Full Time Round Rock, TX, US

Job Purpose/Summary

The Senior Infrastructure Engineer will lead the design, automation, security, and lifecycle management of the environments used to build, integrate, validate, release, and demonstrate our next-generation space and critical infrastructure defense platform. The role will own internal development, quality-assurance (QA)/release-candidate (RC), and demonstration infrastructure, including repeatable environments that may support future business-development demonstrations.

Working closely with Product, platform/backend engineers, frontend engineers, machine learning engineers, security stakeholders, and Business Development, the engineer will translate platform, release, and demonstration requirements into infrastructure design, implementation-ready technical specifications, infrastructure as code, controlled release promotion workflows, observability, runbooks, and durable engineering decision records. They will ensure that data-intensive platform capabilities can be provisioned consistently, tested safely, and demonstrated reliably.

This is a senior, hands-on individual-contributor role with no direct reports. Under the current platform-as-a-product model, customers are intended to deploy and operate production infrastructure through their own Dev Ops teams. This role will provide reference architectures, deployment artifacts, hardening guidance, documentation, and technical handoff, but is not responsible for routine customer production deployment or ongoing production operations. Production or hosted SaaS operational ownership would be added only if the company establishes a separately scoped service with defined service-level obligations.

Success in year one includes standardizing internal environments, improving release repeatability and security, accelerating developer feedback, and enabling dependable demonstrations without creating non-scoped production-support obligations.

Duties and Responsibilities

• Development infrastructure:
  Provide dependable, developer-friendly environments and shared services that support local and remote development, integration testing, observability, and rapid feedback.
• QA and release-candidate infrastructure:
  Build and maintain isolated, reproducible QA and RC environments that support regression testing, upgrade validation, release acceptance, rollback rehearsal, and performance characterization before a release is approved.
• Demonstration and business-development environments:
  Create secure, and repeatable demonstration environments that can be provisioned for internal reviews and customer or partner demonstrations, including controlled access, representative data, and readiness checks.
• Infrastructure as code:
  Design, implement, review, test, and maintain multi-platform and platform specific reusable infrastructure-as-code and configuration-management modules, environment definitions, state-management practices, and automated provisioning and teardown workflows.
• Container and orchestration platforms:
  Establish and evolve the workload orchestration, networking, storage, identity, and policy patterns required to run the platform consistently across internal environments.
• CI/CD and Git Ops:
  Design and maintain secure delivery workflows for infrastructure, services, configuration, and data migrations, including automated validation, environment promotion, approvals, deployment status, rollback, and traceability.
• Artifact and release promotion:
  Define controlled promotion of container images, deployment packages, configuration, and other release artifacts across development, QA, RC, and demo environments, with versioning, compatibility checks, provenance, and retention.
• Dev Sec Ops  and software supply chain:
  Integrate vulnerability scanning, dependency and container assessment, software bills of materials, artifact signing, provenance, policy gates, patch tracking, and remediation workflows into the engineering and release lifecycle.
• Identity, secrets, and infrastructure security:
  Implement least-privilege access, workload and user identity, secrets and certificate management, network segmentation, secure administrative access, auditability, and environment-specific security controls.
• Observability and reliability:
  Establish logs, metrics, traces, dashboards,…
