Full job description

Who Are We?

Breeze is a digital-first travel connectivity brand powered by eSIM Go, one of the world's most advanced eSIM platforms. Our mission is to become the most trusted, frictionless global connectivity solution for regular travellers — setting a new benchmark for customer experience across the connectivity industry.

We operate at the intersection of travel, technology, and consumer education, partnering with globally recognised brands including the Lufthansa Group, Booking.com, and Western Union. We are building Breeze on two non-negotiable foundations: a digital-first product philosophy and an unwavering commitment to the customer.

The Role

We are looking for a Full Stack Web Developer to join our growing tech team. You will be embedded in the day-to-day delivery of our web products, owning the front-end experience across our Shopify-powered eCommerce estate, building and maintaining backend services, and enabling our marketing and acquisition functions through robust technical integrations. This is a hands-on role with real ownership and direct impact on customer experience.

What You'll Be Doing

Building, maintaining, and optimising our Shopify-based eCommerce storefronts across multiple partner brands.
Developing responsive, performant front-end interfaces with TypeScript and a modern component framework (our storefront currently uses Vue).
Designing and maintaining RESTful APIs and backend services in TypeScript/Node.js.
Integrating marketing and analytics tooling, including Klaviyo, PostHog, Meta, and Google acquisition channels.
Collaborating with the product and commercial teams to translate business requirements into scalable technical solutions.
Driving code reviews and upholding high standards for code quality, security, and performance.
Contributing to architecture decisions and the ongoing migration from Shopify toward a custom backend stack.
Working within an agile framework: sprint planning, stand-ups, retrospectives, and iterative delivery.

What You'll Need

5+ years of professional web development experience across multiple products or teams.
Strong expertise in JavaScript/TypeScript, HTML, and CSS, with solid experience in at least one modern component framework (React, Vue, Angular, Svelte, or similar). We hire for JS/TS fundamentals, not a single framework; our storefront currently uses Vue.
Solid backend experience in TypeScript/Node.js (Cloudflare Workers, Fly.io, or similar).
Relational data modelling experience (PostgreSQL or similar).
Familiarity with analytics and product telemetry tools (PostHog, GA4, or equivalent).
Hands-on, daily experience with AI-assisted coding tools (Cursor, Claude Code, Codex, GitHub Copilot, or similar), and the judgement to review their output critically.
Experience in a startup or scale-up environment where pace and pragmatism matter.
Strong written and verbal English communication skills.
The ability to work independently, remotely, and take end-to-end ownership of features.

Nice to Have

Shopify experience, including theme customisation, Liquid, and the Shopify API (our storefront is heavily built on it).
Cloudflare (Workers, KV, Queues) and Fly.io serverless deployment.
GraphQL experience (our own APIs are REST-first; useful for the Shopify Admin API).
Marketing automation (Klaviyo) and acquisition channels (Meta, Google).
Experience with agentic AI chatbot integration.
eSIM, telecom, or travel-tech domain experience.

The Interview Process

Our process is straightforward and respects your time. Expect an initial conversation with our Tech Lead, followed by a technical assessment focused on real-world problems we face, and a final conversation with senior leadership. We are not interested in abstract puzzles. We want to see how you think and build.
