## Description

As a Senior Full-Stack Engineer, you'll be working with our engineering team and a global product squad and will be instrumental in building highly scalable, robust, and innovative features across our entire ecosystem.

(Note: We primarily use Ruby on Rails and React.js. If you're not deeply familiar with Ruby, no worries-we care much more about your core engineering patterns and full-stack architecture skills, and provide dedicated up-skilling!)

Your key focus areas will be:

 * End-to-End Feature Delivery: Guiding your squad to design, scope, and deploy high-impact, full-stack features that solve real customer needs.
 * System Reliability & Health: Proactively identifying SaaS application pain points, scaling system architecture, and ensuring absolute security and stability.
 * Engineering Mentorship: Fostering a high-performance culture by coaching junior and intermediate engineers to level up their skills.

This will include:

 * Full-Stack Implementation: Collaborating with your engineering squad to design, implement, and deploy scalable features across our Rails and React ecosystem.
 * Cross-Functional Translation: Partnering closely with a global team of designers, product managers, and UX specialists to turn abstract business needs into elegant technical solutions.
 * Technical Leadership & Review: Reviewing code, providing constructive feedback, mentoring team members, and actively driving knowledge sharing across squads.
 * System Optimization: Navigating a complex SaaS ecosystem to identify performance bottlenecks and proactively implementing mitigation strategies or process improvements.
 * Quality & Automated Testing: Writing robust automated tests for production code and taking absolute ownership of application reliability and root-cause analysis.
 * Continuous Stack Up-skilling: Actively participating in our dedicated training programs to smoothly transition into and master our core technology stack.
