Not just another staffing company

Based in Denver, Colorado, Unison Systems is an award-winning provider of IT and Engineering staffing services to Fortune 1000 customers across the United States.  We provide resourcing solutions including contract consulting, contract-to-hire, direct placement staffing, and end-to-end project management solutions, with a laser focus on resource fit and customer satisfaction.

Diverse Industry Experience.

Unison Systems’ clients come from a diverse array of industries: Broadband/Media, Maritime/Defense, Technology, Telecom/Mobile, Financial Services, Energy, Oil & Gas, Healthcare/Life Sciences, Mining, and more. Across these industries, companies share two common drivers:

FIRST: They have an ever-increasing need/use for technology and engineering resources, and

SECOND: They covet the most talented and experienced people to deliver their project initiatives to successful deployment. Unison Systems proudly employs and delivers multidisciplinary experts with the technical and business skills to drive our clients’ initiatives to success.

How do we do differentiate ourselves?

Unison Systems believes in experienced people. Experienced recruiters and account managers delivering experienced talent to our clients. Experienced talent delivering superior services and solutions. You will find experience across our organization, and it has resulted in a noticeable distinction: 75% of our current consulting staff are Unison veterans (they’ve worked with us before), and several of our largest customers today were among our very first, over 20 years ago. This kind of loyalty and longevity doesn’t happen by accident. In a crowded industry, Unison distinguishes itself with experienced, proven people across our organization.


Over the years Unison Systems has been honored numerous times for achievements in revenue attainment, growth percentage, job creation, and industry ranking. We believe our consistent performance is directly attributable to our core focus on client satisfaction above all else, a superb staff, and a positive and healthy culture that attracts and retains top talent.
