ENVIRONMENT:

A dynamic Software Consultancy seeks the coding expertise of a Senior Ruby on Rails Developer for a hands-on role where you will design and deliver end-to-end features on a cross-border banking platform. In this role, you'll work across the entire stack—building intuitive Frontends, enhancing and scaling backend services, and ensuring that the platform remains secure, performant, and reliable. While you'll focus heavily on hands-on coding, you'll also weigh in on design decisions to ensure future scalability and maintainability. The ideal candidate will have 8+ years of hands-on Software Development, including a proven track record working across the stack (Frontend and Backend) on production-grade applications. Your tech toolset should include React, JavaScript/TypeScript, GraphQL/RESTful APIs & PostgreSQL. You must be willing to overlap work hours until 12:00-13:00 EST (Negotiable).

DUTIES:

Build End-to-End features -

• Implement new product features across the stack—designing and developing both client-facing UI (in React, TypeScript/JavaScript) and Backend services (in Ruby on Rails with PostgreSQL).

Improve Frontend experiences -

• Optimize the Frontend for performance, accessibility, and responsiveness.
• Contribute to a polished, intuitive user experience by refining UI components and user flows.

Enhance Backend services -

• Develop robust APIs and integrations that maintain strict data consistency and perform under high concurrency.
• Ensure fault-tolerance, scalability, and security throughout our services.

Maintain Quality & Reliability -

• Write Unit, Integration, and End-to-end Tests.
• Setup and refine monitoring, logging, and alerting to keep our systems stable and responsive in production.

Collaborate with Cross-Functional Teams -

• Work closely with Product Managers, Designers, and fellow Developers to translate requirements into actionable technical solutions.
• Provide input on trade-offs, timelines, and feasibility.

Participate in technical discussions -

• Contribute to architectural reviews and propose incremental improvements.
• While you'll focus heavily on hands-on coding, you'll also weigh in on design decisions to ensure future scalability and maintainability.

Mentor and learn -

• Lead by example in code reviews, offering constructive feedback and guidance.
• Support the growth of less-experienced Developers while continuing to hone your own skills.

Stay current and innovative -

• Keep an eye on industry trends, experiment with tools and frameworks, and introduce incremental improvements that enhance development velocity and product quality.

REQUIREMENTS:

• Experience: 8+ years of hands-on Software Development, including a proven track record working across the stack (Frontend and Backend) on production-grade applications.
• Frontend Skills: Proficiency with modern Frontend frameworks (e.g., React) and JavaScript/TypeScript. Strong grasp of responsive design, accessibility, and performance optimization.
• Backend Proficiency: Experience building and operating distributed systems, GraphQL/RESTful APIs, and data-intensive applications.
• Comfort with relational databases (PostgreSQL) and understanding of concurrency, fault-tolerance, and data consistency.
• Ability to work remotely with your own equipment.
• Willingness to overlap work hours until 12:00-13:0
