Be part of shaping what gets built, from idea to launch, at the intersection of AI and B2B SaaS.

At Proposales, we’re transforming how hotels sell and manage Groups, Meetings & Events. We’re building a modern product platform for an industry that still relies heavily on legacy systems and manual processes, helping hotels move from inquiry to booking and delivery through beautifully designed software, automation and AI.

We’re now taking the next step, expanding Proposales beyond proposals into booking, workflows and AI powered operations. As a Product Engineer, you’ll work at the intersection of product, design and engineering, turning ambitious ideas into simple, polished experiences used by hotels around the world. You’ll have real ownership, ship quickly and help shape both what we build and how we build it. This role is based in our Stockholm office, fully on-site.

Your mission:

• Take product initiatives from idea to shipped: scope, build, iterate, launch

• Use AI agents as a genuine force multiplier, not just for boilerplate, but for real product development

• Translate business problems into product decisions without needing someone to bridge the gap for you

• Work closely with leadership and the product team to identify what actually matters to build next

• Keep quality high; know when to trust what an agent produces and when to push back on it

What we believe in:

We're serverless first, hosted on Vercel with a monorepo built using Next.js and TypeScript.

We use AI where it clearly helps, in product and in internal tooling, and we care about reliability, safe handling of data, and keeping automation and human judgment in the right balance.

We value judgment over credentials, ownership over process, and shipping over speccing.

Some of the technologies you would be working with:

• JavaScript / TypeScript

• React, Next.js

• Node.js

• PostgreSQL

• Vercel / Vercel AI SDK

• MCP

• LLM based tooling (Claude, Cursor, or similar)

A bit about you:

• You think like a founder: you understand why something is being built, not just how

• You're comfortable going from blank page to production without a detailed brief

• You use AI tools daily and know how to get production quality output from them, not just prototypes

• You have enough engineering depth to catch what agents miss and make sound architectural calls

• You've shipped things: real things, that real people use

• You value clarity and collaboration over rigid processes

• Fluent in English (written and spoken)

• You live in Stockholm and thrive in an office first team culture
