WithSecure™ protects businesses all over the world from modern threats. We do this through a Co-security approach born from first-hand knowledge that no one can solve every cyber security problem alone. Every single day, our diverse, growing team fights against online extortion, threats to national infrastructure, the unlawful spread of sensitive information, and everything in-between. The best part about working for WithSecure is our people! We are a community of dedicated and passionate professionals that take workplace happiness seriously. If you’re looking for something that’s more than just a job – we’d love to hear from you.

About the role

  • You'll be creating new features/functionality and improving existing functionality
  • We are an end-to-end team; We design, estimate, implement, test, deploy, maintain and monitor our own code. You'll be contributing at every step, from design to monitoring
  • This role will be tailored to the candidate and may be a senior role depending on background and experience
  • Our product processes 100 million events per month (and growing fast!)
  • This role is located in Finland and requires an EU work permit

Key Responsibilities

  • Create highly resilient, well tested, high performing, multi-threaded asynchronous C# code
  • Prototype and research new features and technologies
  • Work closely with teammates and product management to deliver a high quality product
  • Work across microservices to deliver a high quality product

What are we looking for?

  • 7 (or more) years of C# development experience
  • Ideally, candidate will have experience with Google workspace APIs
  • Some previous exposure to multi-threaded asynchronous development
  • This role is primarily focused on C# development (we also have code in Typescript, Python, bash, etc...) - we are looking for someone with the confidence to work outside their comfort zone and a passion to learn new things
  • Previous experience with code reviews
  • We are looking for someone who is interested in growing themselves and learning new skills & technologies. We give the time and space to learn, you bring the enthusiasm
  • Ability to work closely with others and a willingness to have fun and be yourself! We want a teammate, not a robot

Bonus points

  • Some exposure to AWS (or Azure or GCP) and DevOps would be good to have, but not required (we'll share all the knowledge needed, we'll even help you get AWS Certified if you are interested!)
  • Some experience working with relational (SQL) and non-relational databases (NoSQL) desirable
  • Previous experience working in agile/scrum based projects desirable

What will you get from us

  • The chance to have a real impact on WithSecure's newest and most high profile product
  • Challenging and interesting problems that will push you to learn new ideas, technologies and ways of working
  • The chance to work with one of the best engineering teams in WithSecure. The team spirit and culture is probably the single biggest benefit we have to offer
  • A team that is technical, ambitious and friendly, that will share their knowledge and expect you to do the same
  • A team that believes in quality and test automation, and is willing to invest time and effort to continually improve product quality
