IMC is seeking an experienced operational leader to join our growing US Equities desk in New York as Chief Operating Officer. As we build and scale this business, the Equities COO will serve as the right hand to the Desk Head, ensuring the desk operates efficiently, communicates effectively, and stays focused on both short- and long-term goals. This is a high-visibility, high-impact role that sits at the intersection of trading, strategy, operations, and people — acting as a force multiplier for the Desk Head and ensuring the desk’s most critical priorities move forward with speed and clarity.

This role focuses on driving strategic execution, managing the desk’s operating rhythm, and strengthening team culture and cross-functional coordination. You will apply structured problem-solving to complex business challenges, lead high-priority initiatives, and represent the desk across internal and external stakeholders. The position provides meaningful ownership and broad organizational impact from day one. Compensation is competitive and aligned with individual contribution.

Your Core Responsibilities:

• Serve as a trusted partner to the Desk Head, driving the desk’s highest-priority initiatives and ensuring alignment across trading, technology, risk, and business support teams.
• Apply structured problem-solving to evaluate opportunities, assess risks, and drive data-informed solutions in close collaboration with desk and firm leadership.
• Lead or contribute to high-priority projects such as product expansions, business planning cycles, and operational improvement programs.
• Own goal tracking and milestones, ensuring communication processes are completed as goals are achieved or priorities shift.
• Build and apply substantive knowledge of market structure, competitive dynamics, and regulatory developments to shape the desk’s strategic priorities.
• Own the operating rhythm of the desk — meetings, action items, goal tracking, and cross-functional workstreams — and continuously identify opportunities to improve efficiency, communication, and scalability.
• Represent desk leadership within and outside of the team through high-quality communication.
• Oversee onboarding for new hires and transfers by coordinating logistics and delivering a smooth and consistent experience.
• Actively monitor and assess team culture and dynamics, serving as a sounding board to desk leadership on organizational needs.
• Work with stakeholders and the recruitment team to coordinate and improve recruitment pipelines.

Your Skills and Experience:

• 5+ years of experience in roles requiring strong stakeholder management, cross-functional execution, and structured problem-solving, such as management consulting at a top-tier firm.
• Corporate strategy or COO experience at a financial services or technology firm is a strong plus.
• Exceptionally high emotional intelligence: self-aware, adaptable, and effective at building trust and navigating complex interpersonal dynamics across all levels of the organization.
• Demonstrated ability to take ownership and deliver results in unstructured and ambiguous environments.
• Outstanding written and verbal communication skills, including the ability to craft compelling narratives and tailor messaging to different audiences.
• Strong STEM background strongly preferred (Physics, Math, Econometrics, or equivalent).
• Equities or broader financial markets experience is a plus but not a prerequisite — intellectual curiosity and the ability to ramp up quickly matter more.

Please note that immigration sponsorship is not offered for this specific opening.

This is a unique opportunity to solve problems at the intersection of advanced machine learning and trading, where your contributions will shape the future of IMC’s technology and trading capabilities.

Your Core Responsibilities: 

• Develop large-scale distributed training pipelines to manage datasets and complex models
• Build and optimize low-latency inference pipelines, ensuring models deliver real-time predictions in production systems
• Develop libraries to improve the performance of machine learning frameworks
• Maximize performance in training and inference using GPU hardware and acceleration libraries
• Design scalable model frameworks capable of handling high-volume trading data and delivering real-time, high-accuracy predictions
• Collaborate with quantitative researchers to automate ML experiments, hyperparameter tuning, and model retraining
• Partner with HPC specialists to optimize workflows, improve training speed, and reduce costs

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.
