Senior Mechanical Engineer, Spacecraft Mechanisms

Employer description

Katalyst Description:

Katalyst is an American technology company focused on dynamic space operations.  We are building a fleet of dual-use multipurpose robotic space vehicles to create the future where maneuvering, upgrading, refueling, resupply and exploration are as routine as they are on Earth. Getting to space and overcoming the gravity well is only half the story. What you do there is the future. We are not building the trains. We are building the machines that lay down the tracks. By developing the foundational capabilities that make sustained, responsive operations possible, we enable a new era of space exploration that strengthens national security and ensures freedom of action in an increasingly contested domain.

Katalyst Culture:

Working at Katalyst is intense, hands-on, and deeply rewarding. You’ll take real ownership and see your work move from concept to operations in an environment where the problems are hard and the impact is real. We value humility, craftsmanship, and doing things the right way, even when it’s harder. You’ll work closely with thoughtful, driven teammates who push each other to do their best.  Oh, and we're dog friendly!  

Benefits:

• Stock options & equity
• Medical, dental, and vision coverage
• 401(k)
• Unlimited PTO
• Catered lunches

What You’ll Do 

• Tightly work with the NEXUS-1 spacecraft team to ensure the upgrade modules integrate smoothly to the spacecraft 

• Identify and analyze requirements, conceive and develop trade studies on mechanical systems. 

• Create and iterate detailed CAD models. 

• Create detailed 2D manufacturing drawings and perform tolerance stack-up analyses to ensure design intent 

• Develop and analyze kinematics, mechanism architectures, dynamic models, and equations of motion for deployable assemblies and in-space robotic systems. 

• Develop dynamic models and analyze dynamical systems for deployable assemblies and in-space robotic systems.Analyze structural integrity and performance of parts and assemblies using analytical methods and FEA tools. 

• Apply sound mechanical engineering principles to solve challenges involving load paths, stiffness, thermal effects, and vibration. 

• Participate in design reviews, failure mode analysis, and system-level integration. 

• Rapidly prototype and iterate on designs using additive manufacturing, machining, and other fabrication methods. 

• Interface with electrical, software, and systems teams to ensure mechanical solutions meet overall system requirements. 

• Support mechanical integration, testing, and troubleshooting of assemblies both in the lab and in the field. 

What We’re Looking For 

Required 

• 5–8 years of experience designing, modeling, developing, creating engineering drawings for, and flight-qualifying spacecraft mechanisms, assemblies, or payloads. 

• 3+ years experience running FEA analyses to assess vibration and shock loads for spacecraft or payloads. 

• Strong understanding of mechanics of materials, material failure modes, motors and electromechanical systems, lubrication and tribology, and associated analysis methods. 

• Familiarity with a wide set of manufacturing processes such as machining, welding, forming, and joining methods 

Your Ideal Background 

Preferred  

• Hands-on experience building, integrating, and testing robotic flight hardware 

• Experience with avionics, optics and harnessing 

• Experience in start-up environments with minimal oversight 

• Ability to think in a systems mindset and understand how one subsystem affects the others  

Additional Requirements: Must be willing to work extended hours and weekends as needed. 

Compensation and Benefits: Your base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience. The anticipated salary range for this role is $130,000 - $170,000 annually.

Base salary is just one part of your total rewards package at Katalyst. You will also be eligible for long-term incentives, in the form of the Employee Stock Option and Equity Plan, as well as a relocation bonus and other discretionary bonuses. You will also receive access to comprehensive medical, vision, and dental coverage, and unlimited Paid Time Off.

At Katalyst our work on projects involving the U.S. Department of Defense requires adherence to International Traffic in Arms Regulations (ITAR), 22 C.F.R. Parts 120-130, which requires compliance with U.S. export laws before allowing employees to perform certain positions. Currently, our available roles necessitate access to ITAR-controlled information, and as a result, Katalyst would have to ensure any non-US person is author...
