Sketches plans for developing jigs, fixtures, instruments, and related nonstandard apparatus. Modifies performance and operation of component parts and circuitry to specifications, using test equipment and precision instruments. Plans sequence of testing and calibration program for instruments and equipment according to blueprints, schematics, technical manuals, and other specifications. Performs preventative and corrective maintenance of test apparatus and peripheral equipment. Confers with engineers, supervisor, and other technical workers to assist with equipment installation, maintenance, and repair techniques. Analyzes and converts test data, using mathematical formulas, and reports results and proposed modifications. Sets up test equipment and conducts tests on performance and reliability of mechanical, structural, or electromechanical equipment. Selects sensing, telemetering, and recording instrumentation and circuitry. Disassembles and reassembles instruments and equipment, using hand tools, and inspects instruments and equipment for defects.

Design -- Knowledge of design techniques, tools, and principles involved in production of precision technical plans, blueprints, drawings, and models. Mathematics -- Knowledge of arithmetic, algebra, geometry, calculus, statistics, and their applications. Mechanical -- Knowledge of machines and tools, including their designs, uses, repair, and maintenance. Engineering and Technology -- Knowledge of the practical application of engineering science and technology. This includes applying principles, techniques, procedures, and equipment to the design and production of various goods and services. Computers and Electronics -- Knowledge of circuit boards, processors, chips, electronic equipment, and computer hardware and software, including applications and programming.

Equipment Selection -- Determining the kind of tools and equipment needed to do a job. Equipment Maintenance -- Performing routine maintenance on equipment and determining when and what kind of maintenance is needed. Mathematics -- Using mathematics to solve problems. Quality Control Analysis -- Conducting tests and inspections of products, services, or processes to evaluate quality or performance. Technology Design -- Generating or adapting equipment and technology to serve user needs. Active Learning -- Understanding the implications of new information for both current and future problem-solving and decision-making. Speaking -- Talking to others to convey information effectively. Reading Comprehension -- Understanding written sentences and paragraphs in work related documents.

Mathematical Reasoning -- The ability to choose the right mathematical methods or formulas to solve a problem. Information Ordering -- The ability to arrange things or actions in a certain order or pattern according to a specific rule or set of rules (e.g., patterns of numbers, letters, words, pictures, mathematical operations). Deductive Reasoning -- The ability to apply general rules to specific problems to produce answers that make sense. Problem Sensitivity -- The ability to tell when something is wrong or is likely to go wrong. It does not involve solving the problem, only recognizing there is a problem. Written Comprehension -- The ability to read and understand information and ideas presented in writing. Inductive Reasoning -- The ability to combine pieces of information to form general rules or conclusions (includes finding a relationship among seemingly unrelated events). Oral Expression -- The ability to communicate information and ideas in speaking so others will understand. Control Precision -- The ability to quickly and repeatedly adjust the controls of a machine or a vehicle to exact positions. Number Facility -- The ability to add, subtract, multiply, or divide quickly and correctly. Written Expression -- The ability to communicate information and ideas in writing so others will understand

Getting Information -- Observing, receiving, and otherwise obtaining information from all relevant sources. Repairing and Maintaining Mechanical Equipment -- Servicing, repairing, adjusting, and testing machines, devices, moving parts, and equipment that operate primarily on the basis of mechanical (not electronic) principles. Analyzing Data or Information -- Identifying the underlying principles, reasons, or facts of information by breaking down information or data into separate parts. Inspecting Equipment, Structures, or Material -- Inspecting equipment, structures, or materials to identify the cause of errors or other problems or defects. Monitor Processes, Materials, or Surroundings -- Monitoring and reviewing information from materials, events, or the environment, to detect or assess problems. Communicating with Supervisors, Peers, or Subordinates -- Providing information to supervisors, co-workers, and subordinates by telephone, in written form, e-mail, or in person. Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles). Identifying Objects, Actions, and Events -- Identifying information by categorizing, estimating, recognizing differences or similarities, and detecting changes in circumstances or events. Updating and Using Relevant Knowledge -- Keeping up-to-date technically and applying new knowledge to your job. Processing Information -- Compiling, coding, categorizing, calculating, tabulating, auditing, or verifying information or data.
