Senior Software Engineer, Full Stack

Postscript (YC W19) | Senior Software Engineer, Full Stack | REMOTE (US, Canada) | Full-time | $180K to $220K base + equity

Postscript is an agentic retention marketing platform (SMS, RCS, Email) used by 20,000+ Shopify brands. We’re Series C and pacing toward profitability.

We’re rebuilding the platform from the ground up in Rust for the AI era, so the work mixes real scale problems (high-throughput messaging, deliverability, data pipelines) with a ton of 0 to 1 greenfield work where you shape the architecture.

Looking for senior engineers comfortable across the stack who are excited about Rust and like owning problems end to end. Fully remote team of ~250.
