Job description
UNIVITY is looking for a Data Handling System (DHS) Engineer to join the team in Toulouse office. You will be reporting to the Satellite System Engineer.
As Data Handling System (DHS) Engineer, you will be involved in the avionics design, with a focus on the DHS architecture definition for the uniSky constellation.
Your key responsibilities and tasks:
(i) Design and technical definition
- Analyze mission needs and translate them into DHS technical requirements, according to the global avionics architecture
- Contribute to the definition of the architecture, including the onboard computer, GNSS, memory units, interface equipment and communication buses.
- Specify functions for telecommand handling, telemetry collection, time synchronization and data storage.
- Contribute to the definition of operating modes and Failure Detection, Isolation and Recovery (FDIR) mechanisms.
- Assess the optimized trade-off between cost, reliability and operability of the architecture, in the frame of a massive constellation.
(ii) Development and interface management
- Prepare and maintain technical specifications and Interface Control Documents (ICDs).
- Work with embedded software, and all other sub-systems involved in the platform and payload teams to ensure interface consistency.
- Participate in supplier’s product analyses, evaluation & selection according to mission need and industrial and production constraints.
- Follow-up suppliers’ technical activities (product development, evolutions, testing & delivery).
- Prepare technical inputs for design and participate in the qualification reviews.
- Assess change requests and non-conformances, and propose appropriate solutions.
(iii) Integration, verification and validation
- Provide inputs for the definition of the validation philosophy in the frame of massive constellation.
- Participate in the flatsat design for the DHS subsystem.
- Define tests, write procedures, execute them and analyze results.
- Participate in the satellite-level integration and testing campaigns alongside Assembly, Integration and Test (AIT) teams.
- Investigate anomalies, identify root causes and contribute to corrective actions.
- Maintain traceability between requirements, tests and verification results.
Key deliverables:
- Technical specifications and interface documentation.
- Sizing analyses and performance budgets.
- Contributions to the DHS architecture documentation.
- Test procedures and reports.
- Verification matrices and anomaly analyses.
- Technical inputs for development reviews.
Profile required
Skills and experience:
- Minimum master’s degree level qualification in electronics, embedded systems, computer engineering or space engineering, and have 3–5 years of experience in embedded systems development or validation, preferably in the space industry.
- You have contributed to a project involving an embedded computer, communication networks or data handling functions. You can independently manage a defined technical scope while seeking approval from the Systems or Avionics Lead for major design decisions.
- Practical experience in requirements management, specification writing and functional verification.
- Experience of embedded computer architectures, memory systems, real-time systems, communication buses or protocols, such as SpaceWire, CAN, Ethernet or serial interfaces.
- Experience applying standards like ECSS, or CCSDS is an asset.
- Proficiency in Python, C,/C++, Matlab or similar languages.
- Professional proficiency in written and spoken English.
People come in different shapes and sizes and it is difficult to write a job description for someone we have not yet met. Therefore if you are not sure that you meet all the criteria, or if you think that you may have something different to offer, we still want to hear from you.
