Team Trailblazers at WirelessCar is building Drive, an Internal Developer Platform designed to make it easier for WirelessCar developers to build and run customer solutions. We're looking for a person who is willing to learn everything there is to know about messaging technologies like NATS. Both from an operational perspective but also from the perspective of how to use them for building the best possible solutions for the customers of WirelessCar.

About team Trailblazers

Trailblazers is a cross-functional platform engineering team shaping the future platform for hundreds of developers. As a part of this team you will influence architecture, innovate, and see your impact directly in production. The team thrives on collaboration and shared ownership.

What you'll work on

• Operate and scale NATS clusters: monitor, tune, and troubleshoot production NATS infrastructure; take part in incident response and capacity planning

• Improve observability and SRE practices: dashboards, alerts, and tracing that help teams debug their own messaging issues

• Create actionable documentation with real-world examples: clear examples, runnable code, troubleshooting guides

• Build developer tooling: create CLIs, APIs, or Kubernetes operators that let teams provision messaging resources on-demand through self-service tooling

• Continuous improvements: continuously work on designing, fine-tuning and ensuring the best possible clustering topology

• We pair and mob by default, expect collaborative coding sessions multiple times a week.

What we're looking for

• Experience working in production environments: monitoring, alerting, incident response, and post-mortems

• Ability to work in an ambiguous environments: it's part of your job to discover the options, document trade-offs in lightweight ADRs to drive a decision, then make sure the implementation reach production

• Willingness to go deep on NATS internals: clustering, JetStream, subject hierarchies, security models

• Solid understanding of distributed systems: you've debugged distributed systems in production and understand how to approach network partitions, performance degradation, and message processing bottlenecks

Nice to have

• Experience from operating systems running on Kubernetes

• Hands-on experience designing and operating messaging systems or other high-throughput distributed systems

• You've built or contributed to open source (we maintain NAuth, a Kubernetes Operator that enables GitOps of NATS AuthN/Z configuration)

• Experience of Helm charts and Kubernetes CRDs, we value experience in crafting users interfaces with those or similar technologies

• You write Go or want to learn how to write idiomatic Go of high quality

• Interested in or already using AI Agents for development

• You've worked with GitOps (ArgoCD, Flux, or Kargo) and understand how to work with declarative infrastructure definitions

If you want to write about your work or speak at conferences, we'll support you!
