Job description

Our Company
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.
Our Culture
At Denari, our culture is defined by a high degree of autonomy and a fast-paced, high-pressure environment that rewards initiative.

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.
What you'll do
As a Product & Software Intern at Denari, you'll have the opportunity to contribute directly to building innovative features that shape the future of our platform. You'll work on real projects, using data to guide design and implementation decisions, and collaborate closely with engineers and product teams. This internship is a hands-on experience where your work will have tangible impact, giving you exposure to both product strategy and software development in a fast-paced startup environment.

  • Curious and eager to learn through hands-on experience
