About the job
We are looking for a 3rd team member to focus on building the product. You are about to finish your studies or have already graduated. Your last university degree is no longer than 5 years ago. You combine product and engineering experience and enjoy trying out ideas through your own projects. At Thellma, you will create hypotheses, build small experiments, learn and ship features. You will own the product pipeline, from gathering user feedback to managing our backlog. Based on our common insights about how legal teams work and think, we will work on product strategy and roadmap together. You’ll work alongside the founders in our office in Berlin Charlottenburg, in the midst of a community of ambitious AI start-ups. You’ll ship the products that will make expert legal knowledge affordable to smaller companies. You will change how legal teams think about product compliance and drive innovation in the legal industry.
Why you should apply now ● Build with the best: Collaborate with a software engineer from Silicon Valley with 15+years experience, who is eager to invest in your personal growth. Ex-mentees now work at top companies like Google, Asana, and Shopify. ● Unbounded impact: Own and scale our product development processes. Of course, you’ll get unlimited access to LLMs! ● Shape who we are: Every day, we will make Thellma a reality together. You will help decide what we build next and how. You’ll see how customers shape development and how technical and business decisions affect our growth.
