Telco SRE Engineer

AST SpaceMobile is building the first and only global cellular broadband network in space to operate directly with standard, unmodified mobile devices based on our extensive IP and patent portfolio and designed for both commercial and government applications. Our engineers and space scientists are on a mission to eliminate the connectivity gaps faced by today’s five billion mobile subscribers and finally bring broadband to the billions who remain unconnected. Position Overview We are looking for SRE/DevOps to join our AST’s Telco Software Development team to design and develop innovative telco software solutions and components. This is a hands-on engineering role for engineers who are motivated by building genuinely novel software in a fast-moving, greenfield environment. You will be embedded in a small, high-ownership team where your code ships into real network infrastructure, and where the technical decisions you contribute to will directly shape AST’s long-term differentiation. Candidates may come from a software engineering background (strong systems and backend, ideally with telecom exposure) or from other related engineering domains with solid software development skills. Key Responsibilities: Design and implement GitOps-driven infrastructure on Kubernetes using ArgoCD for continuous deployment and declarative infrastructure managementDevelop Infrastructure-as-Code (IaC) solutions for telco infrastructure using Terraform and CloudFormationBuild and optimize GitOps pipelines for automated, auditable infrastructure and application deploymentsManage containerized workloads on Kubernetes clusters supporting LTE/5G core and RAN servicesImplement and optimize monitoring, logging, and alerting systems using Prometheus, Grafana, ELK, and similar toolsTranslate architectural specifications, interface control documents (ICDs), and functional & non-functional requirements into clean, well-tested, production-ready codeAutomate operational tasks to reduce manual toil and improve system reliability through declarative configuration managementDocument infrastructure architecture, runbooks, and standard operating proceduresCollaborate with network engineers and software teams to ensure seamless infrastructure integration Qualifications Education: Bachelor’s or Master’s degree in Computer Science, Telecommunications Engineering, or a related field — or equivalent professional experience. Experience: A minimum of 3+ years of DevOps/SRE production experience – exposure to telecom or network related development projects is a plus. Strong proficiency with Kubernetes, GitOps (ArgoCD), and containerization on AWS, Azure, or GCPInfrastructure-as-Code (Terraform, CloudFormation) and declarative CI pipelines (Azure pipelines, GitLab CI, or similar)Networking fundamentalsScripting/automation (Python, Bash, Go) and operations: monitoring (Prometheus, Grafana, ELK), security, complianceDemonstrated problem-solving ability and ownership mindsetEnglish proficiency at B2 level or above; able to collaborate effectively with peers and architects in a globally distributed team Preferred Qualifications: Advanced GitOps patterns: multi-tenancy, multi-cluster, progressive delivery (Argo Rollouts); familiarity with Flux or alternative frameworksService mesh expertise (Istio, Linkerd) in containerized environmentsDeep telco domain knowledge: RAN (gNodeB, CU/DU), 5G Core (5GC, network slicing), LTE Core (EPC, MME), BSS/OSS platforms5G SA/NSA architectures, NFV, and network function testingSDN, OpenFlow, and edge computing (MEC) fundamentalsPrevious experience at telecommunications carrier or major telco vendorRelevant certifications (Kubernetes, AWS, GCP, or telco-specific) Soft Skills: Strong analytical and problem-solving skills - able to break down complex, under-defined problems and deliver working software iterativelyHigh ownership mentality - take personal responsibility for the quality and correctness of your own work, not just task completionCollaborative and communicative - actively participates in design discussions, code reviews, and cross-functional conversationsCurious and self-directed - proactively learns domain context (telecom protocols, network architecture) beyond what is immediately required for the next ticketComfortable with ambiguity and greenfield work - able to operate effectively when specifications are evolving and there is no legacy codebase to referenceAttention to detail in code quality, test coverage, and documentation Technology Stack: Deployment & Container Orchestration: Kubernetes (EKS, on-premises) Helm, Kustomize (package management and templating) ArgoCD, Flux (GitOps continuous deployment) Infrastructure & IaC: Terraform, CloudFormation (infrastructure-as-code) AWS: EC2, ECS, EKS, VPC, networking Linux CI/CD & Version Control: Azure pipelines, GitLab CI (declarative pipelines) Git (version control, branching strategies) Observability & Monitoring: Prometheus, Grafana (metrics collection and visualization) ELK Stack (Elasticsearch, Logstash, Kibana) for logging Datadog, New Relic (APM and distributed tracing) Telco Infrastructure: 3GPP standards and specifications RAN: gNodeB, eNodeB, CU/DU split architectures 5G Core: 5GC, network slicing, service-based architecture (SBA) LTE Core: EPC, MME, SGW, PGW OSS/BSS platforms and network management systems Programming & Scripting: Python, Bash, Go REST API design and integration Physical Requirements Ability to work in a standard office or remote home-office environment and use a computer for extended periodsAbility to participate in occasional after-hours incident response actions This job description may not be inclusive to the duties and responsibilities listed. Additional tasks may be assigned to the employee from time to time or the scope of the job may change as needed by business demands.
