Description

Mindrift is looking for skilled AI Workflow Engineers to join the Tendem project (https://tendem.ai/) and build intelligent automation systems powered by LLMs within our hybrid AI + human environment. In this role, as an AI Pilot – that’s how we refer to this position at Mindrift – you’ll collaborate with Tendem Agents that handle repetitive tasks, while you provide structured thinking, prompt engineering expertise, and quality control to deliver scalable and reliable AI-driven workflows. This part-time remote opportunity is ideal for professionals with hands-on experience in LLM integrations, prompt design, and AI-powered automation systems. What We Do The Mindrift platform connects specialists with AI projects from major tech innovators. Our mission is to unlock the potential of Generative AI by tapping into real-world expertise from across the globe. About the Role This is a freelance role for a Tendem project. As an AI Workflow Engineer, you'll design, build, and optimize workflows that integrate LLM APIs, creating scalable systems for content generation, communication, and automation. Key Responsibilities Design and evaluate workflows integrating LLM APIs (OpenAI, Claude, Gemini or similar). Build and optimize AI-powered automation systems for content generation, enrichment, and communication. Develop and refine prompt frameworks for consistent, high-quality outputs across workflows. Create systems for personalized automated outreach (email, messaging flows, lead enrichment). Structure and preprocess data to ensure stable model behavior and reliable outputs. Analyze and improve AI-driven pipelines for scalability, efficiency, and accuracy. Compensation On this project, contributors can earn up to $50 per hour equivalent, depending on their level and pace of contribution. Compensation varies across projects depending on scope, complexity, and required expertise. Please note that other projects on the platform may offer different earning levels based on their requirements. At least 3 years of relevant experience in AI automation, prompt engineering, workflow development, or software development (required). Bachelor's or Master’s Degree in Computer Science, Engineering, Data Science, Linguistics, or related fields is a plus. Strong experience working with LLM APIs (OpenAI, Claude, Gemini or similar) and integrating them into workflows. Proven ability to design prompt systems, chaining logic, and output optimization strategies. Solid background in API integrations, automation platforms, and multi-step AI pipelines. Experience structuring and preprocessing data for consistent AI performance (inputs/outputs, formatting, validation). Demonstrated experience building scalable AI-powered systems for real-world applications. Experience with personalization logic and dynamic content generation at scale. Strong understanding of LLM limitations (hallucinations, bias, context handling) and mitigation techniques. Experience integrating AI into outreach, analytics, or content automation pipelines. Strong attention to detail and commitment to output quality and consistency. Self-directed work ethic with the ability to troubleshoot and optimize AI systems independently. Portfolio or examples of AI workflows, prompt systems, or automation projects is a plus. English proficiency: Upper-intermediate (B2) or above (required). Why this freelance opportunity might be a great fit for you? Work fully remote on your own schedule with just a laptop and stable internet connection. Gain hands-on experience in a unique hybrid environment where human expertise and AI agents collaborate seamlessly — a distinctive skill set in a rapidly growing field. Participate in performance-based bonus programs that reward high-quality work and consistent delivery.
