We are looking for iOS developers at all levels (senior, mid-level, junior). Come and work with us to ensure we can deliver amazing cyber protection to tens of millions of users across over 50 countries globally!

At F-Secure, we develop best of class research-led cybersecurity products that outperform the competition. We have a clear track record of delivering best-in-class applications (https://www.f-secure.com/en/ab...).

The world’s best protection capabilities won’t matter if we can’t build them into great apps. Working on our mobile client applications, you’ll be developing and delivering cybersecurity to consumers across the world.

We are very focused on ensuring we can deliver our products to as many users as possible. We reach some of our users through our own direct sales, but the majority of our users come through service provider partnerships – telco operators, insurance companies, utilities and banks. All of these partners have different brands, licensing models etc. We work at scale in more ways than most. We reach tens of millions of users, through hundreds of mobile apps.

At our scale adopting new APIs offered by platforms requires solving hardcore UX, architecture, and technology challenges is - and we’d love for you to come work with us …

If you join us now, you’ll find yourself working on a couple of key strategic projects:

1. Identity Protection

Another week, another data breach. We help users protect themselves before it happens, recover afterwards and learn good identity protection habits. This is a fast-growing market with enormous customer demand and a strong roadmap for growth.

2. Holistic security

For our consumer users, cybersecurity isn’t just about identity protection, or online privacy, or home IoT security, or antivirus endpoint protection – it’s about having complete security for all their devices, across the board. We are bringing together all of our security capabilities into one framework to deliver customized all-in-one cybersecurity applications.

We’ve got ambitious roadmaps on both of these projects, and we need mobile application development to make sure we can bring these major advances to market – both to our existing userbase, and to new users.

Plus, there’s a lot more that we are working on as well. We actively encourage our developers 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.
