Job summary

We are building the trust layer for the agentic future. As AI agents move from simple chatbots to autonomous workloads with access to sensitive enterprise data the industry lacks a standard for Identity Authentication and Governance. This role focuses on the runtime software that protects and governs how AI-agent systems communicate in production. You will work close to application traffic secure service communication policy enforcement and runtime integrations across cloud-native and external environments. The work sits at the intersection of networking security and distributed systems. It is a strong fit for someone with deep Go and networking experience who wants to build the software that makes AI-agent execution safer more controllable and more production-ready.

What you will do

• Build runtime software that handles secure communication traffic control policy enforcement and service protection for AI-agent systems.
• Work on network-facing components such as application proxies traffic inspection layers secure communication libraries and runtime security services.
• Implement and improve HTTP TLS certificate handling request inspection authorization integration and performance-sensitive runtime logic.
• Partner with identity and platform engineers to connect runtime systems with authentication authorization audit and cloud deployment workflows.
• Improve runtime reliability observability performance and operability in production environments.
• Help define how secure runtime controls should work for modern AI-agent systems across internal and external execution environments.
• Support production incidents and continuously improve the safety and supportability of runtime systems.

What you will have

• 8 years of software engineering experience.
• Strong hands-on experience in Go. Additional fluency in Python Rust or C/C for systems-level work is a plus.
• Strong understanding of networking fundamentals: HTTP/1.1 and HTTP/2 TLS certificates proxies load balancing DNS and service-to-service communication.
• Experience building network-facing or security-sensitive systems such as gateways proxies service mesh data planes traffic filters SDKs or runtime security agents.
• Experience with Linux systems containers Kubernetes networking (CNI iptables eBPF) and cloud-native production environments.
• Good understanding of observability (metrics tracing structured logging) debugging performance tuning and production support.
• Experience with cloud security API gateways service mesh (Envoy stio Linkerd) or policy engines (OPA Cedar) is a strong advantage.

Nice to have

• Experience with SPIFFE/SPIRE Workload API transparent proxy patterns (iptables eBPF) async networking frameworks (aiohttp asyncio tokio) Envoy filter development WebAssembly plugins or protocol-level inspection (gRPC WebSocket MCP).

Benefits

• Generous time-off policies
• Top shelf benefits
• Education wellness and lifestyle benefits
