The Field Service Technician II is a developing field technician responsible for independently performing standard electrical testing, maintenance, and commissioning activities on high-voltage substations and power systems. Operating with limited supervision, the FST II manages assigned test procedures, produces detailed technical reports, and begins leading smaller-scope field assignments. The position will be based in our Abilene, TX office and will report to Dashiell’s Field Supervisor.

Employee may be called upon to perform any or all of the following functions:

• Independently perform standard electrical testing and commissioning activities on high-voltage substations, switch gear, transformers, circuit breakers, and protective relay systems with limited supervision.

• Execute a full range of standard test procedures including insulation resistance testing, contact resistance testing, turns ratio testing, power factor testing, hi-pot testing, and circuit breaker timing tests.

• Perform protective relay testing and calibration on microprocessor-based relay systems (e.g., SEL, ABB, Siemens, GE) using industry‑standard test equipment.

• Perform testing and commissioning of power apparatus including power transformers, current transformers, potential transformers, medium- and high‑voltage circuit breakers, and switch gear assemblies.

• Independently perform testing and maintenance of low‑voltage AC/DC systems including station batteries, battery chargers, inverters, DC distribution panels, and AC distribution systems.

• Perform electrical calculations including transformer turns ratios, power factor corrections, and relay/metering circuit verification.

• Interpret electrical drawings, schematics, one‑line diagrams, and wiring diagrams; redline drawings to reflect field conditions as needed.

• Understand and apply switching concepts and procedures for high‑voltage equipment.

• Prepare detailed test reports and commissioning documentation with accuracy and completeness; submit reports with minimal revision required.

• Lead smaller‑scope field assignments and task‑level work activities, coordinating with field crew members as needed.

• Provide guidance and mentorship to junior field staff on testing procedures, safety practices, and documentation standards.

• Communicate project status, technical findings, and any issues to the Field Supervisor and project leadership.

• Participate in and contribute to Job Safety Task Analyses (JSTAs), safety briefings, and incident reporting.

• Maintain, calibrate, and manage assigned company test equipment and tools.

• Perform special projects and complete other duties as assigned or requested.

• Deliver reliable, high‑quality testing and commissioning results that keep projects on schedule and meet client expectations.

• Strengthen project documentation standards by producing thorough, accurate test reports that require minimal revision.

• Contribute to workforce development by mentoring junior field staff and modeling professional field practices.

• Support project safety performance through active participation in safety planning and consistent adherence to safety protocols.

• Enhance project execution efficiency by independently managing assigned test procedures and reducing the need for supervisory…
