Job Description :

Senior Software Engineer – Python (Computation & Rules Engine)

Role Overview

We are building a high-performance, deterministic computation engine in Python that executes complex, versioned rules and calculations over large, structured datasets . This engine powers financial availability, eligibility, and risk calculations and must be correct, explainable, auditable, and fast . Build a high-performance, deterministic Python computation engine that executes complex rules over large datasets with absolute correctness and explainability.

This is a pure backend engineering role focused on algorithms, data processing, system design, and performance —not UI and not business analysis.

Core Engineering Responsibilities

• Design and implement pure computation modules in Python with :
• Deterministic outputs
• Idempotent execution
• Strong guarantees around precision and reproducibility
• Build a rule execution framework supporting :
• Declarative rule definitions
• Versioning and effective dating
• Rule dependency graphs
• Short-circuiting and prioritization
• Implement high-volume data pipelines to :
• Load, validate, normalize, and transform large datasets
• Execute calculations efficiently in batch and incremental modes
• Optimize performance across :
• CPU usage
• Memory footprint
• IO patterns
• Parallel execution (where appropriate)
• Design explainability artifacts :
• Structured calculation traces
• Rule evaluation graphs
• Intermediate state snapshots
• Implement numerically safe calculations :
• Decimal arithmetic
• Explicit rounding strategies
• Stable aggregation and reconciliation logic
• Build robust testing infrastructure :
• Unit tests for individual rules
• Property-based tests for invariants
• Golden dataset regression tests
• Design APIs and internal interfaces for :
• Batch execution
• Streaming / delta-based recalculation
• Downstream consumers (services, workflows)
