Job description

Marketer has hit the mark with its AI-driven marketing platform for e‑commerce players. Following an exceptional launch across Europe, the Nordic scaleup has now entered the US market, and is therefore seeking local talent to strengthen the commercial team.

About the company

Marketer delivers an AI-powered, all‑in‑one marketing suite for e‑commerce businesses that simplifies and streamlines all digital marketing needs in ways that were previously impossible. The SAAS platform is integrated with Shopify, the world’s largest e‑commerce ecosystem, making it incredibly easy to adopt. The result is that e‑commerce businesses can now accomplish tasks that used to require specialized agencies, independently, within minutes. Naturally, this has a significant impact on the ROAS.

A byproduct is a detailed, real‑time overview of marketing and sales activities—something customers highly value. This stands in stark contrast to the Excel‑sheet handovers stores are accustomed to from traditional marketing agencies.

Marketer was established in 2022 by the founders of Marketer Technologies, now one of Europe’s largest proptech companies. After two years of technical development, the commercial operations kicked off in full force in 2024. The company is now experiencing explosive growth and already boasts a solid ARR that is increasing by several hundred thousand per month.

The cap table includes Marketer Technologies, alongside the greatest chess player of all time, Magnus Carlsen, Johan Brand from Kahoot, and a handful of other prominent figures in tech and finance.

Who we're looking for

You write clean, scalable React code in your sleep and take ownership like your name’s on the cap table. This isn’t just about building UI — it’s about crafting high‑performance, business‑critical user experiences for thousands of real eCommerce companies.

What you'll do

• Build and scale key front‑end features for Marketer's core web platform using TypeScript, React, and modern component patterns.
• Turn high‑fidelity Figma designs into pixel‑perfect, fast, and responsive UIs.
• Own advanced front‑end logic: state management, performance optimization, accessibility (WCAG), and everything in between.
• Integrate cleanly with RESTful and GraphQL APIs.
• Write reliable, well‑tested code with Jest, React Testing Library, and Playwright.
• Work side‑by‑side with product, design, and backend teams to ship fast and iterate faster.
• Take part in architecture discussions — you’re not just a ticket‑taker.

You're a great fit if you…

• Have strong TypeScript skills, including advanced typing (generics, inference, utility types).
• Are highly experienced in React, with deep knowledge of hooks, context, and scalable state management.
• Have at least 5 years of FE experience.
• Have at least 3 years of hands‑on experience with Next.js.
• Are comfortable working with Tailwind CSS for scalable and maintainable UI systems.
• Have experience working with CMS platforms such as Sanity (or similar headless CMS tools).
• Care about clean, scalable code and improving the codebase with every commit.
• Have built and worked within modern CI/CD workflows.
• Are comfortable switching between complex front‑end logic and pixel‑perfect CSS.
• Understand and care about accessibility — building for all users, not just the defaults.

This is not for you if you…

• You need rigid specs or tickets to get started.
• You avoid writing tests.
• You’re uncomfortable in a fast‑moving, high‑ownership team where quality and speed both matter.
• You’re looking for a routine 9–5. This is startup territory — high reward, high expectations.

Who you'll work with you

• Directly with Marketer's founding team, including the CEO.
• Collaborating closely with product designers, backend engineers, and mobile developers.
• A team that’s taken Marketer from $0 to $3M+ ARR in just 3 months — and we’re only getting started.

What you'll get

• Competitive Salary (based on experience) + potential stock options.
• Full equipment setup (MacBook, monitor, and anything else you need).
• Freedom to work remotely or from our Oslo HQ.
• A product‑led culture where your work ships fast and is used by thousands of Shopify brands.
• The chance to shape the product and codebase, not just maintain it.
