Key Responsibilities

Backend Ownership

• Own the design, evolution, and reliability of mission-critical backend systems.
• Ensure scalability, performance, maintainability, and overall system health.
• Lead technical initiatives to address scaling challenges, technical debt, and architectural improvements.
  
  

System Design & Architecture

• Drive both High-Level Design (HLD) and Low-Level Design (LLD).
• Design scalable APIs, data models, service boundaries, and asynchronous workflows.
• Make sound engineering trade-offs balancing delivery speed with long-term system health.
  
  

Code Quality & Engineering Excellence

• Improve backend code quality through architecture reviews, code reviews, and refactoring.
• Simplify complex codebases and establish maintainable engineering patterns.
• Introduce best practices and guardrails to improve long-term maintainability.
  
  

Database & Performance Optimization

• Optimize PostgreSQL performance through schema design, indexing, query optimization, and tuning.
• Improve application performance using caching strategies and asynchronous processing.
• Design and operate analytics pipelines using ClickHouse or similar large-scale data systems.
• Work with messaging systems such as RabbitMQ or equivalent.
  
  

Technical Leadership

• Mentor backend engineers on architecture, debugging, and engineering best practices.
• Influence technical direction through thoughtful design discussions and strong technical reasoning.
• Raise overall engineering standards across teams.
  
  

Production Ownership

• Own production stability, incident management, and root cause analysis.
• Improve observability, monitoring, debugging, and operational excellence.
• Drive long-term reduction in production incidents and operational overhead.
  
  

Required Skills & Experience

Must Have

• 7+ years of backend engineering experience.
• Strong expertise in Node.js.
• Deep experience with PostgreSQL, including performance tuning and optimization.
• Experience designing and operating distributed backend systems.
• Strong understanding of system design, scalability, and microservices architecture.
• Experience owning backend services end-to-end—from architecture to production support.
• Strong debugging and problem-solving skills.
• Experience improving code quality, maintainability, and engineering standards.
  
  

Good to Have

• Experience with RabbitMQ or similar messaging systems.
• Experience with ClickHouse or large-scale analytics platforms.
• Experience deploying and managing applications on AWS.
• Strong knowledge of observability, monitoring, and production reliability.
  
  

What We're Looking For

Engineering Mindset

• Passion for improving existing systems rather than simply building new ones.
• Ability to simplify complex architectures and create maintainable solutions.
• Strong focus on writing clean, readable, and scalable code.
• Testing mindset with emphasis on reliability and long-term quality.
• Ability to evaluate technical trade-offs and design for future scalability.
  
  

Leadership Without Authority

• Influence technical decisions through expertise and clear reasoning.
• Challenge scope or timelines when necessary to protect system health.
• Mentor engineers and elevate overall engineering standards.
• Lead by example through hands-on technical excellence.
