“Our Culture”:  

At Capnexus, the central principles that we all adhere to, and the glue that holds us together, are our keystones. Our four keystones are:  

"A Customer Obsessed, Delivery Focused, Culture"

• We’re driven to exceed our customers’ expectations by listening, leading, solving problems, and delivering what we promise  

• We aim to be the most dependable and trusted partner serving our customers. TRUST = CONSISTENCY x TIME  

"A Culture of Learning and Sharing"

• We value “Lifetime Learners”; those who are hungry, competitive, curious, and self-motivated in their pursuit of knowledge.  

• Personal and professional growth depends on teamwork and continuous learning. By sharing knowledge, skills, ideas, and effort, we benefit our customers, ourselves, and our communities.  

• We recognize that the thoughts, feelings, and backgrounds of others are as important as our own. Everyone has something to learn and everyone has something they can teach.  

• Knowledge and ability are valued. Sharing knowledge and helping others learn new capabilities is valued exponentially.

"A Culture of Growth and Scalability"   

• Growth comes from not establishing barriers in your role. “Cross functional skill sets are valued and help us deliver to our customers in a truly agile fashion. It comes with understanding that when asked to do something new, you will need support, have questions, and make some mistakes along the way.  

• The most elegant solution is a simple solution. Simple doesn’t mean easy. It’s often more difficult to break a complex problem down into simple, scalable terms. We don’t appreciate, or value, over architected solutions or superfluous coding.  

• Time is one of our most precious commodities.  Scalability implies being respectful of this and passionate about making the most efficient use of each and every one of our team members time.  

"All Work is Strategic" 

• No matter how small a project or assignment appears, every single engagement is an opportunity for us to prove ourselves, build trust, and develop relationships that last and grow  

• Every task, interaction, and commitment matters  

• Big or small, we execute our plans and strategies with focus, commitment, and passion  

We offer:  

Job Type: Full-time
