The Challenge

Are you energized by bridging the gap between cutting-edge AI research and battle-tested production systems?

We are seeking a senior-level Applied AI / Machine Learning Software Engineer to spearhead the engineering foundation for next-generation quantitative investment workflows. Operating at the dynamic intersection of AI/ML, quantitative finance, and high-scale systems architecture, you will take innovative research concepts out of the lab and turn them into resilient, high-throughput engines powering live trading and portfolio decision-making.

What You Will Do

• From Hypothesis to Production: Conceptualize, prototype, and rigorously evaluate state-of-the-art AI/ML models, engineering them into scalable, low-latency production applications.

• Architect Core Infrastructure: Design and implement modular libraries, testing frameworks, and scalable infrastructure that streamline the quantitative research and deployment lifecycle.

• Power Global Investment Strategies: Embed AI solutions directly into high-impact workflows across Equities, Fixed Income, and Multi-Asset strategies.

• Drive Technical Excellence: Provide hands-on technical leadership, set code quality standards, and advocate for best-in-class software engineering and system reliability.

• Cross-Disciplinary Collaboration: Partner closely with quantitative researchers, portfolio managers, and global engineering teams to solve complex, non-linear market challenges.

• Industry Engagement: Represent the organization at top-tier industry conferences and contribute to open-source initiatives where appropriate.

What You Bring

• Academic Foundation: Master’s or PhD in Computer Science, Machine Learning, Mathematics, Statistics, Physics, Quantitative Finance, or a related quantitative discipline (or equivalent demonstrably deep industry experience).

• Proven Track Record: 5+ years of software engineering experience building robust, production-grade applications within finance, quantitative technology, or related data-intensive domains.

• Core Engineering Chops: Exceptional programming skills in Python, C++, Java, or modern object-oriented/functional languages, backed by solid computer science fundamentals (data structures, algorithms, concurrency).

• Applied AI/ML Expertise: Practical experience designing, training, evaluating, and deploying modern machine learning or deep learning systems.

• Market Familiarity: Hands-on experience developing software supporting quantitative investment workflows and a solid grasp of asset classes (Equities, Fixed Income, or Multi-Asset).

• Engineering Rigor: Deep commitment to clean architecture, automated testing, continuous integration, scalability, and maintainability.

Bonus Points

• Demonstrated success taking novel ML/AI models from pure experimentation into high-availability production environments.

• Hands-on experience with financial time-series data, massive structured datasets, and portfolio analytics.

• Exposure to distributed computing, cloud architectures, or high-performance computing (HPC).

• A public footprint in the engineering/research community (open-source contributions, technical blog posts, or conference papers).
