• Technical Problem-Solving: Help resolve the most complex technical issues affecting operations. 
• Collaboration: Work alongside our Full-Stack .NET Developer and across departments, sharing knowledge and adapting to feedback. 
• Professionalism: Communicate well, stay calm under pressure, and show emotional intelligence in team settings. 
• Staying Flexible: Other opportunities that may arise to use your skills and gifts as assigned. 

What We Have to Offer (Perks):

• Supportive Team Environment: Join a team that celebrates achievements together and values not just what you do - but who you are. 
• Culture Focused on People: We prioritize work-life balance, emotional intelligence, and mutual respect in everything we do.
• Genuine Feeling of Care: You aren’t just a number here. We like to work hard, have fun, and recognize that supporting employee wellbeing is both our ethical duty and makes for incredible business outcomes. 
• Competitive salary, the option to elect benefits (medical, dental, and vision) that start the first day of the next month, paid time off, paid volunteer time (to an organization of your choice), free gym membership, and the ability to contribute to a 401k with a generous match.
