  • Optimize and Improve Existing Systems: Continuously monitor and optimize backend performance. Identify bottlenecks and implement improvements to enhance efficiency, scalability, and the reliability of AI-powered systems.
  • Ensure Code Quality: Write clean, maintainable, and efficient code. Conduct code reviews and provide constructive feedback to peers.
  • Implement Security Best Practices: Ensure backend systems are secure and comply with industry standards and regulations.
  • Mentor Junior Engineers: Provide guidance and mentorship to junior team members to help them grow their technical skills and career.

Qualifications
  • Experience: 5+ years of experience in backend development, with a strong focus on building scalable and robust systems. Proficiency in languages such as Python or Node.js. Experience building AI-powered products, agentic systems, or engineering tooling / harnesses is strongly preferred.
  • Technical Skills: Deep understanding of databases (SQL and NoSQL), RESTful APIs, microservices architecture, and cloud platforms (AWS, Azure, or GCP). Familiarity with LLM-based systems, orchestration frameworks, evaluation pipelines, or related AI infrastructure is a plus.
  • Problem-Solving: Strong analytical and problem-solving skills to identify issues and implement effective solutions.
  • Collaboration: Excellent teamwork and communication skills to work effectively with cross-functional teams.
