Our founders, Shadi Bitar and Ninos Malki, came to Sweden from Syria when they were kids. Books became their compass, guiding them through the maze of life, and helping them shape their destinies in a new world.
Their dream was bold: What if they could unlock the world of books for everyone, making knowledge and inspiration accessible to all? Fast forward a few years, and the tale of Nextory was born.
At Nextory, we've crafted a revolutionary monthly subscription that empowers our users to devour books like never before, be it through reading or listening. It's not just a product; it's a passport to endless adventure and enlightenment.
WHY THIS ROLE MATTERS
We're scaling our AI capabilities to help millions of users find their next favorite book. To do that, we need someone to help build the infrastructure behind:
Personalized recommendations
AI librarian, our multi-agentic book recommender with chat interface
Semantic search with LLMs and vector retrieval
This isn't just about training models - it's about designing systems that deliver them reliably, efficiently and at scale.
WHAT YOU WILL DO
Ship ML-powered features to production with real user impact
Diagnose and triage issues: analyze logs, core dumps, and diagnostic data to identify root causes and drive timely resolutions.
Build and scale ML infrastructure on Google Cloud Platform (Vertex AI, BigQuery, GCS)
Develop production-quality Python services to serve models across chat, search, and recommendation systems
Strong experience with Google Cloud's Python SDKs, with a preference for deep familiarity with Vertex AI service
Implement MLOps practices including model versioning, drift detection, and evaluation tooling
Drive CI/CD, observability, and automation for ML workflows
Ensure model serving is low-latency, scalable, and cost-efficient
OUR STACK
Languages: Python, SQL
Cloud & MLOps: GCP (Vertex AI, BigQuery), Vertex AI Pipelines
Search & Retrieval: Vertex AI Search
Infra & Observability: Docker, Kubernetes, Terraform, GCP Monitoring

Proficient in Python, with experience deploying cloud-native ML systems (preferably GCP + Vertex AI)
Deep experience with end-to-end ML pipelines (training, serving, evaluation) and model serving via REST APIs
Strong command of Kubernetes, CI/CD, and infrastructure as code
Able to mentor engineers, perform code reviews, and drive architectural decisions
Comfortable with SQL and working with large datasets
Experience managing large-scale pipelines with solid observability practices
Strong problem-solving and communication skills; thrives in iterative, fast-paced environments
