Job description

The role

We’re looking for a Ruby on Rails Developer to support a project focused on integrating data pipelines and reporting modules for the Renewable Fuels Standard (RFS). You’ll work on building a pipeline to automatically retrieve data from SQL databases and a reporting module for the EMTS system, ensuring reliable, scalable, and well-tested solutions.


What you’ll do

  • Design, implement, and maintain data pipelines to retrieve large volumes of data from SQL databases

  • Process, transform, and export data to formats like CSV

  • Integrate with external systems using XML/REST APIs, handling validation, transactions, and error scenarios

  • Configure and manage connections to multiple SQL databases, including multi-tenant setups

  • Work with VPNs, authentication, and connection management (host, port, user, password)

  • Collaborate with product, QA, and domain experts to understand client specifications and test solutions in sandbox environments

  • Contribute to improving code quality, maintainability, and system documentation


Requirements

  • Strong experience with Ruby on Rails, especially in large monolithic repositories

  • Proven experience designing and implementing data pipelines

  • Solid knowledge of SQL databases, different schemas, table structures, and multi-tenant configurations

  • Hands-on experience with VPNs, authentication, and connection handling

  • Experience with XML/REST integrations, including validation and transaction handling

  • Ability to quickly understand client specifications and test in sandbox environments


Nice to have

  • Experience in projects related to environmental regulations, energy, or finance

  • Familiarity with reporting systems like EMTS

Disclaimer: We do not expect deep domain knowledge of the Renewable Fuels Standard. We provide strong domain support to help you understand the regulatory context.


Please note that this is a 1-month contract with the possibility of extension.
