Job description

Why SalesApe?

Join SalesApe, one of the fastest-growing AI companies, recognized as a leader in cutting-edge AI technology and backed by over $20 million from top VCs.

We’re at the dawn of a powerful evolution, set to transform society with our tech. Our mission? To tackle inequality by empowering a large market of non-tech SMBs—93% of all businesses, including construction, automotive, real estate, and more. While the tech industry has grown through computing power, these businesses have been technically starved.

With AI agents and our natural language interface technology, we’re unlocking significant productivity gains for our clients. It’s rewarding to see small businesses transform as they embrace their agent—not just as a tool, but as a trusted team member. The emotional bond our clients feel toward their agent is undeniable—they often say their ‘Ape’ has become part of the family. Our vision is to become the ‘brain’ of a business, spinning out agent workers, freeing up time, and simplifying operations to allow humans to focus more on real-life interactions.

Join Us for High-Energy, Impactful Work

Our Mission and Purpose:

As we built with large language models and AI-powered natural language interfaces, I had an aha moment. It became clear how significant this inflection point is: compute—the raw power of computers—is now accessible to people who don’t use computers.

Think of electricity’s arrival: it didn’t just light homes; it transformed industries, democratized wealth, and empowered everyone to grow and thrive. Today, AI offers a similar opportunity.

For two decades, the tech industry has had an advantage. Computers have been like co-pilots, quietly amplifying productivity and enabling rapid growth. But 95% of businesses—builders, plumbers, real estate agents—have been technically starved. These businesses account for 50% of GDP, five times larger than the entire tech industry, yet lack the tools to compete.

This is the inequality we aim to solve. APE AI is democratizing technology, bringing compute power to underserved businesses. We’re empowering real people—small business owners whose success impacts families, communities, and society. Seeing these businesses embrace their agent as a trusted team member is deeply rewarding.

For me, this mission is personal. I’ve built companies encouraging real-life connections, activity, and community engagement. This isn’t just about productivity; it’s about health, happiness, and thriving societies. Humans are wired for interaction, movement, and real-world engagement. Ape AI helps make this possible—empowering businesses that create real-world value to thrive alongside tech giants.

This isn’t just about technology. It’s about fairness—giving compute power to those who need it most so they can grow, thrive, and make a difference. That’s our mission, and it’s something we can all be proud of.

The Role:

We are recruiting an experienced Full Stack Developer to work on an exciting AI product. Reporting to the Head of Engineering, you’ll collaborate with a small, skilled team to deliver groundbreaking products. The work is challenging, varied, and rewarding. We seek someone eager to take on new challenges and collaborate effectively to solve complex problems.
