Slater Certified® is an AI-powered workforce development platform for the water and wastewater sector. It delivers self-paced training that prepares professionals for licensure and continuing education, built around G.A.I.L. (Generative Artificial Intelligence Learning) - an interactive tutor that gives real-time feedback, personalized explanations and adaptive support, so someone studying on demand still gets guidance. The flagship course is a 40-hour Wastewater Class 3 Operator Training recognized by the Georgia Secretary of State, alongside a 24-hour continuing education course and an industrial wastewater program.

Organizations can run a customized version, Powered by Slater Certified®, against their own workforce.

Slater Certified, LLC is the workforce development arm of Slater Infrastructure Group, LLC - an Alpharetta, Georgia infrastructure services firm founded in 1997, working across operations and maintenance, construction engineering and inspection, and environmental services for public and private clients. Slater Certified launched in July 2025 and is licensed in Alabama, California, Florida, Georgia and Mississippi.

The team is small and moves fast. Technology choices are modern and made by the people who have to live with them, so the distance between an idea and a decision is short, and the distance between a decision and shipping it is shorter. Work is remote and the schedule is flexible. Ownership sits with the person doing the work, and there is real room to shape how things get built rather than inheriting someone else's process.

Slater Certified® runs a React front end and an Express back end on Vercel, with Firestore behind it and G.A.I.L., our generative AI tutor, at the center of the learning experience. The platform is live, it carries real learners against state-approved curricula, and it is about to be asked to do considerably more than it was originally built for.

This is a 100% hands‑on coding position. The person in this seat writes production code every day and builds the hardest parts of the platform personally. Architectural direction is set by the Chief Technology & Business Officer; you are the senior engineering voice feeding into those decisions and the person who turns them into working software.

It is a small team, so what you build reaches learners quickly and there is nowhere to hide.

Is shipping production code across the front end, API and data layer inside the first month, and keeps doing it for the life of the role.

Is the CTBO's working partner on architecture - bringing options, trade-offs and a recommendation rather than waiting to be told.

Sets the engineering standards that stick: testing, code review, what “done” means, and the release path from TEST to production.

Removes the top three scaling or reliability risks in the platform - identified inside the first 60 days, closed by month twelve.

Raises the technical level of the team around them, measurably, in code review and in what others are able to ship unaided.

Is the person the CTBO can hand a hard technical problem to and not follow up on.
