Nice to Have * You have experience with complex data visualization (e.g., D3.js, Chart.js, or similar). * You have exposure to graph databases or graph query patterns (e.g., Neo4j). * You have experience with real-time streaming data and live system visualization. * You have worked in defense, security, or other mission-critical domains. * You have built UI experiences that surface AI/ML outputs in operational workflows. * You have experience contributing to component libraries or design systems (e.g., Storybook). ## Description You'll be a high-output engineer building mission-critical operator experiences - implementing complex, high-performance interfaces that visualize real-time cyber operation data with speed and precision. You'll contribute meaningfully to frontend architecture and design decisions, own significant features end-to-end, and raise the quality of the codebase around you. You'll work closely with other frontend engineers and cross-functional partners across backend, product, design, and operations to ship capabilities that must work reliably in both cloud and on-premises environments. Who You Are * You care about building software that has real-world impact in high-stakes environments. * You write clean, precise, and well-tested code and hold yourself to that standard without being asked. * You think carefully about performance, reliability, accessibility, and maintainability as you build. * You make sound tradeoffs under constraints and communicate them clearly to teammates. * You're drawn to complex data problems and enjoy turning them into interfaces that help users act quickly. * You take ownership of your work end-to-end - from design review to production - and take pride in delivering on your commitments. * You default to secure engineering practices and treat trust, safety, and correctness as non-negotiable. What You'll Do * Build sophisticated React/TypeScript features and components that operate reliably at scale. * Implement real-time UI experiences for complex cyber operation data, optimizing for speed and clarity. * Contribute to frontend architecture and design decisions alongside your teammates. * Build and maintain interactive visualization components (e.g., graphs, timelines, streaming views). * Write and maintain automated tests across unit, integration, and end-to-end layers. * Participate actively in code review - giving and receiving feedback that raises the quality bar. * Identify and address performance issues, technical debt, and reliability gaps proactively. * Collaborate with design, product, backend, and operations to deliver well-integrated features. * Support engineers through pairing and practical feedback on their work. ## Related Videos - [But, you're not Facebook](https://www.wearedevelopers.com/videos/378-but-you-re-not-facebook) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Putting the Graph In GraphQL With The Neo4j GraphQL Library](https://www.wearedevelopers.com/videos/257-putting-the-graph-in-graphql-with-the-neo4j-graphql-library) - [The Resilience of the World Wide Web](https://www.wearedevelopers.com/videos/1281-the-resilience-of-the-world-wide-web) - [Microfrontends at Scale](https://www.wearedevelopers.com/videos/236-microfrontends-at-scale) - [Git for Code Reviews](https://www.wearedevelopers.com/videos/429-git-for-code-reviews) ## Related Articles - [16 Best Free React UI Libraries in 2025](https://www.wearedevelopers.com/magazine/148-16-best-free-react-ui-libraries-in-2025) - [The Best 7 Frontend Frameworks for Developers in 2025](https://www.wearedevelopers.com/magazine/400-the-best-7-frontend-frameworks-for-developers-in-2025) - [React Developer Salary [2023]](https://www.wearedevelopers.com/magazine/198-react-developer-salary-2023) - [25 Essential Tools for Front End Developers](https://www.wearedevelopers.com/magazine/210-25-essential-tools-for-front-end-developers) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development) - [Frontend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/195-frontend-developer-salary-in-germany-2023)
