Tech Lead, Ruby on Rails

The Mission

The mission of the Tech Lead is to drive the technical excellence, operational stability, and architectural integrity of our Ruby on Rails and React-based payment systems. You will own the end-to-end lifecycle of our applications, from the efficiency of our CI/CD pipelines to the resilience of our AWS infrastructure. Your goal is to serve as a high-impact individual contributor while elevating the entire team through mentorship and the implementation of engineering best practices.

12-Month Outcomes

• Architecture Evolution: Successfully lead the design and implementation of at least two major architectural enhancements that improve system scalability or decrease technical debt within the payment ecosystem.
• Operational Excellence: Reduce deployment friction and lead-time by optimizing our Jenkins-based CI/CD system and Terraform configurations.
• Performance Optimization: Improve application response times and database efficiency (MySQL/MongoDB), ensuring the platform remains performant during peak high-volume cycles.
• Technical Mentorship: Establish a "culture of quality" by standardizing code review processes and helping at least two mid-to-senior engineers level up their architectural thinking.
• Security & Compliance: Partner with the Security team to ensure 100% compliance with fintech standards, specifically focusing on our Stripe integration and data handling.

Key Responsibilities

• Architect & Build: Spend approximately 60% of your time as a "player-coach," delivering high-quality Ruby on Rails and React code while overseeing overall system design.
• DevOps & SRE Ownership: Lead the team’s "you build it, you run it" philosophy by managing AWS infrastructure via Terraform and participating in a rotating on-call schedule.
• SME for Payments: Serve as the primary Subject Matter Expert for our Stripe integration, ensuring seamless processing for $1.6B+ in transactions.
• CI/CD Leadership: Own and optimize the automated deployment pipeline (Jenkins/Git), ensuring code moves from development to production safely and frequently.
• Cross-Functional Partnership: Collaborate closely with Product Managers and Security Leads to translate business requirements into robust technical specifications.
• Standard Setting: Define and enforce engineering standards for testing, documentation, and performance monitoring across the stack.

Required Skills

• Ruby on Rails Mastery: Deep expertise in building, scaling, and maintaining complex Rails applications.
• Full-Stack Fluency: Strong proficiency in React for front-end development and a solid understanding of how it interfaces with Rails APIs.
• Cloud Infrastructure: Proven experience managing AWS environments using "Infrastructure as Code" (Terraform).
• Data Persistence: Expertise in both relational (MySQL) and non-relational (MongoDB) database design, optimization, and scaling.
• Fintech Knowledge: Practical experience with payment gateways (specifically Stripe) and handling large-scale financial data.
• Technical Leadership: Demonstrated ability to mentor engineers, perform rigorous code reviews, and lead technical decision-making without a "command and control" approach.

Leveraging GenAI in This Role

We encourage our leads to work smarter. In this role, you can leverage GenAI tools to:

• Accelerate Documentation: Rapidly generate baseline technical documentation or READMEs for new architectural patterns.
• Optimize Code Reviews: Use AI-driven analysis to catch edge cases in complex Ruby logic or identify potential security vulnerabilities in Stripe integrations.
• Terraform Scripting: Use LLMs to generate boilerplate Terraform modules or troubleshoot complex Jenkins pipeline configurations.
• Unit Test Generation: Speed up the creation of comprehensive test suites for legacy codebases.

Nice to Have Skills

• Experience migrating legacy monolithic architectures to modular or microservices-based structures.
• Background in SRE (Site Reliability Engineering) practices, specifically around SLO/SLI definition.
• Active participation in the Open Source community or a history of technical blogging/speaking.
