Senior Software Engineer - Backend / Rules

Category: Software Development/ Engineering

Main location: United States, District of Columbia, Washington

Position ID:J0626-1063

Employment Type: Full Time

Position Description:

We're building an AI-assisted platform that helps our client audit federal financial data,
and we need a senior backend engineer to build its decision-making core: a rules
engine that takes the facts pulled from client supplied data and applies complex eligibility
and subsidy rules to determine whether a payment was correct. The defining requirement is
trustworthiness - the same inputs must always produce the same result, and every decision must
be fully explainable and auditable, because real federal dollars and audit findings ride on it.
This position is located in our Fairfax, VA, Knoxville, TN, Lebanon, VA, Belton, TX or Lafayette, LA office; however, a hybrid working model is acceptable.

Your future duties and responsibilities:

- Design and build the rules engine: given a set of facts about a case, apply the governing
rules to reach a decision, with the guarantee that identical inputs always yield identical,
auditable outputs.
- Build the framework that lets the rules be authored and versioned, including logic that
applies the right rules for each specific program (the programs have different rules across
many sub-programs).
- Build a thorough automated test suite - reproducibility and traceability are first-class
requirements, not afterthoughts.
- Support rolling out updated rule versions and parameters in future audit cycles.

Required qualifications to be successful in this role:

- Bachelor's degree in Computer Science, Engineering, or a related field.
- 7+ years of professional software engineering experience.
- Strong deterministic backend development.
- Demonstrated experience with rules-engine / decision-logic design and versioned-artifact
discipline.
- Strong automated-testing discipline.
- Must be a US person and able to obtain the suitability/clearance required for an AWS
GovCloud environment.
Desired qualifications/non-essential skills required:
- Experience in regulated domains where reproducibility and auditability are mandatory
(finance, healthcare, government benefits).
- Familiarity with policy-as-code or configuration-driven rule systems.
- Exposure to benefits-program eligibility/subsidy logic.
