Join our mission to redefine satellite communications by delivering GEO capabilities in a smaller, faster, and more cost-effective package through the SiltaSat project.

As a Senior Payload Engineer, you’ll be at the heart of our Small Satcom evolution, working end-to-end—from design and development to AIT—alongside a team of experts. Your expertise in RF and optical engineering (with digital capabilities as a plus) at both board and system level will be critical to shaping the future of GEO communications payloads.

Responsibilities

• Being part of the technical lead team of telecom payloads for Small Satcom product.

• Architectural design of communication payloads including RF and Optical.

• Budgeting and maintaining the main parameters of each payload (Mass, consumption Dissipation and all relevant performance parameters).

• Manage and interface with the team members responsible for the other satellite subsystems.

• Define and analyse different components of the telecom payload, from passive units, RF active units to digital and optical components.

• Develop relationships with suppliers; to define the design and the manufacturing AIT required.

• Define and prepare SoWs and specifications, work with the program team to assure the implementation of the design through the planned activities.

• Solving problems along with the rest of the subsystems to assure an efficient implementation of the mission.

• Working jointly with the AIT team to design and implement all relevant activities for the payload atl all levels (subsystem and satellite level)

• Test Specification and Procedures development

• Subsystem documentation shall be performed based on the architecture, analysis and units

• Subsystem AIT (Activities of Integration & Test) based on the architecture shall be developed

Skills and Requirements

• Minimum 10 years of real-world experience with comms payload system architecture, requirements definition, flow down, tracking and performing system-level analyses.

• Strong experience with geostationairy satellites.

• Experience in design or implementation of RF equipment used for telecom satellites (SSPAs, TWTs, distributed amplifiers, phased arrays, passive units like filters, switches, etc.).

• Experience in design or implementation of digital processors (transparent or regenerative) for satellites.

• Ability to analyse data, derive conclusions, and manage design documentation as well as review and approve design changes

• Ability to trade-off and optimize performance, resolve complex technical problems, manage technical work with partners.

• Extensive experience with various relevant system modelling and analysis tools is a must (electromagnetic, antenna simulation, general purpose coding tools, etc).

• Autonomous and proactive working style and team work oriented.

• Fluent written and spoken skills in English.

• Experience in ground segment is a plus.

What does ReOrbit do?

ReOrbit builds the foundation for the next generation of space applications by transforming satellites into truly intelligent, interconnected platforms, defined by software. Our satellite design philosophy revolves around the idea that satellites must network, communicate with each other and thus improve mission efficiency. How can this be achieved? Thanks to a flexible software-first architecture, where all these aspects are dealt with upfront in the mission concept, as integrated functionalities.

ReOrbit’s top-notch team of software engineers and system architects develop in-house software, procure hardware from the best-in-class suppliers, and seamlessly integrate the components to create flexible and secure satellites. Today, we are a rapidly growing company building a very strong multidisciplinary team to support our activities.
