Who you are

• You have 7+ years of experience in software engineering, with at least 3 of those years dedicated to building distributed, scalable, cloud-based ML/AI systems in production environments
• You have strong communication skills, sound engineering judgment, and a track record of building reliable systems that other engineers depend on
• You have at least 2 years of experience in LLM Ops, ML Ops, or adjacent platform/infrastructure work
• You’re excited by problems like model access, inference reliability, observability, experiment management, evaluations, deployment workflows, governance, and production monitoring
• You have experience building shared services, internal platforms, or reusable developer tooling that enable other teams to move faster
• You enjoy creating strong abstractions, reducing duplication, and improving standards across an organization
• You have experience of working through the full lifecycle of building, testing, deploying, and scaling ML/ LLM architectures
• You can identify and document trade-offs made during the development of AI/ML systems. You also have experience building with cloud infrastructure technologies
• You love enabling others. You’re energized by building infrastructure and tooling that make product engineers and ML practitioners more effective
• You think deeply about developer experience and know that the best platforms are both powerful and easy to adopt
• You embody our values. At Zapier, our values are at the heart of how we work together and how we think about our customers. In our remote setting, they help develop trust and ensure we work and collaborate to democratize automation

What the job involves

• We’re thrilled to invite you to join Zapier’s AI Platform team as a Sr. Applied AI Engineer!
• As a key member of this team, you’ll help build and evolve the shared infrastructure that powers AI and ML development across Zapier
• The AI Platform team owns the common foundations that product and engineering teams rely on when building with machine learning and generative AI - including systems like our LLM proxy server, observability tooling, and ML Ops platform capabilities
• This is a highly leveraged role. Rather than building a single end-user feature, you’ll create the core systems, tooling, and standards that many teams use as their baseline for shipping intelligent products and internal AI-powered workflows
• You’ll work at the intersection of platform engineering, applied AI, and developer experience to make it easier for teams across Zapier to build with LLMs and ML systems in a scalable, secure, and production-ready way
• Your work will focus heavily on LLM Ops and ML Ops: improving how models are accessed, monitored, evaluated, deployed, governed, and operated in production. You’ll help define the paved road for teams building with AI at Zapier
• Build and evolve shared AI Platform capabilities that serve as the foundation for teams building with machine learning and generative AI across Zapier
• You will work mostly in TypeScript & Python. Experience isn’t strictly required, but it is a big plus. Comfort with typed languages and modern backend practices is a must
• Improve our LLM Ops and ML Ops capabilities, including observability, monitoring, evaluation, deployment workflows, and operational guardrails
• Design and implement systems that help teams measure and improve the performance, reliability, safety, and cost efficiency of AI-powered experiences
• Proactively identify tooling gaps and work across teams to standardize best practices for building, deploying, and monitoring AI-driven experiences
• Collaborate closely with engineers across product, infra, and data teams to ensure our AI components are reusable, well-documented, and easy to adopt company-wide
• Evaluate emerging tools, models, and patterns in the AI ecosystem, and help determine which ones should be incorporated into Zapier’s shared platform
