Requirements
  • Strong production Python skills.
  • In-depth knowledge of factor risk models and portfolio attribution, including cross-sectional regression, covariance estimation and shrinkage, and defensible back-testing.
  • Knowledge of point-in-time discipline, look-ahead and survivorship bias, and reconstructing what was knowable on a given date.
  • Experience with statistical modelling and optimisation using statsmodels and cvxpy; PyTorch is useful.
  • Experience working with datasets in pandas and Parquet/Arrow, plus an analytical engine such as DuckDB.
Responsibilities
  • Develop statistical models of stock price movements and estimate the performance of thematic trends.
  • Construct and back-test factor risk models, decomposing stock returns into thematic and traditional risk factors.
  • Design and validate signal-generation and portfolio-attribution methodologies in collaboration with the economics team.
  • Make research reproducible so that published output can be re-run exactly, including after backfills and restatements.
  • Work with the pipelines team to take modelling decisions into daily production.
Desired Qualifications
  • A quantitative research background in academia or industry.
  • Experience with index construction and classification taxonomies.
  • Experience working with model-derived inputs and understanding that natural-language-processing-generated exposures carry measurement error and revise over time.
  • Experience with task orchestration using Dagster or Airflow and S3-based data flows.
  • AWS fluency and CI/CD discipline.

Theia Insights grabs $8M to map the global economy with AI.

Theia Insights grabs $8M to map the global economy with AI. The funding will support expansion into new asset classes, starting with private markets, alongside further development of research and engineering capabilities and the growth of the company's global commercial presence. Cambridge-based deeptech company Theia Insights has raised $8 million in Series A funding, led by MiddleGame Ventures, with participation from Further Ventures and Unusual Ventures. The round brings the company's total funding to $14.5 million to date. Theia is addressing a structural limitation in financial markets: the lack of a real-time, accurate representation of the global economy. Most financial institutions rely on static classification systems that assign companies a single industry label, despite businesses increasingly operating across multiple sectors that evolve over time. This fragmentation limits the effectiveness of both human analysis and AI systems, which depend on accurate and consistent data structures to generate meaningful insights. Founded by Dr Ye Tian, Isami Ito, and Dr James Thorne, Theia brings together expertise in AI, financial markets, and enterprise software to build what it describes as a dynamic, AI-driven map of the global economy. Its proprietary technology processes a wide range of corporate data (including regulatory filings, earnings transcripts, and financial disclosures), to create a continuously updated, multidimensional view of company activity. Instead of a single industry label, companies are represented through evolving exposure across multiple sectors and themes. This approach underpins Theia's suite of products, which includes tools for dynamic industry classification, thematic analysis, and translating investment ideas into data-driven company universes. Together, these systems enable financial institutions to better understand structural trends, support portfolio construction, and improve decision-making across research, analytics, and trading workflows. We must first see the economy clearly, not in fragments but as an interconnected whole. Theia exists to map the unmapped, to make visible the structure of the global economy, said Dr. Ye Tian, Founder and CEO of Theia Insights. The company's technology is already used by global index providers, asset managers, hedge funds, and banks, supporting a range of applications from research to portfolio construction. As financial markets increasingly adopt AI-driven workflows, Theia positions its platform as a foundational data layer that enables both humans and machines to reason consistently about economic activity. The funding will be used to expand Theia's platform into new asset classes, beginning with private markets, as well as to further develop its research and engineering capabilities and scale its global commercial presence.
