Security Engineer

Role overview Help strengthen the security of a privacy-focused communication system whose security model and limits are documented publicly. The work takes place in a small, remote European team that records threat models and technical decisions, and expects product changes and security claims to remain aligned. The available role description gives no specific security specialty or experience level, so the scope should be clarified through discussion.

Responsibilities - Contribute security expertise to a communication product designed around privacy and protected messaging. - Engage with documented threat models, security decisions, and technical trade-offs. - Help ensure engineering changes are reflected in the documentation describing product security and capabilities. - Work through technical decisions in a written, reviewable process with the team.

Requirements - The available role description does not specify required security experience, tools, certifications, or technical qualifications. Be ready to describe relevant security work and areas of expertise during the hiring process.

Benefits and work setup - Remote work across Europe, with a few shared hours of overlap each day. - Written-first collaboration, with no employee monitoring software or work analytics. - The selection process includes an initial conversation, a short practical task or review of previous work, and discussions with future teammates. Applications are read by a person.
