Join ReOrbit as Head of Avionics and Power Systems and take a leading role in shaping the future of satellite technology. In this position, you will lead a multidisciplinary team of digital, electrical, and power specialists, overseeing the design, development, integration, and testing of advanced avionics and power systems for satellites.

You will ensure these systems deliver reliable and optimal performance, even in the most demanding space environments, while meeting strict requirements for mass, volume, and efficiency. As a technical authority, you will collaborate closely with other spacecraft subsystems to balance performance, reliability, and aggressive program timelines.

At ReOrbit, you’ll have the opportunity to make a real impact in a dynamic startup environment, where innovation and ambition drive everything we do. This is your chance to push the boundaries of space data transfer and contribute to a mission that is redefining satellite technology.

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

• Degree in Electrical, Computer Engineering, or a related technical field.

• 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.

What does ReOrbit do?

ReOrbit builds the foundation for the next generation of space applications by transforming satellites into truly intelligent, interconnected platforms, defined by software. Our satellite design philosophy revolves around the idea that satellites must network, communicate with each other and thus improve mission efficiency. How can this be achieved? Thanks to a flexible software-first architecture, where all these aspects are dealt with upfront in the mission concept, as integrated functionalities.

ReOrbit’s top notch team of software engineers and system architects develop in-house software, procure hardware from the best-in-class suppliers, and seamlessly integrate the components to create flexible and secure satellites. Today, we are a rapidly growing company building a very strong multidisciplinary team to support our activities. We are headquartered in Helsinki, Finland with a subsidiaries in Bristol, UK and Bariloche, Argentina.
