The core of your role is making Langfuse fast and affordable at scale: owning the ingestion pipeline, optimizing ClickHouse data models and queries so dashboards load instantly, and building the backend abstractions that let product engineers ship data-heavy features without reinventing the plumbing each time. You will also make sure Langfuse runs everywhere.…

  • Title alignment (16%). Whether the role is actually pitched at your field rather than adjacent to it.
  • Freshness and filters (18%). Newer postings, your work type and your target region all move the score.
