Descripción de la vacante

Semrush is seeking an experienced engineer to build high-quality Python services and scalable data pipelines. You will collaborate with Data Scientists to create advanced ML/AI systems while designing cost-efficient data workflows over PostgreSQL, BigQuery, ClickHouse, and GCS.

You will also orchestrate workflows with Temporal, deploy on Kubernetes/GCP, and ensure reliability and observability at scale. A strong focus on CI/CD, code quality, and data integrity is expected in this fast-paced team.

Formación

• 5+ years of strong software engineering fundamentals - clean code and solid testing practices.
• Strong Python development skills.
• Experience with Docker; Kubernetes is a plus.

• Design and operate cost-effective data pipelines over PostgreSQL, BigQuery, ClickHouse, and GCS - including schema migrations (Alembic) and data quality checks.
• Integrate and optimize LLM workloads end-to-end: multi-provider routing, cost monitoring, fallbacks, and continuous evaluation.
• Orchestrate workflows with Temporal and deploy on Kubernetes/GCP (Docker, Pub/Sub, KMS, IAM).
• Own reliability and observability - Grafana, Prometheus, Sentry, Langfuse - and keep pipelines healthy at scale.
• Maintain CI/CD pipelines for automated, safe deployments (including DB migrations).
