About the Role

We are seeking a senior-level Fractional Backend Engineer to maintain, stabilize, and support a complex production system with multiple services and integrations.

This is a backend-first role focused on maintenance, debugging, and reliability. While the primary responsibility is backend work, there may be occasional frontend involvement to support debugging, integration fixes, or small adjustments related to backend changes.

This role requires strong ownership, accountability, and clear documentation of work performed.

• Occasionally assist with frontend-side changes related to backend behavior (debugging, integration fixes, minor updates)
• Communicate clearly about root causes, fixes, and risks
• Maintain detailed, descriptive time logs for all work performed

Accountability & Time Tracking (Required)

• Time must be tracked using an approved tool (Upwork tracker, Toggl, Harvest, etc.)
• Each time entry must include:
• Issue or task worked on
• Repository or system affected
• Brief description of work performed
• Weekly written summaries of work completed are required

Time entries without sufficient detail may not be approved.

Required Experience

• Comfortable owning production systems
• Disciplined about time tracking and documentation
• Reliable and responsive when issues arise

Please include:

• Summary of backend maintenance experience
