👀 The Migration team at Shine

As part of our newly formed Migration Team - comprising two engineers and an assigned PM - you will drive Portfolio Unification by migrating users off legacy products and onto Shine unified platform, covering identity, core data, billing, and historical document archives. Your work is vital for Revenue Protection, ensuring end-users transition safely off EOL products before deprecation. Additionally, you will build scalable processes to ensure M&A Readiness for future acquisitions. You will collaborate closely with the IAM and Billing platform teams, as well as stream-aligned teams in Product Accounting and Invoicing.

📋 Your role as an Engineering Manager - Migration

As the technical lead of this new squad, you will act as a player-coach, managing the growth of two engineers while defining the technical architecture for cross-cloud queue workers and ETL pipelines. In partnership with the PM, you will architect a phased migration strategy—beginning with legal consent and auth setup, progressing through core entity synchronization (customers, products), and concluding with the asynchronous migration of historical documents.

A key part of your mission is to bridge the feature gap between legacy systems and Shine. You will collaborate with the Product team to ensure our data models handle these discrepancies gracefully. You will also manage billing complexity by coordinating the transition from legacy billing systems to Shine's unified setup, ensuring zero double-billing. We're looking for someone who finds satisfaction in meticulous, large-scale execution — seeing things through to the very end, shutting systems down cleanly, and protecting every byte of user data along the way.

Your responsibilities will include:

• Stakeholder Alignment: Coordinate with legacy infrastructure and product teams to secure data extracts without impacting production environments.

• Platform Integration: Partner with platform-aligned teams to define and execute pragmatic, frictionless migration paths for our users.

• Team Leadership: Run team rituals and ensure high predictability against strict regulatory and End-of-Life (EOL) deadlines.

• People Development: Lead 1-on-1s and manage performance for a squad of two engineers, supporting their professional growth.

• Technical Sparring: Actively review queue/worker architectures, database schemas, binary-to-PDF conversion scripts, and API payloads.
