About us

At Kleo (www.kleohub.com), we are redefining how businesses access financing. We combine proprietary technology and AI with expert backing to eliminate bureaucracy and simplify access to public funding, bank loans, and private investment through automated, end-to-end workflows.

We are looking for an Admin & Finance Specialist to join our Operations team, reporting directly to our Operations Manager. You’ll take ownership of the company’s admin and accounting, and grow with us as we scale.

- Manage day-to-day bookkeeping in Holded: supplier invoices, expenses, receipts and direct debit batches.
- Handle client invoicing and collections, including follow-up on unpaid invoices and refunds.
- Act as the main point of contact with our external accounting and tax advisors: tax calendar, deadlines and requests.
- Keep company documentation organized and accessible: contracts, insurance policies and corporate records.
- Oversee tools and suppliers: inventory, costs and renewals.
- Coordinate office management and employee onboarding and offboarding (equipment, access and permissions).
- Support the documentation and reporting of the public grants the company receives.
- Document processes and keep our internal knowledge base up to date.

? What we’re looking for

- Degree in Business, Economics, Accounting or a vocational qualification in Administration and Finance.




- 1–3 years of experience in accounting or administration.
- Hands-on experience with Holded.
- Solid knowledge of general accounting and the basic tax obligations of a Spanish company.
- Organized and rigorous, with the ability to document processes clearly.
- A proactive, self-starting mindset and eagerness to learn.
- Interest in the startup world and in understanding how the business works beyond the numbers.

✨ Nice to have

- Professional English.
- Startup experience.
- Familiarity with HubSpot or Notion.

? What Kleo offers

- Work model: Hybrid (3 days a week in the office).
- Salary: Competitive, based on experience.
- Real ownership over the admin area, with a direct impact on how the company runs.
- The opportunity to take on new responsibilities and build your career within the company.
- Tech & AI powered: work with an ecosystem of digital and AI tools built to remove the boring, repetitive admin work.

? Why join Kleo?

We’re on a mission to fix financing for SMEs and scale-ups, using AI to remove the complexity and inefficiency that has held these companies back for decades. This is a chance to see how everything connects in a growing company, and to grow your career alongside it.

If you’re organized, reliable and eager to learn, Kleo wants to hear from you.
