They work under the guidance of experienced engineers to gain hands-on experience with programming languages, frameworks, and tools used throughout the software development lifecycle. Their responsibilities often include writing code, testing applications, fixing bugs, and collaborating with teams to deliver functional software. Through this internship, they develop practical skills and a deeper understanding of how web systems work end-to-end.

What are the key skills and qualifications needed to thrive as a full stack engineer intern?

To thrive as a Full Stack Engineer Intern, you need a solid understanding of programming languages like JavaScript, HTML, CSS, and at least one backend language, often supported by coursework or relevant project experience. Familiarity with frameworks such as React or Angular, backend systems like Node.js or Django, version control (Git), and basic database management is typically expected. Strong problem-solving skills, eagerness to learn, and effective communication help interns stand out in fast-paced development teams. These skills and qualities are essential for contributing to real-world projects, collaborating effectively, and accelerating professional growth in a technical environment.

Interns often assist with integrating APIs, database management, and testing features in both development and production environments. You'll likely collaborate closely with designers, product managers, and other developers, gaining exposure to the complete software development lifecycle. This hands-on experience is designed to help you build practical skills and contribute meaningful code to real applications.

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. 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.
Full-Stack Engineer (Denari)
Location: Madison, WI (Hybrid)
Employment Type: Full-time
About Denari
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.
The Role
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, please look elsewhere. Denari is for people who want to push themselves, grow quickly, and build something truly world-class.
What You'll Do
  • Move quickly on developing new products and features across Denari's suite.
  • Work in tight iteration loops with constant communication across design, product, and engineering.
  • Operate as part of a small, high-ownership team that values autonomy and accountability.
  • Bring a leadership mentality - push to improve team processes, raise standards, and help others level up.
  • Build and maintain end-to-end features using TypeScript, React/Next.js, PostgreSQL, and tRPC.
  • Partner closely with others engineers to transition parts of the existing Go-based infrastructure into a unified TypeScript platform.
  • Participate in architectural discussions and define best practices for scalability, maintainability, and security.
  • Be transparent, honest, and upfront in your communication.
  • Contribute to automation of compliance workflows, leveraging data and AI.
  • Use LLMs and modern AI tools in your workflow wherever they accelerate output or insight.

What You'll Bring
  • 3-6 years of full-stack development experience, or preferably exceptional growth and output in less time.
  • Mastery of TypeScript, with strong skill in React/Next.js and backend services using Node.js.
  • Experience with PostgreSQL and ORMs like Drizzle.
  • Deep understanding of API design, tRPC, or GraphQL.
  • Hands-on experience with CI/CD pipelines and cloud deployment (Vercel, AWS).
  • Proven ability to thrive in fast-moving, high-ownership environments.
  • Desire to continuously improve, learn fast, and deliver exceptional product quality.
  • Strong sense of product ownership and empathy for end users; you'll regularly talk with accountants, partners, and staff to understand their workflows and shape the product experience.

Nice-to-Have
  • Experience with Go (Golang) or migrating backends to TypeScript.
  • Background in accounting, workflow automation, or document management systems.
  • Experience working with LLMs, AI agents, or intelligent automation systems.

Why Join Denari
  • Build the foundation of a product transforming the accounting industry.
  • Work directly with founders and top firms.
  • In-person collaboration (3 days/week in Madison) with flexibility and autonomy.
  • Comprehensive benefits package including health, dental, vision, life, disability, 401(k) with match, 20 days PTO, and paid holidays.

Join us in building the intelligent accounting platform of the future. Apply at denari.ai/careers or email your portfolio and GitHub to careers@denari.ai.
