Senior Mechanical & Structural Engineer (Satellite Platform)

Sateliot is a Barcelona-based satellite company with one goal: connect everything, everywhere. Founded in 2018, we've built the first satellite constellation that lets standard commercial devices communicate directly from space. Our technology bridges the gaps that terrestrial networks will never reach, bringing affordable and secure connectivity to industries, governments, and communities across the planet.

About The Team & This Role The Mission and Systems Engineering team is responsible for the design, integration and validation of Sateliot's satellite platform. As Senior Mechanical & Structural Engineer, you'll own the platform's structure end to end: the mechanical design and its configuration, the structural analysis behind it, the definition of the mechanical test campaign and the interpretation of its results, through to the flight model and launch. You'll consolidate the current design, take it through environmental testing with the AIT team, and lead the mechanical design of the next platform generations.

What You'll Do

• Own the structural and mechanical design of the satellite platform end to end: architecture, mechanical ICDs, drawings, configuration control.
• Own the platform's structural analysis: define the analysis plan, review and disposition results, run analyses when needed, and build Sateliot's in-house analysis capability (models, tools and processes).
• Own the mechanical verification of the platform: define test requirements, specify the vibration campaign, co-author procedures with the AIT team, supervise execution, and deliver the post-test engineering (model correlation, results assessment, non-conformance disposition).
• Take the structure from design to flight hardware: follow manufacturing and sourcing of structural components, support platform assembly and launcher integration with engineering judgement side by side with AIT.
• Lead the mechanical design of the next platform generations.

What you bring

• Degree in Mechanical or Aerospace Engineering with 8+ years of mechanical and structural engineering on spacecraft hardware.
• At least one satellite platform structure delivered end to end: design, structural analysis, manufacturing, AIT and environmental testing, through to launch.
• Hands-on mechanical design in CAD (SolidWorks or equivalent), including drawings and mechanical ICDs, on flight hardware.
• Hands-on structural analysis of spacecraft structures with an FEM tool (Nastran, ANSYS, Abaqus or equivalent), covering static, modal and random vibration.

Bonus if you have:

• Working knowledge of ECSS-E-ST-32 and ECSS-E-ST-10-03, or equivalent standards, applied pragmatically.
• Mechanisms and deployables.
• Micro-vibration for optical equipments
• MGSE design and cleanroom integration experience.
• Small-satellite launcher interface knowledge.
• Mechanical interfaces of propulsion subsystems.
• Thermo-elastic analysis.
• PDM/PLM tools.

Additional requirements

• Professional working proficiency in English.
• Based in Barcelona or willing to relocate: this is a hybrid role with regular on-site presence at our Barcelona HQ.
• Availability for travel to external test facilities and launch campaigns.

How we work We lead with humility, move fast, and take ownership. We collaborate without ego and measure ourselves by real impact, not titles or hierarchy. We hire people who already live these values.

What We Offer

• Real impact on one of Europe’s most ambitious space projects.
• Growth: we cover 50% of courses or master’s degrees (up to 5% of your salary), plus Spanish and Catalan classes.
• Health & balance: 50% on private health insurance and Urban Sports Club, a flexible schedule, and hybrid work, we focus on results, not hours.
• Flexible Compensation: flexible compensation through Cobee (meal, transport, kindergarten).
• A truly global team: 20+ nationalities building something genuinely new - and genuinely nice to work with. Great vibes, real teamwork.
• A real welcome: a dedicated buddy from day one.
• Life outside work: we organize leisure and sports activities both during and outside working hours - because great teams connect beyond the screen.
• Catering: if you don't have time to cook, we partner with a catering company so a fresh meal is sorted, no need to think about it.
• Parking: on-site parking at the office, with Sateliot covering 50% of the cost - plus free bike parking if you prefer to pedal in.
