- Lead backend development using Node.js/TypeScript, ensuring clean, maintainable, and high-performance code
- Design and optimize data models across RDBMSandNoSǪLsystems
- Make key decisions around system design, trade-offs, and technology choices
- Ensure systems are built for scalability,faulttolerance,anddistributed operation
- Establish patterns for caching, concurrency control, and performance optimization
- Own system reliability: monitoring, observability, incident handling, and recovery strategies
- Define and enforce best practices for security,authentication,anddata protection
- Contribute to frontend architecture where necessary for end-to-end system coherence
Team Leadership G Delivery
- Lead and mentor a small,high-impactengineeringteam(2–6engineers)
- Drive execution by breaking down complex initiatives into clear deliverables
- Conduct code reviews, design reviews, and enforce engineering standards
- Set architectural guidelines, coding practices, and development workflows
- Actively unblock team members and provide technical direction
- Own delivery timelines, quality, and outcomes of the team
- Collaborate with product, design, and stakeholders to align technical execution with business goals
- Participate in hiring, onboarding, and mentoring engineers
- Foster a culture of ownership, accountability, and continuous improvement
Cloud G Infrastructure
