Software Developer (AI-Native development)
About the role
Harvia has just entered the new era — the digital sauna experience — by building intelligent digital products, connected IoT devices, a powerful cloud ecosystem and integrating with wearables.
Harvia Finland Oy is looking for a Software Developer to join Harvia’s new AI-native software development team in Finland.
You will be one of the founding members of a small, high-impact team that defines how we build, operate, and evolve digital sauna experiences — from connected devices to mobile apps, integrating with wearables and cloud platforms.
This is not traditional software development. We are building the future of development itself — using AI agents, LLMs, and automation tools to code, test, deploy, and learn faster than ever before.
What You’ll Do
- Develop modern applications for Harvia’s digital ecosystem (mobile, web, and cloud) and develop the sauna control devices software.
- Collaborate with AI tools and agents in daily development — from design to deployment.
- Participate in the development of Harvia’s new IoT device integrations and digital user experiences.
- Work closely with our in-house developers in Finland, Germany and the USA, and with our external development partners in Finland and other countries.
- Continuously learn and experiment with AI-driven development techniques and participate in defining how AI will transform Harvia’s software engineering culture.
Our technology stack
- Frontend: React/React Native, Typescript, REST & GraphQL, Web/Android/iOS, Playwright UI test automation
- Backend: AWS, serverless/AWS Lambda, containers, Node.js, Typescript, Python, REST & GraphQL APIs, Github Actions based CI&CD, Serverless & Terraform
- Device/firmware: FreeRTOS & embedded Linux, C/C++/Rust/Python, ESP32/STM32/NXP i.MX
Your Background
- 3+ years of experience in software development (frontend, backend, or full stack).
- Strong understanding of modern development frameworks and APIs.
- Enthusiasm for AI coding assistants, prompt-based workflows, and automation.
- Experience with cloud or IoT systems is a strong plus.
- Team-oriented mindset and good communication skills.
- Fluent in English and/or Finnish.
Why Join Harvia?
- Shape the future of wellness through digital innovation.
- Join a global wellness leader with a growing digital and AI innovation agenda.
- Be part of a new AI-native software team at its inception and work with modern tools and freedom to experiment.
- Work on meaningful products that connect technology, health, and wellbeing.
- Collaborate with top developers and partners worldwide.
- Competitive salary, hybrid flexibility, and growth opportunities in a global brand.
This position is primarily based in the Helsinki metropolitan area or the Jyväskylä region. We also offer the flexibility to work partially remotely.
