Description

Human Resources Generalist (Part-Time)

At Central Engineering Services, we believe that to reach our goals—individually and as a company—we must help our employees and clients reach theirs. We are a collaborative, humble, and growth-focused team where knowledge is shared, opinions matter, and employees are empowered to take ownership of their work. Our leadership is grounded in trust, accountability, and continuous improvement, and we value team members who contribute positively to that culture.

The Role

We’re seeking an experienced HR Generalist to support our Geotechnical, Environmental, and AEC teams. This is a hands-on role touching all aspects of HR. Our previous HR partner set a high bar—we’re looking for someone who brings strong judgment, professionalism, and a people-first approach.

• Layoffs & Unemployment: Managing reductions in force with compassion and professionalism, including unemployment claims, Oregon Employment Department responses, and severance coordination.
• Compliance & Administration: Maintaining employee files, updating the employee handbook, managing leave; including OFLA and PLO, workers' compensation, and staying current on Oregon and multi-state HR law.
• Benefits Administration: Supporting employees through benefits questions, open enrollment, and day-to-day HR needs.

Skills:

• Strong attention to detail and clear written communication
• Ability to manage multiple priorities and meet deadlines
• Collaborative, approachable, and effective communicator
