And we're just getting started.Backed by Greylock and Y Combinator, fully remote since 2018.As a Senior Software Engineer at Postscript, you'll be a high-ownership contributor to one of our core product or platform teams — owning meaningful systems end-to-end, driving technical quality, and helping shape how we build across the organization. Our engineering teams operate at the intersection of scale and product velocity, which means you'll be working on distributed systems that matter to the business while also influencing the technical standards that allow Postscript to grow sustainably.This is a high-autonomy role for engineers who are energized by ambiguity, take genuine ownership of their work, and bring a strong point of view on how to build things well — without sacrificing speed or pragmatism. AI isn't a nice-to-have here — it's central to how we work.
