The Role

As a Senior Software Engineer (Python / SQL) , you will take ownership of stabilizing and modernizing a portfolio of critical applications and scheduled jobs that power business operations. This is a hands-on role where you’ll dive deep into existing Python / SQL (and occasional PHP) codebases, uncover hidden dependencies, and bring structure and reliability to legacy systems.

Your mission will be to transform fragile scripts into well-documented, testable, and resilient workflows , while leading the migration of legacy schedulers and Airflow instances into a managed Airflow environment . This role is ideal for someone who enjoys reverse-engineering complex systems, creating clarity out of chaos, and driving high-impact modernization efforts.

What You’ll Do

• Map legacy systems : read Python / SQL (occasional PHP), document data flows, dependencies, and failure modes.
• Modernize & de-risk : refactor scripts, add tests, improve retries / idempotency, kill redundant jobs.
• Migrate to managed Airflow (AWS) : plan DAG moves, secrets, CI / CD, and observability.
• Improve reliability / visibility : alerting, on-call-friendly logs, backfill strategies, fewer false alarms.
• Partner with stakeholders : capture the “why,” translate to requirements, communicate trade-offs / timelines.
• Raise the bar : code reviews, mentoring, security / documentation culture.
