The Engine Room of a Rocket Ship
Soldera is the "Stripe for Renewable Energy." We are an AI-native startup automating the fragmented landscape of European renewable energy certificates. In 2025, we executed a breakout year: revenue exploded from €13k to €1M with consistent 30% MoM growth. We just secured a €1.6M grant to unify European energy registries and are backed by top investors like Lifeline Ventures and Lemonade Stand.
We are building a billion-dollar company with a lean team of "A-players" from Bolt, Trimble, and LHV. To keep moving at this speed, we need someone to make sure the wheels don't fall off.
The Opportunity
We are looking for a smart, hyper-organized, and conscientious Administrative Assistant (internally known as our "Ops & Research Engine").
This is not a glamorous strategic role where you invent the future on day one. This is a role for a high-achiever (likely with excellent academic grades) who understands that operational excellence is built on details. You will be the right hand to the leadership team handling tasks that allow our senior engineers and sales leads to focus on capturing an $80B market.
If you are smart, great at following instructions, and take pride in clearing a to-do list with zero errors, this is your entry ticket into one of Europe’s fastest-growing climate-tech startups.
What You’ll Do
Your day-to-day will be varied, fast-paced, and execution-focused. You will:
- Master the Bureaucracy: Fill out and double-check complex documents for European Guarantees of Origin registries and handle KYC (Know Your Customer) forms. Accuracy here is non-negotiable.
- AI agent orchestrator: Use AI agents to assist you with repetitive tasks and research.
- Financial Hygiene: Hunt down invoices every month, organize receipts, and ensure our financial data is audit-ready.
- Data Scavenging: Research information and put together reports. Manually scrape data from fragmented websites and fix data entry issues in our internal databases to feed our AI models.
- Sales Support: Log into conference apps to book meetings for our BDs and research prospects to ensure our CRM is pristine.
- Executive & Office Support: Book flights and hotels, curate and send client gifts, and ensure the office runs smoothly (yes, that includes greeting high-value clients and making sure the coffee is ready).
- Whatever is Needed: If a task is necessary for the company to win, research, repetitive tasks, compliance or something else, you will own it.
Who You Are
- Academically Strong: You likely had great grades in school/university. You know how to study, focus, and deliver high-quality work.
- Low Ego, High Standards: You don't mind doing "unglamorous" work, but you are terrified of doing it wrong. You check your work three times before hitting send.
- Tech-Literate: You are comfortable with Excel, Google Sheets, and learning new software quickly.
- Structured: You love checklists. Chaos stresses you out. You are the person who organizes the group project.
- Trustworthy: You will handle sensitive documents and data. Discretion is key.
- Excellent English: Written and spoken.
What We Offer
- The "Foot in the Door": This is a rare chance to work inside a high-growth VC-backed startup. You will sit in the room with ex-unicorn talent and see how a company scales from €1M to €100M.
- Compensation: €1500 – €1800 gross (bruto) monthly salary.
- Ownership: A generous stock options package. If we win, you win.
- Culture: A trust-centric environment. We don't micromanage time, we measure results.
- Office: Cool office vibes in Tartu with a high-performance team.

We don't need a cover letter full of buzzwords. We need proof of competence.
