Senior Frontend Developer / Tech Lead
R&D – Tel Aviv / Ra'anana (Hybrid)
DriveNets is a leader in cloud-native networking software for hyperscalers and service providers building the world’s largest infrastructures for network services and AI platforms. Founded in 2015, DriveNets disrupted high-scale networking markets by transforming how networks are built, scaled, and consumed. Today, more than half of AT&T’s backbone runs on DriveNets’ Network Cloud.
With $587M raised across three funding rounds, we are scaling fast and building a world-class engineering organization to support our continued growth.
The Role
We are looking for a Senior Frontend Developer to join our group, where we build scalable, high-performance systems that manage complex network infrastructures at massive scale.
In this role, you will take end-to-end ownership of a core domain within our application - an area defined by complex user workflows, intricate application logic, and high-scale data interactions. You will be responsible for shaping its technical direction, ensuring architectural soundness, and building the foundation that enables the domain to evolve alongside a broad and ambitious roadmap.
This is a high-impact position that requires strong technical judgment, long-term thinking, and a commitment to engineering excellence in a fast-paced, collaborative environment.
Responsibilities
· 10+ years of experience building modern, production-grade frontend applications.
· 5+ years of hands-on experience building large-scale applications with React in production.
· Deep expertise in JavaScript and TypeScript, including async patterns, event loop, memory management, and advanced type modeling.
· Strong understanding of React architecture and modern patterns (hooks, context, suspense, concurrent features, composition patterns).
· Proven experience designing and implementing scalable frontend architectures.
· Experience managing complex client-side state (Redux, Zustand, or similar).
· Experience building complex, dynamic UIs with intricate workflows and advanced interaction patterns.
· Hands-on experience integrating real-time data streams (WebSockets / SSE).
· Strong knowledge of performance optimization techniques (code splitting, memoization, virtualization, lazy loading).
· Experience writing comprehensive unit and E2E tests (Jest, Playwright or similar).
· Strong CSS/SCSS knowledge, including layout systems and responsive design.
· Experience working in cross-functional Agile teams with strong communication skills.
Nice to Have
· Experience building graph-based or visualization-heavy interfaces (e.g., React Flow, D3, Cytoscape).
· Experience building or contributing to shared component libraries or design systems.
· Experience working in distributed or cloud-native environments.
· Prior ownership of a technical domain or subsystem.
· Experience with monorepos (Nx / Turborepo).
· Familiarity with containerized development environments (Docker/Kubernetes).
Education
BSc in Computer Science, Software Engineering, or a related field — or equivalent hands-on experience.
