MAP Policy Partners is a Beacon Software portfolio company and a leader in MAP (Minimum Advertised Price) enforcement automation. With over 15 years of industry experience, we've engineered a streamlined, automated solution for MAP monitoring and enforcement, built to detect, investigate, and act on violations across millions of online sellers.

We are looking for a hands-on Tech Lead to serve as the sole developer in our small but growing software company. This is a unique opportunity to take full ownership of our technical stack, drive product development, and shape the direction of our platform. Our product relies heavily on web scraping, and we're seeking someone who can bring both technical expertise and pragmatic problem-solving. Given the lean nature of our team, this role requires someone who thrives on autonomy, can wear many hats, and leverages AI-assisted development tools to accelerate delivery and efficiency.

• Document systems, processes, and technical decisions for long-term maintainability

• 5+ years of professional software development experience, with strong expertise in Ruby on Rails (must-have)
• Background in SaaS product development with strong Business and Product foundations—you will be joining a lean team and your opinion in all matters of the business, especially Product, will be very valuable
• Ability to work independently as the sole developer in the company, balancing short-term needs with long-term maintainability
• Experience managing and scaling a Rails monolith in production environments
• Demonstrated experience with web scraping tools and techniques (e.g., FireCrawl, BrightData, custom scrapers)
• Familiarity with Heroku or similar PaaS platforms

• Comfortable leveraging AI coding assistants and modern developer productivity tools
• Strong debugging, problem-solving, and performance optimization skills
• Experience with Stimulus or lightweight frontend approaches optimized for solo development
