Job Description:

Senior Software Engineer – Python / PySpark (Mainframe Modernization)

Team Objective

The team is responsible for modernizing a core mainframe-based financial application by rewriting it onto a distributed platform.
This application serves as the front door for financial data, acting as the system of record (SLR) and feeding downstream general ledger systems.
The platform is embedded within Corporate Accounting and plays a critical role in enterprise financial reporting and controls.

This candidate will serve as a technical SME, guiding a team that is actively upskilling from mainframe technologies into modern Python-based platforms.
While this is not a people-lead role, the position requires strong mentorship, technical guidance, and exceptional communication skills.
The engineer will work closely with Product Owners, Lines of Business, and Operations teams, and must be comfortable presenting technical concepts to both technical and non-technical audiences.

Strong expertise in Python, with production experience using PySpark
Backend experience with FastAPI and/or Flask
Frontend experience with React and/or Angular
Experience with SQL Server and/or Exadata
Hands-on experience with Kafka or other streaming platforms
Experience working in Agile / Scrum delivery models
Strong communication, presentation, and stakeholder engagement skills
Ability to guide and mentor other engineers as a senior technical contributor

Cloud Platforms: AWS (Glue, Lambda, Redshift, S3, CloudWatch)

Data Integration & Migration: Hadoop ecosystems, Kafka, real-time streaming, data lakes
Data Modeling: dimensional models, structured and unstructured data processing
CI/CD & Automation: GitHub Actions, Azure DevOps, Jenkins, Git, Autosys, Airflow

Required Skills:

CI/CD: (GitHub Actions / Azure DevOps), Kubernates

Industry Background (Preferred):

Familiarity with financial data flows, general ledger concepts, and accounting terminology is a plus, though strong technical expertise is the primary requirement

Ideal Candidate Profile:

Senior-level individual contributor with strong backend engineering depth
Comfortable serving as an SME and mentor without formal people-management responsibilities
