Svitla Systems Inc. is looking for a Senior AI and ML Engineer for a full-time position (40 hours per week) in Mexico, Argentina, Chile, Colombia and Costa Rica. Our client is a leading expert network that provides business and government professionals with opportunities to communicate with industry and subject-matter experts to answer research questions. Customers consult with these experts over the phone and in person at conferences, teleconferences, custom events, and workshops. Their multinational customer list includes nine top 10 consulting firms, hundreds of hedge funds, and many of the largest private equity firms and Fortune-ranked companies.

This strategic investment is integral to the company's vision for the future, aiming to develop cutting-edge Generative AI and analytical capabilities that will underpin the Next-Gen research enablement platform and data products. This role demands exceptional leadership and technical prowess to drive the development of next-generation research enablement platforms and AI-driven data products. You will develop and scale Generative AI-powered systems, including large language model (LLM) applications and research agents, while ensuring responsible AI integration and best-in-class MLOps. The Senior AI/ML Engineer will be a primary contributor to building scalable AI/ML capabilities using Databricks and other state-of-the-art tools across all the client's products. The team thrives on solving problems and making users happier. As they work to achieve their mission of creating individuals, businesses, and the world smarter through personalized knowledge-sharing solutions, the engineering team is tackling challenges to improve the internal application architecture and develop new AI-enabled products to optimize seamless service delivery.

REQUIREMENTS:

• A Bachelor's degree in Computer Science, Engineering, or a related technical field with 6+ years of professional experience; or a Master's degree with 4+ years of professional experience in backend software engineering and Generative AI. It must include a proven track record of designing, building, and scaling distributed, production-grade systems.
• Strong knowledge of Python, a major backend framework (e.g., FastAPI, Flask), and asynchronous programming (e.g., asyncio). Deep understanding of designing RESTful APIs, microservices, and the complete operational lifecycle, including comprehensive testing, CI/CD (e.g., ArgoCD), observability, monitoring, alerting, maintaining high uptime, and executing zero-downtime deployments.
• Hands-on experience deploying and managing applications on a central cloud platform (Azure preferred, AWS/GCP acceptable) using containerization (Docker) and orchestration (Kubernetes, Helm).
• 2+ years of experience building applications that leverage large language models from providers like OpenAI, Anthropic, or Google Gemini. Direct experience with modern LLM patterns such as retrieval-augmented generation (RAG), hybrid search using vector databases (e.g., Pinecone, Elasticsearch), multi-agent AI systems with tool calls, and prompt engineering is required.
• Experience designing and implementing robust evaluation frameworks for LLM-based systems, including rubric-based scoring, LLM Judges, or using tools like MLflow, alongside monitoring performance and drift.
• Familiarity with large-scale data processing platforms and tools (e.g., Databricks, Apache Spark).
• Practical experience with libraries and frameworks like LangChain or LlamaIndex for building LLM-powered applications.
• Demonstrated ability to lead complex technical projects and foster the growth of other engineers.

RESPONSIBILITIES:

• Design, build, and operate scalable, low-latency backend services and APIs that serve Generative AI features, from retrieval-augmented generation (RAG) pipelines to complex agentic systems.
• Own the end-to-end lifecycle of AI-powered applications, including system design, development, deployment (CI/CD), monitoring, and optimization in production environments like Databricks and Azure Kubernetes Service (AKS).
• Continuously improve retrieval and generation quality through techniques like retrieval optimization (tuning k-values, chunk sizes), using re-rankers, advanced chunking strategies, and prompt engineering for hallucination reduction.
• Engineer solutions that seamlessly combine LLMs with the proprietary knowledge of repositories, external APIs, and real-time data streams to create powerful copilots and research assistants.
• Collaborate with data science and engineering teams to establish and implement best practices for LLMOps, including automated evaluation using frameworks like LLM Judges or MLflow, AI observability, and system monitoring.
• Systematically evaluate and apply advanced prompt engineering methods (e.g., Chain-of-Thought, ReAct) and other model interaction techniques to optimize the performance and safety of proprietary and open-source LLMs.
• Provide technical leadership to junior engineers through rigorous code reviews, mentorship, and design discussions, elevating the team's engineering standards.
• Partner closely with product and business stakeholders to translate user needs into technical requirements, define priorities, and shape the future of the AI product offerings.

• US and EU projects based on advanced technologies.
• Competitive compensation based on skills and experience.
• Regular performance appraisals to support your growth.
• Comprehensive private medical insurance.
• Christmas Bonus in the amount of 50% of the monthly payment.
