Meet JT Hayes

Federal Services, Lead Account Manager

Tell us about what you do for SOC. 

I work in a group called Federal Services. We’re a staffing organization, traditional staffing in the sense that clients need contractors, they need support. Our focus is cleared staffing, anything from Department of Defense, to Department of Energy, to Public Trust, anything like that. As account manager, I manage the relationship between my clients and SOC, and we have crews on the team that support and fill the positions. My job is to just make sure that everything goes smoothly, the client’s happy, find new business – all of it.

What do you like most about being an Account Manager?

I like the excitement of opening the doors to a new client, delivering for the client, developing a partnership geared towards future growth for the client and SOC, and providing the Federal Services recruiters with awesome clients and jobs to recruit on.

What is the culture like in the area that you support?

Account Managers are driven, organized, focused, and very competitive. We all want to be as successful as possible, but we also want our team members to succeed. We all must do very well individually or we all will struggle as a team to get Federal Services to our desired goals. We have lots of fun and camaraderie on our team.

Meet Kim Lowry

Federal Services Recruiting

What do you like most about being a recruiter?

I love that with every new job we get to fill comes a new and different challenge. You are never doing the same thing from one day to the next.

What are you looking for in a candidate?  

We are mainly focused on candidates with clearances.  I am looking for people who are interested in a job change, whether it be now or in the future.

What is the culture like in the area that you recruit in?

It is very fast paced and competitive, because the candidate pool is much smaller with the clearance requirements.

Government Services Recruiting

What do you like most about being a recruiter?

What I love most about being a recruiter is getting to talk to different types of people every day. It’s never a dull moment talking to candidates and getting to know them. It’s a great feeling when one of my candidates get a position they’ve been vying for. The gratitude I feel to be able to help another person get a new role—to start a new chapter—is endless. It’s amazing being able to have such an impact on another person’s life and livelihood.

What are you looking for in a candidate?

I support recruiting in many different areas of the Government Services Division. This includes candidates with experience in Architecture & Engineering, CONUS Physical Security, Cyber Security, as well as various Operations and Craft roles.

What is the culture like in the area that you recruit in?

Across all of the areas I recruit in, the culture is very open and friendly. We are veteran friendly across the board and lucky enough to have so many mission-driven employees!

Meet Thomas 'TK" Kane

SOC Canine Recruiting

What do you like most about being a recruiter? 

I love working with Canine Handlers and helping protect United States interests around the world. In my work, I have an opportunity to change a dog handler’s life by showing them different available career options. Knowing that I've helped change someone’s life for the better is an amazing feeling, and the satisfaction I get from this doesn’t get much better.

What are you looking for in a candidate?  

First, a candidate needs to meet the basic requirements of having at least two years of military or law enforcement canine experience. Then, I look for candidates who are confident in what they know about working with their dogs while still having the humility to be able to learn from other handlers and trainers.   

What is the culture like in the area that you recruit in? 

We have two types of employees ­ the two ones and the four legged ones. The trainers take the time to get each canine team ready for their deployments. We take this seriously, because we know the importance of exceeding our clients’ needs and protecting American interests abroad. SOC Canine Solutions team is not just a group of co-workers but friends for a lifetime.
