Tech Lead / Architect - HO

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

• 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
