Join Aira's mission to transform Europe's energy future

Are you passionate about building exceptional web experiences that drive growth and build iconic brands? Join Aira, a pioneering Swedish tech company, and help us craft our digital front door with cutting-edge frontend technology!

Aira is at the forefront of clean energy technology. 10% of Europe's CO₂ emissions are caused by residential heating, and energy bills are out of control. Aira is here to change that.

With our intelligent Aira Heat Pump at the heart, we're making the switch to clean energy-tech easier and more affordable. Helping Europe turn off gas and slashing energy costs one home at a time.

Founded in 2022, and with 1000+ employees and counting, Aira is driving the clean energy revolution by providing homes with modern clean energy-tech solutions such as solar power, battery storage solutions and heat pumps. With a state-of-the-art production facility in Poland, an HQ in Stockholm, Sweden, and hubs across the UK, Germany, and Italy, Aira is well on track to install clean energy-tech into 5 million homes by 2034.

About The Role 

This is a unique opportunity to own the technical foundation of our public web platform. You'll make the calls on architecture, wrangle technical debt, optimise for performance at scale, and balance shipping fast with building right—working alongside growth and data to prove the impact. Your work sits at the heart of our business, where everyone, from leadership to the markets, feels invested.

As one out of two engineers you'll work in a team consisting of a designer, product manager, CRO specialist, SEO specialist and CMS specialist where your technical decisions directly shape what customers see first and how the business scales.

What You'll Be Doing


  • Build our public web platform in React and Next.js. Own the technical decisions—from architecture choices to how fast we ship vs. how well we build.
  • Work directly with growth and data to use real data to decide what's worth optimising and what's not.
  • Own Core Web Vitals, SEO, and A/B testing infrastructure. Build the tools that let us test ideas quickly and measure what actually works.
  • Implement a headless CMS that allows marketing and regional teams to publish content independently, eliminating the need for engineering assistance. Keep it performant and maintainable while giving them the flexibility they need.
  • Deploy to Vercel, set up CI/CD, monitor metrics, and fix issues.
  • Shape the product as much as the code. Beyond development, you’ll participate in discovery and decision-making — influencing how we reach 5 million homes by 2034.


What You'll Bring To The Role


  • React & Next.js experience — 3+ years building production-grade applications using modern patterns (SSR, SSG, ISR, API routes)
  • Systems thinking — ability to design, scale, and evolve architecture in line with fast-moving business needs
  • Headless CMS integration — proven track record with Contentful, Sanity, Strapi, or similar


Professional Requirements:


  • 4 days per week in our Stockholm office
  • Strong English communication skills
  • Experience working in fast-paced, growth-focused environments


Please note

As summer is a time when many of our team members are on vacation, our recruitment process will be slower than usual. We may not be able to review applications and start interviewing until early August, once everyone is back.

Thank you for your patience and understanding. We truly appreciate your interest in joining us, and we look forward to connecting with you soon!

What is in it for you?


  • Gain hands-on experience in a fast-growing scale-up, with a supportive and inclusive culture, and career advancement opportunities
  • Collaborate with diverse teams across international markets and launch products globally
  • Develop and grow personally and professionally in an entrepreneurial-minded environment
  • Thrive in a dynamic, solution-oriented culture, tackling challenges and driving meaningful solutions that make a positive impact on the world
  • Influence the company's success, with a visible impact on product development and market growth
  • Work with cutting-edge frontend technologies and modern development practices
  • Enjoy our brand-new office at Norra Stationsgatan 93 in Stockholm. Conveniently located near public transport, with Sankt Eriksplan and Odenplan stations just a few minutes walk away
