About Us
At CosmoChute, we are building modular, reusable lunar robotics infrastructure for long-duration planetary operations. Our systems combine mobility, modular payload deployment, survivability through lunar nights, and repairability to make sustained presence on the Moon economically viable. We're a deeply technical, fast-moving team that believes in real ownership, real trust and in creating an environment where your best work matters.

Your Role
We're looking for a hands-on Senior Mechanical Engineer to join our core engineering team. You'll work across the full mechanical development lifecycle, from concept and design through analysis, fabrication, integration, and test, on our lunar rover and surface systems. This is a generalist role where you'll be expected to own problems end-to-end, context-switch across subsystems, and make good engineering decisions rapidly. You will contribute to systems such as:

Modular lunar rover platform
Payload deployment and transport systems
Bogie and wheel systems for extreme terrain
Structural assemblies and thermal-mechanical interfaces
Dust mitigation and survivability mechanisms
Repairable and modular robotic architectures

This role is best suited for someone who enjoys building from first principles, prototyping rapidly, and solving unconventional engineering problems under real constraints.

Your Responsibilities
Design and develop mechanical systems, assemblies, mechanisms, harness routing designs, and thermal interfaces for lunar robotics

Collaborate closely with systems, electronics, and software engineers in integrated teams
Develop and maintain CAD models and engineering drawings to space-grade standards
Contribute to mission-level trade studies and system-level design decisions
Run or oversee structural, vibration, and thermal analysis and interpret results to drive design decisions
Interface with external vendors, fabricators, and test facilities
Contribute to design reviews and technical documentation
Support integration, assembly, and test campaigns

Requirements

Must have

Bachelor's or master's degree in Mechanical engineering, Aerospace Engineering, Robotics, or related field.
Experience of 5+ years in the same domain.
Strong CAD skills (SolidWorks, CATIA, or similar)
Understanding of mechanisms, structures, materials, and manufacturing processes
Experience with prototyping and hardware development
Familiarity with tolerance stack-up, fasteners, bearings, gear systems, and actuator integration and GD&T in compliance with ASME Y14.5 standards.
Ability to work independently in fast-moving development environments
Strong problem-solving mindset and engineering intuition

Good to have

Experience with robotics, rovers, drones, automotive, aerospace, formula racing or mobility systems
Knowledge of FEA and simulation tools (ANSYS, SolidWorks Simulation, etc.)
Exposure to thermal systems or vacuum-environment design
Experience with composites, lightweight structures, or space-grade materials
Familiarity with environmental testing and reliability engineering
Experience in working with either of, ECSS, ISO, NASA, GEVS or similar standards for design, development and/or verification

What we deeply value

Curiosity and ownership
Ability to learn quickly across disciplines
Practical engineering judgment and first principles thinking
Profound mutual respect among co-workers
Willingness to prototype, fail, iterate, and improve

Benefits

What we offer

Competitive compensation
Equity participation
Meaningful long-term growth potential
Complete honesty with only legally required abstractions
