Software Engineer (Medior / Senior)
SmartCat is an AI-driven company that works on hard data problems. We're selective about the projects we take on, and we care that the work actually matters. We're looking for a backend engineer, Medior or Senior, to help build and run large event-driven systems that have to stay reliable under heavy load. Most of the work is microservices that move a lot of data around.
What you'll do:
🌸Build and run microservices that handle large volumes of data.
🌸Connect services with Kafka and Avro, and keep the schema contracts between them clean.
🌸Work with different data storage (Cassandra, ElasticSearch, Postgress, Redis….) and handle schema changes without breaking things.
🌸Keep services observable, and take the manual work out of testing and deployment.
🌸As a Senior: own the architecture decisions and mentor the rest of the team.
What we're looking for:
💦3+ years for Medior, 5+ for Senior, mostly with Java and Spring Boot. Python or Go is a plus.
💦You've built distributed systems and are comfortable with microservices and event-driven design.
💦Hands-on with Kafka (Kafka Streams is a plus) and Avro with a schema registry.
💦Good with PostgreSQL and SQL. Experience with jOOQ, Flyway, or reactive access (R2DBC / Project Reactor) is a real plus.
💦You care whether things work in production: metrics, tracing and logging (we use OpenTelemetry, Micrometer and Prometheus), and fallback patterns like Resilience4j.
💦You know Docker and Kubernetes. We run on-prem and on OCI; cloud experience (AWS, Azure, GCP) is welcome too.
💦Security matters to you. Pen testing or red-team experience is a big plus.
💦You write tests, unit and integration (we use Testcontainers).
