Scientist/Engineer/Emergency Response Planner
with a focus in Cybersecurity

Horsley Witten Group is expanding the services we currently provide into the fast-growing field of cybersecurity as it relates to drinking water and wastewater utilities. This position reflects changing times and emerging issues and, as such, HW is approaching this employee search with some flexibility. For the first several years of employment, the successful candidate will focus primarily on cybersecurity services, helping us to meet upcoming contract assignments. These assignments will regularly include:

  • Assessments of current cybersecurity practices used by utilities to determine if they are capable of preventing and/or responding to a cyber-attack
  • Development of cybersecurity training materials for utilities and state and federal officials involved in regulatory oversight of drinking water and wastewater utilities
  • Leadership of virtual and in-person training sessions for utility managers and operators
  • Oversight of work products and project deliverables

In addition, the candidate will have an opportunity to work with other staff to develop both in-person and virtual training events that aid both governmental and private clients in preparing for, mitigating against, responding to, and recovering from both natural and man-made disasters.  HW has developed a reputation as a leader in developing events that promote preparedness and coordination of the drinking water and wastewater sector with jurisdictional response partners (e.g., police, fire, emergency management, public health). 

As with almost all our employees, we expect the successful candidate will grow professionally to assist with other water resource projects (science and/or engineering) and perform in a collaborative, multi-disciplinary setting. Overnight travel is not required initially, but it may be as more trainings are conducted in-person post-COVID.

Our preference for this position is an emergency response planner, water resource scientist/engineer, or water/wastewater utility operator/manager who can help with our cybersecurity assessments and trainings for drinking water and wastewater utilities across the U.S.A.  A bachelors or master’s degree in emergency planning, environmental science or engineering with five years of experience is preferred. For these candidates, experience with cybersecurity topics and/or a cybersecurity certificate is a plus.

As described above, in accordance with our flexible approach, HW also would consider candidates who have dedicated much of their studies and career to cybersecurity, but also demonstrate an ability to apply these skills to the drinking water and wastewater sector.
