ABOUT THE ROLE & TEAM

We are seeking a Lead Data Engineer with expertise in AI agent systems and mathematical problem-solving frameworks to build and scale intelligent data platforms. This role focuses on designing systems where multiple AI agents collaborate to solve complex tasks, including analytical reasoning, optimization, and mathematical computation. You will lead the development of infrastructure that integrates LLMs, symbolic solvers, and data pipelines into cohesive, production-ready systems.

WHAT YOU WILL DO

Lead the design and scaling of intelligent data platforms where multiple AI agents collaborate to solve complex analytical and mathematical tasks.
Design and implement multi-agent architectures where agents coordinate, communicate and execute workflows (planning, memory, tool usage).
Build orchestration layers and guardrails, ensuring robustness, traceability, and observability of agent decisions.
Integrate mathematical engines (symbolic and numerical solvers) and external tools/APIs into LLM-driven workflows.
Engineer scalable batch and real-time data pipelines and data models supporting agent memory and retrieval (vector databases/RAG).
Establish LLMOps/MLOps practices for deployment, monitoring, evaluation and testing (including mathematical correctness).
Optimize performance and cost of LLM and compute-heavy workloads; drive CI/CD and operational excellence.
Provide technical leadership: set best practices, mentor engineers, and translate business problems into AI-driven solutions.

Qualifications:

WHO YOU ARE

6+ years in data engineering and/or distributed systems with hands-on delivery of production platforms.

Strong Python and SQL skills; experience designing and operating data models, data quality controls and observability.
Experience with distributed data processing and streaming (e.g., Spark, Kafka) and cloud platforms (AWS, Azure, or GCP).
Experience building LLM-based systems; familiarity with agent frameworks (orchestration, tool usage, memory) and RAG/vector databases.
Strong mathematical foundation (linear algebra, probability/statistics, optimization) and ability to translate business problems into formal models.
Experience with scientific computing and/or solver integration (e.g., NumPy/SciPy/SymPy, optimization libraries, symbolic/numerical engines).
Understanding of security best practices and governance for data/AI platforms (identity and access management, secrets management, auditability).
Proven system design capability and technical leadership (architecture decisions, standards, mentoring).
Aviation/OCC domain exposure is a strong advantage.
