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!
