Full Job Description
ABOUT US Ruby Labs is a leading tech company that creates and operates innovative consumer products. We offer a diverse range of opportunities across the health, education, and entertainment industries. Our innovative teams are driving the future of consumer-led products, and we're always looking for passionate individuals to join us. Learn more about our story at: https://rubylabs.com/about-us/ ABOUT THE ROLE We're building and scaling a profitable D2C product used by hundreds of thousands of customers globally, processing large volumes of traffic and revenue every month. The product is well beyond MVP: it's battle-tested in production, monetizing at scale, and now entering a phase of rapid growth and expansion. We're doubling down on building a world-class engineering organization to support continued scale. We're looking for a Senior Full-Stack Engineer who can take meaningful ownership of complex areas of the product — and run with them. You won't be waiting for tickets or specs. You'll be expected to drive technical decisions in your area, push back on scope when it's wrong, flag unrealistic timelines early, and own product areas end-to-end with minimal supervision. This is not about maintaining a legacy system. It's about scaling real products used by real users — fast, and shipping in days, not weeks. If you're looking for a comfortable 9–5 role, this won't be the right fit. But if you're excited by ownership, accountability, and building high-quality systems under real-world pressure, read on. KEY RESPONSIBILITIES - Own complex product areas end-to-end — from architecture decisions through implementation, deployment, and post-launch iteration. - Drive technical direction in your area without waiting for tickets or detailed specs. - Provide engineering input directly to Product and leadership — push back on scope, flag risks, propose better solutions. - Take responsibility for the reliability, performance, and scalability of your area in a high-traffic envi
