Systems Engineer

Ready to take your career stratospheric?

AALTO is a global leader in the stratosphere. We design, manufacture and offer Earth observation and connectivity services using our record-breaking Zephyr High Altitude Platform Station (HAPS) solar-electric unmanned aircraft, capable of staying in the stratosphere for days, weeks, and months at a time.

Powered entirely by the sun, Zephyr operates above 60,000 feet, high above conventional air traffic. As a new layer in Earth observation and connectivity ecosystems, Zephyr is positioned between satellites and more conventional terrestrial assets – filling in the operational gap between the two layers, while remaining a complementary solution capable of working in a system of systems.

Services delivered with Zephyr can empower government and commercial customers with capabilities to see and sense or connect from the stratosphere – making a meaningful impact on the ground, from the skies.

Join #TeamAALTO as we create this new, up-and-coming frontier, and be a part of a highly skilled, innovative and passionate group of people working together to make sure “the future is stratospheric.”

Job Purpose

We are seeking a Systems Engineer to join the team leading the development of the Zephyr High-Altitude Platform Station (HAPS). In this role, you will play a key part in designing, developing, and integrating software systems—focusing on ground control and onboard software to enable seamless communication, control, and mission execution. You’ll work closely with cross-functional teams to deliver robust, scalable, and compliant software solutions that meet high standards for performance, safety, and regulatory compliance

Key Responsibilities

• Lead the integration of onboard and ground-based software systems, including Flight Management Systems (FMS), Flight Deck interfaces, and mission control applications.
• Design and implement ground systems for UAV control, including datalink management, Satcom Systems, network routing (TCP/UDP), and real-time telemetry processing.
• Define and integrate the Flight Management System (FMS) capabilities tailored for long-endurance UAV operations, including autonomous navigation, mission planning, and contingency handling.
• Develop and refine intuitive HMI solutions for UAV operators, ensuring situational awareness, mission control, and safety-critical feedback through user-centered design principles. This includes developing interfaces for mission planning, flight control, and telemetry visualisation.
• Establish and maintain software architecture for mission-critical systems, ensuring modularity, scalability, and fault tolerance.
• Gather, evaluate, and manage software requirements to ensure they are traceable and consistently aligned with overarching system goals.
• Conduct and contribute to software-focused design reviews (SRR, PDR, CDR), ensuring alignment with system architecture and mission needs.
• Develop and execute software verification and validation plans, including simulation, hardware-in-the-loop (HIL), and system-level testing.
• Ensure software systems comply with aviation standards such as ARP4754A, ARP4761 and DO-178C and support certification efforts.
• Identify and mitigate software-related risks, including cybersecurity, data integrity, and operational reliability.
• Act as a liaison between software teams and systems engineering, ensuring cohesive integration across avionics, payload, and ground systems.
• Maintain comprehensive documentation of software designs, test results, and integration procedures.
  
  

Experience And Qualifications

• Proven experience in software systems engineering, preferably in aerospace or UAV domains.
• Bachelor’s or Master’s degree in Software Engineering, Computer Science, or related field.
• Hands-on experience with onboard software development and ground control systems.
• Proficiency in network protocols (TCP, UDP), datalink technologies, and real-time systems.
• Familiarity with ARINC 661 standards for cockpit display systems is highly desirable, along with experience using OpenGL or similar graphics libraries for rendering real-time visual interfaces.
• Familiarity with aviation standards (DO-178C, DO-254, ARP4754, ARP4761).
• Experience with Systems Engineering tools (e.g., JAMA, IBM DOORS) and MBSE methodologies (desirable).
• Knowledge of UAV operations, safety standards, and regulatory frameworks.
