We work at the intersection of mission design, flight dynamics, and systems engineering for commercial and institutional space missions. You will support our customers in defining missions, designing spacecraft architectures, and making the technical decisions that hold a programe together.
You will work closely with our flight dynamics team and bring the broader systems perspective that connects orbit design to spacecraft design to operations planning. The role spans customer-facing engineering services and internal product development.
This role grows into technical authority for customer programes as the portfolio expands.
WHAT YOU WILL WORK ON
System architecture definition and trade studies for satellite missions
Requirements derivation, management, and verification across subsystems
Coordination across propulsion, AOCS, power, thermal, and communications
Technical support to customers at design reviews and key programe milestones
System-level documentation and proposal writing
Bringing the systems engineering perspective to LEIA's product development
WHAT WE ARE LOOKING FOR
Mid-level candidate, 3–5 years of experience in space systems engineering or similarly complex engineering domains.
Experience from space systems development preferably on mission level
M.Sc. or PhD in aerospace engineering, physics, or equivalent
Understanding of the full mission lifecycle from concept through to operations
Familiarity with ECSS or similar standards
Ability to work across disciplines and communicate technical trade-offs clearly to non-specialists
Solid grounding in at least one spacecraft subsystem area — AOCS preferred
USEFUL BUT NOT REQUIRED
Experience with GEO telecommunications or electric propulsion missions
Background in AOCS, propulsion, or power subsystem design
Experience writing proposals for ESA or national space agencies
Familiarity with model-based systems engineering (MBSE) tools
REQUIREMENTS
Fluent in English; Swedish is a plus
EU or EES citizen
