About The Position

We’re building and scaling a profitable D2C platform 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’ve recently launched a second product in the same ecosystem and are doubling down on building a world-class engineering organization to support continued scale.
We’re looking for a Senior Next.js Full-Stack Engineer who can combine hands-on technical excellence with strong ownership. You’ll be responsible not just for shipping code, but for shaping architecture, improving reliability, raising engineering standards in a high-paced environment.
This role is not about maintaining a legacy system. It’s about scaling real products used by real users — fast.
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.

• Experience with CI/CD pipelines, Docker, and cloud infrastructure (preferably AWS, Cloudflare).
• Solid understanding of PostgreSQL and Redis, including performance tuning and schema design.
• Experience with A/B testing frameworks and using analytics to drive product decisions.
• Familiarity with CMS (preferably Payload)
• Demonstrated ability to mentor other engineers and elevate team performance.
• Clear communication style — able to explain complex topics clearly and concisely.
• A proactive mindset — you spot issues before they become problems and take ownership.
• Comfortable making technical decisions and defending them with logic and data.
• Experience leading teams or projects.
