Arquiteto de Sistemas - Equipa de Inovação

Job Description

As the technological spin-off of Solar Impulse, the first electric airplane to fly around the world, the mission of H55 is to make aviation clean, safe, and affordable. H55 exists to accelerate this transition by building the certification-grade energy platform that electric aviation needs to scale, delivering energy storage systems that are predictable, provably safe, and trusted by authorities, insurers, and OEMs. Because in aviation, innovation only matters when it can fly.

At H55, you will work with a forward-looking team shaping the future of air transportation. Our team brings together experienced engineers, entrepreneurs, and industry experts who combine creativity, innovation, and strong technical expertise.

We believe that diverse perspectives lead to better engineering and stronger teams, and we are committed to building an inclusive workplace.

Your Role

As part of the Innovation Team, you will define and develop system architectures for next-generation electric aviation technologies.

You will translate high-level objectives into coherent system architectures, ensuring integration across electrical, thermal, software, and mechanical domains.

Your work will directly shape how future electric propulsion and energy storage systems are designed, integrated, and brought toward certification.

You will play a key role in structuring complex systems, evaluating technical trade-offs, and guiding multidisciplinary teams during early-stage development.

Main Responsibilities

• Define system architectures for electric propulsion, energy storage, and associated subsystems
• Translate high-level objectives into structured system architectures and technical solutions
• Develop system breakdown structures, functional architectures, and interface definitions
• Perform architecture trade studies to evaluate design options and emerging technologies
• Identify key technical risks and system-level constraints and propose mitigation strategies
• Ensure consistency and integration across electrical, thermal, software, and mechanical domains
• Guide engineering teams during concept development and early design phases
• Support the development of system models, simulations, and performance assessments
• Contribute to technology roadmaps and innovation strategy
• Support prototype and demonstrator development by ensuring system-level coherence

Your Profile

• MSc or PhD in Aerospace Engineering, Systems Engineering, Electrical Engineering, or a related field
• Strong experience in system architecture and complex system design
• Ability to build system architectures from high-level objectives or early requirements
• Experience working in multidisciplinary engineering environments
• Knowledge of electric propulsion, power electronics, high-voltage batteries, data buses, or thermal systems is a strong asset
• Familiarity with system modelling tools or MBSE approaches is a plus
• Strong analytical and problem-solving skills with the ability to evaluate technical trade-offs

What We Offer

• The opportunity to work on cutting-edge electric aviation technology with real-world impact
• A collaborative, international, and purpose-driven team
• Opportunities to grow into technical or leadership roles
• A flexible and supportive work environment
• An exceptional work location in Sion, Valais, in the heart of the Swiss Alps

You will have a direct impact on our products and on how we design and build them, working closely with cross-functional teams in a fast-evolving environment.

We are building a team where diverse perspectives are essential to solving complex engineering challenges and delivering safe, certifiable systems. If this role excites you but you don't tick every box, we encourage you to apply.
