After adding 1,800 workers over the last year to ramp up production of F-35 fighter jets, Lockheed Martin said Monday it’s looking to hire 400 more technicians, mechanics and assemblers to help tackle the growing workload.

Lockheed will be interviewing candidates for those positions at a July 30 hiring event being hosted at the Sheraton Fort Worth, with qualified applicants getting a shot at on-the-spot job offers.

The Maryland-based defense company, which builds state-of-the-art F-35 jets at its Fort Worth plant, said it’s specifically looking to hire in several roles: avionics technician; milling machinist; low observable coater; structural assemblers; aircraft mechanics; field and service mechanics; and electrical assemblers.

It comes as Lockheed is increasing its rate of F-35 production, from 66 in 2017 to an expected 91 in 2018. The company will need to continue ramping up its operation to meet its eventual target of 160 aircraft per year by 2023.

So far, the company has delivered about 310 F-35s out of what’s expected to be a total order of more than 3,000 aircraft.

Lockheed employs about 15,200 people at its Fort Worth facility, the headquarters for its aeronautics division. The company held similar hiring events in Fort Worth last summer in an effort to hire 1,800 workers by the end of 2018, a goal it said Monday had been met.

The hiring event will run from 7 a.m. to 5 p.m. at the Sheraton Fort Worth, 1701 Commerce St. Pre-registration is closed due to capacity constraints, but there will be a section available for applicants who did not pre-register. The company asks that candidates bring a copy of their resume.
