🚀 About DoNexus

We are DoNexus from Munich and we build AI agents for property management companies.

Our mission: to solve staff shortages in property management with AI by developing digital employees for management companies.

DoNexus was founded by Daniel Parak (Daniel Parak | LinkedIn) and Zeno Woywood (Zeno Woywood | LinkedIn) in March 2025. In the first 7 months, we generated six-figure revenue, brought our first investors on board and are now ready to take the market by storm together with you!

🎯 Your Mission

You bring consistency and reliability in our systems by testing frontend / backend interactions, write End-to-End test and ensure the quality of our AI.

What you’ll do:

• You test our systems end-to-end and ensure that frontend, backend and AI agents work reliably together.
• You spot silent and logical AI failures, evaluate response quality and think in real customer scenarios.
• You build and improve automated tests (Playwright, Jest, Pytest) to increase coverage and prevent regressions.
• You run manual tests, uncover edge cases and make sure only stable features reach our customers.
• You turn findings into clear bug reports (or fix them) and work closely with the team to steadily raise product quality.

Our TechStack:

Frontend: React/TypeScript · Backend: serverless Node.js · Agents/LLM: Python · Infra: Vercel · DB: Supabase (Postgres + Vector) · Testing: Playwright, Jest, Pytest

You don’t need to know everything – learning velocity is what counts.
