SDE Intern - Backend at CloudSEK

CloudSEK is a fast‑growing cybersecurity startup that empowers organizations with AI‑driven threat detection. As a Backend SDE Intern, you will work on cutting‑edge security pipelines that protect millions of users, giving you exposure to real‑time data processing, large‑scale APIs, and industry‑standard security practices. The fast‑paced environment encourages ownership, so you’ll see your code ship to production early, receive mentorship from seasoned engineers, and contribute to products that have a tangible impact on global cyber‑defense. Beyond the technical growth, CloudSEK fosters a collaborative culture where learning is continuous. Interns are invited to weekly tech talks, hackathons, and mentorship circles that accelerate professional development. The Bengaluru office is a hub of innovation, offering networking opportunities with thought leaders in security, and a clear pathway to full‑time roles for high‑performing interns. This blend of challenging projects and supportive community makes the internship a launchpad for a rewarding career in backend engineering and cybersecurity.

Focus on data structures and algorithms fundamentals; CloudSEK’s interview often includes coding problems that test your ability to manipulate trees, hash maps, and graphs under time constraints. Practice writing clean, production‑ready code in Java or Python, and be prepared to discuss the time and space complexity of your solution. Additionally, review RESTful API design principles, HTTP status codes, and how you would secure an endpoint, as scenario‑based questions are common for backend roles. Prepare to demonstrate practical knowledge of Spring Boot or similar frameworks. Review how to set up a simple microservice, configure dependency injection, and write unit tests with JUnit or pytest. Be ready to discuss a recent project where you integrated a database, handled concurrency, or optimized a performance bottleneck. Show curiosity about cybersecurity by understanding basic threat models and how backend services can mitigate risks, which will differentiate you from generic candidates.
