About H55
H55 is the electric aviation pioneer born from Solar Impulse, the first aircraft to fly around the world on solar energy alone. Our mission is to make air transport clean, safe, and affordable by building the certification‑grade energy storage systems the industry needs to scale.
What we build is meant to fly. Not just prototypes, but certified systems that operate in real‑world conditions. That requires discipline across engineering, safety, and the way we run the business.
Based in Sion, Switzerland, with a growing international footprint, H55 is entering a pivotal new phase as we expand our operations and build the foundation for the next stage of electric aviation.
About the Role
We are looking for an IT Application Specialist with a strong foundation in system administration. As part of the IT team, you will be the go‑to person for keeping our business applications and web services running smoothly, from day‑to‑day operations to full software lifecycle ownership across the organisation.
You will ensure service continuity, manage user access, support end‑users, and contribute to IT projects. Your ability to document what you build and maintain will be as valued as your technical skills.
Main Responsibilities
Application & Web Services Management
Deploy and maintain on‑premise and cloud/SaaS applications, including ERP systems. Own the full software lifecycle: installation, configuration, updates, patching, and decommissioning. Manage API integrations, reverse proxy configurations (Nginx/Apache), and SSL certificates.
Database Administration
Manage SQL databases (MySQL, PostgreSQL, MSSQL), including backups, access rights, and day‑to‑day queries. This is not a dedicated DBA role, but confidence maintaining and querying databases is expected.
Identity & Access Management
Manage user identities and permissions through Active Directory, Azure AD/Entra ID, LDAP, and SSO. Enforce RBAC policies, manage groups, and conduct access reviews and audits.
Data Handling & Reporting
Handle data exports, basic ETL tasks, and reporting needs using Power BI or equivalent tools to support business operations.
User Support
Provide support for users and business applications. Manage tickets and requests through tools such as GLPI or Odoo.
Security & Monitoring
Monitor services, respond to incidents, apply security patches, and track vulnerabilities across the environment.
Documentation
Maintain up‑to‑date technical documentation, procedures, application catalogues (licences, versions, dependencies), and asset inventories.
Your Profile
Education & Experience
CFC, Bachelor’s degree in IT, or equivalent qualification
3+ years of experience in a similar role
Relevant certifications are a plus, including:
ITIL
Microsoft AZ-104
Linux LPIC‑1
Technical Skills
Experience deploying and maintaining on‑premise and SaaS applications throughout their lifecycle
Working knowledge of SQL databases, including backups, rights management, and basic queries
Familiarity with identity management technologies such as Active Directory, Azure AD/Entra ID, LDAP, and SSO
Ability to handle data exports, ETL processes, and reporting tasks
Experience with Odoo or similar ERP/business applications is an asset
Working knowledge of Linux and Windows Server environments, including installation, configuration, and troubleshooting
Understanding of web services infrastructure, including reverse proxies, SSL certificates, and API integrations
How You Work
Comfortable finding answers independently, reading technical documentation, and learning new technologies as the environment evolves
Service‑oriented, with clear communication toward non‑technical users
Strong documentation discipline: knowledge should remain documented and traceable within systems and procedures
Able to manage priorities and handle multiple workstreams within a small team environment
Structured, reliable, and attentive to operational detail
This role has a direct impact on how the company operates and scales. You will work closely with teams across the organisation and contribute to building a reliable, secure, and scalable IT environment that supports H55’s growth.
We are building a team with a range of backgrounds and perspectives, and we value people who bring different ways of thinking and working. If this role interests you but you do not meet every requirement, we encourage you to apply.
