Why Work Here?
You will join a company that invests in its people through comprehensive benefits and meaningful time off. Employees have access to medical, dental, vision, and life insurance, as well as a 401(k) plan with a competitive matching contribution after a short eligibility period. Generous paid vacation starts at 10 days and grows each year up to a substantial balance, complemented by paid time off, floating days, and multiple paid holidays. The organization values work-life balance by offering structured shifts and clear overtime expectations, and it fosters a supportive culture where employees can build long-term careers with strong benefits and a stable schedule.
Work Environment
This is a hands-on industrial role in a manufacturing facility with both first and second shift opportunities. First shift typically runs from 5:00 a.m. to 3:30 p.m. with a 30-minute lunch. Standard shifts are 8 hours, with the possibility of extending to 10 hours as needed. There may be occasional Saturday work up to 8 hours, and some days may require a 6:00 a.m. start, so schedule flexibility is important. The facility is well lit and located in a character-filled building with many windows, originally constructed in 1906. Temperatures can vary with the seasons and may range from warm in the summer to cooler in the winter; in hotter months, fans and open doors help improve airflow, and cold drinks and frozen treats are provided. You will regularly use hand and power tools, work around machinery and mechanical equipment, and operate in a production environment that emphasizes safety, quality, and teamwork. Dress is typical for an industrial manufacturing setting, suitable for working with tools, machinery, and materials in a shop floor environment.
