Interview Process: Video & Onsite
We're seeking an experienced Python Developer to lead the automation and orchestration of complex data workflows. The ideal candidate will have hands-on experience designing robust, fault-tolerant, and auditable pipelines across on-prem Oracle systems, integrating with job schedulers like RunMyJobs, and modernizing legacy processes using Apache Airflow.
You will play a critical role in replacing legacy Perl/PLSQL scheduling logic with modern, Python-based DAG orchestration while ensuring traceability, data quality, and recoverability.
Key Responsibilities:
" Develop, deploy, and maintain Python-based automation scripts to orchestrate jobs across Oracle 19c on-prem systems.
" Design and implement Airflow DAGs to manage complex interdependent ETL workflows.
" Migrate existing job logic from Perl, RunMyJob, and PL/SQL-based scheduling into modular, observable Airflow DAGs.
" Build custom Airflow operators/sensors for integration with Oracle, REST APIs, file drops (SFTP/FTP), and external triggers.
" Implement robust error handling, alerting and retry mechanisms across job pipelines.
" Collaborate with DBAs and application teams to understand job dependencies, critical paths, and data lineage.
" Establish job execution logs, audit trails, and SLA monitoring dashboards.
" Participate in code reviews, documentation, and onboarding new jobs into the orchestrator.
Required Skills and Experience:
" 5+ years of Python development experience, with strong understanding of system/process automation.
" 2+ years of Apache Airflow building production DAGs.
" Solid understanding of Oracle 19c database, SQL tuning, and PL/SQL concepts.
" Experience orchestrating jobs that move large volumes of data across enterprise systems.
" Familiarity with job schedulers (RunMyJob, Autosys, etc.) and how to replace/abstract them using orchestration tools.
" Strong debugging skills across logs, databases, and filesystem for failed jobs or partial runs.
" Experience building REST API integrations, SFTP/file movement logic, and parameter-driven automation.
Bonus / Preferred Experience:
" Prior experience modernizing legacy data workflows from Perl or PL/SQL stored procs.
" Hands-on knowledge of Git/Bitbucket, Jenkins, CI/CD pipelines for code-controlled job rollouts.
" Familiarity with financial data models (e.g., holdings, transactions, NAVs, tax lots).
" Basic understanding of data governance, audit, and operational risk in financial systems.
