Job description

Join our newly formed Discovery Agent Experience team and work closely with skilled developers in building the next-generation search experience within Voyado Product Discovery. We already have a powerful and proven search engine. Now, we are adding an intelligent layer on top, an AI Product Discovery Agent for Search that transforms how users interact with products, navigation, and intent. As this is a new team, you will be part of shaping our ways of working, defining our architecture, and setting the technical roadmap for how AI agents should integrate with and enhance our search platform. Our mission is to build intelligent agents that orchestrate search recommendations and navigation, interpret user intent, and create a completely new discovery interface experience.

About The Role And Day-to-day

This role sits at the intersection of backend development, AI engineering, and product innovation. The team is in an early phase, as is the technology, and besides design and development your work will touch commercial aspects like product-market-fit and go-to-market planning. You'll work with hands‑on development; including designing and orchestrating AI agents, refining prompts, and optimizing structured outputs to deliver high‑quality, reliable results. You’ll also build smart integrations between LLMs and our search engine. Together with the team you'll own the technical roadmap and architectural decisions, proactively prototype new ideas, and evaluate emerging AI technologies to ensure we stay at the forefront of innovation. Some things will vary depending on product needs and experiments, but some things are constant.

• Design and build AI agents for search and product discovery, using Java and/or Python.
• Map agent logic towards our existing search infrastructure
• Optimize for latency, scalability, and cost‑efficiency (LLM usage, orchestration, caching, etc.)
• Evaluate new technologies in a rapidly evolving AI landscape
• Design and implement APIs
• Continuously improve response times and reduce inference costs to create scalable and efficient solutions

When the time comes when you need a break, you can spend some time in the gym, tinker in our puzzle corner, or challenge our Åre office in Call of Duty on our PlayStation 5.

So, who are you?

You don’t just follow AI trends, you actively build with them. Agentic coding is already a natural part of how you develop software, and collaborating with LLMs feels as intuitive as writing code yourself. Writing prompts to generate, refactor, and reason about code is a natural extension of your engineering workflow. At the same time, your interest goes beyond just experimenting as you thrive on building real products. You enjoy turning ideas into robust, production‑ready systems and combining AI‑native development patterns with solid software engineering principles. And since this is a newly formed team, you’re excited not only to build the product but also to shape how we build it, driving evaluation frameworks, testing strategies for LLM‑based systems, and establishing pragmatic, high‑quality ways of working for AI‑driven development.

Besides those personal skills, we believe you have the following:

• Master of Science in Engineering (MScEng) in Computer Science and Engineering, Engineering Physics, Engineering Mathematics, or similar.
• Excellent programming skills and a strong understanding of data structures
• Familiarity with concurrent programming
• A solid understanding of fundamental algorithms
• Practical experience working with LLMs and AI APIs, either in hobby projects or in your work
• Experience or strong interest in prompt engineering and agent design
• Strong mathematical, analytical, and problem‑solving skills
• An understanding of performance optimization and cost‑aware system design

And most importantly, passion for what you do, innovation & continuous improvement. If you are interested in algorithmic problem-solving, that's meritorious.

Some of the technologies you’ll get to work with

• Java (latest version)
• LLMs and agents (Anthropic, OpenAI, Bedrock, MCP)
• Search and embeddings
• AWS (Bedrock, DynamoDB, Lambda, ECS/Fargate, S3)
• Terraform
• GitHub Actions
• OpenTelemetry och Coralogix

So, what's in it for you?

• You’ll get to work in an area that’s evolving incredibly quickly right now, and the team works with cutting‑edge technologies in AI and search. The ambition is to stay at the forefront and explore what becomes possible when the latest AI models are combined with search and product data at scale.
• A lovely worksite in Lund, in our own Voyado house on Gasverksgatan.
• Flexible working hours and a hybrid work approach. We’re on‑site at least three days a week.
• Work‑life balance – We don't have a long work‑hours culture; we value results over hours worked.
• As we strive for our employees to share Voyado’s passions and goals, you should demand no less from us. With regular one‑on‑ones, we make sure your needs and career have a great future at Voyado.
• Joining an engaged team and colleagues with a knowledge‑sharing and friendly culture.

Some of our benefits

• A health hour each week, use it for walks, running, or working out – whatever you need to energize
• Our own gym at the office
• 30 days of vacation so that you can spend time with family and friends
• 5000 SEK in wellness allowance
• Encouragement to further develop personally and professionally with certifications, meetups, etc.
• Beneficial bike lease, including e-bikes
• Your choice of phone and gadget package
