AI/ML Engineer

Join our AI Teams and help us build production-grade AI solutions that directly support and scale our global sales organization within the airline industry!

You will play a critical role in increasing sales efficiency, response quality, and speed-to-market by embedding AI into sales and pre-sales processes. Your work will focus on automating and augmenting sales-related workflows such as RFP/RFI processing, proposal generation, customer-specific solution descriptions, pricing inputs, and knowledge retrieval.

This role combines hands-on technical leadership with the opportunity to shape and grow a distributed AI engineering team. You will act as a technical lead for sales-focused AI initiatives and, over time, take responsibility for guiding and mentoring a team of AI engineers.

Your responsibilities will include

• Architect and implement scalable AI/ML solutions on Azure (preferred) or GCP, leveraging services such as Azure Databricks, Azure ML Studio, Data Lake Storage, Event Hubs and Functions (or GCP equivalents)
• Design and build AI solutions for sales use cases such as:
• Automated RFP/RFI ingestion, classification, and response generation
• Intelligent document understanding (PDFs, Word, Excel, presentations)
• Knowledge retrieval across product documentation, contracts, and past proposals
• Sales assistant capabilities powered by LLMs
• Develop and deploy LLM-based systems using prompt engineering, fine-tuning, and retrieval-augmented generation (RAG)
• Integrate ML and GenAI solutions with enterprise platforms such as CRM systems, document repositories, collaboration tools, and workflow engines
• Drive the evolution of successful PoCs into robust MVPs ready for adoption by sales and pre-sales teams
• Implement MLOps practices including CI/CD for ML, infrastructure-as-code, model versioning, and automated retraining and deployment pipelines
• Provide technical guidance, code reviews, and architectural support to AI engineers, with a growing responsibility for mentoring and leading a distributed team
• Stay ahead of emerging AI trends, tools, and frameworks to continuously push innovation boundaries

Must-Have Qualifications

• Bachelor’s, Master’s or PhD in Computer Science, Engineering, Mathematics or related quantitative field
• 3+ years of experience in ML engineering or AI solution development, ideally with production deployments supporting enterprise or business-facing use cases
• Familiarity with Azure data & AI services (e.g.: Azure Databricks, Azure ML Studio, Data Factory, Data Lake, Event Hubs, Functions) or GCP equivalents
• Strong experience with GenAI systems, including LLMs, prompt engineering, fine-tuning, MCP and retrieval-augmented generation (RAG)
• Familiarity with agentic or multi-agent system concepts and architectures
• Strong programming skills in Python
• Self-starter mindset with a passion for innovation and experimentation
• Excellent communication skills in English; ability to present complex architectures to stakeholders

Preferred Skills

• Hands-on experience with document AI, NLP, semantic search, or knowledge graph solutions
• Experience with CI/CD pipelines for ML (Azure DevOps, GitHub Actions) and infrastructure-as-code (Terraform or ARM templates)
• Exposure to MLOps practices and tools (e.g. CI/CD, model versioning, MLflow, Kubeflow)
• Hands-on Spark/Databricks expertise
• Experience building PoCs and MVPs in AI/ML contexts
• Familiarity with data engineering fundamentals for preparing and curating datasets for experimentation and model training
• Demonstrated experience acting as a technical lead, owning architecture decisions and guiding other engineers
