Systems Architect– Innovation Team, Sion

About H55 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.

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 aredesigned, 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
