Texts are the fabric of the digital world. There’s so much information at our fingertips, but making sense of it efficiently is still very hard. Deepset's mission is to break this barrier, and empower any developer to harness powerful NLP pipelines to efficiently access and comprehend any kind of data. Our open-source project Haystack is already used all around the world and we set out to become the semantic layer in every enterprise tech stack.

In this position, you will join us as a software engineer with a dedicated focus on our SaaS platform and help us designing the core architecture for a fast, reliable, and enjoyable developer product. You will work in an interdisciplinary team of backend, frontend and DevOps folks. As we are building a product that no one has built before, you will need to crack some tough nuts around scalability, distributed systems, and user-friendly API design.

Examples: Reduce the latency of search requests; Integrate Ray for distribution of complex search pipelines; Implement a task queue with Celery; Design a REST Endpoint for the conversion of documents
