Senior Lead / Staff Engineer, FullStack (Gurugram)

About REA Group In 1995, in a garage in Melbourne, Australia, REA Group was born from a simple question: Can we change the way people experience property Thirty years later, REA Group is a global digital real estate leader operating across multiple continents, building large-scale, consumer-facing platforms used by millions every day. Our success comes from staying true to a day-one mindsetcombining innovation, curiosity, and long-term thinking to evolve complex systems that power critical customer journeys. REA Cyber City is an extension of REA Groups global technology organisation. Teams here work closely with counterparts in Australia and other regions to design, build, and operate core platforms and capabilities. Engineers in Cyber City contribute directly to REAs long-term technology strategy, solving real-world problems at scale and shaping systems that need to perform, adapt, and endure over time. If youre excited by the challenge of building resilient systems, working on meaningful problems, and growing with a global engineering organisationread on.

Solves domain-wide and cross-team technical problems. Enforces quality, standards, and strong engineering practices. Resolves complex dependencies across squads and systems. Influences technical strategy and represents engineering in decision forums. What youll do Technical Execution Design, build, review, and operate production-grade full-stack systems using modern engineering practices. Own delivery of complex, high-impact features and subsystems, leading by example in code quality, correctness, and performance. Work hands-on across frontend and backend codebases using technologies such as React, JavaScript, TypeScript, Node.js, and Java. Drive high engineering standards through pairing, deep code reviews, and clear technical guidance. Design & Architecture Own architecture decisions for complex systems, documenting and communicating trade-offs through design reviews and Architecture Decision Records (ADRs).

System Ownership & Operational Excellence Own production systems end-to-end, including reliability, scalability, performance, observability, and technical debt management. Own application performance across the stack by identifying bottlenecks, driving optimisations, and ensuring systems meet latency and scalability targets. Design and operate containerised workloads using Docker and Kubernetes in production environments. Ensure systems are observable, resilient, and designed for safe failure and recovery. Champion continuous improvement in operational practices and developer experience. Delivery Leadership Contribute to planning and sequencing of work, helping teams balance scope, quality, and delivery timelines. Identify cross-team dependencies and technical risks early, unblocking teams through sound technical decisions. Partner closely with Engineering Managers and delivery leads to improve predictability without compromising quality. Technical Leadership & Mentorship Mentor and coach engineers through design reviews, technical discussions, and hands-on guidance. Raise the technical bar across squads by reinforcing strong engineering practices and architectural consistency. Influence without formal authority, earning trust through technical credibility and clarity of thinking. What were looking for Proven experience operating as a senior contributor on complex, production systems. Strong hands-on experience with contemporary full-stack technologies, including React, JavaScript/TypeScript .
