Jacob made an "accidental cameo" in Bread's Crumbs 2: Electric Boogaloo. While Scott filmed a scene in their high school engineering room, Jacob was seen sitting with Ryan Grier (who also made an "accidental cameo"). The reason this was an "accidental cameo" is because Jacob would go on to play Axel Gunner later in the series, which wasn't planned at the time of the second film's production. In 2017, Jacob was confirmed to have played Axel Gunner during his cameo.
In December 2016, Scott invited Jacob to join the cast of The Legend of the Creepy Guy in the Woods, in which he plays a minor character credited as Lutz. The film marked Jacob's first collaboration with Scott. The project was released several months later in March.
In April 2017, Jacob was cast as the main villain of The Two Man Trio, the last Bread's Crumbs interquel. He shot his scenes that month, with the film being released in May. The Two Man Trio served as his first major film role.
Also in April, Scott approached Jacob about building a helmet for a new, main antagonist in Bread's Crumbs 4: Mass Consumption called The Creator. Jacob began constructing the helmet that month, loosely basing it off of Scott's original designs for it.
On May 8, Jacob was confirmed to return as Gunner in Bread's Crumbs 4: Mass Consumption. He was set to participate in the production in either May or June, but due to scheduling conflicts was unable to participate in filming. Jacob and Eric Gorbaty were dropped from the cast on July 20, but Jacob was ultimately able to film his scenes the next day. Bread's Crumbs 4 was subsequently released in August.
