Job description

Transcelestials vision is to improve the connectivity experience for the next billion people. We believe that connectivity is a human right and Transcelestial is on a mission to solve the problem of internet distribution and provide affordable high-speed internet to everyone.

Transcelestials next‑generation wireless laser communication technology is one of the most effective solutions in the distribution of high‑quality high‑speed internet connectivity making it well poised to solve civilizations long‑term communication needs and ultimately improve connectivity for 1 billion users globally.

Highly reliable and secure its light‑weight shoe‑box sized CENTAURI device leverages its proprietary laser technology to create a wireless distribution network and can be quickly easily and cost‑effectively installed on any standard telecom pole or tower at a faster time‑to‑market than standard fiber‑optic cable.

Over the longer‑term Transcelestial aims to develop a constellation of small satellites positioned in Low Earth Orbit allowing their laser network to not only beam across cities but upwards to connect continents across the world too.

OUR VALUES

• Lean & Simple. Our products are simple to use we focus on what matters we solve issues one by one and we spend smart.
• Approachable. Whoever you are wherever you come from dont be shy! The best ideas can come from anywhere in the organisation.
• Supportive. We are a bunch of smart individuals delivering at their best working in teams. If you face an issue you can be sure someone will jump in and help you.
• End user obsessed. Customers and end users are at the core of everything we do.
• Relentless innovators. Our technology is at the forefront of innovation. We are curious we question everything we love research and are passionate about the next big thing.

Join our team if you want to define the rules of how our civilisation communicates!

Mechanical Design Engineer Space Laser Communications

The Mechanical Design Engineer at Transcelestial is responsible for the systems development for a novel miniature space‑based laser communication terminal. This position is part of the Space & Defense Team led by Dr. Jan Smisek ( This position will also interact with the rest of the hardware manufacturing and software design teams to assist with the overall development of the optical systems and new optical alignment technologies.

As Mechanical Design Engineer you will work on the following:

• Mechanical & Thermal Engineering Design and validate payload structures and interfaces through CAD modeling vibration analysis and thermal simulations to ensure performance and survivability in launch and space environments.
• Performance & Structural Analysis Define and evaluate the mechanical and thermal architectures of laser communication terminals focusing on pointing stability structural robustness and thermal control to meet mission requirements.
• Assembly Integration & Test (AIT) Develop and execute AIT plans and procedures conduct environmental qualification campaigns (vibration shock thermal vacuum) and oversee integration of laser communication terminals into host spacecraft.

What you will bring:

• Real experience with launching satellite platforms in space.
• Degree in Aerospace Mechanical or Electrical Engineering or equivalent work experience.
• 2 years of mechanical design and analysis engineering experience in satellite missions.
• Strong background in mechanical design vibration analysis and thermal simulations strongly applied to optical or space payloads.
• Experience with CAD tools (e.g. SolidWorks CATIA) for structural design for space platforms and interface development.
• Strong Communication Skills including proven ability to work autonomously while collaborating in international multidisciplinary teams.
• Strong general technical documentation and time management skills with a deep desire to fix things and optimize solutions

It is a bonus if you have:

• Full lifecycle experience on a satellite mission or space optical payload.
• Satellite or optical payload assembly integration and test (AIT) experience.
