They typically work under the supervision of experienced developers to learn and contribute to projects using various programming languages and frameworks.

What kinds of projects and technologies does a full stack development intern typically work on during their internship?

Full Stack Development Interns often contribute to both front-end and back-end features of web applications, working with frameworks like React or Angular for the user interface and Node.js, Python, or Java for server-side logic. Interns may be assigned tasks such as building new components, fixing bugs, writing APIs, or assisting with database integration. It's common to collaborate closely with designers, senior developers, and QA testers in an agile environment, gaining exposure to the entire software development lifecycle. This hands-on experience helps interns understand how different technologies interact and prepares them for more advanced roles in the future.

Familiarity with version control systems like Git, databases (SQL/NoSQL), and cloud platforms is often expected, and experience with tools like React, Node.js, or Docker can be advantageous.

Job description

We're looking for a senior full stack engineer to help build the core systems behind AI teammates for finance. You'll design and ship infrastructure that allows agents to initiate, execute, and complete real workflows across messy enterprise environments. This is not surface-level AI. You'll be working on systems that combine reasoning, context, and action in production.
What you'll do
  • Design and build end-to-end systems that power intelligent, outcome-driven workflows
  • Own features across the stack, from backend services to user-facing interfaces
  • Integrate AI models into reliable, auditable production systems
  • Work closely with product and customers to solve real finance and accounting problems
  • Build for scale, security, and enterprise-grade reliability from day one

What we're looking for
  • 5+ years of full stack development experience
  • Strong proficiency in Python
  • Experience with modern cloud platforms (AWS, Azure, or GCP)
  • Hands-on experience integrating AI/ML systems into applications
  • Background in enterprise software architecture and distributed systems

Why Numos
You'll be building systems that don't just assist work, but actually get it done. The problems are complex, the expectations are high, and the impact is real.
