Software Developer, Confluent

About the Role

We are looking for a Frontend Software Engineer to help build engaging, intuitive products for managing and visualizing large-scale, real-time data streams.

Key Responsibilities

• Help build client-side features for data-intensive products, working closely with senior engineers, designers, and product managers.
• Develop new features from user requirements and designs, taking on well-defined tasks within larger features, delivering them on time, refining them based on feedback, and growing the scope you own over time.
• Build UI components and interactions to design specifications using our design system.
• Integrate with backend APIs, working with backend engineers to understand API contracts and handle loading, error, and empty states.
• Write clean, readable code with unit and end-to-end tests.
• Write short design notes for tasks for peer review.
• Participate in code reviews, both receiving and giving feedback.
• Investigate and fix bugs and production issues, starting by shadowing the on-call rotation.
• Share progress clearly in standups and project updates, and raise blockers early.
• Learn Confluent's engineering practices, including release, monitoring, and feature flag processes, and how the product works end-to-end.

Requirements & Tech Stack

• The Cloud UI is built with React and TypeScript on our own design system.
• Connects to multiple REST and GraphQL APIs.
• Tests with Jest and React Testing Library (unit) and Playwright (end-to-end).
• Deploys to production daily and can test every commit, including PRs, before it goes live.
• Feature flags allow independent release from backend teams.
• Bots keep dependencies up to date.
• AI-assisted development tools are part of the everyday engineering workflow.

Qualifications

• 0.6 – 1 year of professional experience.
• Strong foundation in data structures, algorithms, and problem-solving.
• Strong JavaScript fundamentals, including asynchronous programming (promises, async/await), closures, and the DOM.
• Solid HTML and CSS skills, including responsive layouts.
• Good understanding of React (components, props, state, hooks, and component re-rendering).
• Basic understanding of frontend architecture: structuring components, managing state, and separating data fetching from UI.
• Experience building and bundling a frontend project with Webpack or a similar tool (e.g., Vite), including an understanding of modules, loaders, and code splitting.
• Comfort debugging with browser developer tools.
• Familiarity with Git and a pull-request-based workflow.
• Curiosity, eagerness to learn, and openness to feedback.
• Good communication and collaboration skills, with a team-first mindset.

Preferred

• Awareness of web accessibility and web performance (e.g., bundle size, Core Web Vitals).
• Experience with data visualization or charting libraries.
• Exposure to AI-powered workflows, agentic AI, or LLM-based applications.
• Internships, open-source contributions, hackathons, or personal projects.
• Interest in data streaming, Kafka, or distributed systems (no prior experience needed).
• Master's Degree.
