CloudSEK, one of India’s most recognised cybersecurity product companies, is hiring a Frontend SDE Intern for its Bengaluru office. The work is on CloudSEK’s own product suite (XVigil, BeVigil, SVigil, and AIVigil) real threat intelligence platforms used by enterprise customers, not internal tooling or mock projects.
The role requires hands-on ReactJS experience and a solid grip on JavaScript fundamentals: OOJS, component architecture, state management, and CSS with tools like Webpack and Sass. If you’ve built React applications beyond tutorials and can speak to how you’ve structured components and managed state, this is a strong internship to target. If React is still on your learning list, apply after you have a project or two to show.
One practical point: this is 4 days a week in CloudSEK’s Bengaluru office. It’s listed as 3–6 months duration. Factor both in before applying.

About CloudSEK
CloudSEK was founded in 2015, is headquartered in Singapore, and has grown into one of India’s most prominent AI-driven cybersecurity product companies. Its platform monitors digital assets, attack surfaces, software supply chains, and, its newest product, AI infrastructure itself (AIVigil tracks exposed MCP servers, vector databases, leaked AI credentials, and agentic workflows).
In 2025, CloudSEK raised $19 million led by Tenacity Ventures and Commvault. For an intern, that funding runway and product momentum matter. This is a company in active growth, not maintenance mode.
What You’ll Work On
You’ll be building frontend features on CloudSEK’s live product suite: dashboards, threat intelligence interfaces, and monitoring tools used by real enterprise customers. This isn’t a sandbox environment.
Specific work areas will involve:
- Building and maintaining React components across CloudSEK’s product interfaces
- Working with stateful (container) and stateless (presentational) component patterns
- Implementing CSS architectures that fit ReactJS application structure
- Using tools like Webpack, Babel, and Sass in the build pipeline
- Collaborating with product and engineering teams on feature development and bug fixes
Eligibility & Skills Required
Technical Skills
| Skill Area | What to Know |
|---|---|
| JavaScript | Hands-on OOJS experience — closures, prototypes, async patterns, and how JS libraries work under the hood |
| ReactJS | Practical experience building React applications — component design, props, state, lifecycle, hooks |
| Component Architecture | Clear understanding of container vs presentational components and how to decompose a UI into a maintainable structure |
| CSS & Styling | CSS architectures (BEM, CSS modules, or similar) that work with React; familiarity with Bootstrap or similar frameworks |
| Build Tools | Working knowledge of Webpack, Babel, and Sass — not deep expertise, but comfortable using them in a project |
| Basics | HTML5, CSS3, jQuery — standard frontend fundamentals |
Who Should Apply?
- Students or freshers who have built at least one end-to-end React application: a real project, not a tutorial follow-along
- Candidates who understand how React’s component model works and can explain their architecture decisions
- Those who can commit to 4 days/week in CloudSEK’s Bengaluru office for 3–6 months
- Candidates interested in working in a cybersecurity product environment: the domain is niche and the exposure is valuable if you’re considering security-adjacent careers
Who Is This Role Not For?
- Candidates whose React experience is limited to online courses with no independent project to show: the JD asks for hands-on experience, and the interview will probe it
- Students who cannot come into Bengaluru at least 4 days a week. This is explicitly not a remote role
- Those looking for a backend, full-stack, or data engineering internship. This is purely frontend
Stipend
CloudSEK describes the compensation as “competitive salary” without disclosing a figure. Confirm the stipend at the offer stage. Use our Freshers In-Hand Salary Calculator to estimate your monthly take-home once you have the number.
Perks & Culture
- Flexible working hours
- Free food, snacks, and drinks at the office
- Collaborative culture where interns can pitch and implement their own ideas
- Regular team activities, games, and events
- Direct exposure to experienced engineering and product teams in a high-growth cybersecurity company
Selection Process
CloudSEK hasn’t published a formal selection flow for this listing. For a frontend SDE intern role at a product company, expect:
- Resume and portfolio screening: React projects and GitHub links reviewed first
- Technical assessment or assignment: likely a small UI component task or coding problem in JavaScript/React
- Technical interview: component design, JS fundamentals, state management, and a walkthrough of your past project
- HR or culture fit discussion: practice your opening introduction using our guide on how to answer “tell me about yourself” as a fresher.
The technical interview will almost certainly anchor on a project you’ve built. Be ready to walk through your component structure, how you managed state, and what you’d do differently now.
