Working Student / Intern: Software Engineer (Frontend & Backend) (f/m/x)

Cologne, Germany (Hybrid) Team: Engineering · Reports to: CTO · Format: Working Student (16–20h/week) or Internship (3–6 months) Keep the world awake - build the platform thousands of DevOps teams rely on ilert helps thousands of DevOps & IT teams detect, fix, and communicate incidents faster. When a critical system goes down, our platform is the "source of truth" — from the resilient backend that processes thousands of events per second to the fast, intuitive frontend engineers stare at under pressure. We are looking for a Working Student or Intern who loves building software and doesn't want to be boxed into a single layer of the stack. Whether you lean frontend, backend, or full-stack, you'll ship production code that powers a mission-critical SaaS product.

We match projects to your strengths and our business needs — and we're happy to help you grow in whichever direction excites you most.

• Tasks Ship End-to-End Features: Build user-facing features with React and TypeScript , the backend APIs behind them, or both.
• Backend & Scale: Help design robust APIs and data pipelines in our backend stack (we mainly use Java and Rust ) and work with distributed systems like Kafka and ClickHouse .
• Frontend & Craft: Contribute to our modular component library and help keep the UI fast, accessible, and rock-solid when customers need it most.
• Flexible Project Scope: From core alerting logic to integrations (Slack, MS Teams, Jira) to AI-powered SRE features — we'll match the work to your interests.
• Quality & Reliability: Write tests and care about clean, maintainable code on a platform where downtime isn't an option.
• Requirements Current Student: Enrolled in Computer Science, Software Engineering, Informatics, or a related technical field.
• Coding Foundation: Hands-on experience with at least one part of our stack — React/TypeScript on the frontend and/or a backend language like Java, Go, Rust, Python, or Node.js .
• CS Fundamentals: A solid grasp of data structures, algorithms, and how web applications fit together (APIs, databases, Git).
• Engineering Mindset: You value clean, maintainable code and are eager to learn how a professional SaaS product is built, tested, and deployed at scale.
• Curiosity & Builder Mentality: Bonus points for side projects, open source, or anything you've built and shipped — backend, frontend, or AI.
• Language: Fluent English (our working language).
• Benefits High Impact: Your code helps engineers at companies worldwide stay calm and efficient during incidents.
• Pick Your Path: Explore frontend, backend, or full-stack — and find what you love before you graduate.
• Hybrid Freedom: Experience our beautiful office in Cologne Rheinauhafen (3 days/week) and work from home (2 days/week).
• Student-Centric: Flexible hours that work around your lectures and exam periods.
• Elite Mentorship: Work directly with experienced engineers who love to share what they know.
• Focus Culture: We protect "maker time," favor async communication, and keep meeting overhead low. We hire for talent and a "builder" mentality, not just a checklist. If you have a GitHub repo or a project you're proud of — a slick UI, a fast API, or an AI experiment that connects to the real world — we definitely want to see it!
