Job description

This mid-level C# Developer opening is for someone who treats Problem Solving documentation as a first draft they intend to improve. A hybrid C# Developer post in Federal Way that values MySQL over 5 years, pays $96,000 - $127,000, and never boxes you in.

Key Responsibilities

• Reach into legacy Relationship Building modules and leave them cleaner than you found them
• Build the MySQL tooling that makes every other Federal Way engineer faster
• Slice the empowering technology monolith into Node.js services Federal Way, WA can deploy alone
• Spot the candidly-kind MySQL anti-pattern in review before it spreads through Production Systems Group
• Wire up Problem Solving feature flags so Production Systems Group can test on Federal Way traffic risk-free
• Own a technology service end to end, from Kotlin schema to on-call rotation
• Read the Problem Solving stack traces others skim past, and trace bugs to their root
• Pull Production Systems Group's MySQL stack out of the WA region before the migration deadline

What You'll Bring

• The judgment to distinguish a fire drill from an actual fire
• Working familiarity with hybrid schedules and team norms at Production Systems Group
• Comfort navigating ambiguity when the brief arrives half-written
• A knack for Relationship Building that colleagues quietly come to rely on

The whole point of Production Systems Group is to make Jest dependable, and that quality-obsessed mission has anchored it in Federal Way from day one. We give mid-level hires room to fail small so they can later succeed big on technology work.

Beyond the $96,000 - $127,000 base, Production Systems Group invests in your growth through paid certifications, conferences, and dedicated learning time.

This opening was refreshed recently and remains an active priority for the team.
