Full Stack Engineer
Strong engineer. AI-native builder.
We want a serious engineer first: someone who understands architecture, owns production systems, and knows how to build efficiently. You also work AI-native — prompting, steering models, shipping fast — but that is the accelerator, not a substitute for engineering judgment.

About Buzzed
Buzzed Technologies builds custom AI and software embedded in how companies actually operate. We automate intake, internal workflows, LLM pipelines, and production systems for businesses that want infrastructure they own, not another subscription.
How we deliver is simple. A Hunter taps their network and puts the right company in front of us. A Sponge absorbs that business until they know it cold and becomes the single context source for the build. A Full Stack Engineer ships the product using AI-native workflows, working from the Sponge's specs instead of going back to the client.
The problems are high-stakes, data-dense, and unforgiving. Clients depend on what we ship. When something breaks, it breaks in production, not in a slide deck.
We hire people with high agency and high urgency. We look for slope over intercept. We care less about where you trained and more about what you have built. At Buzzed, everyone owns a distinct part of the loop and makes consequential decisions that shape the outcome.
If you want to build systems that directly shape how companies run, Buzzed is the place to do it.
About the role
Buzzed is looking for a Full Stack Engineer with a strong traditional engineering background: real experience with architecture, data models, APIs, frontends, infrastructure, and production systems you have owned end to end. That foundation is non-negotiable.
You also build AI-native. You use AI to write the code you ship, you are fluent in prompting and prompt engineering, and you have been doing it long enough to know the difference between moving fast and creating a mess. We are not looking for a vibe coder. We are looking for someone who can hold the architecture in their head while using AI to execute at a pace manual coding cannot match.
You work from a Sponge's specs and context, not from direct client access. When something about the business is unclear, you ask the Sponge. That is the loop: Hunter opens the door, Sponge absorbs the business, you build the product.
This is a company-wide role. You sit on everything Buzzed runs: internal ops tooling, shared auth and data layers, deployment pipelines, reusable components, and the core systems every client engagement plugs into. We work in-person in NYC because this role is about judgment, speed, and ownership. Backgrounds that tend to be a strong fit: senior full-stack or platform engineers with production ownership, technical leads who set architecture while still shipping, or builders who combine deep systems thinking with a disciplined AI-native workflow.
What you'll do
- Own Buzzed's core stack end to end: architecture, data models, APIs, frontends, infrastructure, and deployment.
- Design shared systems and patterns the team reuses instead of reinventing on every engagement.
- Ship production software using AI-native workflows — prompting, steering, reviewing, and refining until the output is maintainable.
- Build from Sponge specs and context. You do not go back to clients for answers.
- Integrate LLMs at the platform level: evals, observability, fallbacks, and reusable workflow patterns.
- Keep production reliable across every surface Buzzed operates on and make the technical calls that keep the stack coherent.
What you'll need
- Strong engineering fundamentals. You understand architecture, can reason about tradeoffs, and have owned production systems — not just shipped features inside someone else's design.
- Deep TypeScript and modern web stack experience (React, Next.js, Node). Python is a plus.
- AI-native workflow. You use AI to write most of the code you ship and you have enough experience to steer it toward correct, efficient, maintainable output.
- Prompting and prompt engineering fluency. You know how to get good results from models because you understand both the tools and the underlying systems.
- Ability to work from written specs and a single context source without needing direct client access.
- Strong judgment. You know when AI output is good enough, when it needs rework, and when the architecture itself is wrong.
Nice to haves
- Track record building shared internal platforms, infra, or developer tooling other teams depended on.
- Experience with AI workflow infrastructure: eval pipelines, observability, fallbacks, or production LLM integrations.
- Early-team experience at a high-growth startup where you set technical direction while still writing code.
- Comfort jumping from a client build to an internal dashboard to a shared library refactor in the same week.
Compensation
$300K–$800K / year.
Full-time, in-person NYC compensation for a senior engineer with company-wide ownership of how Buzzed builds and runs software. The range reflects scope, seniority, and how much of the stack you can own independently.
- Full-time, in-person role in New York City
- Senior engineering ownership across Buzzed's full stack
- AI-native workflow expected; strong architecture and production judgment required
- Build from Sponge context; no direct client interface required
Apply to own the stack.
Show us your engineering background and your AI-native workflow: what you have owned in production, how you use AI to build, and why you can hold architecture while shipping fast.
