• Work closely with ICT project integrators and independent consultants to ensure successful configuration, startup, commissioning quality of ICT services to support critical data centre applications.
• Work closely technical peer reviewers and the design team to drive issue resolution of contractor’s design.
• Work closely with the AirTrunk Technology team to provide valuable project execution feedback and share industry knowledge to enhance AirTrunk ICT standards for data centre builds and infrastructure.
• Provide technical support to the AirTrunk Commissioning Team if design driven issues are identified during testing and commissioning.
• Occasionally conduct site visits to ensure installation ICT services are installed in accordance with approved design documentation.
• Occasionally travel to AirTrunk Data Centres in APME to conduct site, design and opportunity reviews.
• Occasionally attend and provide expert advice on risks and opportunities through equipment Factory Acceptance Testing (FAT) a proof-of-concept testing.
• Occasionally assist AirTrunk operational teams with complex ICT systems integrations, and issue troubleshooting. 

Requirements

• Demonstrated 10+ years in ICT engineering roles, with 5+ years in senior/lead engineering or ICT architectural positions (data center experience preferred).
• Bachelor’s degree in Information Technology, Computer Engineering, or related discipline (Master’s preferred)
• Proven experience delivering large-scale ICT programs and enterprise systems.
• Incredibly flexible and adaptable to a dynamic fast-paced, collaborative environment.
• Willing to make decisions and be accountable for them.
• Excel at communication with the ability to deliver effective presentations on data center design to customers, peers, and management.

At IMC, we believe technology is the foundation of our competitive edge — and machine learning is increasingly central to how we trade. Over the past few years, we've been steadily building our machine learning capabilities: developing infrastructure, growing our in-house GPU cluster, deploying models into production, and partnering closely with quant researchers and traders to generate real impact. Now we’re expanding the team, scaling our systems, and accelerating the application of deep learning in our research and execution workflows.  We're looking for a Principal Machine Learning Engineer to help shape the next phase of our platform — influencing architecture, driving best practices, and solving high-leverage problems. You’ll work alongside researchers and technologists to design the systems that power experimentation, training, and deployment of ML models — and help set the direction for how machine learning is done at IMC as we scale. If you’ve built ML infrastructure at scale elsewhere and are looking for a role where your ideas will genuinely help shape our firm’s future — we’d love to hear from you.

Your Core Responsibilities: 

• Design and build end-to-end infrastructure for training, evaluation, and productionization of ML models, working closely with our HPC engineers who manage our on-prem compute cluster
• Influence foundational choices around data access, compute orchestration, experiment tracking, model versioning, and deployment pipelines
• Partner with quant researchers to accelerate iteration cycles, tighten feedback loops, and bring models from prototype to live trading
• Work with researchers to adapt and deploy modern architectures — transformers, state-space models, temporal convolutions, graph neural networks — to noisy, high-frequency financial data. Explore techniques like self-supervised pretraining, representation learning, and cross-sectional modelling where they offer genuine edge
• Shape our approach to reproducibility, continual learning, and production monitoring across a petabyte-scale data environment
• Define standards that create consistency across teams and geographies; mentor engineers and influence technical culture beyond your immediate work
• Keep pace with developments in deep learning research and ML infrastructure; bring ideas from academia and industry into how we work — whether that's new architectures, training techniques, or tooling

Your Skills and Experience: 

• 8+ years of experience building ML platforms or infrastructure at a leading tech company, research lab, or quantitative firm
• A track record of designing and owning large-scale training and inference systems — not just contributing, but architecting
• Deep proficiency in Python, with strong experience in either CUDA or C++
• Hands-on expertise with modern deep learning frameworks (PyTorch, TensorFlow, or JAX) and practical experience implementing architectures like transformers, attention mechanisms, or sequence models
• Strong foundation in deep learning fundamentals: optimization, regularization, loss design, and the trade-offs that matter when training at scale
• Experience with distributed training at scale (Horovod, NCCL) and GPU optimization (cuDNN, TensorRT)
• History of deploying models to production with strong observability, reproducibility, and monitoring practices
• Comfort working across the ML stack from data pipelines to training infrastructure to serving systems

Why This Role: 

• Build, don't inherit — You'll make foundational technology choices in a platform that's still being defined, not maintain someone else's legacy.
• Real investment, real backing — This is a strategic priority with resources behind it, not a side experiment.
• Direct impact on trading — Your infrastructure will power models that make real trading decisions in competitive global markets.
• Global scope — Work with teams across New York, Chicago, Amsterdam, London, Sydney, Hong Kong and beyond; define practices that can scale worldwide.
• Ideas over titles — IMC's culture values clarity, rigor, and collaboration. The best ideas win, regardless of where they come from.
• Tight coupling with research — You won't be building in isolation. Researchers and engineers work side-by-side, iterating together.
