OVERVIEW
Releady is partnering with a leading specialty retailer of musical instruments, professional audio, and live event technology to hire a mid-senior ServiceNow Developer supporting the retailer's IT infrastructure organization. This role centers on the company's automated employee onboarding and offboarding platform, an integration between ServiceNow and ADP used across every retail store location — you will own fixes, design assistance, and problem and incident resolution for that integration — while also taking ownership of new automation and integration development across the broader ServiceNow platform, including new Integration Hub spokes and workflows beyond the ADP integration.
This is a hands-on, technically deep development role for someone who can both stabilize a live, business-critical integration and independently design and build new automations. The right candidate can trace a broken workflow back to its root cause and fix it cleanly, and can also architect a new integration from scratch when the business needs one.
Employment Type: Contract (6 months, with potential to extend)
Location: Remote — candidate must reside in Costa Rica
Compensation: $35–$40 per hour
NOTE: Candidate must be legally authorized to work in Costa Rica. This is a remote contract role supporting a US-based client and requires consistent overlap with US Eastern time business hours.
