We’re now hiring a Remote Prompt Engineer based in the United States to help us accelerate the way we create, automate, and scale using the latest AI technologies. If you’re obsessed with AI tools, prompt writing, and building end-to-end automations that actually work, this is the opportunity for you.

If you’re obsessed with AI tools, prompt writing, and building end-to-end automations that actually work, this is the opportunity for you.

As our Prompt Engineer, you’ll be at the forefront of AI strategy and implementation. This role blends creative thinking, technical fluency, and marketing logic to deliver real-world results for both BluCactus and our clients. You will not just write prompts — you will build systems using AI.

This is a role for a builder, not just an operator.

• Design, test, and optimize advanced prompts for ChatGPT, Claude, and other LLMs
• Build and document reusable prompt libraries and GPT agents for daily use
• Create custom AI Agents that replace tasks like onboarding, reporting, appointment setting, HR screening, and more
• Work closely with our strategy, creative, and ads teams to integrate prompt workflows across departments.
• Research and summarize trends, competitors, and market insights using tools like Perplexity.ai
• Create dynamic video and content using AI avatar tools such as HeyGen and Photo AI
• Build no-code automations in Make.com and Zapier that streamline daily operations
• Document internal AI processes and maintain up-to-date SOPs and AI system maps
• Train internal team members on prompt usage, prompt chaining, and maintaining tone-of-voice consistency across AI outputs

We value outcomes over effort. That’s why we empower our Prompt Engineer with access to premium AI tools, strategic guidance, and a culture of experimentation.

We’re looking for someone with a unique mix of strategy, creativity, and execution.

• Proven experience designing and testing effective AI prompts
• Ability to create clear structure: role assignment, context, format, examples
• Deep understanding of prompt-based outputs for sales, marketing, HR, and outreach
• Strong written English — must be concise, persuasive, and on-brand
• Experience using Make or Zapier for end-to-end automations
• Demonstrated ability to build and maintain AI workflows, SOPs, and custom GPTs
• Ability to work independently and report clearly on project status and outcomes

• Past experience working in marketing agencies or with fashion/SaaS clients
• Experience creating or managing custom AI avatars and personalized video outreach
• Understanding of how to structure “AI employees” for departments like HR, Sales, and Admin
• Familiarity with AI content tools like Durable, Obviously.AI, Opus Clip, or AIO
• Based in the United States (Eastern or Central time preferred, but not required)

You’ll work directly with our CEO, project managers, and performance team leads. We run lean, fast-moving teams across 6+ countries and 4 time zones, and we’ve built a culture around clarity, ownership, and curiosity.

This role has direct impact — your AI systems will be used across internal projects and global client campaigns within weeks.

We’re not just another digital agency. We’re positioning ourselves to lead the AI marketing space — and we need a Prompt Engineer who’s ready to scale with us.

• 100% remote role, flexible hours within your time zone
• Competitive salary based on experience
• Performance-based bonuses and milestone incentives
• Access to advanced AI tools and training resources
• Fast-moving, results-driven, collaborative team
• Clear growth path into senior AI systems, automation, or leadership roles
• Opportunity to shape the agency’s internal AI operations and client offerings

At BluCactus, we value people who:

• Take initiative and seek solutions
• Think like entrepreneurs, not employees
• Communicate clearly and consistently
• Build and document, not just execute
• Stay on the pulse of AI innovation and aren’t afraid to experiment
