F-Secure makes every digital moment more secure, for everyone. For over 35 years, we’ve led the cyber security industry, protecting tens of millions of people online together with our 200+ service provider partners. We value our Fellows' individuality, with an inclusive environment where diversity drives innovation and growth. What makes you unique is what we value – be yourself, that is (y)our greatest asset. Founded in Finland, F‑Secure has offices in Europe, North America and Asia Pacific.

Are you early in your software development career and curious to learn how large-scale, resilient cloud services are built and run in production? If you enjoy solving problems together and learning by doing, this might be the role for you.

We’re now looking for a Junior or Mid-level Backend Developer (Platform Applications) to join our team in Oulu.

In this role, you’ll work as part of the Platform Applications team, contributing to foundational cloud services and internal tooling that other F-Secure teams rely on. You’ll handle concrete development and support tasks, gradually taking on more responsibility as your experience grows. The role combines hands-on backend development with collaboration within the team, offering a clear learning path into production systems, cloud infrastructure, and DevSecOps best practices.

The Platform Applications team builds and maintains core cloud services that form an essential part of F-Secure’s infrastructure. The team supports other F-Secure teams by maintaining shared services and tooling that help backend development and operations. You’ll work with production systems, cloud-based services, and shared platform components, gaining practical experience in how such systems are developed and maintained over time.

Your day-to-day may include:

  • Work on backend development tasks based on Jira tickets and team priorities
  • Contribute to building and maintaining foundational cloud services used across F-Secure
  • Support existing services in production, with guidance and mentoring from the team
  • Communicate actively with team members to avoid blockers and keep work moving
  • Learn and apply best practices in cloud development, DevSecOps, and CI/CD
  • Gradually take on more responsibility and expand your scope as your experience grows

What are we looking for?

  • Junior to mid-level experience in software development
  • Basic skills in Python and scripting (e.g. Bash)
  • Familiarity with AWS services and cloud concepts
  • Ability to communicate effectively in English
  • Curiosity, willingness to learn, and a team-oriented mindset

Bonus points for:

  • Experience with containers or container-based development
  • Familiarity with Infrastructure as Code
  • Exposure to CI/CD pipelines or automated testing

      What will you get from us?

      • Welcome to the good side – the home of scam protection! Work with industry-leading experts defining the future of cybersecurity and scam protection.
      • Be an AI pioneer, not a follower. Access industry-leading tools like Claude and Claude Code, with full support to integrate AI into your daily work while others are still figuring out policies. We're not asking "if" but "how" AI transforms our work, positioning you at the forefront of the industry.
      • Thrive in our Fellowship culture where we empower, trust, challenge, and support each other in doing our best work.
      • Flexible work that works for you – hybrid and remote options with team-agreed ways of working.
      • Inclusive environment with flat, approachable leadership in our diverse global community.
      • Comprehensive global benefits including Employee Share Savings Plan (ESSP), Fellow Member of the Board opportunities, and Annual Protect & Educate paid volunteer day.
      • Wellbeing support through personal coaching services and one hour per week for personal recharging.
      • Continuous growth via F-Secure Academy, Leadership programs, AI training, mentoring, and dedicated Learning Week.

      Our local benefits include extensive health care, remote working, company supported sport activities, lunch vouchers, and many more things to keep our best asset – people - happy!

      A security vetting will possibly be conducted for the selected candidate in accordance to our employment process.

      Fellowship Culture

      The F-Secure team is diverse, fun-loving, and full of energy. Our Fellowship means that “we” are bigger than “me”. Fellowship is the glue that creates trust and accountability, and it is built on our four core values: Keep Focus, I Make a Difference, Just Do It and Dare to Care.

      We keep focus by doing the right things right. We communicate with clarity, set clear goals and execute them on time and with quality.

      We make a difference by acknowledging that every one of us plays a part in making a meaningful impact, and by taking accountability and pride in our work. We support one another and celebrate success together.

      We just do it by encouraging Fellows to make their own decisions. We embrace the freedom and the responsibility that comes with it.

      We dare to care by creating a safe and trusting environment, where we all have a chance to speak up on things that matter, and to give and get feedback.
