Technical Tools

EngineeringMechanical Engineer

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.

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!

✓Support spacecraft and payload mechanical layout from early concept through detailed design, integration, qualification, and flight, balancing packaging, mass properties, access, interfaces, manufacturability, and schedule.

✓Develop and maintain top-level CAD assemblies, vehicle envelopes, coordinate systems, keep-out zones, interface geometry, and configuration-controlled layouts that serve as the mechanical source of truth for cross-functional teams.

✓Design primary and secondary spacecraft structures, brackets, panels, decks, mounts, equipment supports, and mechanical interfaces using sound load-path, stiffness, strength, fatigue, thermal-distortion, and vibration principles.

✓Perform and review hand calculations and finite element analyses for static, modal, vibration, and shock environments; correlate models with test data and use results to drive design decisions.

✓Drive spacecraft packaging trades across avionics, harnessing, propulsion, GNC sensors, thermal hardware, payloads, mechanisms, and structures, resolving competing volume, access, field-of-view, center-of-mass, and integration constraints.

✓Partner closely with manufacturing and technicians to support prototype and flight builds, resolve drawing and fit issues, improve DFM/DFA, and ensure released designs can be assembled, inspected, serviced, and tested efficiently.

✓Contribute to design reviews, failure-mode analysis, mass-property tracking, configuration control, and flight-readiness decisions with clear, high-quality engineering documentation.

✓Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related technical discipline.

✓3-4 years of experience designing, packaging, analyzing, and releasing mechanical hardware for spacecraft, launch vehicles, aircraft, robotics, defense systems, or other high-reliability products.

✓Demonstrated proficiency with 3D CAD for complex assemblies and top-level layouts, including configuration management, interface definition, and detailed drawing release.

✓Strong mechanical fundamentals including statics, dynamics, mechanics of materials, load paths, stiffness, joints/fasteners, vibration, thermal effects, and material failure modes.

✓Experience performing hand calculations and structural analysis using FEA to assess static strength, modal behavior, vibration, shock, or related flight environments.

✓Ability to work across mechanical, electrical, avionics, GNC, propulsion, thermal, manufacturing, quality, and systems teams to resolve interface and integration issues.

✓Ability to thrive in a fast-paced, highly collaborative environment where ownership, iteration speed, craftsmanship, and sound engineering judgment are essential.

✓Experience developing spacecraft structures or payload mechanical systems through qualification and flight integration.

✓Experience owning spacecraft configuration/layout, mechanical architecture, equipment placement, or payload packaging on a tightly integrated vehicle.

✓Experience integrating avionics, harnesses, propulsion components, tanks, thermal hardware, GNC sensors, mechanisms, or payloads into constrained spacecraft volumes.

✓Experience in startup or rapid-development environments with minimal oversight and frequent design iteration.

✓Systems-level mindset and ability to understand how a mechanical layout decision affects thermal, electrical, GNC, mass properties, and operations.
