Senior Fullstack Engineer

About Timeleft

Timeleft is a social app that brings strangers together for IRL events. Every week, 150,000 people across 200+ cities open the app, discover who they're matched with, chat with their group, and head to a restaurant to meet for the first time.

Behind every one of those connections is the product you'll build. Restaurant partnerships that make those dinners possible. Event logistics that ensure the right groups land at the right tables. Customer support workflows that solve problems before they escalate. Right now, it's our internal operating system. Soon, it becomes the platform our restaurant partners log into every day to track their events and manage their relationship with us.

That's what you'll be building.

Role Overview

We're hiring a Senior Fullstack Engineer who works as a product engineer first. You'll own features end-to-end on our Next.js + PostgreSQL/Supabase stack — shaping what to build, how it should feel, and how it ships. We expect opinions on product, sharp prototypes, and judgment about scope.

The product itself is changing. Today it's the internal operating system for managing the whole digital side of the Timeleft business. Over the coming months it becomes a SaaS: we're opening it to our restaurant partners so they can sign in, follow their hosted events, and self-serve. You'll be a core engineer on that pivot: thinking in tenants, plans, and partner-facing UX, not just admin tooling.

You'll use AI-assisted development daily — Claude Code is our preferred tool — and you'll spend real time with the people using what you build, internal teams today and restaurant partners tomorrow. We don't want prompt-and-paste engineers; we want engineers who use AI as leverage, listen carefully to feedback, and own every line that lands in production. The bar is ownership, not output volume.

Key Responsibilities

End-to-end product delivery

• Own features from problem framing to production: data model, API surface, UX/UI, testing, monitoring
• Make product calls in flight — what to scope down, what to polish, what to cut — without needing a PM or designer for every decision
• Prototype to resolve ambiguity instead of writing specs about it

SaaS pivot and partner-facing portal

• Help shape and ship the transformation of our internal backoffice into a partner-facing SaaS
• Build
