Key Responsibilities

We are hiring Lead AI engineering role for someone who wants to bring deep software architecture and cloud infrastructure experience into AI/ML and GenAI systems. You will design, build, and operate the platform that our production-grade AI/ML, GenAI, Simulation, sematic layer, knowledge base, RAG, OCR.

Expect to spend the majority of your time building: writing production code, architecting and provisioning cloud infrastructure, and debugging systems in production for GenAI — with technical mentorship and architecture reviews as a smaller part of the role, not the main one.

ML & GenAI Platform Engineering

• Design and build scalable ML/GenAI pipelines (batch & real-time)
• Build and operate model-serving infrastructure, profile and optimize inference latency in edge compute
• Build RAG pipelines, LLM orchestration frameworks, and multi-agent/agentic workflow systems
• Build and maintain vector database and embedding pipeline infrastructure
• Build and maintain company knowledge base
• Build and unify key components of AI Platform, e.g. API gateway, guardrail, auth enabled MCP/tool-calling, tracing
• Deep dive into best practice for context management, harness, agent memory management

MLOps & Reliability

• Implement model versioning, monitoring, and retraining pipelines
• Build integrated data flywheel for eval and model improvement
• Setup best practice for data versioning
• Ensure reproducibility and reliability of ML systems end-to-end

Software Architecture

• Make architecture decisions for the platform, then build the core pieces yourself as reference implementations others build on
• Implement shared libraries and reusable building blocks (self-service deployment, GenAI services/APIs) rather than just specifying them
• Review code and architecture for the rest of the team

Cloud & Infrastructure

• Architect and build the cloud infrastructure (AWS, Azure, or GCP) the platform runs on — compute, networking, IAM, storage, managed Kubernetes
• Write and maintain infrastructure-as-code (Terraform or equivalent)
• Build and maintain end-to-end CI/CD pipelines for ML/GenAI workloads
• Own cost and performance optimization of cloud and LLM infrastructure

Collaboration

• Work directly with data scientists and AI Engineers to productionize models
• Partner with the Head of AI on technical roadmap and cloud/vendor decisions
• Evaluate emerging GenAI tools and frameworks hands-on before recommending adoption

Key Requirements

• Degree qualifications at the Bachelor's, Master's, or PhD level in Computer Science, Mathematics, or a closely related field.
• With minimum 10 to 12 years in software engineering or GenAI Platform Engineering.
• Must-have: deep, hands-on experience with at least one major cloud platform (AWS, Azure, or GCP) — experience in building and operating a production infrastructure
• Strong Python experience and hands-on expertise in: Docker, Kubernetes, Terraform/IaC, CI/CD pipelines, MLflow.
• Hands-on experience building and running Agentic AI applications/harnesses in production e.g. tool-calling agents, multi-agent orchestration, agent evaluation/observability.
• Ongoing commitment to training and professional development in AI/ML, GenAI, and the aviation domain — Cargo Handling, Ground Handling, Ground Freight, and Food Solutions.
• Experience in aviation, logistics, or supply chain industries.
• Familiarity with production Optimization (Operations Research), Computer Vision, or Simulation systems, OCR.
