Stockholm, Stockholm, Sweden Helicon Technologies AB Full time

What we do

At Helicon, we build digital products that matter. As a digital product development & innovation agency specializing in cleantech, we partner with forward-thinking businesses to build breakthrough digital products, platforms, and capabilities that drive sustainability and efficiency.

Who we are

Our journey has taken us from developing one of Sweden's largest virtual power plants by connecting over 15,000 buildings, to using AI to optimize energy, water, and resource management around the world. We have also helped launch award-winning cleantech startups and SaaS solutions for the energy sector.

But we don't just measure success by the impact we have on our customers. We measure it by the real-world sustainability gains our solutions create. When our customers tell us that our solutions helped shut down a coal and oil power plant, integrate more renewables into their portfolio, or cut 36,000 tons of CO₂ emissions annually, we take immense pride in that.

What truly drives us is our passion for solving complex challenges together by combining strategy, design, engineering, and data science. At Helicon, speed, curiosity, collaboration, and continuous learning are at the heart of everything we do. If you're passionate about technology and in using it to make a positive impact on our planet, you'll fit right in with our team.

About the role

As a Fullstack Engineer, you will balance your work between the backend and frontend, collaborating with colleagues on the same project. You'll have a significant technical and organizational impact, driving both solutions and long-term innovative initiatives. You will be involved in the entire product-building journey, from design and development to testing and implementation. It will be fast-paced, challenging, and rewarding.

What you'll do

  • You will typically focus more on the backend stack of a specific project, but there are projects where support on both sides is needed, and front-end focus may shift between projects.
  • Provide mentoring and drive the team forward in terms of development methodologies.
  • Rapidly and precisely plan and execute application development projects.
  • Understand customer's needs to help define requirements.
  • Perform constructive code reviews and provide meaningful feedback.
  • Build and lead development teams and initiatives.

What you'll bring to the table

  • 5+ years of experience with a reasonably up-to-date backend stack, preferably with Python, along with experience in frontend development.
  • Experience with running deployments on AWS and/or Azure.
  • Strong understanding of Docker and Git.
  • Fundamental understanding of profiling and performance optimization.
  • Ability to build applications that can handle large amounts of data while remaining highly responsive.
  • Strong opinions on how to best connect applications with external APIs.
  • Able to work in a hybrid setup in Stockholm and fluent in Swedish and English.

What we offer

At Helicon, you can expect to work alongside truly tech-passionate people every day. What we do has a big impact on building a more efficient future, which gives us pride in our work. We foster a culture of humble collaboration, where we are always eager to learn and innovate. We prioritize balance between your job and private life and regularly host social activities like hackathons, after-work gatherings, yearly conferences, shuffleboard comps, and more

Application

Even if you do not meet all the requirements, we encourage you to apply, as our number one priority is to hire the right people instead of nitty-gritty tech.

Our recruitment process usually consists of a first interview, a technical step followed by a business and culture-focused interview.
