Jobbeschreibung

At Archtexx Consulting, we build intelligent and scalable software solutions that deliver real business value. We’re looking for a Junior Software Developer who’s eager to learn, contribute, and grow into a well-rounded full-stack engineer.

You’ll work with a small, experienced team on projects that combine React + TypeScript, Python (FastAPI), and AI/LLM agents. You’ll contribute across the stack — from frontend interfaces to backend APIs and database design — while developing good engineering practices and product sense.

Tasks

• Develop and maintain full-stack applications using React + TypeScript and Python (FastAPI)
• Help integrate AI/LLM agents into applications
• Write clean, maintainable, and testable code
• Contribute to automated testing (unit, integration, e2e)
• Design and optimize PostgreSQL schemas and queries
• Support CI/CD pipelines using GitHub Actions and help with basic infrastructure tasks
• Collaborate closely with product, design, and business teams
• Learn and contribute to architectural and technical decisions

Requirements

We’re not looking for someone with years of experience — we’re looking for someone with solid fundamentals, a learning mindset, and some hands-on experience (through work, study, or projects).

• Good understanding of React and TypeScript (hooks, component-based architecture)
• Some experience building backends in Python (FastAPI preferred, but Flask/Django also fine)
• Exposure to testing frameworks
• Frontend: Jest, React Testing Library, or Cypress
• Backend: Pytest or similar
• Familiar with PostgreSQL and basic SQL
• Comfortable using Git and GitHub
• Strong communication skills in German (C1/C2) and English
• Curious, proactive, and eager to learn new tools and technologies

Benefits

• Salary range: €40,000 – €50,000 per year (based on experience and skill level)
• Autonomy from day one - you’ll own your work, not just execute tickets
• A supportive and pragmatic team with direct mentorship from senior engineers
• Exciting projects in software, automation, and AI
• Benefits including Mobility, Lunch, Voucher, Internet Allowance, and Relaxation Vacation

If you’re a hands-on developer who enjoys solving real problems and wants to grow your skills in a modern, product-focused environment, we’d love to hear from you!
