[Hiring] Applied AI Engineer @Pinecone

Role Description

We're looking for an Applied AI Engineer who loves building real applications with AI. You'll work across the stack, from backend services and retrieval pipelines to APIs and user-facing applications, turning new AI capabilities into working solutions. This is a hands-on engineering role for someone who enjoys moving quickly, experimenting with emerging technologies, and owning projects from initial idea to production.

You'll work closely with our engineering and product teams, as well as customers and partners, to explore new use cases, build reference applications, and demonstrate what's possible with Pinecone's technology.

Responsibilities

• Design, build, and ship end-to-end AI applications using Pinecone’s retrieval and knowledge infrastructure.
• Develop full-stack solutions spanning frontend interfaces, backend services, APIs, data pipelines, and LLM integration.
• Build reference applications, integrations, and reusable components that help developers and customers adopt Pinecone.
• Experiment with emerging AI patterns, including RAG, agents, tool use, context engineering, and agent memory.
• Work with customers, partners, and internal teams to understand real-world problems and translate them into working software.
• Evaluate and improve the quality, reliability, latency, and cost of AI-powered applications.
• Share technical insights and best practices through code, examples, and technical content.
• Bring learnings from building applications back into Pinecone’s product and engineering teams.

Qualifications

• Strong software engineering background with experience designing, building, and shipping production applications.
• Proficiency in Python and/or TypeScript, including modern backend frameworks and frontend technologies such as React or Next.js.
• Experience building APIs, integrating external services, and working with databases and cloud infrastructure.
• Hands-on experience building applications using LLMs, embeddings, vector databases, or retrieval-augmented generation.
• Familiarity with modern AI development tools, frameworks, and APIs.
• Understanding of the practical challenges of building AI applications, including retrieval quality, evaluation, latency, reliability, and cost.
• Curiosity about emerging patterns in agentic applications, context management, and AI-driven workflows.
• A builder's mindset: you enjoy writing code, experimenting, and getting working software into users’ hands.
• Comfortable working with ambiguous requirements and making pragmatic technical decisions.
• Ability to communicate technical ideas clearly to engineers, customers, and other stakeholders.
• Comfortable moving between rapid prototypes and production-quality implementations.
• Interest in understanding how developers and customers use the technology and translating that feedback into better solutions.

Bonus Points

• Experience with Pinecone or other vector databases and search technologies.
• Experience building agentic applications, agent memory systems, or complex RAG pipelines.
• Contributions to open-source projects, developer tools, or technical communities.
• Experience working directly with customers on technical projects.
• Experience deploying and operating AI applications in production.

Benefits

• Comprehensive health coverage including medical, dental, vision, and mental health resources.
• 401(k) Plan.
• Equity award.
• Flexible time off.
• Paid parental leave.
• Annual Company Retreat.
• WFH Equipment Stipend.
• Benefits and eligibility may vary by country of employment.
