Description

About Tag Software Group

Tag Software Group is a team of experienced investors and operators dedicated to acquiring, improving, and growing mission-critical software companies serving small and medium-sized businesses (SMBs), large enterprises, and the public sector.

Founded as part of Valsoft Corporation, TAG offers a permanent home for software companies — we do not acquire businesses to resell them. Our priority is to build long-term partnerships that protect your legacy, your employees, and your customers.

Our in-house team ensures an efficient, transparent, and seller-friendly process, providing speed and certainty of closing. Once integrated into TAG, your company benefits from proven best practices, dedicated value-creation resources, and the broader ecosystem of our sister companies, including proprietary technologies such as ValPay and Sadie AI to help your business reach the next level.

Culture

Tag Software Group is much more than just a workplace — we are a team. When we say that people are our greatest asset, we truly mean it, and investing in them is our top priority.

We create an environment where employees feel the excitement of their first day on the job, every single day, fostering a culture of high performance and collaboration. We celebrate our achievements and take pride in them. We Dream Big, Stay Humble, and Stay Hungry.

The Opportunity

The AI Product Engineer plays an essential role in creating new AI-powered products, directly contributing to accelerating our technological evolution.

With an entrepreneurial mindset, this role focuses on rapid development, iterative experimentation, and delivering solutions that have a clear and measurable impact on the business. You will be responsible for the entire product lifecycle — from early ideation and prototyping to deployment, scaling, and optimization.

This highly hands-on position is ideal for someone comfortable with ambiguity and who enjoys transforming concepts into market-ready tools.

If you enjoy building AI systems, delivering features, experimenting, and turning vague ideas into concrete products, this role is for you.
