Technical Lead – Ruby on Rails & React

We are onboarding a Senior Technical Leader with strong enterprise experience to elevate engineering quality across our React and Ruby on Rails ecosystem. This is not a single-project role—you will function as a Quality Architect, driving consistency, scalability, and best practices across multiple codebases while mentoring developers and setting technical direction.

In addition to architectural oversight, you will remain hands-on, contributing to the design, development, testing, and deployment of modern, scalable web applications within a fully remote team.

• Lead by example through hands-on development using Ruby on Rails (latest version) and modern frontend practices

• Mentor and guide developers through code reviews, architecture discussions, and best-practice adoption

• Design, build, and maintain scalable web applications in a Dockerized environment

• Ensure high code quality through comprehensive test coverage using Capybara, Selenium, and Minitest

• Collaborate with cross-functional teams in a monthly sprint cadence, managed via Notion

• Oversee version control, branching strategies, and pull-request workflows on GitHub

• Contribute to system architecture, performance tuning, and security best practices

• Leverage cloud services such as AWS (S3, SQS, CloudWatch)

• Troubleshoot, debug, refactor, and modernize existing systems

• Support integrations with third-party services, including OpenAI where applicable
