About the Role
We are seeking a Senior Software Engineer to support the modernization of a mission-critical, mainframe-based financial application onto a distributed, cloud-native platform. This role is primarily backend-focused, with a strong emphasis on Python and PySpark, and includes occasional frontend contributions using React and Angular.
You will join a Scrum-based delivery team embedded within Corporate Accounting, working on a system that serves as the enterprise system of record for financial data and feeds downstream general ledger platforms. This is a high-impact role that directly supports enterprise financial reporting, controls, and compliance.
While this is an individual contributor role (no formal people management), you will act as a technical subject matter expert (SME), mentoring engineers transitioning from legacy mainframe technologies to modern Python-based systems.
Responsibilities
  • Design, develop, and modernize backend services to replace legacy mainframe functionality on a distributed platform
  • Build and maintain data ingestion, validation, and transformation pipelines using Python and PySpark
  • Develop and support RESTful APIs using FastAPI and/or Flask
  • Ensure data accuracy, reliability, and integrity for financial data feeding enterprise general ledger systems
  • Collaborate within an Agile/Scrum team alongside Product Owners, Lines of Business stakeholders, and Operations teams
  • Serve as a Python SME, providing technical guidance and mentorship to engineers transitioning from mainframe technologies
  • Contribute to frontend development using React and Angular as required
  • Participate in technical design discussions, architecture reviews, and code reviews
  • Support CI/CD pipelines and cloud-native deployments using containerized platforms
  • Communicate effectively through technical documentation, stakeholder discussions, and presentations to both technical and non-technical audiences
Required Qualifications
  • 7+ years of professional software engineering experience
  • Strong expertise in Python, including production experience with PySpark
  • Backend development experience with FastAPI and/or Flask
  • Frontend development experience with React and/or Angular
  • Experience working with SQL Server and/or Exadata
  • Hands-on experience with Kafka or other streaming platforms
  • Experience working in Agile / Scrum delivery environments
  • Strong communication and stakeholder engagement skills
  • Proven ability to guide and mentor engineers as a senior technical contributor
Preferred Qualifications
  • Experience in financial institutions or enterprise accounting environments
  • Familiarity with financial data flows, general ledger concepts, and accounting terminology
Nice-to-Have Skills
  • Agentic AI frameworks: LangGraph, LangChain, A2A
  • Programming Languages: Java, Scala, SQL, HiveQL
  • Big Data Technologies: Hadoop, Spark, HDFS, Hive, Cloudera, Hortonworks
  • Cloud Platforms: AWS (Glue, Lambda, Redshift, S3, CloudWatch)
  • ETL / ELT Tools: AWS Glue, PySpark, Databricks
  • Data Integration & Migration: Kafka, data lakes, real-time streaming architectures
  • Data Modeling: Dimensional models; structured and unstructured data processing
  • CI/CD & Automation: GitHub Actions, Azure DevOps, Jenkins, Git, Autosys, Airflow
  • Containerization & Orchestration: Kubernetes
Ideal Candidate Profile
  • Senior-level individual contributor with deep backend engineering expertise
  • Comfortable acting as a technical SME and mentor without direct people-management responsibilities
  • Confident communicator capable of explaining complex technical systems clearly
  • Collaborative, adaptable, and effective in cross-functional enterprise environments
