Software Engineer - Information Security (SW1)

We are hiring software engineers who are committed to open source and are interested in participating in the development of a new approach to information security.

We have several positions open for anyone knowledgeable and experienced in:

  • C, C++ and/or Rust
  • JavaScript (Node.js)
  • .NET Core
  • Python

With the objective of integrating in our services and/or web teams, the ideal candidate understands basic information security principles, GNU/Linux, OpenPGP.js and Mozilla Web Crypto API (for the web team), cloud services (AWS) and serverless computing.

Experience in the following AWS services is preferable:

  • AWS Cognito
  • AWS Lambda
  • AWS S3
  • AWS Quicksight
  • AWS Athena
  • AWS DynamoDB

More important than the technology aspects of the positions, we value you, as an individual. If you're not experienced with the technologies or services we list but you are dedicated and interested in learning, we’d still like to talk to you.


We are based in sunny Lisbon, even though you could work remotely from anywhere in the world.
