Your mission
As an IT Systems & Security Engineer, you take full operational ownership of core security and infrastructure topics across Seven Education. You ensure that our systems are secure, stable, and compliant - not by coordinating from the sidelines, but by being hands-on where it matters most. In a highly autonomous setup, you reduce security debt, establish clear standards, and create reliability across multiple companies and countries.
What you’ll do
- Own day-to-day security operations, including vulnerability handling, follow-ups, and patching
- Maintain, operate, and improve Linux-based systems (e.g. VPN, internal platforms, shared services)
- Take ownership of MDM and endpoint security (Intune, macOS, Windows, Microsoft Defender)
- Support and operate Microsoft 365 and Azure AD, including access controls and identity management
- Reduce security debt and close open findings, especially in the context of ISO 27001
- Document, standardize, and continuously improve recurring security and infrastructure processes
- Act as a reliable operational counterpart for engineering, IT, and leadership stakeholders across the group
What you’ll bring
- Several years (approx. 5+ years) of hands-on experience in system administration, IT infrastructure, or similar roles
- Strong practical experience with Linux administration and operating production systems
- Proven experience handling vulnerabilities, patching, and security-related operational tasks
- Solid working knowledge of Microsoft 365, Azure AD, Intune, and Microsoft Defender
- Confidence in making independent changes in production environments
- A security-first mindset combined with pragmatic decision-making
- Clear, structured communication and a high sense of ownership and reliability
- Curiosity, adaptability, and a strong learning mindset in a changing environment
- Professional working proficiency in English and Spanish
- Experience with ISO 27001, scripting (Bash or PowerShell), or VPN/DNS/firewall setups is a plus, but not a requirement
Where you’ll be
This role is based in Madrid or Girona and works in a hybrid setup. You combine flexible remote work with regular onsite presence at one of our hubs, as personal exchange is key to how we collaborate, learn and grow together. Being on site supports close teamwork, alignment with Sales and a strong connection to our culture.
What we offer
- Purpose & Social Impact: Working in education means making a real difference. At Seven Education, you contribute to improving the daily work of schools and shaping the future of education for a better tomorrow.
- Flexibility & Hybrid Work: We work in a hybrid setup that combines flexibility with collaboration. This includes flexible working hours, the option to work remotely and a regular onsite presence to support teamwork and connection. Working hours are shorter on Fridays.
- We Take Care of Our People: Your well-being matters to us. In case of sick leave, we cover 100% of your salary from day one.
- Learning & Development: We support your personal and professional growth through development opportunities, learning initiatives and the chance to grow within an international software group.
- Team & Collaboration: You will be part of a collaborative and supportive team environment. We believe great teams are built through trust, connection and shared experiences, and we actively create space for this in everyday work.
- Ownership & Growth: We combine a start-up mindset with the stability and ambition of a growing European group. You will have the opportunity to take responsibility, contribute your ideas and actively shape our future together.
- Time Off & Everyday Perks: You receive 23 days of paid vacation per year. Coffee, tea and cold drinks are available in our offices, and we value spending time together beyond day-to-day work.
Diversity Statement
At Seven Education, we believe that diversity drives innovation and inclusion strengthens collaboration. We welcome people of all backgrounds, identities, and perspectives, because transforming education for a better tomorrow starts with equal opportunities today. If you’re excited about this role but don’t meet every requirement, we’d still love to hear from you.
