Job description

Working Model: Remote-first, with approximately 2 days per month on-site

Employment: Permanent

About the Company

We’re working with an established Nordic online marketplace business operating across multiple consumer platforms.

The business is going through an exciting phase of technology transformation, with a major focus on bringing AI directly into its products, customer experiences and engineering workflows.

The engineering organisation is international, collaborative and relatively lean, giving experienced engineers the opportunity to take meaningful ownership and influence how technology evolves.

The Opportunity

We’re looking for Senior Backend Engineers with an interest in Applied AI to help build the next generation of AI-powered ecommerce capabilities.

This is not a research-focused ML role and it isn’t simply about integrating an LLM API.

You’ll be a strong backend engineer first, while helping design and build production AI capabilities across areas such as:

• Conversational and semantic search
• Retrieval and RAG systems
• LLM-powered product features
• Agentic workflows
• AI tooling and automation
• Machine-learning applications in production

You’ll have the opportunity to work across different teams and technical domains depending on business priorities, with significant ownership from architecture and development through to deployment and operation.

What You'll Own

You could work across a combination of:

• Designing and building scalable backend services and APIs
• Developing AI-powered product functionality
• Building search, retrieval and recommendation capabilities
• Integrating and evaluating LLM-based systems
• Designing distributed and event-driven architectures
• Working with databases, caching and data services
• Deploying and operating services in cloud environments
• Monitoring, debugging and improving production systems
• Making technical decisions around performance, reliability and cost
• Working closely with product and engineering teams to turn business problems into technical solutions

What We're Looking For

You’ll ideally have strong experience in:

• Backend software engineering
• Designing and operating production systems
• Distributed systems
• Scalable APIs and services
• Database design and optimisation
• Production monitoring and reliability

For the AI-focused positions, experience in one or more of the following would be particularly

valuable:

• LLM applications
• RAG
• Semantic search
• Information retrieval
• Recommendation systems
• Ranking / reranking
• Embeddings
• Conversational AI
• Agentic workflows
• ML systems in production
• AI tooling and automation

Technology

The environment includes technologies such as:

• Python
• FastAPI
• MongoDB
• Redis
• Kafka
• Cloud infrastructure
• LLM and AI technologies

You don't need experience with every technology listed. Strong engineering fundamentals and the ability to learn are more important than matching a particular technology checklist.

What Makes This Role Interesting?

Build AI that reaches real users

You'll be working on AI-powered capabilities inside established marketplace products rather than isolated experiments or proof-of-concepts.

The role combines modern AI with proper software engineering: architecture, APIs, databases, infrastructure, reliability and production ownership.

Broad technical ownership

You'll have the opportunity to work across teams and take ownership of problems from initial design through to production.

Work at an important stage of AI adoption

The business is actively building its AI engineering capability, giving you the opportunity to influence how AI is integrated into products and engineering practices.

International engineering environment

You'll work alongside a multicultural team where English is the primary working language.

Working Model

The role is remote-first, with approximately two days per month on-site in Stockholm.

There is no regular business travel requirement.

Who Would Succeed Here?

This role is likely to suit someone who:

• Enjoys being hands-on technically
• Wants to combine backend engineering with AI
• Has experience taking systems into production
• Enjoys solving ambiguous problems
• Likes working across traditional engineering and emerging AI technologies
• Wants meaningful ownership rather than a narrowly defined technical role
• Is interested in the intersection of technology, ecommerce and AI

If you're a strong backend engineer who has already started working with AI — or an AI/ML engineer with unusually strong software engineering foundations — we'd be interested in hearing from you.
