We are looking for a senior machine learning and java engineer to join our development team. You'll work on building and improving our AI systems that process and analyse real-time data streams from various sources including social media, traditional media, and customer feedback channels.

The role involves developing and maintaining machine learning models that work alongside our crowdsourcing platform to provide intelligent data analysis and insights to our clients. You'll be working with real-time data processing, building scalable ML solutions, and implementing efficient data storage and retrieval systems. These are mostly simple classification tasks.

Our tech stack includes:

• Modern JavaScript frameworks (React, Vue.js)
• Python for some portions of our ML stack

WHAT WE’RE LOOKING FOR

• Strong experience in machine learning and AI systems
• Solid backend development experience with Java
• Someone who can run tests and maintain code
• Experience with LLM prompting
• Experience delivering projects from idea to production
• A curious, always learning personality
• Strong communication skills and ability to work with cross-functional teams
• Problem-solving skills and proactive attitude
• Regarding AI and ML: we are looking for a domain expert but not a domain owner. Other members of our team will be working on ML and ML-adjacent projects, and you yourself will sometimes be working on non-ML projects.

We have a culture that encourages curiosity, innovation an
