Job Description

Responsibilities

Core Architecture & Type System • Design and implement robust UML-based architectures and Python protocols. • Build strongly typed systems using typing.Protocol, Abstract Base Classes (ABCs), and Python’s data model. • Ensure 100% mypy strict-mode compliance with no ignored errors. • Implement correct total ordering logic using custom dunder methods. • Validate interfaces via runtime isinstance checks.

Memory Management & Lifecycle Control • Prevent memory leaks in long-running Python processes. • Optimize memory usage using garbage collection strategies, weakref, and slots. • Perform memory profiling using tools like tracemalloc or objgraph. • Ensure zero unintended object growth over time.

Scientific Computation & Performance Optimization • Develop high-performance simulation and interpolation logic using NumPy and SciPy. • Implement lazy rebuild strategies for computational efficiency. • Use vectorized operations exclusively (no Python loops over datasets). • Profile execution using cProfile and ensure sub-10ms execution time for datasets under 10k rows.

Descriptor Algorithms & Numerical Accuracy • Implement mathematically accurate descriptor algorithms as per defined logic specifications. • Perform numerical integration using stateless, functional programming patterns. • Build thread-safe implementations using frozen dataclasses. • Create robust unit tests covering edge cases with hand-verified golden datasets.

Mentorship & Code Quality Governance • Review and mentor contributions from data scientists and other engineers. • Enforce architectural constraints, performance standards, and best practices. • Maintain CI/CD pipelines and static analysis tooling (Ruff, Black). • Ensure zero PEP8 violations and keep cyclomatic complexity under defined limits. • Provide complete docstrings for all public APIs.

Data Structures & Serialization • Design efficient, immutable data structures for data ingestion and state management. • Optimize Pandas DataFrame generation without unnecessary memory duplication. • Ensure correct data types (e.g., float64, datetime64) and handle defined boundary conditions.

Requirements

Technical Skills • Expert-level Python with deep knowledge of the Python data model • Strong experience with: • NumPy, SciPy, Pandas • Static typing (mypy, typing.Protocol) • Memory profiling and optimization • Performance profiling and benchmarking • Experience with immutable data structures and functional programming concepts • Strong unit testing and CI/CD experience

Quality & Process • Proven ability to write production-grade, highly optimized code • Strong understanding of software architecture and system design • Experience enforcing coding standards in collaborative environments • High attention to mathematical correctness and edge-case handling
