Job Description

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 passionate about scalable cloud infrastructure, workflow automation, and creating developer-friendly platforms? We’re looking for a Lead Developer to join our Platform Core Team in Helsinki, where you’ll play a key role in improving how we work and building tools that empower developers. You’ll help ensure our cloud infrastructure and development processes run smoothly, all while working with modern tools in an environment that values continuous learning. Collaboration is central to our team, and you’ll join skilled professionals who share knowledge and grow together. With hybrid work options, team-building activities, and a culture that values balance, you’ll have the flexibility to do your best work.

At F-Secure, innovation is at the core of everything we do. Our Platform Core Team plays a crucial role in supporting the entire F-Secure Technology organization by delivering powerful development and production tooling, scalable environments, and streamlined workflows. We don’t just provide solutions—we design the systems that make building secure and scalable products easy for our developers. Together, we’re driving automation, scalability, and efficiency across our cloud infrastructure to accelerate the pace of innovation.

Our hiring process consists of two interview rounds. First, you'll have an introduction interview, followed by a technical pre-task. In the final stage, you'll meet with the team to review your pre-task submission and dive deeper into technical discussions, as well as team and culture fit.

Here's a glimpse of the key responsibilities in this role:

As a Lead Developer in Platform Engineering, you will take charge of cloud infrastructure and developer platform development, working closely with a team of 9-10 talented engineers. Reporting to the Engineering Lead, Platform Core, you will play a critical role in automating cloud configurations, CI/CD tooling, and developer workflows to improve productivity and operational efficiency.

• Lead infrastructure and platform automation: Drive automation of cloud infrastructure provisioning, configuration, and developer portal flows.
• Enhance developer experience (DevEx): Design and optimize tooling and processes to improve developer efficiency across the organization.
• CI/CD and networking automation: Develop and maintain CI/CD pipelines, container orchestration, and automated networking solutions.
• Cross-functional collaboration: Work closely with teams across the organization, including development and production operations teams, to implement scalable solutions.

What are we looking for?

We’re seeking someone who thrives on collaboration, takes initiative, and enjoys solving challenges with a proactive mindset. Having a strong foundation in cloud development or infrastructure engineering, along with relevant AWS certifications and senior-level experience, will help you succeed in this role. But beyond that, strong communication skills, an open mind, and a team-oriented approach are just as important as technical expertise. If you’re ready to work with others to create practical and impactful solutions, we’d love to hear from you!

• Expertise in cloud infrastructure: Deep understanding of AWS cloud and network architectures.
• Infrastructure automation: Hands-on experience with automating cloud configurations, CI/CD pipelines, and container orchestration.
• Cloud security and compliance: Familiarity with securing cloud environments and maintaining compliance standards.
• Programming and scripting: Proficiency in scripting languages and infrastructure as code tools (e.g., Terraform). Bonus points for front-end programming or Go experience.
• We offer a hybrid working model, with flexibility to work remotely. However, we prefer that the chosen candidate is willing to visit our Helsinki office 1-2 days a week to foster collaboration and team engagement.

What will you get from us?

In this role, you'll have the opportunity to shape and drive the SRE strategy for F-Secure, playing a key role in ensuring the reliability, scalability, and performance of our cloud services. You'll work as part of a bigger talented team, collaborate with cross-functional partners, and work with cutting-edge observability tools and processes to continuously enhance our systems. This role offers a chance to make a significant impact on how we approach reliability, incident management, and automation, while also fostering a culture of continuous improvement and innovation.

• You will work together with experienced and enthusiastic colleagues, and within F-Secure you will find some of the best minds in the cyber security industry.
• We actively encourage our Fellows to grow and develop within F-Secure, and in your career here you can find yourself contributing to any number of our other products and teams. You decide what to make of this role, what your priorities are, and how you organize your work for the best benefit to us all.
• We offer interesting challenges and a competitive compensation model with wide range of benefits. You get a chance to develop yourself professionally in an international and highly motivated team serving our customers in providing world class security, privacy and uncensored access to information online.
• You get to work in a flexible, agile, and dynamic working environment that supports individual needs. Giving our people both support and the opportunity to be in charge of their own work is something that is in our DNA.
• We are in a unique phase in our 30-year history and with curiosity and excitement in the air we see no limits for building a strong and fruitful career with us!

Our benefits include extensive health care, remote working, company supported sport activities, lunch vouchers, regular massages and sauna at the premises 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.
