Head of Avionics and Power Systems

ReOrbit

Helsinki, Finland

ReOrbit is looking for a Head of Avionics and Power Systems. In this role, you will lead the electrical, avionics, and power engineering teams responsible for the design, development, integration, and testing of satellite subsystems throughout the full satellite lifecycle.

You will manage a multidisciplinary team of digital, electrical, and power specialists, ensuring that satellite avionics and power systems perform reliably in the most challenging space environments while meeting demanding optimization requirements.

As a key technical authority within the spacecraft engineering organization, you will drive the development of avionics and electrical power subsystems in close coordination with other spacecraft subsystems, balancing performance, mass, volume, margins, and reliability against aggressive program schedules.

It's an exciting chance to join a dynamic start up, with the opportunity to make a real impact, to reach our goal of pushing the boundaries of space data transfer.

Responsibilities

• Participate in interdisciplinary trade off studies to define and optimize Electrical Power System (EPS) architectures tailored to specific mission profiles.
• Lead the team responsible for architecting Command & Data Handling (C&DH) subsystems, including unit selection appropriate for mission class and radiation environments.
• Recruit, mentor, and retain a high-performing team of hardware and firmware engineers, fostering a culture of technical excellence and rigorous design verification.
• Contribute to the implementation, improvement, and standardization of electrical and avionics design workflows and best practices.
• Manage departmental budgets, resource allocation, and schedule estimation across multiple concurrent flight programs.
• Oversee comprehensive verification campaigns, including Hardware in the Loop (HIL/FlatSat), functional and performance testing, and environmental testing (TVAC, vibration, shock).
• Lead root cause analysis and corrective actions for electrical and avionics anomalies identified during testing or on orbit operations.

Skills and Requirements

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related technical field.
• Master’s or PhD with a focus on Power Electronics, Avionics, or Space Systems is preferred.
• 10+ years of experience in the space industry, with a strong focus on satellite avionics and/or power systems for LEO and GEO missions, including satellites with a minimum mass of 300 kg.
• 5+ years of experience managing engineering teams, with a proven track record of delivering flight hardware on schedule.
• Demonstrated experience leading complex electronic systems from concept and design phases (PDR/CDR) through manufacturing, integration, and launch.
• Expertise in analog, digital, and mixed-signal circuit design and analysis, including high-reliability PCB layout.
• In depth knowledge of power subsystem sizing, solar array technologies, batteries, power conditioning, and power distribution units.
• Proficiency in circuit simulation, power budget analysis, and system-level trade studies.
• Familiarity with aerospace standards related to avionics and power systems, including NASA and ECSS standards.
