We are a next-gen energy company leveraging AI and machine learning to make renewable energy stable and always available - even when the sun isn't shining and the wind isn't blowing.
Through smart optimization and trading of energy assets like wind and solar farms, battery systems, and EV chargers, we make renewable energy reliable and predictable, leading the charge towards the energy system of tomorrow.
Who We Are Tech company at heart - purpose in our DNA. Flower consists of a diverse group of innovative individuals with a strong desire to improve the state of the world.
At Flower, we believe trust, collaboration and diversity are essential to not only create an inclusive work environment, but also drive career growth. By embracing varying perspectives, we allow creativity and progress to flourish.
To accelerate towards our goal of becoming the pioneering force powering the energy system of tomorrow, we are now looking for a passionate and skilled intern in the EPC Team (Engineering, Procurement, and Construction) for a paid summer internship.
This isn't a coffee-fetching internship. You'll be building, learning, and making things happen alongside a team that moves fast, thinks big, and genuinely enjoys the ride.
If you're looking for the most impactful - and exciting - internship of the summer, you've just found it.
About The Role:
You'll join the EPC team to help develop the next version of our CAPEX estimation tool for energy infrastructure projects, with a strong focus on Battery Energy Storage Systems (BESS).
The goal is to move from high-level estimates to data-driven, country-specific, and scenario-based cost modelling. During your internship, you'll play a key role in building a robust cost database and improving how we estimate project costs across different markets.
This is a hands-on role where you'll work at the intersection of engineering, data, and commercial decision-making, contributing directly to real project development.
What You'll Do:
Develop a cost database for BESS projects across multiple European countries, site conditions and project configurations
Research and validate cost data for different budget categories (civil works, electrical works, equipment, logistics, etc.)
Engage with the market to verify and collect benchmark data
Support the development of an Excel-based calculator, improving inputs, assumptions, and overall accuracy to build a scalable and reliable tool for the company
Collaborate with engineers and project developers to ensure assumptions reflect real-world conditions
Who You Are:
Strong analytical mindset, with an interest in how technical and financial aspects of infrastructure projects come together
Comfortable working with Excel and structured data (formulas, logic, organisation of datasets)
Comfortable communicating with external stakeholders and suppliers
Detail-oriented and able to work independently with open-ended tasks
Studying (or recently graduated in) Civil Engineering, Industrial Engineering, Construction Management, or similar
Currently in the final years of your academic journey, or recently graduated
Fluency in spoken and written English
Eligible for work in Sweden
You are based in Stockholm
Available for work from June 8th, for about 8-10 weeks, full time (40 hours per week)
Nice to have:
Additional European languages (especially German, French, Dutch, or Swedish)
Basic understanding of construction processes, electrical systems, and energy infrastructure
Experience with cost estimation, procurement, or project planning (academic or internship level is enough)
Experience working with large datasets or building structured tools in Excel
What's in it for you:
A paid internship
A fast-moving, high-impact tech environment
Hands-on experience with large-scale infrastructure projects
Gain exposure to BESS, EPC processes, and procurement decision-making
A steep learning curve alongside top engineers and traders
A diverse, international team and strong professional network
Great office in central Stockholm (Slussen) with the best view in the city
An in-office gym to kickstart your mornings or reset after a productive day
A constantly stocked selection of snacks, coffee, and treats to keep your energy (and mood) high
Location
Our beautiful office is located in the heart of Södermalm, just a short walk from Slussen subway station. We encourage in-office collaboration but support a hybrid work model.
Apply
Our corporate language is English, as we have about 30 nationalities in the office. We therefore appreciate it if you could submit your CV in English.
Throughout the recruitment process you will meet with the Hiring Manager, members of the team, and the Talent Partner.
We look forward to hearing from you!
