CTO / Quant Engineer
AI Summary
The CTO / Quant Engineer owns the end-to-end ML lifecycle for an AI system serving the private equity industry, designing production pipelines, taming messy data, and fine-tuning LLMs and vision models.
About this role
The Project
We are building an AI system that is the backbone for the private equity industry.
The Role
Quantitative background (MSc/PhD in computational finance, statistics, applied math, physics, or ML). Fluent in probabilistic programming (JAX, NumPyro, PyMC). Hands-on experience building data pipelines on real-world messy inputs. Has fine-tuned large models for domain-specific tasks using frameworks like Unsloth or HuggingFace. Thinks in distributions, not point estimates. Uncomfortable when a system returns a number without a credible interval.
What You Will Do
Build Production Pipelines: Take ownership of the end-to-end ML lifecycle. You will transition models from local Jupyter notebooks to scalable, production-ready systems.
Tame Messy Data: Architect data ingestion pipelines capable of handling noisy, real-world inputs—including scanned PDFs, inconsistent reporting formats, and missing data points.
Leverage Foundational Models: Fine-tune LLMs and vision models for domain-specific financial tasks.
Optimize for Efficiency: Apply techniques like LoRA, quantization, and efficient training loops using frameworks like Unsloth and HuggingFace to make large-scale AI practical and cost-effective.
Apply Advanced Mathematics: Utilize Bayesian inference and probabilistic programming to model uncertainty in private market valuations.
What We Are Looking For
Foundations
Quantitative background (MSc/PhD in computational finance, statistics, applied math, physics, or ML)
Experience with probabilistic programming and Bayesian inference (JAX, NumPyro, PyMC)
Experience
Engineering Chops: Proven experience building production pipelines. You know firsthand the critical difference between a proof-of-concept demo and a resilient production system.
Applied AI/GenAI: Hands-on experience working with foundational models. You have successfully fine-tuned LLMs.
Resourceful Tooling: Deep familiarity with the modern AI stack (HuggingFace, Unsloth, PyTorch, etc.) and a knack for maximizing model performance on a startup budget.
Bonus Points
Comfortable with agent-based modeling and economic simulation
Familiarity with financial concepts (NAV, IRR, fund structures) — PE experience a plus but not required
