The Role

We're looking for a Software Engineering Intern to join our team and contribute to real, production-level projects. This isn't a "coffee-fetching" internship — you'll write code, ship features, and work alongside experienced engineers from day one.

What You'll Do

  • Build and maintain features across our web platform (frontend and/or backend)

  • Work on client-facing tools including dashboards, formation wizards, and integrations

  • Collaborate with the engineering team on system design and code reviews

  • Contribute to internal tools supporting our ERP, CRM, and partner systems

  • Participate in Agile ceremonies: standups, sprint planning, and retrospectives

  • Explore and apply AI-assisted development tools in your workflow

What We're Looking For

Must-have:

  • Currently pursuing a degree in Computer Science, IT, or a related field

  • Able to read technical documentation and communicate in English

  • Basic knowledge of Git and version control workflows

  • Strong willingness to learn, take ownership, and get things done

Preferred tech skills (any of the following):

Frontend: React, Next.js, Vue, Angular, or Svelte

Backend: Node.js / Express, Python / Django, Java / Spring, PHP / Laravel, or Go

Database: MySQL, PostgreSQL, MongoDB, Firebase, Redis, or Supabase

Other: REST or GraphQL APIs, Docker, CI/CD, AI/LLM integrations (OpenAI, LangChain), AI-assisted coding tools (Cursor, Copilot, Claude Code)

What You'll Get

  • Hands-on experience with real-world, production-grade projects

  • Mentorship from senior engineers in a fast-moving startup environment

  • Professional, English-speaking work culture with global exposure

  • Flexible start date and hybrid-friendly schedule

  • A strong path toward a full-time offer based on performance

We review applications on a rolling basis and will reach out within 5–7 business days.
