Backend Engineer

• Migrate and re-architect legacy Perl batch jobs and crontab pipelines into modern Python-based services
• Design and implement orchestration using Prefect or Airflow, including alerting, observability dashboards, and safe job re-run capabilities
• Manage the data layer for file ingestion: landing raw scheme files to S3, parsing/transforming them, and persisting to PostgreSQL or RDS for reconciliation
• Process and reconcile payment scheme files from card schemes and acquirers
• Write technical documentation and establish best practices across the team

Senior Backend Developer, File Processing

• Dual-Track Maintenance: Support and extend the existing Perl-based payment gateway debugging production issues and adding features while the migration is ongoing.
• Modernization: Design, develop, and maintain modern server-side components in Python, ensuring high performance and scalability.
• Integrations: Integrate third-party APIs and external payment services into both legacy and modern platform layers.
• Agile Collaboration: Maintain clean and strong English communication to effectively collaborate with multiple stakeholders across departments working in agile sprints.
• Product Thinking: Go beyond the "what" and "how" of the code bring a product-focused mindset to understand the business logic and user impact of what you build.
• Engineering Standards: Participate in code reviews, uphold high code quality standards, and contribute to a culture of continuous improvement.
• Infrastructure: Work closely with DevOps on CI/CD pipelines, containerization, and cloud deployments.

Senior Backend Engineer, Python – Core Gateway

• System Implementation: Support the re-architecture of legacy Perl batch jobs into modern, maintainable Python services.
• Operational Reliability: Assist in implementing workflow orchestration (Prefect/Airflow) to ensure safe job re-runs and system stability.
• Observability: Help instrument our services with logging and alerting (Grafana/CloudWatch) so we can monitor systems without direct production access.
• Data Transformation: Work on data ingestion pipelines, moving raw data to S3 and transforming it into relational database records.
• Collaboration: Participate in agile sprints and maintain clear English communication with the team and stakeholders.
