Signadot is building the validation layer for agentic coding. As AI agents generate more code, verifying that it works against real systems becomes the bottleneck. This is a senior backend IC role building the Go control plane and APIs behind that validation layer, along with the enterprise features that let large organizations roll it out to thousands of developers.
What you'll do
Build and own core backend services in Go: the control plane, public APIs, and request routing
Design and maintain HTTP and gRPC APIs, and the SDKs generated from them
Build enterprise features such as RBAC, SSO, audit logging, and multi-tenancy
Work with Kubernetes, including controllers and operators
Own features from design through production, including testing and rollout
Keep the systems you own reliable and observable
What we're looking for
4 to 6 years building backend systems in production
Strong Go, or strong experience in another systems language and willing to work primarily in Go
Solid distributed systems fundamentals: you can reason about a multi-service system and where it fails
Experience designing APIs that other teams build on
Working knowledge of Kubernetes
Interested in both hard distributed systems problems and the enterprise features (RBAC, multi-tenancy, SSO) that make the product usable at scale
Clear written communication. The team works asynchronously and relies on written design docs
Nice to have
SRE or DevOps experience (a strong plus): production Kubernetes (EKS), CI/CD, IaC, observability
Experience working on validation/testing oriented products and/or agentic validation
Building or operating Kubernetes controllers or operators (controller-runtime, client-go)
gRPC, protobufs, or OpenAPI-driven SDK generation
Multi-tenancy, request routing, or service mesh internals (Istio, Linkerd)
Database design and operations, especially MySQL at scale
Contributing to or operating CNCF projects
