• Experience collaborating with technical teams and business stakeholders.

IMPORTANT: ENGLISH COMMUNICATION REQUIREMENTS

EXCELLENT SPOKEN AND WRITTEN ENGLISH IS MANDATORY.

Candidates must be able to communicate fluently, clearly, and confidently in English during technical interviews, team meetings, and discussions with stakeholders.

Applicants must demonstrate:

• ADVANCED OR FLUENT ENGLISH PROFICIENCY (C1 LEVEL PREFERRED).
• Excellent English listening comprehension and verbal communication.
• Clear, understandable pronunciation and the ability to explain technical concepts effectively.
• Ability to communicate technical decisions and reasoning in real time.
• Confidence participating in technical discussions entirely in English.

Candidates will be evaluated on communication clarity and comprehension, not on having a particular native or regional accent.

IMPORTANT: MANDATORY LIVE TECHNICAL INTERVIEWS

ALL CANDIDATES MUST BE COMFORTABLE COMPLETING LIVE CODING AND LIVE SYSTEM DESIGN INTERVIEWS IN ENGLISH.

Live Coding Interview

Candidates must demonstrate the ability to:

• Write working Python code in real time.
• Solve algorithmic and data structure problems.
• Implement APIs, data processing functions, and ML-related logic.
• Debug and optimize code during the interview.
• Explain their thought process clearly while coding.
• Discuss time complexity, scalability, and alternative solutions.

Live System Design Interview

Candidates must demonstrate the ability to:

• Design a scalable AI/ML system from scratch.
• Architect LLM applications, RAG pipelines, and AI agent workflows.
• Explain database selection, API architecture, caching, and distributed systems.
• Design cloud infrastructure and production deployment strategies.
• Discuss latency, scalability, security, reliability, and cost tradeoffs.
• Explain architectural decisions and answer follow-up questions confidently.

LIVE CODING AND LIVE SYSTEM DESIGN INTERVIEWS ARE REQUIRED PARTS OF THE HIRING PROCESS.

Candidates should be prepared to demonstrate their own technical skills without relying on AI coding assistants during the assessment unless explicitly permitted.

Preferred Qualifications

• Experience building enterprise-grade AI applications used by real customers.
• Experience with LLM fine-tuning, LoRA, QLoRA, and model optimization.
• Experience implementing multi-agent orchestration and autonomous AI workflows.
• Experience with NVIDIA GPUs, CUDA, TensorRT, or distributed model training.
