Our client is building something ambitious and we’re looking for a Senior Full Stack Developer (Solid.js + Rust) to help them create it from the ground up. You’ll be one of the first engineers in their Vienna founding team, working closely with our US-based core team to bring an AI-powered SaaS platform to

- Integrate AI capabilities (LLMs, agents) into both backend systems and the frontend experience
- Influence architecture and technical decisions from day one
- Work independently while syncing regularly with the Vienna and US-based teams
- Participate in occasional in-person meetings in Vienna

- Strong expertise in Rust and Solid.js (or strong experience in another modern frontend framework like React)
- Solid understanding of PostgreSQL and backend best practices
- Proven experience building and shipping full stack applications end-to-end
- Excellent communication skills in English and German
- Self-motivated, proactive, and excited about early-stage building
