Jobs at Sphinx Defense

Manage end-to-end infrastructure deployments: receive and validate enterprise hardware, commission bare-metal servers, configure virtualization (VMware ESXi/KVM), storage (SAN/NAS), and networking (VLANs), collaborate with vendors and engineering teams, perform hardware acceptance testing, document standards, and transition production-ready environments to DevOps while maintaining security and multi-site consistency.

Develop and lead full-stack engineering for secure mission-planning and command-and-control software supporting space communications programs. Responsibilities include building performant web applications, designing APIs, translating UI/UX designs into interfaces, improving backend services, conducting code reviews, mentoring junior engineers, and owning features end-to-end. The role requires work in secure or air-gapped government environments and eligibility for TS/SCI access.

Build, maintain, and operate AWS-based Kubernetes (EKS) infrastructure and CI/CD pipelines. Develop Terraform modules, Helm charts, and automation (Python/Go). Ensure platform reliability, security (IAM/cross-account), observability, and troubleshoot production issues while supporting cross-functional engineering teams and classified program requirements.

Design, build, and operate automated build and deployment infrastructure (GitLab CI/CD, Atlantis). Maintain multiple production Kubernetes clusters, package software as Helm charts, author Terraform cloud infrastructure, configure a federated message bus, maintain CI/CD pipelines, and mentor junior engineers. Support software teams and own technical problems end-to-end for space communications systems serving the U.S. government.

Design, build, secure, and maintain resilient enterprise and classified network infrastructure. Support routers, switches, firewalls, DNS/DHCP, perform packet analysis and monitoring, troubleshoot LAN/WAN issues, implement network security controls and segmentation, collaborate with cloud and cybersecurity teams, and produce operational documentation and reporting.

Support AWS-hosted and on-premises Kubernetes environments, maintain platform reliability and security, improve GitLab CI/CD pipelines, develop Terraform IaC, assist Helm deployments, troubleshoot infrastructure and application issues, and support deployments into classified environments.

Lead design and implementation of core backend platform services for a ground communications and data-transport system supporting US government satellites. Build multi-tenant cloud services, APIs, and automated, secure infrastructure; own technical problems end-to-end and mentor junior engineers while collaborating across the team.

Lead design and development of multi-tenant backend services and APIs on public cloud (AWS). Focus on automation, testing, security, scalability, and performance. Mentor junior engineers, interact with customers/partners for integrations, and solve space communications platform challenges.

Maintain and improve AWS-based Kubernetes infrastructure, GitLab CI/CD pipelines, Terraform modules, and Helm deployments for a satellite communications platform. The role focuses on cloud reliability, security, observability, IAM, troubleshooting, automation, and operational support across distributed engineering teams.

Company invites speculative applications for software roles solving national security space problems. Uses open-source technologies, values collaboration and transparency, encourages applicants even if they don't meet every requirement, and requires eligibility for U.S. security clearance and specific immigration statuses.
