About the Role:

Our core system is a Ruby on Rails application running on Google Cloud Platform (GCP), with BigQuery as the data warehouse behind it.

It handles the full customer lifecycle: lead and deal management, contracting and onboarding, consumer unit registration with the DISCOs, energy allocation, invoicing, collections, and cancellation. Around it sits a growing set of services - automated scraping of distribution company portals, document workflows, APIs with service providers and our ERP system (ODOO), and internal reporting.

Role & responsibilities:

- System Ownership: Take full responsibility for the health, maintenance, and optimization of the Phase 1.0 Ruby on Rails application.
- New Features Buildup: Ship features and improvements end to end - mainly around the billing, contract management, energy allocation, reporting, data model, business logic, background jobs, and UI.
- Feature Upgrades & Maintenance: Architect and deploy necessary feature upgrades, security patches, and performance improvements to the legacy system without disrupting active enterprise users.
- Cross-Team Collaboration: Work synchronously and asynchronously with the Phase 1.5 development team to align on API structures, data migrations, and system handoffs.
- Database & Cloud Management: Optimize complex queries and manage our managed PostgreSQL instances (Cloud SQL) and BigQuery data warehouses on Google Cloud Platform (GCP).
- Reporting: Work with BigQuery as the analytical layer - maintain the views and pipelines that feed our reporting and finance workflows.
- Front-End Modernization: Maintain and refine the user interface using Hotwire (Turbo/Stimulus) and TailwindCSS, keeping the application highly responsive and lightweight.
- Documentation: Write clear documentation and keep the system understandable to people other than you.

What we're looking for:

- Deep Ruby on Rails Expertise:



7+ years of production experience building, maintaining, and scaling full-stack applications in Ruby on Rails.
- Database Proficiency: Solid experience with PostgreSQL, including optimizing complex queries in Managed Cloud SQL environments.

Experience with BigQuery is highly preferred.

- Cloud Infrastructure: Proven experience navigating and deploying applications within Google Cloud Platform (GCP).
- Testing: Solid testing discipline (RSpec or Minitest) and experience with Git-based workflows and CI/CD.
- Modern Rails Front-End: Hands-on experience building dynamic interfaces using Hotwire (Turbo and Stimulus) without relying on heavy Single Page Application (SPA) frameworks.
- Styling: Strong proficiency in TailwindCSS.
- Background Jobs: Extensive experience configuring and managing background processing with Sidekiq and Redis.
- Communication: Excellent written and spoken English. You must be able to document your work clearly and communicate complex technical tradeoffs to a distributed global team.
- Autonomy: Proven ability to thrive in a 100% remote environment, managing your own time and prioritising effectively with minimal micromanagement.

Nice to have:

- Experience with web scraping / browser automation and resilient integrations against unstable external portals.
- Background in fintech, billing, invoicing, subscriptions or any domain with heavy financial reconciliation.
- Experience with the energy sector, utilities or metering data.
- Exposure to Odoo, ERP integrations or accounting data models.
- Comfort using AI-assisted development tools as part of a normal workflow.

Why Join Us?:

- Impact: Build software that directly accelerates the transition to sustainable, distributed energy.
- Stability & Growth: Join a profitable, high-traction business that is heavily investing in its technology teams.
- Autonomy: Work 100% remotely with flexible hours, trusted to own your domain.
