Job Description

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!

Expert Career Tips for Working Student / Intern: Software Engineer (Frontend & Backend) (f/m/x) Roles

To succeed in a competitive market as a Working Student / Intern: Software Engineer (Frontend & Backend) (f/m/x), you need more than just technical skills. Here are some expert strategies to elevate your profile:

• Build a Strong Portfolio: For technical roles, a clean GitHub or a personal project site is essential. For non-technical roles, a case study portfolio demonstrating problem-solving and impact is equally valuable. Show, don't just tell, what you have achieved in your previous positions.
• Master the Narrative: When interviewing, use the STAR method (Situation, Task, Action, Result) to structure your answers. Quantify your results wherever possible—mentioning "increased efficiency by 20%" is much more impactful than saying "improved efficiency."
• Continuous Learning: The industry moves fast. Whether it's staying updated with the latest AI tools or mastering a new management methodology, continuous professional development is key. Consider obtaining industry-recognized certifications that align with Working Student / Intern: Software Engineer (Frontend & Backend) (f/m/x) requirements.
• Networking: Connect with other professionals in similar roles. Join online communities, attend webinars, and engage in meaningful discussions on professional social networks. Often, the best opportunities come through referrals and community engagement.
• Soft Skills Matter: Communication, empathy, and leadership are often the deciding factors between two equally qualified technical candidates. Cultivate these skills as they are universally valued across all industries and seniority levels.

Additionally, research the specific company's culture and values. Tailoring your application to show how you align with their mission can significantly increase your chances of moving forward in the process.

Comprehensive Application Strategy & Hiring Process

Applying for a new role is a marathon, not a sprint. Follow this strategic approach to maximize your success rate:

1. Initial Research & Tailoring

Don't send the same resume to every employer. Spend at least 30 minutes researching the company. Look for recent news, their product roadmap, and their team structure. Modify your summary and core competencies to reflect the specific keywords found in the job description.

2. The Perfect Cover Letter

If the application allows for a cover letter, use it to tell a story that your resume cannot. Explain why you are passionate about this specific company and how your unique background makes you the perfect fit for the challenges they are currently facing.

3. Navigating the Multi-Stage Interview

Most modern hiring processes involve 3-5 stages. This typically includes a recruiter screen, a technical or skill-based assessment, a peer interview, and a final leadership round. Prepare for each stage differently: focus on enthusiasm and fit for the recruiter, technical depth for the assessment, and strategic vision for the leadership round.

4. Post-Interview Follow-Up

Always send a personalized thank-you note within 24 hours of each interview. Reference a specific topic discussed during the call to demonstrate your active listening and genuine interest in the role.

By following these steps, you demonstrate a high level of professionalism and attention to detail that sets you apart from the average applicant.

Typical Interview Process

1. Resume screening
2. HR call
3. Skill interview
4. Final manager interview

Tip: Research the company's products and culture.

Global Market Intelligence & Relocation Insights

At JobSetuu, we specialize in helping talent navigate the global job market. Here is what you need to know about the current landscape in Cologne and beyond:

The demand for skilled professionals is increasingly borderless. For roles based in Cologne, understanding the local cost of living, visa requirements (if applicable), and cultural nuances is vital.

When evaluating an offer, look beyond the base salary—consider the total compensation package, including equity, bonuses, and healthcare benefits.

Leveraging JobSetuu's tools can help you compare salaries across different cities and understand the "purchasing power" of your potential offer, ensuring you make an informed decision for your long-term career path.

Skills & Competency Roadmap for Professional Development

• AI Augmentation: Learn how to leverage generative AI and automation tools to increase your productivity. Understanding how to integrate these technologies into your workflow is becoming a non-negotiable skill.
• Leadership & Strategy: Even in individual contributor roles, the ability to think strategically and lead projects from inception to completion is highly valued. Focus on stakeholder management and high-level project planning.
