Senior Backend Engineer

The Search team builds Nimble's AI-native search infrastructure - the core engine that enables AI agents to access the web and retrieve structured, high-quality data at scale. This is one of the most critical and fast-moving areas of the product.

We're hiring a backend engineer to help design, build, and improve the systems that power it.

• Build and optimize the search pipeline end-to-end - from query processing and retrieval to ranking and structured output.
• Own performance benchmarks and quality evals for the search system. Use data to drive continuous improvement in accuracy, latency, and coverage.
• Design the backend infrastructure and APIs that power AI search for our customers.
• Work closely with AI researchers and ML engineers to bring new capabilities from research to production.
• Bring product sense - understand how customers use the search API and what they actually need.

• 8+ years of backend experience, with scale experience - you've built systems that serve real external users and know how to keep them running, gained at large-scale web companies or fast-growing, successful startups.
• 2+ years of hands-on experience in an agentic product team - you've shipped meaningful LLM-powered products in production, not just experimented.
• Familiarity with modern search and retrieval patterns: web crawling, ranking, embedding-based retrieval, structured extraction.
• Strong instincts for performance optimization, benchmarking, and data quality.
• Distributed-systems experience: queues, caching, scalability, and reliability at scale.

Advantage

• Experience with LLM-powered pipelines or agentic systems.
• Familiarity with AI/ML concepts: embeddings, retrieval, model evaluation.

Nimble is the real-time web search platform built for enterprise accuracy, completeness, and trust. We run Web Search Agents that actively navigate live websites using real browsers and reasoning, turning the public web into governed, decision-grade data for AI systems and high-stakes business use.

Unlike index-based “AI search” tools or brittle legacy scraping, Nimble makes the live web queryable on demand, delivering structured outputs that teams can verify and rely on. Our platform powers use cases where correctness matters: financial due diligence, real-time pricing and promotions, market intelligence, and AI systems that depend on fresh, complete data.

Trusted by leading enterprises like Home Depot, Uber, and Coca-Cola and backed by top-tier investors, Nimble sits at the intersection of AI, automation, and real-time web intelligence.

As demand accelerates across AI, LLMs, and data-driven decisioning, we’re scaling quickly and looking for high-energy, driven teammates who thrive in fast-moving environments and want to help define a new category.

Why join Nimble?

• Work on a deeply technical platform powering real-time AI and enterprise decisions
• Help define the future of Web Search Agents and live web intelligence
• Build alongside a sharp, mission-driven team that moves fast, ships often, and takes ownership
