Key Responsibilities
- Architect & Build: Design and maintain high-scale developer tooling and backend services that improve productivity and reliability across a distributed cloud environment. We operate in a 100% modern, cloud-native ecosystem, and you will work exclusively with epoxy?
- Infrastructure as Code (IaC): Treat infrastructure as a first-class citizen. You will define, deploy, and manage entire environments using declarative IaC (Terraform), ensuring our platform is reproducible and version-controlled.
- Drive Systemic Quality: Identify and eliminate systemic bottlenecks in the software development lifecycle (SDLC) through architectural changes or advanced tooling.
- Scale & Reliability: Ensure our infrastructure remains resilient under massive traffic loads while optimizing for performance, cost-efficiency, and near-real-time telemetry processing.
- Strategic Leadership & Mentorship: Define platform standards and reference architectures that span a 1–3 year horizon, balancing feature velocity with long-term technical debt. Act as the "glue" across teams, consulting on infrastructure best practices and up-leveling the organization through mentorship. Qualifications Required Qualifications
- 8+ years of relevant experience with the following:
- Foundational Technical Proficiency: Strong experience in at least one backend language (e.g., Go, Java, Python, or Rust). We value fluency and the ability to write modular, testable code over knowing a specific syntax.
- Strong proficiency in at least one backend language (e.g., Go, Java, Python, or Rust). We prioritize the ability to write modular, testable code over knowledge of a specific language syntax.
- Deep Systems Expertise: You go beyond "using" the cloud; you understand how it works. This includes:
- Cloud-Native: A solid understanding of cloud-native concepts and experience working with cloud providers like AWS or GCP. You should be comfortable navigating Kubernetes and container-level logic.
- Operating Systems & Compute: Deep knowledge of Linux internals, process management, and resource isolation.
- Networking & Security: Understanding of the OSI model, service meshes, load balancing, and "zero-trust" security architectures.
- Distributed Systems: Experience building and debugging systems that deal with CAP theorem trade-offs, eventual consistency, and distributed tracing.
- Reliable Execution: A track record of completing assigned tasks/tickets reliably and estimating work effectively within a
