Senior RF Systems Engineer: Cloud-Driven Ground Stations

Viasat; Batam; On-site; IDR 2,129,673,000 - 3,076,195,000; Full time

Job summary

Viasat seeks a Senior RF Systems Engineer to design, integrate and test ground station RF systems across multiple bands with autonomy. This role is powered by cloud-based signal processing and modern DevOps practices and requires willingness to travel for site work.

Based in London, you will contribute to DiFi/VITA 49, RFoIP, and AI‑assisted workflows, while maintaining CI/CD pipelines and on‑call duties for Operations and NOC.

Qualifications

• 8–12 years ground station system design and test experience.
• Degree in Electrical/Electronic Engineering or Telecommunications.
• Proven RF expertise across multiple frequency bands with strong link budget and test skills.
• Working knowledge of DiFi/VITA 49, RFoIP, DevOps CI/CD, AWS/GCP, and AI engineering tools.

Responsibilities

• Perform detailed RF system design and analysis: link budgets, G/T, EIRP, linearity, antenna system characterisation across L/S/C/Ku/Ka/Q/V bands.
• Plan, execute, and document FAT, SAT, and IOT test campaigns for new and upgraded earth station RF systems.
• Contribute to DiFi (VITA 49) digitiser chain design, validation, and interoperability testing.
• Contribute to RFoIP encapsulation, QoS, PTP synchronisation, and SDR modem integration activities.
• Develop and maintain CI/CD pipeline stages, IaC modules (Ansible/Terraform), and automated RF test scripts.
• Deploy and support containerised RF signal processing workloads on AWS EKS or GCP GKE.
• Contribute to cloud RF data pipelines using AWS Kinesis / GCP Pub/Sub and post-pass analysis via Athena / BigQuery.
• Apply AI/ML tools to engineering workflows: LLMs for documentation, anomaly detection on RF telemetry, AI-assisted simulation.
• Provide third-line RF support to Operations and NOC, including on‑call rota participation.
• Produce and maintain engineering documentation (ICDs, test plans, acceptance reports) to P&CSE quality standards.
• Travel to earth station sites and supplier facilities as required by programme activities.
