Oximy
The system of record for enterprise AI usage.
Founding Full Stack Engineer
About the role
Oximy is building the control layer that makes AI safe and manageable for the world’s most critical workloads. We are a small, fast team working at the intersection of security, network infrastructure, operating systems, and modern AI systems.
AI adoption inside enterprises is already widespread. Visibility is not. Tools span browsers, native desktop apps, agents, and personal accounts. Most organizations are flying blind.
We build the layer that shows what is actually happening.
The role
This is a founding engineering role with real ownership. You will build core product surfaces and also work closely to the system boundary (network, user kernels etc).
You’ll ship user-facing features, backend services, and native components across macOS and Windows. You’ll work on performance, data correctness, and the pipelines that turn raw signals into something enterprises can rely on. You’ll help shape the architecture that governs how AI usage is observed, interpreted, and acted on at scale.
This role cuts across product, infra, and systems. There is no strict line between “frontend” and “backend” here.
What you’ll work on
- Core product surfaces across Pulse, Spend, and Oversight
- High-signal UIs that explain AI usage to security, IT, finance, and AI teams
- Backend services and APIs that ingest and query large volumes of usage data
- Native macOS and Windows applications that operate close to the OS (Understanding the network is a huge plus!)
- Performance, reliability, and correctness across the stack
- Early customer deployments and feedback loops with real enterprises
- Internal tooling and pipelines that support measurement, analysis, and iteration
What we’re looking for
- Strong full-stack experience. You’re comfortable moving across frontend, backend, and systems code.
- Experience shipping production software used in real environments.
- Comfort working close to the OS (or curiosity to learn quickly).
- Good judgment around tradeoffs. You know when to go deep and when to keep it simple.
- Clear communication. You can explain what you’re building and why.
- Bias toward ownership. You don’t wait for permission to fix things.
Bonus experience
- Native desktop development (macOS or Windows)
- Systems programming or performance-sensitive code
- Security, observability, or enterprise infrastructure
- Data-heavy products or analytics platforms
- Model evaluation, fine-tuning, or GPU-backed systems (nice to have, not required)
What this role offers
This role is for someone who wants extreme ownership, fast iteration, and the chance to build foundational infrastructure early. You’ll be making decisions that matter, working with people who have built and scaled serious systems before.
Location
San Francisco preferred. Open to strong US-based candidates.
Compensation
Competitive salary. Meaningful equity. Early-stage ownership.
About Oximy
Oximy is building the infrastructure layer that makes AI safe for the world’s most critical workloads. AI systems hallucinate, leak data, and take unpredictable actions, and until they are secure, they cannot scale inside enterprises. We create the airlock between AI models and the real world so companies can deploy AI with confidence.
We are assembling a world-class team of founders, security engineers, and builders who have operated in high-stakes environments. We believe security should accelerate adoption, not slow it down. If you want to define how intelligent systems are secured at scale, you will do meaningful work here.
