Senior AI Engineer
PLAYipp AB · Gävle · Tills vidare
PLAYipp AB is hiring a **Senior AI Engineer** to join its team at the headquarters in central Gävle. In this role, engineers own features end-to-end from product requirement documents through to production, covering frontend, backend, testing, and architectural decisions. A defining aspect of the workflow is that development is carried out by directing AI coding tools such as Claude Code rather than manual coding, with engineers remaining fully accountable for shipped code. Core responsibilities include integrating AI-powered capabilities into the digital signage platform using LLM APIs, building internal self-service tools for non-engineers, and mentoring team members. The position operates on a hybrid schedule requiring a **minimum of three days per week on-site** in Gävle alongside core collaboration hours. Candidates must possess at least seven years of professional full-stack development experience alongside practical experience deploying AI- or LLM-powered features in production. Applicants should already use **AI-directed development** as their standard way of working, with the expertise in TypeScript, React, Node.js, and relational databases like MySQL necessary to evaluate, architect, and maintain AI-generated code. Comfort with end-to-end feature ownership and adaptability across shifting product and internal tooling priorities are also required.
We're looking for a Senior AI Engineer
Join us in transforming the digital signage landscape. PLAYipp, the leading Nordic digital signage company, is seeking a senior engineer to own features end-to-end — from PRD to Production — which increasingly include building AI capabilities directly into our product. At PLAYipp, we don't write code by hand — everything is built by directing AI coding tools (we use Claude Code), and you're fully accountable for what ships, however it was written. You'll be working in a Team, alongside Product and fellow Engineers — each of you carrying a bigger slice of the work than in a traditional setup, but never working alone.
About PLAYipp
At PLAYipp, we deliver comprehensive, user-friendly digital signage solutions that empower businesses to communicate effectively and innovate. Our platform enables organizations of all sizes to manage and showcase content seamlessly across various screens, enhancing communication and customer engagement.
We're also at the forefront of how software gets built, constantly pushing for new ways to work more efficiently with AI without ever compromising on code quality. If you like being at that edge, this is the place.
Key role description
You own features end-to-end: front end, back end, testing, and the architecture decisions along the way. You're never on your own with this — your team, our chief architect, and our Head of AI are there to support you whenever you need it.
Beyond product features, you'll also help build AI into how the whole organization works — tools that let AI handle work that used to require an engineer.
What we expect from you
Building, Testing & Maintaining the Product
- Take requirements from PRD to finished, deployed feature.
- Write and maintain tests as part of building — quality is your responsibility.
- Ownership — you ship it, you're responsible for it in production.
- Think about scalability and architecture, together with our Chief Architect, as a natural part of building, not an afterthought.
Building AI Into the Product
- Build AI-powered capabilities into the PLAYipp product itself.
- Work with LLM APIs and related tooling to get these features to production, not just prototypes.
Internal AI Enablement
- Occasionally build internal tooling that helps the wider organization become more self-sufficient with AI — e.g. giving non-engineers direct, self-serve access to data that used to require an engineer.
- Bring in new AI tools and workflows as they prove useful, and keep pushing for more efficient ways to work with AI without compromising quality.
Team Collaboration & attitude
- Share knowledge — on architecture, testing, deployment, and AI tooling — through documentation and workshops.
- Help team members grow their technical skills, including AI-assisted development.
- Lead by example in communication, drive and creativity.
- Foster a collaborative, learning-oriented team culture.
Required CompetenciesTechnical Skills
- 7+ years of professional experience in full-stack development, with demonstrated progression in technical complexity and responsibility.
- Practical experience building AI/LLM-powered features in a production product.
- Strong expertise in TypeScript, React, and Node.js — enough to review, judge, and be fully accountable for AI-generated code. Even though AI writes it, you own every line and are the one who fixes it when it breaks.
- Deep understanding of modern web application architecture, including RESTful APIs.
- Proficient with relational databases (MySQL or similar), including schema design, query optimization, and data modeling.
- You shouldn't have been coding manually for some time; Claude Code experience specifically isn't required, but AI-directed development should already be how you work.
- Comfortable with ownership, not just writing code and passing it along.
- Nimble and adaptable — comfortable moving between product feature work and internal tooling/enablement work as priorities shift.
Location & Schedule
- Hybrid but primarily based, 3 days/week minimum, at PLAYipp HQ in central Gävle.
- Core collaboration hours for team synchronization.
Why Join PLAYipp?
- Work with a talented and enthusiastic team in an innovative and growing company.
- Shape how AI gets built into a market-leading product, not just talk about it.
- Be part of a small, tight-knit team where you carry real ownership — without working alone.
- Enjoy a dynamic and collaborative work environment that values creativity and initiative.
- Opportunity to make a significant impact on the digital signage industry.
- Competitive salary and benefits package.
