Keep the world awake - Build the backbone of agentic incident response
ilert is the heart of the "always-on" business. Our backend systems process thousands of events per second, ensuring that when a critical system fails, the right person is notified within seconds.
We are looking for a Working Student or Intern who wants to go beyond "Todo List" apps and dive into high-performance, distributed backend architecture. You will help us build the resilient APIs and data processing pipelines that power our platform across AWS, Kubernetes, and beyond.
<h2>Tasks</h2>
<ul>
<li>API Development: Design and implement robust RESTful APIs using modern backend languages (we mainly use Java and Rust - we're happy to see your preference!).</li>
<li>Scalable Systems: Help us optimize our data ingestion pipelines and work with distributed systems like Kafka and ClickHouse.</li>
<li>Database Management: Work with SQL and NoSQL databases to ensure data integrity and high performance at scale.</li>
<li>AI &amp; Automation: Support our AI SRE agent team by building the backend logic that enables automated incident resolution.</li>
<li>Testing &amp; Reliability: Write comprehensive unit and integration tests to ensure our services are mission-critical ready.</li>
<li>Flexible Impact: Depending on business needs and your interest, you could work on anything from core alerting logic to complex integrations with third-party tools (Slack, MS Teams, Jira).</li>
</ul>
<h2>Requirements</h2>
<ul>
<li>Current Student: Enrolled in Computer Science, Software Engineering, or a related field.</li>
<li>Coding Foundation: You are proficient in at least one backend-heavy language (e.g., Go, Java, Python, or Node.js) and understand OOP or functional programming principles.</li>
<li>Database Basics: You know your way around SQL and understand how to design efficient data models.</li>
<li>CS Fundamentals: You have a solid understanding of algorithms, data structures, and how web servers work.</li>
<li>Curiosity: You are interested in distributed systems, microservices, and "The Cloud."</li>
<li>Language: Fluent English (our working language).</li>
</ul>
<h2>Benefits</h2>
<ul>
<li>🚀 Deep Tech: Solve real engineering challenges involving high availability and low latency.</li>
<li>🏡 Hybrid Freedom: Join us in our Cologne Rheinauhafen office (3 days/week) and work from home (2 days/week).</li>
<li>🕒 Your Studies First: We offer flexible scheduling to accommodate your lectures and exam seasons.</li>
<li>🎓 Elite Mentorship: Work alongside senior engineers who have built systems at scale and are eager to mentor you.</li>
<li>🌴 Focus Culture: We protect "maker time," prioritize deep work, and keep our meeting overhead low.</li>
</ul>
We value potential over perfection. If you love solving complex logic puzzles and building systems that "just work," we’d love to see what you’ve built!
