Software Developer

We are looking for an experienced Full Stack Developer to take ownership of our app ecosystem. You will be responsible for identifying, debugging, and resolving both frontend UI/UX issues and complex backend infrastructure challenges.

Because we leverage cutting-edge AI IDEs (Google Antigravity) for rapid development, you won’t just be writing code line-by-line. You will act as a system architect-reviewing AI-generated artifacts, enforcing strict coding formats, and ensuring our database and API endpoints scale securely.

Key Responsibilities

Dual-App Management: Maintain, debug, and optimize both the Ayonic Customer App and the Ayonic Provider App.

Backend & API: Architect and troubleshoot backend logic, database schemas, and API endpoints (JSON format, strict state management).

Payment Integration: Securely manage our Stripe payment flows and commission-tracking logic, strictly adhering to our mock-key environment security protocols.

AI Collaboration: Work directly with our Google Antigravity AI agents, writing clear Markdown ( .md ) rule files and reviewing task artifacts before execution.

Security & Compliance: Ensure all data handling complies with GDPR and German marketplace regulations, preventing data leaks or prompt injection vulnerabilities.

Do you have experience in TypeScript?, Proven Experience: Extensive background in Full Stack development, specifically building and maintaining mobile applications and robust backends.

Tech Stack Mastery: Deep understanding of modern frameworks (e.g., React Native, Node.js, TypeScript) and real-time infrastructure (e.g., Socket.io).

Architectural Mindset: Ability to design secure database structures and API routes without needing constant hand-holding.

Security First: Strong understanding of environment variable management, .gitignore rules, and API key protection.

Adaptability: A willingness to embrace “agent-first” development workflows and code alongside autonomous AI tools.

Ayonic is a fast-growing, dual-app digital marketplace disrupting the German gig economy. We connect customers with professional, independent service providers-ranging from certified financial advisors to professional cleaning services. We operate a highly scalable platform consisting of a Customer App, a Provider App, and a robust backend that handles real-time lead generation, matchmaking, and commission structures.
