## Description

Experienced software engineers who drive real business impact - whether that's owning a product capability, leading a technical system, or shaping engineering strategy across teams. You've scaled through high-growth, you partner well cross-functionally, and you care about how a team builds, not just what ships.

We're building industry-defining accounting and finance software. We want engineers who bring a point of view to the work.

Our Tech Stack: Svelte 5/TypeScript frontend, Kotlin + Spring Boot backend, PostgreSQL, AWS. We're AI-native - meaning thoughtful application, not outsourced thinking. Our engineers still reason from first principles; AI helps with execution.

We're looking for teammates who are based near our New York City or San Francisco offices, or open to relocating. Our hybrid schedule brings the team together in person on Tuesdays and Thursdays, plus one additional flexible day each week. Some roles may spend more time in the office depending on the needs of the team.

What You'll Do

 * Own features and systems end-to-end across the full stack, from backend architecture to the interfaces users interact with every day
 * Partner with product, design, and finance experts to shape what we build - advocating for the right technical tradeoffs and keeping the customer perspective central
 * Raise the bar for engineering quality: continuous delivery, test-driven development, production reliability, and a culture of ownership
 * Grow the team around you through code reviews, mentorship, and hands-on collaboration
