About us: Talent has no borders. Proxify's mission is to connect top developers around the world with the opportunities they deserve. So, it doesn't matter where you are; we are here to help you fast-track your independent career in the right direction. 🙂 Since our launch, Proxify's developers have successfully worked with 1200+ happy clients to build their products and growth features. 5000+ talented developers trust Proxify and its network to fulfill their dreams and objectives. Proxify is shaped by a global network of supportive, talented developers interested in remote full-time jobs. Our Glassdoor (4.5/5) and Trustpilot (4.8/5) ratings reflect the trust developers place in us and our commitment to our members' success. The Role: We are looking for a Senior AI Engineer to join one of our high-growth client teams to lead the development of next-generation autonomous systems. This is a backend-heavy fullstack role where you will be responsible for more than just simple prompt engineering. You will be architecting Agentic Workflows—systems that can reason, use tools, and execute complex coding tasks autonomously. The ideal candidate is a language-agnostic engineer who is obsessed with the Claude ecosystem and has hands-on experience building systems where AI agents interact with real-world data and codebases. You will bridge the gap between advanced LLM capabilities and robust, scalable backend production environments. What we are looking for: Deep expertise in Agentic Development. You should be comfortable building multi-agent systems, ReAct loops, and self-correcting workflows. Mastery of the Claude 3/3.5 family. You understand how to leverage Claude’s high reasoning capabilities and long context windows for complex logic. Experience building "AI-coding" features—using LLMs to generate, refactor, and test code programmatically within an application. Strong proficiency in at least one major backend language (Python, C#, or JavaScript/Node.js) and the ability to design the infrastructure (APIs, Webhooks, Databases) that supports AI agents. While backend-heavy, you are comfortable building the necessary frontend components (React/Vue) to allow users to interact with AI agents seamlessly. Extensive experience giving LLMs "tools"—designing clean API interfaces that agents can call to perform actions in the physical or digital world. Intermediate-advanced English level. Time zone: CET (+/- 3 hours). We are unable to consider applications from candidates in other time zones. Nice-to-Have: Experience with LangChain, LangGraph, or CrewAI. Knowledge of Vector Databases (Pinecone, Weaviate) and advanced RAG patterns. Familiarity with LLM Observability tools (LangSmith, Helicone) to debug agentic reasoning chains. Background in Software Engineering Fundamentals: You treat AI code like production code (CI/CD, Unit Testing, Version Control). Responsibilities: Design and deploy autonomous agents that can handle end-to-end tasks, specifically focusing on Claude-based coding agents. Build the scalable "brains" of the application, ensuring that AI reasoning is integrated into the core business logic. Refine system prompts and multi-shot examples to maximize Claude’s reasoning performance. Implement guardrails and validation layers to ensure that agentic outputs are safe, predictable, and high-quality. Work with Product and UX teams to define how "AI Agents" should feel and behave within the product interface. What we offer: Get paid, not played No more unreliable clients. Enjoy on-time monthly payments with flexible withdrawal options. Predictable project hours Enjoy a harmonious work-life balance with consistent 8-hour working days with clients. Flex days, so you can recharge Enjoy up to 24 flex days off per year without losing pay, for full-time positions found through Proxify.

关于我们：人才无国界。Proxify的使命是将全球顶尖开发者与他们应得的机会连接起来。所以，无论你身处何地，我们都会帮助你快速推进独立职业生涯，朝着正确的方向前进。🙂 自我们成立以来，Proxify的开发者已成功与1200多家满意的客户合作，构建他们的产品和增长功能。5000多名优秀开发者信任Proxify及其网络来实现他们的梦想和目标。Proxify由一个支持性强、才华横溢的全球开发者网络塑造，他们对远程全职工作充满兴趣。我们的Glassdoor（4.5/5）和Trustpilot（4.8/5）评分反映了开发者对我们的信任，以及我们对成员成功的承诺。

职位：我们正在寻找一名Senior AI Engineer加入我们的一个高增长客户团队，领导下一代自主系统的开发。这是一个以后端为主的全栈职位，你将负责的不仅仅是简单的prompt engineering。你将架构Agentic Workflows——能够推理、使用工具并自主执行复杂编码任务的系统。理想的候选人是语言无关的工程师，痴迷于Claude生态系统，并具有构建AI agents与真实世界数据和代码库交互系统的实操经验。你将弥合先进LLM能力与稳健、可扩展的后端生产环境之间的差距。

我们正在寻找：在Agentic Development方面具备深厚专业知识。你应当能够自如地构建多agent系统、ReAct loops和自我纠正工作流。精通Claude 3/3.5系列。你了解如何利用Claude的高推理能力和长上下文窗口来处理复杂逻辑。具有构建“AI-coding”功能的经验——在应用程序中以编程方式使用LLMs生成、重构和测试代码。至少精通一种主流后端语言（Python、C#或JavaScript/Node.js），并具备设计支持AI agents的基础设施（APIs、Webhooks、Databases）的能力。虽然以后端为主，但你也能自如构建必要的前端组件（React/Vue），以便用户与AI agents无缝交互。具有为LLMs提供“tools”的丰富经验——设计干净的API接口，使agents能够调用以在物理或数字世界中执行操作。中高级英语水平。时区：CET（+/- 3小时）。我们无法考虑其他时区的候选人申请。

加分项：具有LangChain、LangGraph或CrewAI经验。了解Vector Databases（Pinecone、Weaviate）和高级RAG模式。熟悉LLM Observability工具（LangSmith、Helicone），用于调试agentic reasoning chains。具备Software Engineering Fundamentals背景：你将AI代码视为生产代码（CI/CD、Unit Testing、Version Control）。

职责：设计并部署能够处理端到端任务的自主agents，特别聚焦于基于Claude的coding agents。构建应用程序可扩展的“brains”，确保AI reasoning集成到核心业务逻辑中。优化system prompts和multi-shot examples，以最大化Claude的推理性能。实施guardrails和validation layers，确保agentic输出安全、可预测且高质量。与Product和UX团队合作，定义“AI Agents”在产品界面中的感受和行为方式。

我们提供：获得报酬，而不是被玩弄。不再有不可靠的客户。享受按时月度付款和灵活提现选项。可预测的项目工时。通过与客户保持一致的8小时工作日，享受和谐的工作与生活平衡。Flex days，让你充电。对于通过Proxify找到的全职职位，每年可享受最多24天flex假期而不损失薪资。在尖端公司中获得加速职业发展的职位。在世界上最令人兴奋的公司中发现独家的长期远程职位。精心挑选的机会
