POSITION DESCRIPTION:

Mirato is now a part of Sayari and is looking for a Technical Lead, AI Engineering. As a Technical Lead at Sayari, you will own the cross-section between classical NLP and modern LLMs. You will design, build, and scale internal AI services—combining spaCy/NLTK and keyword/BOW approaches with prompt-driven LLM agents—backed by robust Python services, ETL/ELT data pipelines, and PostgreSQL. You’ll partner closely with our data scientist to productionize models and continuously improve latency, throughput, and quality.

Job Responsibilities

• Ship internal AI Applications end-to-end: design APIs (FastAPI), write performant async Python, and deliver observability, tests, and CI/CD, including Database design to support those applications
• Own and maintain NLP/LLM pipelines that power internal services (prompt patterns, parameter tuning, fallbacks/guardrails, evaluation, inference)
• Develop and scale agents for LLM tasks (tool use, retrieval, routing, self-critique/verification)
• Collaborate with the data scientist to implement new capabilities, evaluate model quality, and move prototypes to production
  
  

• Python expertise: FastAPI, asyncio, ORM (e.g., SQLAlchemy), and hands-on performance work (profiling, async I/O, CPU vs. memory trade-offs)
• Classical NLP: spaCy, NLTK, BOW, keyword/regex pipelines; practical text normalization, tokenization, NER, and rule-based extraction
• LLMs: prompt/chain design, parameterization (temperature/top-p/max tokens), patterns (RAG, ReAct, CoT, tool use), and safety/guardrails
• Agents: experience building task-oriented LLM agents and evaluators; fallback strategies and observability for agent behavior
• Pipelines: Python ETL/ELT, workflow orchestration (Airflow/Prefect/Dagster or equivalent)
• Databases: PostgreSQL schema design, indexing, query optimization
• Testing: unit/integration/load testing, API contract testing; comfort with test data management and golden datasets
• Collaboration: mentoring, design reviews, structured debugging, and working across functions
  
  

• Mandatory Benefits provided including Statutory Pension, Study Fund, Monthly meal allowance
  
  

• Generous time off - 20 vacation days per year, paid public holidays as mandated by law, paid sick
  
  

• 1,000 ILS per new employee for home office equipment
• Holiday gifts for Rosh Hashanah and Passover (500 ILS Gift card)
• Outstanding compensation package; competitive commissions for revenue roles and quarterly
  
  

• A strong commitment to diversity, equity, and inclusion
• A collaborative and positive culture - your team will be as smart and driven as you
• Limitless growth and learning opportunities
