About Us:

Virtwin-Energy AB is an early-stage EdTech/Saas start-up building our core product Ignite-AI - an Artificial Intelligence Combustion Science and Engineering Cloud Platform

Our Vision: We envision a world where every engineer, researcher, and student can easily access professional-grade tools for combustion science, fuel innovation, and energy system design — no more expert-only interfaces

Our Mission: We are building the first AI-native combustion and techno-economic cloud platform, where industries, researchers, and students can collaborate, innovate, and accelerate the shift toward sustainable energy effortlessly

The Role:

We're looking for a Backend AI & Web Developer (Co-Founder) to join our small, expert team. You'll help build the backend and AI systems driving Ignite-AI, working hands-on with cutting-edge tech and shaping the product beyond the MVP.

What You'll Do:

  • Build and maintain backend systems using Python (Django)
  • Integrate AI and LLM workflows with Hugging Face, PyTorch, LangChain, LangGraph, etc.
  • Design APIs and connect backend services with React frontends
  • Work in Linux or WSL environments
  • Bring creative flow and vibe coding to a collaborative, high-energy team

What We're Looking For:

  • Vibe coding skill is a must — be ready to show your fluency during the interview
  • Knowledge of combustion physics is required, or at minimum, an engineering background.
  • Other merits:
  • 1–3 years of experience in backend or AI web development.
  • Strong Python/Django and API skills.
  • Experience with modern AI frameworks (Hugging Face, PyTorch, LangChain, LangGraph).
  • Basic knowledge of HTML/CSS/React/MongoDB.
  • Comfortable on Linux or Linux-in-Windows setups.
  • Self-driven, curious, and team-oriented.

What We Offer:

  • StockOptions (unpaid internship phase → potential Lead Developer role)
  • Car transportation to the office is provided for occasional meetings.
  • Build a real AI/EdTech/SaaS product beyond the MVP.
  • Flexible hybrid or remote setup

Our Journey:

Our MVP Ignite-AI is live, offering early combustion and energy modeling features. We're expanding capabilities, joining an incubator, and preparing for seed funding. Join us early and help shape the future of AI-driven energy innovation.

Ready to build something meaningful?

Apply now and join Virtwin-Energy AB — where AI, coding, and sustainability meet.
