Quant SME - Contract - 5 days per week on site in London - £ per day via Umbrella
This role is 5 days per week on site in London
£ per day via umbrella
Experience:
Exposure to Thomson Reuters, Bloomberg applications, Excel Add-ins, etc.
Hands-on experience in computing multi-asset portfolio statistics
Building/maintaining a Python library (not app work): packaging, versioning, releasing a package that downstream services depend on. This is the core of the job.
Time-series data engineering with pandas at scale (multi-index frames, frequency alignment, currency/tenor handling). pandas is the entire data plane here.
Snowflake/data-warehouse experience: writing SQL against curated vendor tables, EAV vs wide-table schemas. This is how all market data actually arrives - not via Bloomberg/Reuters terminals directly.
Vendor data onboarding (FactSet, EODHD, Macrobond, Albourne-style feeds) - mapping vendor schemas into a canonical model.
Skills:
Strong Python 3.11+: dataclasses, type hints, pydantic v2 not just "knowledge of Python." Set a clear bar (mid/senior).
Parser/AST/interpreter design this is a DSL. Comfort with tokenizing, expression trees, immutable AST nodes, and a parse validate execute pipeline is the single most repo-specific skill.
pandas + numpy/scipy proficiency (statsmodels, scikit-learn for the analytics extra).
GitLab CI/CD specifically (pipelines, not just "use gitlab"): the repo runs lint test build publish stages.
Testing discipline: pytest, property-based testing (Hypothesis), fixture/regression suites. Given ~230 test files and hermetic catalog-regression, this is essential I'd make it a first-class skill, not implied.
Linting/quality tooling: ruff, type checking (pyright/basedpyright).
YAML-driven configuration/mapping design.
Optimization libraries: scipy (SLSQP), optionally cvxpy/numba for the weight-optimization functions.
API/contract discipline: designing stable interfaces since a separate service consumes this library.
Knowledge of how to use gitlab
Knowledge of Software architecture principles
Team player, supporting Front End, middle-tier teams with API implementations
AI-assisted/agent-driven development the repo is heavily to...
