Job description

  • Build high-quality, scalable, maintainable Python services and data pipelines.
  • Collaborate with Data Scientists to build cutting-edge ML/AI systems.
  • 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).
  • Drive code quality through clean code, testing, pair programming, code reviews, and knowledge sharing., Torch team is an engineering team building LLM-powered products for Content and brand intelligence. We own two domains:
  • AIO (Brand presence, serenity, prompt tracking) - measuring and improving how brands show up across AI/LLM answers (ChatGPT, Gemini, Perplexity, Google AI Overview). Think "SEO analytics for the AI-search era," without relying on classic Google rankings.
  • Content - AI-driven content scoring, SEO/GEO guidelines, and content-generation suggestions. We run large-scale data pipelines that turn raw LLM/SERP responses into trustworthy brand-visibility metrics. Cost-efficiency at scale is a core engineering challenge - we continuously benchmark and switch between LLM providers (OpenAI, Gemini, Mistral, Grok, Nebius, Claude) to balance quality and spend.
