Superformula
We’re looking for a senior engineer to build a migration service that moves customers from a legacy payments platform into a core platform.
The source system is a legacy PHP application with a SQL database. The target is a set of REST APIs. The work involves understanding the existing data model, mapping it to the new platform, and building a reliable migration service that can be run repeatedly for different partners.
Migration sizes range from a handful of records to hundreds of thousands.
Requirements
What You’ll Be Working On
-
Reading data directly from a legacy SQL schema
-
Mapping legacy entities to current API models
-
Building migration workflows that can start, stop, resume, and retry
-
Tracking migration progress and failures
-
Handling large migrations that may run for hours or days
-
Working through cases where source and target systems don’t map cleanly
-
Integrating with payment, merchant, user, subscription, and token-related data
Some payment data may require access to encrypted values within the source environment before being sent to the destination platform.
Tech Stack
-
TypeScript / Node.js
-
SQL
-
REST APIs
-
Docker
-
Kubernetes
What We’re Looking For
-
Strong TypeScript and Node.js experience
-
Data migration and ETL experience
-
Seasoned Experience with Docker and Kubernetes in production
-
Comfortable working directly with relational databases
-
Experience building backend services and long-running background processes
-
Good systems design instincts around reliability, observability, and recovery
-
Able to work through incomplete requirements and messy legacy systems without needing everything specified up front
Bonus Points
-
Payments or fintech experience
-
Experience with PHP (in order to reverse engineer any undocumented legacy API interactions)
Highlights
This is a good fit for someone who enjoys understanding existing systems, figuring out where the edge cases are, and building software that operators can trust to move critical data correctly.
