Time zone & Availability

Our teams are distributed across the United States and India. To ensure effective collaboration, this role requires a minimum of 3 hours of overlap with the U.S. Pacific Time Zone (PT) each workday.

• U.S. Pacific Time (PT): Standard working hours are typically 9:00 AM – 6:00 PM PT.
• India Standard Time (IST): PT is 12.5 hours behind IST (13.5 hours during U.S. daylight savings).
• This means candidates in IST must be available for overlap between 9:30 PM – 12:30 AM IST (or 8:30 PM – 11:30 PM IST during U.S. daylight savings).
• This overlap window is essential for daily communication with U.S.-based leadership, product managers, and engineering peers. Outside of these hours, engineers are free to structure their day flexibly to maximize productivity.
