Frontend / Integrations Engineer

We are now looking for a talented Frontend / Integrations Engineer to join our Product Development Team and build the next generation of integrations between Relewise and platforms like Shopify and headless stacks such as Medusa. If you’re passionate about front-end development, care about visual polish and user experience, and love working with the latest technologies (from React/Vue to Node.js), this role is for you!

As a Frontend / Integrations Engineer on our team, you will report to and work closely with our CPO to bring integration ideas to life. You’ll work with our open-source UI Components library and demo shop (built with Vue) to ensure our solution not only works seamlessly across platforms but also looks and feels great for end-users. This is a collaborative, autonomous role in a cross-functional environment – you’ll have plenty of freedom to innovate, and we expect you to proactively shape solutions and solve problems. Sound interesting? Read on!

You will get to

• Build & maintain integrations between Relewise’s personalization platform and third-party commerce, CMS, and marketing systems (e.g. Shopify, Medusa, commercetools, Uniform), enabling clients to plug our AI-driven recommendations and search into their existing tech stack.
  
  
• Develop front-end components and connectors using our open-source Relewise UI Components (Web Components) and contribute to our Vue.js demo shop. You’ll create and refine widgets, plugins, and reference implementations that showcase how Relewise can be embedded seamlessly into various storefronts.
  
  
• Ensure polished UI/UX for all integration projects – you take pride in delivering visually appealing, responsive, and user-friendly interfaces. While you don’t need to be a designer, you’ll work to make sure the final implementation has a high level of visual polish and provides a smooth user experience.
  
  
• Work across different tech stacks depending on the integration. One day you might be writing a React plugin, another day a small Node.js service or a Vue component. You’ll embrace variety and quickly pick up new frameworks or tools as needed to get the job done.
  
  
• Collaborate closely with the team – you’ll partner with backend developers, and client-facing teams to design integration solutions. You’ll also work hand-in-hand with our CPO to align on priorities and ensure we build the right features.
  
  
• Leverage AI tools in development – as part of an AI-first engineering culture, you’ll use tools like GitHub Copilot, ChatGPT/Claude, and others to accelerate coding, testing, and troubleshooting. We encourage innovative, AI-assisted approaches to boost productivity and creativity in our projects.

We expect you to have

• Strong front-end development experience: You have a solid grasp of JavaScript/TypeScript, HTML, and CSS, and have built rich web interfaces using modern frameworks (ideally React and/or Vue). You write clean, maintainable code and are comfortable structuring front-end applications.
  
  
• Familiarity with integration development: You’ve worked on integrating systems or APIs before – for example, building plugins, extensions, or using REST/GraphQL APIs to connect platforms. Experience with e-commerce or CMS platforms (Shopify, etc.) is a big plus.
  
  
• Flexibility with tech: You’re not tied to a single framework or language. If you primarily know React but need to dive into Vue (or vice versa) or write a bit of Node.js, you can adapt quickly. You enjoy learning new technologies and picking the best tool for the job.
  
  
• Eye for detail in UI/UX: You care about how things look and feel. You pay attention to the finer details of spacing, alignment, and responsiveness to ensure a great user experience. You can take a design/mock-up and turn it into a polished implementation that users love.
  
  
• Autonomous and proactive work style: We value developers who take ownership. You can drive a project from idea to completion, solve problems independently, and aren’t afraid to suggest improvements. Your problem-solving is proactive – if you see an issue or a better way, you tackle it.
  
  
• Strong communication skills: You can clearly articulate technical ideas to teammates and occasionally to partners. You work well in a collaborative setting and appreciate feedback. Since our team is distributed, you’re comfortable communicating in English (our company language for collaboration).
  
  
• AI-first mindset: You are open to using AI in your workflow. Whether it’s using code assistants or experimenting with new AI-driven development tools, you embrace the opportunity to work smarter and more efficiently. (Prior experience with AI coding tools is a bonus, but the key is willingness to learn.)

It is a bonus if you:

• Know our ecosystem: Experience with one or more platforms in our integration list (for example, developing a Shopify app, working with Medusa) will make you hit the ground running.
• Contribute to open source: If you have contributed to open-source projects or maintain your own libraries/plugins, we’d love to hear about it.
• Have backend or full-stack experience: While this role is front-end focused, any familiarity with cloud functions, serverless architecture can be useful.
• Appreciate good design: While not required to do design work, having a sense of design principles or past collaboration with design teams is a plus.

The team & how we work

Joining our Product Development Team means you’ll be at the heart of building new features and integrations that drive our product forward. It’s a small, agile team working closely with our co-founders and other departments. You’ll find a high degree of autonomy – we trust you to take ownership of your projects. At the same time, collaboration is key: you’ll frequently pair with colleagues to brainstorm solutions or review code. We do regular knowledge-sharing sessions and encourage continuous learning (whether it’s a new framework or an AI tool). Our development process is iterative and feedback-driven; we release updates often and learn from how they perform. Since you’ll be working directly with our CPO and other senior developers, you’ll have mentorship and guidance available, but also the chance to influence architectural decisions and product direction. This is a role where your ideas can truly shape the product!

Location & Work Flexibility

Our headquarters is in Aarhus, Denmark (Trindsøvej 8, 1. 8000 Aarhus C), and we have a strong preference for candidates who can join us on-site in Aarhus or within Denmark. Being able to occasionally meet in person, whiteboard ideas, and bond over lunch at the office is a big plus for us. That said, we fully support remote work and flexible arrangements – we already have team members who work from other cities/countries and we collaborate smoothly online. If you’re based outside of Aarhus, we might ask for periodic visits to HQ (e.g., a few days a month) to stay connected. We offer flexible working hours because we know some of us are early birds and others are night owls. What matters is the results and that we communicate well.

(Note: For candidates outside Denmark, we are open to remote hiring for the right fit, but you should be within a time zone that allows for overlap with CET working hours. Unfortunately, we cannot provide visa sponsorship at this time, so you should have work authorization in the EU.)
