Our Culture

At Nomain, we are customer-obsessed. We work closely with our users to understand their challenges and build solutions that truly make a difference. Our culture is built on ownership, transparency and continuous learning. We’re a tight-knit, ambitious team that values curiosity, autonomy, and building things that matter. Everyone has a voice, and we’re united by a shared mission to solve complex problems with practical and impactful solutions.

What You’ll Do

As a Summer Intern in Software Development, you’ll join our engineering team working on cutting-edge AI product features that make a real impact. You will:

  • Contribute to the design and implementation of production-ready software components for our AI platform.
  • Work with our core stack, including .NET and C#, collaborating closely with experienced engineers.
  • Dive into AI-enabled features—building, testing, and refining algorithms that help extract insights from complex codebases.
  • Participate in code reviews, sprint planning, and daily team collaboration to deliver high-quality software.
  • Learn from real users: see your work tested, validated, and used in real enterprise workflows.

This role will give you hands-on experience building software at scale, with mentorship and responsibility from day one.

Who We’re Looking For

We’re seeking students who are:

  • At least in their 3rd year of university studies in Computer Science, Software Engineering, or a related field.
  • Comfortable coding in .NET and C# (experience with these is required).
  • Passionate about building quality software and keen to learn about AI-powered products.
  • Curious, independent, and eager to contribute ideas in a fast-moving startup environment.

Prior experience with cloud platforms or AI frameworks is a plus—but what matters most is your willingness to learn and build.

Why Join Nomain

At Nomain you’ll learn from a team that values autonomy, curiosity, and craftsmanship. You won’t be fetching coffee—you’ll build features that matter, push code to production, and help shape the future of our product and platform. You’ll be part of a collaborative culture where your work has direct impact on user experiences and business outcomes.
