Lead System Administrator (Defence & Security)

Reaktor’s Defence & Security Unit is looking for an experienced, hands-on Lead System Administrator to join our internal IT team

in Helsinki.

Our team builds and maintains secure and reliable IT environments that DefSec’s development teams depend on. The work ranges from

daily maintenance and troubleshooting to automation, security, and longer-term infrastructure development.

AS A LEAD SYSTEM ADMINISTRATOR, YOU WILL WORK HANDS-ON AS PART OF THE TEAM: BUILDING AND MAINTAINING SYSTEMS, DEVELOPING

AUTOMATION, AND SOLVING TECHNICAL PROBLEMS. ALONGSIDE YOUR TECHNICAL RESPONSIBILITIES, YOU WILL TAKE OWNERSHIP OF THE OVERALL FLOW

OF THE TEAM’S WORK.

You will keep the backlog clear, bring together technical and business needs, and facilitate prioritisation together with the team

and business stakeholders. In our low-hierarchy environment, your role is to help the team maintain a shared understanding of what

matters most, navigate competing requirements, and move the right work forward.

• Working closely with developers, business stakeholders, and consultants to understand and translate their needs into actionable

work.

• This position requires Finnish citizenship due to client and security regulations. The selected candidate must successfully

complete a security clearance process.

For two decades, we’ve been developing qualities and capabilities for adapting, reacting, and supporting change – building Reaktor

to hold up in a fast-paced environment while ensuring the well-being of our people.

• An opportunity to work with our DefSec’s internal IT team to ensure our consultants have access to secure and efficient

environments. Your work directly supports our critical security-focused software projects.

• The ability to impact how you work. Together with your team, you choose the approach, technologies, and methodologies you think

will work best in any given situation.

• Career development, helping you develop your skills further through guidance and/or courses, and giving you the opportunity to

explore your career interests.

• A sustainable work-life balance and support for your daily life outside of work. (e.g., free moving day, Reaktor car share,

sick child care services, office space to use for your private events, etc.).

• Many different hobby clubs, from winter swimming and running to knitting and archery, that bring people together outside of

(and sometimes inside) office hours. Many of these are supported by Reaktor.

Together, we are committed to making Reaktor an environment that embraces and values all of our employees for the whole of who

they are. We encourage applicants from all backgrounds to apply, knowing that studies show that members of underrepresented

communities don’t apply for jobs unless they fully satisfy all of the requirements. If you're thinking twice about applying for

this reason, we invite you to send us your application anyway. You could be just the person we're looking for.
