Our spacecraft perform multiple orbital mission profiles and return safely to Earth through hypersonic atmospheric reentry and landing with pinpoint accuracy for rapid refurbishment and reuse.\nRole Description\nWe are looking for a Junior Avionics Engineer to join our avionics team and support the design, development, integration, and testing of avionics systems for our reusable orbital logistics vehicles.\nThe role covers avionics architecture, on-board computers, electronic hardware, EEE parts selection, harnessing, electrical and data interfaces, EGSE, and verification activities. The engineer will work closely with systems, GNC, software, mechanical, and AIT teams to develop reliable avionics solutions and support them from design through integration, testing, and qualification.\nThis role is suited for an early-career engineer with strong fundamentals, hands-on project experience, and clear motivation to work on spacecraft avionics.\nKey Responsibilities\nSupport avionics design, integration, and testing activities under the guidance of senior engineers.\nAssist with the development and review of electrical schematics, wiring diagrams, pinouts, and interface documentation.\nSupport harness design activities, including routing, connector selection, labeling, and continuity checks.\nAssist with the selection and documentation of electronic components, connectors, sensors, actuators, and EEE parts.\nSupport board-level bring-up, debugging, and validation activities for avionics hardware.\nParticipate in laboratory testing, functional testing, and system-level avionics test campaigns.\nSupport EGSE setup, configuration, operation, and basic troubleshooting.\nAssist with electrical and data interface verification between avionics units and spacecraft subsystems.\nPerform measurements and checks using laboratory equipment such as oscilloscopes, multimeters, power supplies, and logic analyzers.\nSupport environmental and qualification test preparation, execution, and post-test checks.\nDocument test results, non-conformances, and technical findings clearly and accurately.\nCollaborate with avionics, software, systems, GNC, mechanical, and AIT teams during integration and test activities.\nContribute to design reviews and test readiness reviews by preparing supporting material and technical inputs.\nRequired Qualifications\n0-1 years of professional experience in aerospace, electronics, avionics, or related technical fields.\nDegree in Electrical/Electronic Engineering, Aerospace Engineering, Telecommunications Engineering, or a related technical field.\nHands-on technical experience through participation in a rocketry team, Formula Student team, CubeSat project, robotics team, equivalent engineering club, or an applicable internship at a relevant aerospace company or startup.\nBasic understanding of electrical/electronic systems, circuits, sensors, actuators, and embedded hardware.\nBasic understanding of avionics systems, electrical interfaces, and spacecraft or aerospace electronics.\nExposure to electronic design, hardware integration, avionics testing, laboratory work, or system-level testing.\nFamiliarity with schematics, PCB basics, wiring diagrams, pinouts, connectors, and electrical documentation.\nBasic familiarity with communication protocols and interfaces such as CAN, UART, SPI, I2C, Ethernet, RS-422/485, or SpaceWire.\nBasic familiarity with laboratory equipment such as oscilloscopes, multimeters, power supplies, logic analyzers, or data acquisition systems.\nAbility to write clear technical documentation, test notes, procedures, and reports.\nStrong problem-solving skills and willingness to work hands-on during integration and testing activities.\nAbility to work effectively in multidisciplinary engineering teams.\nFull proficiency in English, written and spoken.\nPreferred Qualifications\nBasic exposure to aerospace industry standards such as ECSS, NASA, or MIL\nBasic proficiency with one or more programming languages such as Python and MATLAB.\nExperience in a startup, student team, laboratory, or small engineering team with fast design-build-test iterations.\nExperience with on-board computers, embedded hardware, sensors, actuators, harnessing, or communication buses.\nKnowledge of electrical CAD, PCB design, or harness design tools.\nExposure to EGSE, test automation, data acquisition, or laboratory instrumentation.\nExposure to environmental testing, EMC/EMI testing, vibration testing, or thermal-vacuum testing.\nBasic awareness of aerospace standards such as ECSS, NASA, or MIL.\nBasic awareness of EEE components, component selection, derating, availability, or reliability considerations.\nGood proficiency in Spanish\nWhat We Value\nExcellence in technical work, execution, and professional conduct\nStrong ownership mindset, with the ability to drive activities to clear outcomes through accountability, proactivity, and resourcefulness\nClear, efficient, direct, and constructive communication\nTeam-first attitude with low ego and strong cross-functional collaboration\nWhat We Offer\nLocation: Madrid, Spain (office-first)\nFlexible hybrid work (2 days/week from home + 2 fully
