Lastly, at Synthesio, we have a strong tech culture. This means the teams have an important role. Each squad is empowered, owns together the success of the projects, and chooses their deliverables and their timelines.

Our department

The Synthesio product engineering department is focused on data provisioning, enrichment, and exploitation.

Synthesio crawls numerous public consumer data footprints including social, reviews and ratings, survey, search, and press data, representing more than 80M new documents per day. Each document is then analyzed and enriched using custom NLP and image recognition models developed by our data scientists. All this data is stored in databases and can be accessed by our customers via our dashboarding solution or our APIs.

Job Description

Our back-end stack: Go, Python, JS, React, MySQL, Elasticsearch, Cassandra, Kafka, Gitlab, Docker, Ansible.

Our platform uses a microservice architecture containing 200+ microservices, most of them written in Go and using Kafka or HTTP to communicate.

1 PB+ Elasticsearch, 750TB+ MySQL clusters, 150 TB+ Scylla DB, and 250TB+ of Kafka.

Example projects we’ve worked on:

Add vector search capabilities.
Data usage tracking to enable cost monitoring and tailored billing.
Implement new crawlers to retrieve documents from more diverse sources.
Revamp of the alerting system for increased stability and additional functionalities.
Custom AI enrichments for clients to further personalize their experience and usage.
