We offer you an influential role in a fast-growing company:

HeyJobs is seeking a highly motivated AI Builder/Engineer to support the CEO and a small dedicated team in launching and scaling our newest AI recruiting product.

We are running a Proof of Concept (PoC) during Q1-Q2 2026 for a potential new and exciting product/business line at HeyJobs, leveraging our existing infrastructure and assets, but utilizing new technologies to accelerate it.

The challenge: Prove that 90%+ of a complex, multi-step service workflow can be automated using AI- faster and cheaper than human experts.

The setup: A small, entrepreneurial team (founder, PM, domain expert, sales, 2 working students, and you) working like a startup within HeyJobs. Low hierarchy, high autonomy, fast iteration.

Your job is to make it technically real.

How you can contribute to HeyJobs

• As the technical lead, you will own and implement the tech that makes this PoC reality - fast
• Drive technical decisions and implementation from 0 to working PoC system
• Leverage SaaS tools, AI APIs, and workflow automation (Langdock Workflows, n8n, Zapier, Make.com, LangFlow) to iterate rapidly rather than building everything from scratch
• Work across the full stack: LLMs/AI APIs, workflow automation, integrations, simple interfaces, Python scripting
• Pragmatically interface with existing HeyJobs infrastructure to leverage data, tools, and capabilities where beneficial (our stack is Ruby on Rails, AWS, Python, React)
• Make product-technical trade-offs and propose creative solutions when hitting roadblocks
• Work very closely with founder, PM, domain expert, and sales—and take over work as needed to ship
• Document what works, what doesn't, and define the path to 90%+ automation
