Open positions
Senior Backend Engineer
Build APIs for policy enforcement, approval workflows, and audit logging. Python, FastAPI, PostgreSQL.
Full Stack Engineer (Frontend)
Design and build the UI for the Arx platform. React, TypeScript, Next.js. Work on approval queue, agent registry, audit trail.
Enterprise Sales Engineer
Partner with Fortune 500 security teams. Deep technical knowledge of the Arx platform required. Help enterprises understand governance.
Product Manager
Own the roadmap for approval workflows and compliance features. Work with customers, engineering, and the design team.
Engineering Internships
Arx is building the governance and control plane for security AI agents. Our engineering internship program is not a traditional learning role—you'll ship real code, work on production systems, and own components that enterprises depend on.
Program Structure
- Duration: 8–12 weeks (flexible)
- Time Commitment: ~15–30 hours per week
- Format: Remote-first with weekly engineering check-ins
- Collaboration: Async via GitHub, Slack, and internal tools
The Claude-First Approach
You'll develop using Claude Code as your primary development platform, paired with Claude models (Sonnet, Opus, Haiku) for building governance layers, policy enforcement, and observability systems. Claude Code is your primary tool, supported by traditional development practices (Git, CLI workflows, testing frameworks) to build production-grade systems.
This is hands-on experience with the full Claude ecosystem in a real enterprise security context.
Engineering Tracks
Choose one of five core engineering tracks. You'll own your assigned component end-to-end.
API & Integration Layer
Build and maintain connectors to security and infrastructure tools. Design governed operations (read/write actions). Handle authentication, rate limits, and failure modes. Pair Claude Code with Python/Node.js backends to ship secure integrations.
Agent Execution & Control Plane
Work on the intercept → evaluate → log pipeline for Claude agents. Implement policy enforcement logic and risk scoring. Make execution decisions (permit / escalate / deny). Ship a component that directly governs how Claude agents execute in production.
Observability & Logging
Build logging pipelines and tamper-evident audit trails for agent actions. Ensure traceability across systems. Integrate with SIEMs or logging backends. Own the observability layer that enterprises audit for compliance.
Reliability & Platform Stability
Improve error handling, retry logic, and failure recovery. Add monitoring, alerting, and health checks. Ensure system resilience under real-world conditions and high load. Build the reliability layer that makes production systems safe.
Developer Experience
Improve SDKs and internal tooling for building new integrations. Simplify onboarding for developers. Build test harnesses and validation workflows. Make it easier for teams to ship faster and safer.
What You'll Gain
- Real-world experience: Ship production code on day one. No side projects or training wheels.
- Claude expertise: Deep hands-on experience with Claude Code, Claude models, and governance patterns.
- Security & AI: Learn how enterprises deploy and control AI agents safely.
- Mentorship: Direct feedback from the founder on architecture and execution.
- Clear path forward: Top performers transition to Core Builder roles or full-time positions.
What We're Looking For
- Engineers who can build and ship, not just prototype
- Comfortable debugging real systems and APIs
- Understand backend systems, distributed workflows, or infrastructure
- Take ownership of problems end-to-end
- Bonus (not required): Experience with security tooling, AI systems, or observability
Tech Stack
- Development: Claude Code (primary) + Python / Node.js
- Frameworks: FastAPI, Django, Express, or Next.js (depending on track)
- Infrastructure: Cloud-hosted services, Docker, Kubernetes
- Data: PostgreSQL, event streams, logging pipelines
- Tools: GitHub, CLI workflows, Git, internal SDKs
Next Steps
If there's alignment, we'll:
- Define your engineering track
- Scope an initial project (2–4 weeks)
- Set clear deliverables and success criteria
- Ship code with feedback loops
Why Arx?
- Solve hard problems — AI security and compliance is new territory. Every solution you build helps enterprises understand and govern AI safely.
- Work with amazing customers — You'll partner with Fortune 500 CISOs, security engineers, and architects who are building the future of AI in enterprise.
- Great team — Security-first culture. People who care about shipping the right thing, not just shipping fast.
- Impact — Your code directly impacts how enterprises deploy AI. High stakes, high impact.
