production plants
Industry UsageManufacturing, productionManufacturing, production
Job FocusOperating machinery, quality checksAssembling products, component fitting

Both Factory Line Workers and Assembly Line Workers typically work in manufacturing environments with similar credentials. The main difference lies in their focus: Factory Line Workers may operate machinery and perform quality checks, while Assembly Line Workers primarily assemble products or components. Understanding these distinctions can help job seekers find roles that match their skills and interests within the manufacturing industry.

What are some common challenges faced by factory line workers, and how can they be managed effectively?

Factory line workers often encounter challenges such as repetitive tasks, maintaining focus during long shifts, and adapting to fast-paced environments. To manage these effectively, workers can take regular short breaks to reduce fatigue, follow ergonomic guidelines to minimize strain, and communicate with supervisors about workflow adjustments. Teamwork and clear communication with colleagues also play a crucial role in ensuring safety and efficiency on the line.

Job description

Hadrian - Manufacturing the Future
Hadrian is building autonomous factories that help aerospace and defense companies manufacture rockets, satellites, jets, and ships up to 10x faster and up to 2x cheaper. By combining advanced software, robotics, and full-stack manufacturing, we are reinventing how America produces its most critical parts.
We're accelerating our mission with the launch of Factory 3 in Mesa, Arizona, a 290,000-square-foot facility creating 350 new jobs. We are expanding rapidly to support thousands of future hires, launching Hadrian Maritime to expand into naval production, and introducing a Factory-as-a-Service model that delivers complete systems instead of individual parts.
Hadrian is backed by leading investors including T. Rowe Price, Lux Capital, Founders Fund, and Andreessen Horowitz, our fast-growing team is united around reindustrializing American manufacturing for the 21st century and beyond.
The Role:
We are seeking a Simulation Engineer, Omniverse Specialist to design, develop, and maintain high-fidelity simulation artifacts, digital twins, and process visualizations that support advanced manufacturing decisions across the company. This role will partner closely with manufacturing, automation, special projects, and product teams to deliver decision-grade simulations that accelerate factory design, de-risk capital investments, and improve production outcomes.
What You'll Do:
  • Develop, maintain, and evolve high-fidelity 3D and discrete-event simulations using NVIDIA Omniverse and related toolchains.
  • Create reusable simulation assets, plugins, workflows, and visualization pipelines for cross-factory use.
  • Translate ambiguous operational inputs (verbal descriptions, low-fidelity drawings, early layouts) into accurate, runnable simulation models.
  • Partner with cross-functional stakeholders (Operations, Automation, Controls, Finance, Special Projects) to define simulation requirements and success metrics.
  • Deliver simulation insights that inform layout decisions, throughput targets, capital planning, and risk mitigation.
  • Steward the simulation toolchain, ensuring scalability, maintainability, and alignment with long-term platform architecture.
  • Rapidly prototype models (0โ†’1) and iterate them into production-ready, decision-grade assets.
  • Communicate findings clearly to both technical and non-technical audiences, including executives.
  • Support onboarding and knowledge transfer by documenting workflows, assumptions, and modeling standards.

What We're Looking For:
  • Bachelor's degree in Computer Science, Software Engineering, Mechatronics, Industrial Engineering, or a related field (or equivalent practical experience).
  • 2-4 years of hands-on experience with Omniverse and/or robotics or factory simulation environments.
  • 2+ years of engineering experience in a factory, manufacturing, or industrial setting.
  • Demonstrated ability to make data-driven recommendations that improve production or operational metrics.
  • Experience modeling multiple process technologies and production flows based on incomplete or low-fidelity inputs.
  • Proficiency in Python (OOP) and/or C++, with experience using simulation or visualization APIs.
  • Experience working with CAD data and industrial layouts.

What Will Set You Apart:
  • Experience with Visual Components, discrete-event simulation engines, or similar platforms.
  • Familiarity with Unity, Unreal Engine, Blender, AnyLogic, or Siemens Tecnomatix.
  • Strong industrial engineering fundamentals (line balancing, takt/cycle time modeling, throughput analysis).
  • Experience cleaning, parameterizing, and automating CAD assets for simulation reuse.
  • Background in digital twin platforms or large-scale manufacturing simulations.

Compensation:
For this role, the target salary range is 150k-200k (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.
Benefits for Full-time Employees
  • Medical, dental, vision, and life insurance plans for employees
  • 401k
  • Relocation support may be provided for certain situations, based on business need.
  • Flexible vacation policy
  • Equity
