Reaction Operator information

What is the difference between Reaction Operator vs Chemical Plant Operator?

AspectReaction OperatorChemical Plant Operator
CredentialsHigh school diploma, safety training, sometimes certificationsHigh school diploma, safety training, certifications often preferred
Work EnvironmentProcessing units, chemical reactors, controlled environmentsProcessing plants, chemical manufacturing facilities
Industry UsageSpecific to chemical reactions and processesBroader chemical manufacturing and processing
Job FocusMonitoring and controlling chemical reactionsOverseeing entire production processes

Reaction Operators focus on managing chemical reactions within reactors, ensuring safety and efficiency. Chemical Plant Operators oversee overall plant operations, including multiple processes. While both roles require safety training and similar certifications, Reaction Operators specialize in reaction control, whereas Chemical Plant Operators handle broader plant functions.

What education is needed to be a reaction operator?

Reaction operators typically need a high school diploma or equivalent; some positions may require post-secondary education or technical training in chemistry, process technology, or related fields. Relevant skills include understanding chemical processes and operating control systems, and certifications such as OSHA safety training can be beneficial.

Job description

Job Summary
General Atomics Aeronautical Systems, Inc. (GA-ASI), an affiliate of General Atomics, is a world leader in proven, reliable remotely piloted aircraft and tactical reconnaissance radars, as well as advanced high-resolution surveillance systems.
With consultative direction, this position exercises considerable latitude in determining technical objectives for the review, research, design, development, and implementation of advanced payload systems. The successful candidate will serve as a project lead and subject matter expert (SME) within the Payload Design and Analysis group, working across a variety of quick-reaction and new-start payload projects.
This role focuses on the end-to-end lifecycle of payloads for airborne, ground mobile, maritime, and fixed installations, including conceptual design, detailed design, analysis, integration, test, and transition to production. The candidate will be expected to apply strong engineering fundamentals and sound engineering judgment, demonstrate strong interdisciplinary skills, and effectively "productionize" designs for repeatable, reliable manufacture and fielding.
Functioning in an advisory and leadership capacity, this position participates in the planning and oversight of payload development efforts and provides direction and guidance to professional and support staff. This position formulates multi-year technical plans for payload solution development, documentation, and deployment, and is responsible for meeting applicable compliance, reporting, and safety standards.
This position evaluates the integration of payload solutions within the overall aircraft and mission system architecture, including support to aircraft conceptual design activities. Responsibilities include planning and overseeing documentation, analysis, testing, maintenance, and engineering updates. The candidate communicates with engineering professionals, payload users, and management throughout the development cycle; represents the company as a prime technical contact on assigned payload systems and projects; and interacts with senior internal and external personnel on technical matters requiring coordination between organizations. The candidate anticipates future payload needs and contributes to the development of new or expanded business opportunities.
DUTIES AND RESPONSIBILITIES:
  • Determines annual and multi-year technical objectives for designated payload systems and related project(s)/program(s) within the Payload Design and Analysis group.
  • Serves as a prime technical expert and project lead for new and quick-reaction payload development efforts.
  • Acts as an expert consultant and advisor in payload design and analysis, including structural, thermal, electrical, and integration considerations across airborne, ground mobile, maritime, and fixed environments.
  • Provides technical leadership and direction to multi-disciplinary teams, ensuring strong cross-functional collaboration (e.g., structures, systems, electrical, manufacturing, test, and operations).
  • Applies strong engineering fundamentals and sound engineering instincts to resolve unusually complex technical problems and to make timely decisions in a fast-paced, quick-reaction project environment.
  • Leads the "productionization" of payload designs, including design for manufacturability, reliability, maintainability, and cost, and coordinates with manufacturing and supply chain to transition designs into production.
  • Supports and influences aircraft conceptual design by defining payload concepts, interfaces, performance requirements, and integration constraints, and by assessing payload impacts on aircraft configuration and mission capabilities.
  • Directs and allocates technical resources and professional staff to achieve project objectives, including planning, organizing, scheduling, and coordinating workloads to meet established deadlines and milestones.
  • Develops new and/or expands existing business opportunities by identifying innovative payload concepts, architectures, and technology insertions that address customer needs.
  • Ensures compliance with applicable engineering standards, regulatory requirements, reporting obligations, and safety.
  • Participates in the planning, selection, retention, and development of professional staff within the Payload Design and Analysis group.
  • Publishes and presents technical papers and abstracts, and participates in internal and external technical program reviews as a recognized technical authority.
  • Maintains the strict confidentiality of sensitive information.
  • Performs other duties as assigned.
  • Responsible for observing all laws, regulations, and other applicable obligations wherever and whenever business is conducted on behalf of the Company.
  • Expected to work in a safe manner in accordance with established operating procedures and practices.

We recognize and appreciate the value and contributions of individuals with diverse backgrounds and experiences and welcome all qualified individuals to apply.
Job Qualifications
  • Typically requires a bachelors degree, masters degree or PhD in engineering or a related technical discipline from an accredited institution and progressive engineering experience as follows; fifteen or more years of experience with a bachelors degree, thirteen or more years of experience with a masters degree, or ten or more years with a PhD. May substitute equivalent engineering experience in lieu of education.
  • Demonstrates a detailed and extensive technical expertise and application of engineering principles, concepts, theory, and practice as well as project and/or program leadership including organizing, planning, scheduling, and coordinating workloads to meet established project deadlines or milestones.
  • Strong interdisciplinary background with the ability to work effectively across mechanical, electrical, systems, software, and manufacturing engineering domains.
  • Proven experience leading hardware development from concept through detailed design, integration, test, and transition into production, including design for manufacturability and reliability.
  • Demonstrated ability to thrive in a quick-reaction, fast-paced project environment, including managing technical risk, making timely trade decisions, and delivering solutions on aggressive schedules.
  • Ability to contribute to the development of new concepts and principles and to resolve unusually complex technical problems.
  • Ability to serve as spokesperson on projects and/or programs and to act as a technical expert in payload design and analysis and related engineering areas.
  • Strong communication, presentation, and interpersonal skills enabling effective leadership and interface with other departments, all levels of management, professional and support staff, customers, potential customers, and government representatives.
  • Customer-focused mindset with the ability to formulate plans based on innovative payload designs that resolve advanced technical engineering problems and meet mission needs.
  • Ability to work on a self-initiated basis and in a team environment, and to work extended hours as required.
