Job description

The Frontend Developer we hire will help Merck pay down years of technical debt without anyone calling it a rewrite, using Multitasking sparingly and well. Count it up: 1 years, $68,000 - $113,000, a technology charter, and the kind of Merck growth that compounds.

Key Responsibilities

• Profile and refactor legacy code to reduce technical debt over time
• Hunt down the latency spikes nobody at Merck can explain
• Containerize applications and manage deployments with Multitasking and Redis
• Chase down the CI/CD integration that silently drops Merck events at midnight
• Collaborate with product and design teams to ship features end to end
• Guard the Cross-Functional Collaboration codebase quality through reviews that teach as much as they catch

What You'll Bring

• Strong rapport-building skills and a genuinely positive presence
• A portfolio or work samples that demonstrate your technology expertise
• The reflex to surface risk before it surfaces itself
• Comfort with part-time arrangements and the rhythms of a hardworking workplace
