Full-time, Contractor
Posted 19 days ago
Freelance AI Growth Engineer & Creative Technologist
Company: PA-AI
Location: Southern California
Collaboration: Periodic in-person meetings at RKS Design in Thousand Oaks
Engagement: Initial paid 30-day independent contractor sprint
Potential: Continuing freelance engagement or transition to a full-time role based on results and mutual fit
About PA-AI
PA-AI is a human-centered artificial intelligence platform that helps organizations make better product, innovation, business, and marketing decisions.
The platform combines advanced AI with a deeper understanding of human behavior, emotion, perception, aspiration, and trust. It helps teams identify opportunities, evaluate ideas, reduce risk, and create products, services, brands, and experiences that people genuinely value.
PA-AI is built on Psycho-Aesthetics®, a proprietary methodology developed and refined by RKS Design through more than 45 years of innovation and product-development work.
The Opportunity
You will design and build an AI-powered growth system that identifies relevant conversations, creates platform-specific content, activates communities, tests messaging, and converts awareness into qualified PA-AI users.
We are not looking for someone who simply schedules posts. We want someone who can build the machine behind the campaign.
The right candidate will know how to combine existing AI tools, SaaS platforms, content applications, CRM systems, analytics products, and automation services into a coordinated growth workflow.
You will not be expected to build every component from scratch. You should be able to identify the best existing tools for each requirement, integrate them effectively, and add lightweight customization where necessary.
This may include using Claude and other AI-assisted development tools to create scripts, connect APIs, transform data, configure workflows, troubleshoot integrations, and develop small custom applications that close gaps between existing platforms.
The goal is not unnecessary custom software. The goal is a practical, measurable, maintainable system that produces results.
What You Will Build
How You Will Build It
You will use the most effective combination of existing and customized tools.
This may include:
You should be able to determine when to:
What We Are Looking For

How Success Will Be Measured
Success will be evaluated based on measurable growth and the quality of the system created, including:
Follower counts and impressions alone will not be considered sufficient measures of success.
Initial Engagement and Compensation
The engagement will begin with a paid 30-day discovery, build, and validation sprint.
During the sprint, the selected candidate will:
The anticipated project fee is $7,500 to $12,500, depending on the proposed scope, experience, deliverables, and demonstrated ability.
This is a project-based independent contractor engagement, not a monthly salary or guaranteed employment arrangement.
A continuing freelance engagement or transition to a full-time position may be considered based on measurable results, quality of execution, mutual fit, business needs, and the candidate’s ability to take ownership of the growth system.
Expected 30-Day Sprint Deliverables
Proposals should define clear deliverables, but the initial sprint is expected to produce:

Please Also Answer
Using PA-AI’s existing website, videos, thought leadership, reports, and platform capabilities, how would you design an initial system to generate qualified student and professional registrations?
Please address:
PA-AI is an equal-opportunity organization. We value different perspectives, backgrounds, experiences, and ways of thinking, and encourage qualified candidates from a wide range of disciplines to apply.
What We Are Looking For
A computer science, engineering, technical product, creative technology, growth, or entrepreneurial background is preferred, but demonstrated capability matters more than credentials.
