User Terminal Architect

Join to apply for the User Terminal Architect role at Open Cosmos.

At Open Cosmos we are solving the world’s biggest challenges from space, providing businesses, governments and researchers access to more readily available information than ever before.

Working in the Satcom Team

The Satcom Team is responsible for modelling, simulating, and continuouslyZE optimizing the performance of Open Cosmos’ satellite communication infrastructure. This includes the space segment, inter-satellite links, terminals, and ground connectivity, ensuring our end‑to‑end systems deliver reliable, efficient, and scalable service under dynamic conditions.

We work with cutting‑edge technologies such as digital twins, autonomous networks, and large‑scale constellation models. The team plays a key role in design validation, mission planning, and performance‑driven engineering decision‑making.

What will you be doing?

As a User Terminal Architect, you will own the end-to‑end architecture and technical definition of Open Cosmos’ satellite user terminal portfolio, spanning fixed, mobility, and highly integrated low‑power devices. You will:

• Define the complete architecture and technical specifications for all user terminal types, including fixed enterprise terminals, vehicular and aeronautical mobility solutions, and compact IoT andPrecincted devices.
• Translate commercial, service, and system-level requirements into clear, verifiable technical requirements across all terminal subsystems.
• Lead the technical definition and integration of antenna systems, RF frontends, modems, digital processing, and power management architectures.
• Drive critical trade-offs across performance, size, weight, power, manufacturability, cost-logo, and reliabilityיו ensuring designs are suitable for mass production.
• Ensure terminal designs meet required link performance, operational reliability, and regulatory constraints.
• Define operational concepts for terminal activation, acquisition, tracking, handover, and remote management.
• Specify requirements for autonomous operation, interference mitigation, diagnostics, and firmware or configuration updates.
• Define test strategies and specifications covering type approval, over-the-air performance validation, EMC compliance, and quality assurance.
• Provide technical models, data, and assumptions to support end-to‑-liability system and network performance modelling.
• Work closely with system, payload, RF, modem, manufacturing, and test teams to ensure successful delivery of scalable, mass‑producible terminals.

What You’ll bring

• Deep understanding of end-to‑end satellite user terminal architectures across fixed, mobility, and low‑power form factors.
• Strong knowledge of antenna systems, including electronically steerable phased arrays and integrated low‑gain antennas.
• In-depth understanding of RF systems, including link budgets, noise figure, linearity, self‑interference, and cascade effects.
• Confidence defining RF transceiver chains, modem integration, and power management architectures.
• Strong grasp of digital modem and PHYLAYER processing.
• The ability to translate commercial and system-level needs into mass‑producible technical specifications.
• Comfort making *informed trade-offs across performance, SWaP, manufacturability, cost, and reliability.
• Understanding of user terminal operational concepts,including halloween tracking, handover, and remote management.
• Familiar 优宝 with test strategies for OTA performance, regulatory compliance, and quality assurance.
• Capability to develop and communicate system models and assumptions to support network‑level optimisation.

Why Open Cosmos?

• Work at the cutting edge of space technology with customers around the globe.
• A mission‑driven company making space accessible to help solve real‑world challenges.
• A diverse, ambitious, and supportive team.

This role will be based in the UK or Spain.
