We don't just sell AI agents.
We run our company with them.
TierZero isn't a traditional software company that bolted AI onto an existing product. We're AI-native: we use AI agents to build, ship, and operate our own infrastructure.
That's not just our story. It's proof the product works. We operate at a scale that would normally require a much larger team — because we actually believe agents can replace headcount, and we built ours to prove it.
When we tell you “you don't need to scale your team proportionally,” we're speaking from experience.
Meet the team
A team of staff software engineers and ML practitioners from the early days of Facebook, Databricks, Brex, Nextdoor, and LangChain. We know what excellence looks like.
Our values

Give Trust, and Opinions
We trust each other to execute independently and speak up with ideas or concerns. Challenge openly, assume positive intent, and move fast without politics.

Be the Customer
Everyone talks to customers directly. We build with empathy, deliver more value than we charge for, and make customers wish we were on their team.

Love the Journey
Startups are hard. We're here because we enjoy building something meaningful together. Celebrate small wins, sustain the pace, and don't let the lows drag you down.

Build Intentionally
Move quickly, but with focus. We don't chase every shiny object. Think through decisions, debate the approach, then execute sharply. Less hype, more substance.

Everything is Figureoutable
Default to optimism and creative problem-solving. The answers aren't always obvious, and that's okay. With enough creativity and persistence, we'll find a way.
Our values shape everything: from how we treat each other, to what we ship
Let the Builders Build
Engineers are spending way too much of their time maintaining their systems, firefighting, and answering support tickets. By letting AI agents handle these tasks, we can free up engineers to focus on building. At TierZero, we believe engineers should spend 100% of their time dreaming and building the future.
We operate at the frontier of AI, systems, and observability, combining applied research with hardcore engineering. We're looking for exceptional technical people that want to work collaboratively in-person in our San Francisco office.
