WHAT'S IN IT FOR YOU

• Opportunity to work in a collaborative, high-impact team supporting critical enterprise infrastructure
• Long-term W2 contract with potential for renewal
• Competitive medical, dental, vision, HSA, and supplemental coverage options
• 401(k) plan with company match and full vesting after eligibility
• Paid time off, sick time, and company holidays (subject to eligibility)
• Employee Assistance Program (EAP) with virtual counseling, financial/legal services, life coaching, and more
