About Us

Parallel is a web infrastructure company. Our products are used by leading businesses in sales, marketing, insurance, and coding to build best-in-class AI agents with flexible and powerful programmatic access to the web. We've raised $230 million from Kleiner Perkins, Sequoia, Index Ventures, Spark Capital, Khosla Ventures, First Round, and Terrain to build the web for AIs. We're currently valued at $2 billion and we're forming a world-class team of engineers, designers, marketers, sellers, researchers, and operational experts to achieve our mission.

Job

You will own the multi-stage ranking pipeline that narrows a web-scale set of candidates down to the handful of best passages for a query, spending the least compute necessary to do it well. You will push precision and recall across fast candidate retrieval, lightweight first-pass ranking, and heavier neural reranking, decide how much compute each query deserves, and grade everything on real usage outcomes rather than offline proxies.

You

• Have deep intuition for relevance, feature engineering, and the trade-offs between quality, latency, and cost.
• Think rigorously about how ranking, retrieval, and agent behavior inform one another, and how to train models that serve all three.
• Care about your research being applied to product and systems that millions use.

Life at Parallel

• The team works fully in-person, between our Palo Alto HQ and San Francisco office.
• We’re a flat, talent-dense organization dedicated to solving technical and creative problems.

Values

• Own customer impact: It’s on us to ensure real-world outcomes for our customers.

• Accelerate change: Ship fast, adapt faster, and move frontier ideas into production.
