Software Engineer, Full Stack Developer

At Denari, we’re building the super app for accounting firms—integrating everything in one place and leveraging AI to deliver major time savings. We’re a well-funded startup with 9 employees and a sister company to Lucida, with shared ownership and control, along with several additional firms that together generate over $100M in revenue. We’re also collaborating with a multi-billion dollar public company to develop a cutting‑edge chat system for customer support.

At Denari, our culture is defined by a high degree of autonomy and a fast‑paced, high‑pressure environment that rewards initiative. We work on interesting, transformative projects that challenge the status quo, and every team member has the freedom—and responsibility—to drive their own success. If you’re passionate about building cutting‑edge technology and thrive when the stakes are high, you’ll find a dynamic, collaborative home here where innovation is the norm and every day brings new challenges.

We are a team distributed across the US, but typically gather once per quarter in‑person.

Denari is building the modern software stack for accounting firms — an intelligent, AI‑powered operating system that unifies client collaboration, document management, workflow automation, and financial insights in one seamless platform.

Accounting work today is deeply fragmented — across dozens of disconnected tools and tasks, creating inefficiency, training challenges, and limited visibility for firm leaders. Denari solves this by providing a unified platform for firms — one place to collaborate, manage engagements, automate workflows, and surface insights.

Our north star:
save firms as many compliance hours as possible so accountants can focus on advisory work that drives higher margins and stronger client relationships.

We’re a well‑funded, fast‑moving company with shared ownership alongside Lucida , a mid‑sized accounting firm in Wisconsin. We are product‑ and talent‑driven, with a high bar for execution and growth.

We’re looking for world‑class engineers — 
builders in the top 1% of their craft. You’ll join a team that moves fast, holds a high bar, and expects intensity, curiosity, and rapid learning. If you learn quickly, work hard, enjoy craft, and love building elegant systems that solve complex real‑world problems, you’ll fit right in.

If you’re seeking a stable, slow‑paced role that prioritizes work–life balance above all else,
