Senior Full-Stack Engineer (Next.js / Node)

Largify Solutions builds production software for businesses in the UAE, USA and UK — custom platforms, SaaS products, booking systems and operational tools. As a Senior Full-Stack Engineer you will own features end-to-end across our Custom Software Development, SaaS Product Development and Web Development engagements.

You will work closely with design and delivery leads, turn ambiguous client requirements into shipped product, and raise the quality bar for TypeScript, data modeling and UI reliability. This is a hands-on role: you write code daily, review peers, and help juniors land safe, maintainable changes.

Typical work includes App Router Next.js apps, authenticated dashboards, Supabase/Postgres backends, payment and messaging integrations, and performance-sensitive public marketing sites.

• Design, implement and ship Next.js (App Router) features with clean TypeScript
• Model Postgres/Supabase schemas, RLS-aware access and reliable API boundaries
• Build auth, billing, notifications and third-party integrations
• Own UI quality: accessibility, loading states, error handling and Core Web Vitals
• Partner with PMs and designers to clarify scope and avoid rework
• Review pull requests and mentor mid-level engineers on patterns that scale
• Document decisions so client and internal teams can operate the product after launch

• 4+ years shipping production web applications
• Strong React/Next.js and Node.js experience in TypeScript
• Solid SQL and relational modeling (Postgres preferred)
• Comfortable owning delivery in an async remote team with clear written updates
• Experience with auth, file uploads, and at least one payments or messaging integration
• Portfolio or references that show shipped client or SaaS work, not only demos

• Remote-first delivery with overlap for UAE / USA / UK clients
• Real client products across software, AI and growth marketing
• Clear ownership, written async culture, and senior mentorship
• Path to lead tracks as you grow delivery quality and client trust
• Compensation and benefits are shared privately during the interview process
