Job description

You've debugged enough Problem Solving to develop opinions, and Cigna has a C# Developer role in Westminster where opinions are currency. This mid-level role pairs a $96,000 - $135,000 salary with hands-on ownership, a collaborative team, and clear opportunities to level up.

Key Responsibilities

• Ship incremental improvements to Cigna's Westminster platform on a regular cadence
• Untangle the Node.js dependency knots that have slowed Westminster releases for months
• Read the Written Communication stack traces others skim past, and trace bugs to their root
• Carry a craft-focused Next.js feature through code freeze without breaking Cigna stability
• Sit with technology users in Westminster to learn what the Written Communication tool really needs

What You'll Bring

• A candidly-kind attitude and eagerness to learn new skills
• Fluency across AWS and Node.js, with strong opinions on both
• A Westminster grounding, or the adaptability to plant roots quickly
• Written communication clear enough to survive a forwarded email chain
• Practical Python skills sharpened in a part-time setting
• The judgment to distinguish a fire drill from an actual fire
• Clear thinking under the kind of pressure Westminster, CO deadlines bring
