Satellite Reliability & Space Safety Engineer (all genders)

You will support mission-lifetime assessments and lead technical analyses required to demonstrate compliance with ESA and DLR debris-mitigation and end-of-life requirements. Over time, you will help establish reusable methods, tools and reliability evidence across Reflex missions and internally developed spacecraft products.

Reliability, Lifetime & Space Safety

• Perform debris-mitigation, disposal and end-of-life analyses against ESA, DLR and other applicable requirements.
• Develop and document compliance justifications, including disposal reliability, passivation, accidental break-up risk, orbital lifetime and re-entry assessments where applicable.
• Develop reusable analysis methods and workflows using Python, DRAMA, SARA and similar engineering tools.
• Develop quantitative spacecraft reliability and mission-lifetime assessments to support customer and mission commitments.
• Assess the reliability of mission-critical and end-of-life functions using supplier data, qualification evidence, degradation analyses, redundancy concepts and flight heritage.
• Define pragmatic compliance and assurance approaches suitable for NewSpace development, including justified assumptions, tailoring and alternative evidence where appropriate.
• Define and review reliability, qualification and heritage evidence required from suppliers and internally developed Reflex products.
• Build reusable models, datasets and methods that can be applied across Reflex missions and products.

Systems Engineering

• Work closely with Mission Systems Engineers and subsystem teams to integrate reliability, lifetime and space-safety considerations into system design.
• Use outputs from FMEA/FMECA, FTA, FDIR and subsystem analyses as inputs to mission-level reliability and compliance assessments.
• Support technical trades, verification planning and qualification activities where reliability, lifetime or regulatory compliance are significant drivers.
• Communicate technical analyses and compliance evidence clearly to customers, suppliers and institutional stakeholders.

• Bachelor's or Master's degree in Aerospace, Space Systems, Mechanical or Electrical Engineering, or a related technical field.
• Several years of experience in spacecraft reliability, dependability, mission assurance, space safety or related satellite systems engineering.
• Hands-on experience with ESA, DLR or comparable institutional debris-mitigation and space-safety requirements.
• Practical experience performing debris, disposal or end-of-life analyses and producing the corresponding technical justification.
• Experience with DRAMA, SARA or equivalent space-safety analysis tools.
• Experience developing or reviewing quantitative spacecraft reliability or mission-lifetime assessments.
• Good understanding of spacecraft hardware, qualification, degradation mechanisms and redundancy.
• Good engineering programming skills, particularly Python.
• Ability to work with incomplete supplier data and develop defensible engineering assumptions, models and conclusions.
• Familiarity with ECSS dependability, qualification and space-safety standards and a pragmatic approach to applying them in a fast NewSpace environment.
• Strong written and verbal communication with engineering teams, suppliers and customers. English is our working language; German is an advantage.

Experience in one or more of the following is a strong advantage

• Experience supporting ESA/DLR reviews and closing institutional compliance requirements.
• Probabilistic reliability modelling, Monte Carlo methods or reliability block diagrams.
• Radiation reliability or EEE parts assurance.
• Definition or execution of lifetime, endurance or accelerated test campaigns.
• Reliability assessment of internally developed spacecraft hardware.
• Use of qualification results and accumulated flight heritage to improve reliability estimates.
• Familiarity with FMEA/FMECA, FTA and FDIR methodologies.
• Tailoring ECSS / ESA assurance processes to NewSpace development.
