We're past MVP, battle-tested in production, and now entering a phase of rapid growth and expansion. We're looking for a Middle Full-Stack Engineer who ships fast and independently across the stack — someone hungry to grow into senior responsibilities. You'll take ownership of features assigned to you, execute strongly on your own, communicate blockers early, and lean on the team for architectural guidance on more complex decisions.

If you're looking for a comfortable 9–5 role, this won't be the right fit. But if you're excited by responsibility, growth, and building high-quality systems in a high-pace environment, read on. KEY RESPONSIBILITIES - Build, ship, and iterate on core product features across the stack. - Take ownership of features assigned to you — from implementation through production rollout and iteration. - Implement responsive, accessible UIs using TypeScript, TailwindCSS, and established design systems. - Work with backend services and APIs, integrating frontend logic with scalable systems. - Participate actively in code reviews and contribute to maintaining high engineering standards. - Debug, optimize, and improve production systems in a high-traffic environment. - Communicate blockers, risks, and progress early and clearly. - W
