Tech Lead / Architect - HO

Description Role Overview We are looking for a highly technical, hands-on Tech Lead to build and lead a Core Engineering Team that operates across all R&D squads. This team will act as a force multiplier - solving complex system challenges, driving architectural improvements, and enabling development teams to move faster with higher quality. This is a deeply hands-on role (50%) , combining system design, architecture, and execution in a data-critical, high-scale environment . What Makes This Role Different Not a feature team - focus on system-level problems Not a traditional manager - strong hands-on ownership Not advisory - drives and executes real changes in production Works across teams - true cross-team impact Responsibilities: Cross-Team Technical Leadership Lead a Core Team working across multiple squads Identify system-wide bottlenecks, risks, and architectural gaps Drive alignment on engineering standards and best practices Partner closely with Tech Leads, Product, and Dev teams Architecture & System Design Own and evolve system architecture (Monolith → Modular / Services) Reduce tight coupling and improve system boundaries Lead major refactoring and modernization efforts Ensure scalability, performance, and resilience Microservice architecture (from modular monolith to microservices) Hands-On Development (70%) Write complex production code across services Lead by example in code quality and design Take ownership of the most challenging technical problems Engineering Excellence & Enablement Define and enforce development standards (Code Reviews, Design Patterns) Improve observability (monitoring, logging, alerting) Build reusable tools, infrastructure, and shared components Enable teams to deliver faster with higher quality Advantage for AI driven standard validations Mentorship & Technical Growth Mentor engineers and Tech Leads across teams Raise the engineering bar across the organization Support teams in production debugging and solving complex production issues Tech Stack Backend: Node.js, (Express,nestJS), PHP (advantage) Frontend: React, Redux, React Hooks Data: MySQL, SQL, Redis Infrastructure: AWS Advantage: Experience with agent frameworks (agentic flows) Requirements Requirements 5+ years of backend / full-stack development experience 3+ years system architecture experience Strong hands-on experience with Node.js in production for heavy load systems Proven experience in system design and architecture Experience working with scaling systems Strong experience with: Performance optimization Refactoring legacy systems Designing modular architectures Hands-on experience with AWS Strong understanding of data consistency, reliability and strategy Experience leading technical initiatives across teams Excellent communication and influence skills Advantage : Background in financial / billing systems Nice to Have Experience with event-driven architecture / queues Experience breaking down monoliths into services Experience building internal platforms / enablement teams Success in This Role Teams deliver faster with fewer blockers System architecture becomes more scalable, modular and stable Production stability and observability improve Engineering standards are consistent and adopted The Core Team becomes a trusted partner across R&D Why Join Us Real architectural challenges with direct business impact Opportunity to shape system foundations at scale High ownership and influence across the organization Work with strong teams in a growing product environment
