Senior Ground Systems Operations Engineer

About the company

SWISSto12 is one of the world’s fastest-growing aerospace companies, evolving from its pioneering use of 3D printing technologies for high-performance Radio Frequency (RF) products and applications to the manufacture of entire geostationary telecom satellites, called HummingSat. HummingSat is the world’s first commercial telecom GEO SmallSat developed in collaboration with the European Space Agency (ESA). Its compact size combined with highly capable telecom payloads allows telecommunications operators to deploy cost-efficient, agile assets without sacrificing performance or security. HummingSat has been selected by Intelsat, Inmarsat, and Astrum Mobile for multiple satellite builds. SWISSto12 is also a leading provider of RF products and sub-systems for satellite communication and remote sensing applications, leveraging patented 3D printing technologies to deliver lightweight, high-performance RF products.

Responsibilities

• Contribute to the configuration, operation, and evolution of mission control systems (e.g., Terma CCS), including databases, command and telemetry definitions, limits, displays, and operational configurations.
• Support setup, validation, and troubleshooting of ground systems environments used for simulations, testing, rehearsals, and live operations.
• Contribute to consistent configuration practices across missions while balancing mission-specific needs and operational constraints.
• Ensure ground system configurations are documented, supportable, and aligned with operational workflows.
• Participate in system-level troubleshooting spanning command & control software, flight dynamics software, and ground equipment.
• Contribute to the development, testing, and maintenance of operational procedures, including procedural scripting (e.g., Tcl).
• Support procedure validation activities such as dry runs, simulations, launch rehearsals, mission rehearsals, and mission readiness reviews.
• Assist in translating operational concepts into executable and repeatable procedures.
• Maintain procedure-related documentation to ensure clarity, traceability, and operational confidence.
• Support integration and operational use of ground equipment, including modems, baseband systems, antennas, and associated interfaces.
• Assist with configuration and troubleshooting of end-to-end command and telemetry paths.
• Work with Ground Systems, IT, and external partners to resolve operational issues involving hardware–software interaction.
• Collaborate closely with Flight Dynamics, Mission Operations, and Ground Systems Engineering teams to support mission execution.
• Contribute to operational rehearsals and early mission phases (e.g., LEOP/IOT), as required.
• Communicate clearly and calmly during operational activities and time-critical troubleshooting.
• Contribute to continuous improvement of operational practices, tools, and documentation.

Requirements

• Bachelor’s degree in Aerospace Engineering, Computer Science, Telecommunications, or a related field (or equivalent experience).
• Experience working in satellite ground segment or mission operations environments.
• Hands-on experience with command and control software (Terma CCS or equivalent).
• Experience developing or maintaining operational procedures, including scripting (Tcl, Python, or similar).
• Practical understanding of ground equipment interfaces, especially modem and baseband systems.
• Demonstrated ability to troubleshoot issues across software, configuration, and hardware boundaries.
• Ability to write clear, high-quality technical and operational documentation.
• Strong operational mindset with attention to detail and execution discipline.
• Excellent communication skills and comfort working across disciplines and cultures.

Fluent English required; French is a plus. Willingness to travel as needed for project requirements.

Pluses: Experience supporting multi-mission or shared ground infrastructures, exposure to flight dynamics tools or operational data flows, experience supporting simulations, rehearsals, or early mission operations.
