Satellite Reliability & Space Safety Engineer (all genders)

About the Position

Join the next generation of satellite development in Germany!

At Reflex Aerospace, we develop high-performance satellites with a strong focus on fast, payload-centric development and increasing vertical integration. As our missions grow more complex and fly for longer, demonstrating that our satellites can reliably complete their missions and meet applicable space-safety requirements is becoming increasingly important. We are looking for an engineer with strong experience in spacecraft reliability, mission lifetime, and space-debris compliance who can bring these capabilities into our NewSpace development environment.

At Reflex, we combine rigorous engineering practices with the agility and efficiency of NewSpace development. We follow applicable industry standards and regulatory requirements, while promoting practical, solution-oriented approaches that support both mission reliability and efficient development.

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.

Responsibilities

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.

Requirements

• 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.

Nice to Have

• Experience supporting ESA/DLR reviews and closing institutional compliance requirements.
• Probabilistic reliability modeling, 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.

We Offer

• Work directly on complete satellite systems and products, with significant technical ownership from early design through qualification and operations.
• Help establish engineering capabilities used across multiple Reflex satellite missions and product lines.
• Work closely with specialists across Systems Engineering, AIT, software, electronics, structures, thermal, AOCS, and power.
• Enjoy 30 days of paid vacation and a special company holiday on April 12th, celebrating the International Day of Human Space Flight and the spirit of exploration.
• We provide a hybrid work model along with flexible working hours, empowering you as the owner of your time management.
• An annual training budget of 1.500€.
• A contribution to your Urban Sports membership as well as a discount on public transportation.
• A 20% contribution to your private pension plan.
• Access to Corporate Benefits - a website with many discounts for various brands.
• We exclusively offer permanent employment contracts, reflecting our commitment to building long-term relationships and supporting sustainable career growth within our organization.
