Our international team, spanning from Europe to the Americas, delivers a comprehensive, all-in-one solution to thousands of merchants worldwide. We offer seamless integrations with industry leaders, including Amazon, eBay, Shopify, DHL, and FedEx.

However, we are more than just a technology company. We are one of the fastest-scaling platforms in the sector, having achieved 15x growth over the past three years. We cultivate a culture where tangible impact and collaboration are paramount, with our team being the driving force behind our innovation.

Currently, we are looking for a Business Intelligence Developer (SQL, PowerBI) to take a key role in our data experts team and transform data into actionable insights that will shape the company's dynamic growth strategy. You will play a key role in every stage of the development of our reporting platform, taking end-to-end ownership from gathering requirements, data ingestion and warehousing, through robust data modelling and validation, to the creation of meaningful insights and reporting that enable informed strategic decisions and drive operational excellence across the business.

We seek curious "doers" who are passionate about data analyses and thrive in a role that combines deep technical expertise with strategic business understanding.

You’ll be a perfect fit for this role if you have deep expertise in data warehousing and visualization (using Microsoft PowerBI), exceptional analytical and technical skills (advanced SQL proficiency is essential), and a business-first mindset with the ability to think critically and strategically.

• Proficiency with version control (Git)
• Flexibility to quickly adapt to changing priorities within a very dynamic startup environment
• Effective and flexible communication skills, including the ability to translate technical details into business and commercial objectives, and vice versa
• A proactive communication style – you’re not afraid to challenge the status quo and articulate your vision to both technical and non-technical stakeholders
• Self-driven and detail-oriented mindset while working with data
• Nice-to-have: hands-on experience with AWS data components, like Iceberg, S3, Glue and Redshift for transformation, ingestion and storage of data
• Nice-to-have: experience AI-driven data structures development

Tasks

• Own the full lifecycle of BI development: from gathering and challenging business requirements to solution design, deployment, and fostering end-user adoption
• Act as a key partner for business stakeholders and data engineers, effectively translating business needs into robust technical solutions
• Design, develop, and maintain scalable and robust Business Intelligence solutions using our modern tech stack (AWS Redshift, AWS RDS, Microsoft PowerBI, Git, AI tools)

• Perform both ad-hoc data analysis and build automated reporting solutions that empower business users

• Pivotal role in an expert team where your contributions have an immediate and visible impact on the business
• Chance to develop opportunities in the modern up-to-date cloud technologies environment
• Casual and friendly atmosphere at work and the ability to work with an international team of passionate professionals
• High level of ownership and a real impact on our data strategy
• Growth opportunity in a place focused on long-term collaboration and your personal growth
