Frontend Engineer - Internship

Certa is the AI-first third-party operating system. Enterprises, from the Fortune 500 to fast-growing startups, use our no-code platform to onboard, assess, and monitor their vendors, suppliers, and partners across risk, compliance, and ESG. We have processed over 10 million entities for 100,000+ users across 120+ countries, and are backed by Fin Capital, Vertex Ventures, and Point72 Ventures. This is a paid 3-month internship with the opportunity to transition into a full-time role at the end based on performance. You'll build the interfaces enterprise users interact with every day, shipping real features to real customers from your first sprint, with real ownership and direct mentorship from senior engineers. What You'll Do Build UI components: Develop pixel-perfect, highly interactive UI components in React. Turn designs into code: Translate Figma designs into production-ready code, and push back when the design doesn't make sense. Own performance: Care about load times, re-renders, and bundle sizes. Collaborate on APIs: Work with backend engineers to define APIs and data contracts. Ship end-to-end with quality: Write component tests, maintain a high standard for code quality, and ship features end-to-end, not just the "frontend part." What You'll Need JS/TS fundamentals: A solid grasp of JavaScript/TypeScript fundamentals: closures, async, and the event loop. React: Working knowledge of React: hooks, state management, and component lifecycle. Real project experience: You've shipped something real to the web (even if small) and gone beyond tutorials: thoughtful state management (what lives where and why), API integration with loading/error/auth handling, forms with client- and server-aware validation, multi-page routing (nested and protected routes, query params), or working with a component library or design system. Debugging & performance: You can look at a broken UI and fix it without being told where to start, and you've used browser DevTools to spot and fix a slow render. Quality & UX: You care about accessibility, responsiveness, and edge cases, not just happy paths, and you have opinions about UX that you're not afraid to voice. AI-assisted building: You use AI tools (Copilot, v0, or similar) to build faster, and know when a suggestion is right and when it's subtly wrong. Internship Details & What You Get Duration: A paid 3-month internship, with the opportunity to transition to a full-time role at the end based on performance. Compensation: Competitive compensation, benchmarked above market for fresher roles. The work: Complex, high-stakes enterprise UIs - enterprise software done right - with your code shipping to real customers quickly. Mentorship & impact: Direct mentorship from senior engineers who push you to grow fast, and real ownership from day one. Location Certa is a remote-first company and we hire globally.
