Job posted: September 12, 2025

Location: Americas (North, Central and South America)

Zapier is hiring a Staff Applied AI Engineer for our Agents team to make agentic automation actually useful at scale. You’ll shape how our Agents plan, reason, remember, and safely take action through 8,000+ integrations—with enterprise-grade reliability. This isn’t a labs playground. Agents is customer-facing and revenue-impacting. If you like shipping systems that thousands of teams rely on—not just demos—you’ll thrive here.

Agents @ Zapier: One of our most ambitious bets—an AI assistant that helps users get work done across thousands of apps, at your finger tips, or as you sleep, and all of it easy enough to build in the space between one meeting and the next. You’ll work on reasoning, integrations, and the interface that lets users delegate with natural language. We move fast, but we harden what we ship.

Why this is different (and exciting)

• Actions are solved here: Everyone’s building agents; few can make them do things while you sleep. Zapier’s native connection to 8,000+ apps gives your agent real superpowers on day one.

• Immediate impact & distribution: Ship improvements that land in real customer environments quickly—across SMB to enterprise—then iterate with telemetry, not vibes.

• Hard problems, not hype: Planning & tool selection, grounding & evals, safety & governance, memory models, latency/cost tradeoffs—at production scale.

• Autonomy with responsibility: Your decisions shape product strategy, not just implementation details.

• Pragmatic AI culture: We explore new things as they develop and push the boundaries of agentic ability and UX, but we know when to lock down, standardize, and scale. Reliability > novelty when customers depend on it.

About You

• Proven engineering impact: You’ve driven outcomes in complex, cloud-based systems used by real customers. Bonus: you’ve helped win or expand enterprise deals—leading POCs, navigating security/compliance reviews, or shaping product requirements to land enterprise adoption. Many strong candidates for our Staff+ role have 10+ years’ experience. We hire for impact and capability, not years.

• LLM expertise: You have at least 2 years or equivalent depth of hands-on work with large language models in production, including user-facing products leveraging agent architectures. You are familiar with transformer networks, attention mechanisms, and their role in generating responses, function calls, and other complex tasks.

• Evaluation & retrieval systems: You have direct experience deploying evaluation frameworks for LLMs (performance, reliability, bias) and building Retrieval-Augmented Generation (RAG) systems. You have nuanced perspectives and experience with indexing/chunking strategies, semantic search, and vector databases, and how they differ from traditional retrieval methods.

• Builder first: You lead through hands-on contribution—pairing with product teams, unblocking adoption, modeling best practices, and shipping. You execute, not just advise.

• Pragmatic judgment over novelty: You separate signal from hype. You’re comfortable saying “not ready for production” (and explaining why), and you partner with product to decide when to keep exploring vs. when to lock down, standardize, and scale—using results from evals, user impact, and clear cost/latency tradeoffs.

• You design for scale and ambiguity. You can design systems and solutions in complex, high-scale environments—where priorities are fluid and ambiguity is the norm.

• Skilled communicator: You’re known for moving fluidly between pair programming, cross functional problem-solving, and customer discovery. You evaluate long vs. short-term solutions through the lens of speed to impact and cohesion of customer experience. You form trusting relationships and know how to bring others with you.

• You are an AI power user. You proactively embrace AI as a core part of your engineering toolkit and are excited to explore new ways it can accelerate learning, development, and operations. You don’t just use AI—you advocate for it, sharing your workflows and helping others level up.

Things You’ll Do

• Make Zapier Agents the #1 way to get real work done with AI: A year from now, Agents is the obvious choice—and you’ve delivered features, spotted differentiation opportunities, advised on product strategy, and up-leveled how our teams and customers build with Agents.

• Shape AI & Agents strategy: Stay close to the AI ecosystem, filter hype, and bring the right insights in-house for targeted experiments with crisp success criteria. You’ll scout high-leverage opportunities, define how planning and tool integrations show up in the user experience, and set clear explore-vs-harden guardrails—including making the call when something isn’t production-ready.

• Drive technical oversight: You’ll provide oversight for agent initiatives within and adjacent to Agents, ensuring we scale responsibly (security, privacy, reliability) while keeping velocity high. You’ll help Zapier adapt to a growing surface area without losing coherence.

• Advance agent architecture & developer experience: You’ll bring deep AI expertise to the Staff Engineer group, collaborate with Principal Engineers on company-level direction.

• Build data-driven systems: You’ll design feedback loops and evaluation suites that capture real usage, synthesize core use cases, and improve grounding, tool-use success, prompting strategies, and model choice—balancing quality, latency, and cost.

• Integrate and innovate (pragmatically): You’ll explore emerging agent capabilities and the ecosystem around them, then make crisp go/no-go calls and turn the right bets into durable product and platform wins.

• Collaborate and teach: You’ll mentor engineers, codify practical agent patterns, and help teams and customers understand where Agents fits in their broader AI transformation—multiplying impact beyond your immediate team.
