Your people spend too much time moving information between systems.
Pick a real workflow, test where AI helps, and build around the parts that still need human judgment.
Product engineering
You know what needs to exist. Now it needs to get built.
Scope and build the software, integrations and internal tools your team needs to run the business.
Technical decisions.
Business context.
Fifth Nine is led by Matt Voska, a technology operator with 15+ years of experience in architecture, engineering and operations.
The work starts with how your company runs: where your team loses time, which systems they depend on, and what a useful result would look like. Scope and responsibilities are agreed before the build begins.
A good fit: you want senior direction and hands-on technical work, with your own team involved in the decisions.
