Effektify is now looking for a Junior Backend Developer to help build and improve a platform used to turn marketing, e-commerce, and business data into clearer insights and better decisions.** ## About the role In this role, you will help build the backend of a product that handles large amounts of connected data from many different sources. A big part of the job is to make sure data flows, backend logic, and technical foundations are stable, clear, and easy to keep building on over time. You will work with backend development, databases, integrations, and product logic. The role is hands-on and gives you the chance to grow quickly in a real product environment where backend quality matters a lot. You will work closely with **Martin, our CTO**, and the rest of the tech team, most of which is based in **Halmstad**. Since the team is still relatively small, you will get broad exposure, short feedback loops, and a good chance to learn by building together with experienced developers. ## What you will work on Your work will include a mix of: - Building and improving backend logic, APIs, and product functionality - Working with databases such as **PostgreSQL** and **MySQL** - Supporting integrations between ad platforms, analytics tools, e-commerce systems, and financial systems - Helping improve structure, performance, and maintainability on the backend side of the platform - Working closely with frontend and product to build features end-to-end - Using modern AI tools in development to move faster, test ideas, and improve implementation quality ### Examples of projects and focus areas In the first phase, your work may include areas such as: **Backend flows for connected data** Help build and improve the backend logic that pulls together data from multiple sources and makes it usable inside the product. **APIs and product logic for new features** Support the development of backend functionality that powers insights, recommendations, and other product features. **Improving backend quality as the platform grows** Contribute to cleaner structure, better performance, and more maintainable systems as the product becomes more advanced and widely used. ## Team and setup A large part of the tech team is based in **Halmstad**, and for this role that is the preferred location. We would like you to work from the **Halmstad office around 2–3 days per week**. The rest can be flexible depending on what makes sense for you and the team. This is a strong environment if you enjoy working in a smaller team where decision paths are short, people help each other, and good ideas are taken seriously. You will not be expected to know everything from day one, but your curiosity, learning speed, and willingness to take responsibility will matter a lot. ## What we are looking for ### Required - **0–2 years** of experience in system development, backend development, or similar hands-on work - A university education in **IT, computer science, software engineering**, or a related field — or another background combined with hands-on experience we consider equivalent - Good foundation in backend development and programming - Experience working with databases such as **PostgreSQL** or **MySQL** - Comfortable working with APIs, backend logic, and data flows - **Fluent English**, written and spoken ### Nice to have - Experience with **PHP / Laravel** - Experience with **AWS**, cloud environments, or deployment-related work - Experience with **Infrastructure as Code**, for example **Terraform** - Experience with **Snowflake** or other data warehouse environments - Experience from marketing platforms, e-commerce, or other data-heavy products - Good Swedish, written and spoken ## Who are you? We are looking for a developer who is: - Prestigeless and easy to work with - Curious and genuinely interested in learning fast - Comfortable trying new technologies and better ways of working - Happy to use modern AI tools as part of daily development - Driven, responsible, and willing to take ownership earlier than your title might suggest - Motivated by broad scope and a close connection between product decisions and implementation ## More about Effektify At Effektify, we help companies understand what drives marketing performance and what to do next. Our platform brings together data from sources such as **Google, Meta, LinkedIn, TikTok, analytics tools, Shopify, WooCommerce, and financial systems**. That creates a product environment with a lot of connected data, many moving parts, and a constant need for backend systems that are stable, clear, and scalable. For a backend developer, that means working on more than isolated endpoints. You will help shape how data is collected, structured, processed, and used across the platform. Effektify is a profitable scale-up with **50+ employees** and **350+ customers**. Since 2021, we have grown from a small founding team into a multi-office company with offices in **Halmstad (HQ), Gothenburg, Stockholm, Jönköping, and Berlin**. We have strong momentum, a working product, and a lot of room to shape what comes next. ## Practical details - **Location:** Preferably **Halmstad**, with office presence around **2–3 days per week** - **Employment type:** Full-time, permanent - **Salary:** Fixed market-rate salary - **Start date:** By agreement ## Apply Send your application and a few lines about yourself and why this role caught your interest.
