Job description
We are a European deep-tech leader in the quantum and AI space, supported by major global strategic investors. Our mission involves technology that is already transforming AI deployment worldwide, notably by compressing large language models by up to 95% without accuracy loss and reducing inference costs by 50-80%. You will be part of a team working on cutting-edge solutions that aim to make AI faster, greener, and more accessible.
Requirements

- Strong understanding of RESTful API or gRPC design, versioning, and performance optimization.
- Experience with Docker and Kubernetes for deploying scalable services.
- Solid understanding of relational databases (PostgreSQL/MySQL) and schema design.
- Proficiency with Git, testing frameworks, and CI/CD pipelines.
- A product-oriented mindset, able to turn R&D scripts or prototypes into stable, usable APIs or microservices.
Preferred Qualifications
- Experience with ML workflow orchestration (Flyte, Airflow, MLflow, or Kubeflow).
- Exposure to LLM inference/deployment tools (vLLM, Hugging Face Hub, NVIDIA NIM, or Triton).
- Familiarity with message queues or event-driven architectures (Kafka, NATS, RabbitMQ).
- Understanding of observability tooling (Prometheus, Grafana, OpenTelemetry).
