SoSafe has the ambition to become the leading human risk management provider in Europe. Our award-winning awareness platform triggers behavioural change by providing effective and engaging training and simulations on cybersecurity and data protection. Cybercrime is costing the world >$10 trillion annually and growing by 15% p.a. - we invite you to be part of the solution!

We own how users access the entire product. From authentication flows to permissions and authorisation, we ensure frictionless user experiences with industry-leading security. Every single user interacts with our domain before using the rest of the product so we put a lot of effort into making our UX processes seamless, intuitive and confidence-inspiring. Our main objective at the moment is enforcing strong domain boundaries for our resources and migrating from self-developed solutions to a more integrated strategy utilizing trusted industry IAM players.

Here's how you'll make a difference:

  • Take core contributor ownership on business-critical, complex projects from conception to deployment
  • Care deeply about outcomes including end user experience and adoption of internal features
  • Show your aptitude for observability and performance optimisation using tools like Sentry, DataDog, etc
  • Take opportunities to flex both your backend and frontend skills to ensure frictionless user experience across the stack
  • Collaborate deeply with other internal teams to ensure strong tooling and process adoption
  • Use your obsession with quality to ensure robust testing resources, team best practices, a rock-solid CI/CD process and carefully designed releases
  • Own the processes you design end to end - you are the steward of your projects and everyone knows it
  • Become a trusted collaboration partner in a modern Agile/Scrum environment supporting your team mates with thorough code reviews, architecture and implementation discussions and pair problem solving
  • Contribute to an enthusiastic team environment - we help, support and celebrate each other

What makes you a great fit:

  • Proven track record of professional full-stack development success using Typescript + React
  • Robust quality mindset and deep experience with testing and release strategies
  • Systems-thinking mindset - you actively own processes end to end and think deeply about how they interact with other parts of the product and the people around you
  • Comfortable working with (or learning to work with) AI-assisted tooling such as Claude, Github Co-Pilot or Cursor
  • Strong observability and performance mindset and experience being able to quantify and show how your products are used
  • Familiarity with CI/CD and common DevOps processes
  • Collaborative and curious - you care deeply about your team environment and helping to make it the best it can be
  • Strong communication skills in English

What we offer*
