• Founder Voice: Help the founders express their ideas in their own voices and build a consistent presence across founder and company channels.

Your Profile

• You take responsibility for finishing what you start, raise a concern when a draft is wrong and use direct feedback to improve your work.
• You write excellent English, with samples that show independent thought and careful revision. Your best work might come from a student publication, an internship, a personal blog or a research project.
• You're a recent graduate or have up to three years of experience. Previous full-time communications experience is not required.
• You're curious about technology and can research, check facts and explain complex subjects without losing what matters.
• You have good editorial judgement and notice unsupported claims, empty phrases and details that change the meaning of a sentence.
• You're based in Munich or willing to relocate. Strong German is a plus, particularly for work with German customers and institutions. Given the nature of SE3's work in the defence sector, candidates must be eligible to work on defence-related projects and, where required, obtain the relevant security clearance.

Our Process

• Intro Call (30 min): Let's get to know each other.
• Paid Writing Exercise: Turn a technical interview we supply into a short post and a longer explanation, then revise both after our feedback.
• Writing Interview (1 hr): We discuss your writing samples, how you researched them and what you contributed to each.
• Team Dinner / Lunch: Meet the team and see whether it is a strong fit on both sides.

Please include two or three pieces of writing with your application, explain what you personally contributed to each and tell us why this work interests you. If you have an early draft and a much improved version, we would be glad to see both.
