Mechanical Engineer (Mid-Sr)

At Stoke, we believe a thriving space economy will enable a vibrant, sustainable, and equitable future here on Earth. That is why we’re building Nova, our fully and rapidly reusable launch vehicle. Designed for daily flight, Nova tackles the core challenges of space transportation by reducing cost, increasing availability, and improving reliability. By radically lowering launch costs and increasing flight cadence, we’re helping create a truly scalable space industry.

Our team is mission-driven, collaborative, and empowered to take ownership of their work. If you want to work alongside some of the most dedicated and talented people on Earth, we’d love to have you join us.

Description

We're looking for Mechanical Engineers with rock-solid fundamentals and a bias for action. You'll own hardware from blank sheet through flight—designing, analyzing, building, testing, and integrating critical rocket systems including vehicle primary structures, fluids and avionics component packaging, and secondary structures. This is a high-ownership, hands-on role where you'll tackle new problems daily, work across disciplines, and be expected to figure out solutions on the fly. If you thrive on hard problems, moving fast, and seeing your hardware perform, this role is for you.

Responsibilities

• Own mechanical and structural hardware from concept through flight operations
• Design and analyze structural components, fluids and avionics component packaging, and vehicle integration hardware
• Perform structural and thermal analysis using hand calculations and FEA—choosing the right tool for the problem at hand
• Write margin summaries; may involve developing loads or load cases
• Create CAD models and manufacturing drawings with proper GD&T
• Work directly with machinists, welders, and technicians to build and test your hardware
• Procure parts, manage suppliers, and keep your hardware on schedule and on budget
• Troubleshoot failures, disposition non-conformances, and drive root cause corrective action
• Test and improve your hardware —vibration, thermal, structural, pressure
• Lead design reviews and communicate technical decisions clearly
• Continuously improve designs to reduce cost, increase reliability, and improve manufacturability
• Failure analysis of components as it relates to thermal, loads, vibration, and shock

Minimum Qualifications

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related technical field
• 2+ years of hands-on engineering experience designing, building, and testing hardware
• Exceptional command of mechanical engineering fundamentals (statics, dynamics, mechanics of materials, heat transfer, fluid mechanics)
• Proficiency with 3D CAD (NX preferred) and creating detailed manufacturing drawings
• Working knowledge of GD&T per ASME Y14.5
• Experience with structural analysis—both hand calcs and FEA
• Strong understanding of manufacturing processes (machining, sheet metal, welding, additive manufacturing)
• Proven ability to take ownership, work independently, and deliver results
• Excellent problem-solving skills and willingness to tackle unfamiliar challenges
• Strong communication skills—you can explain complex problems simply

Preferred Qualifications

• Experience with NX and ANSYS (or similar tools)
• Background in aerospace, automotive, or other high-performance hardware
• Familiarity with launch vehicles, propulsion systems, or cryogenic systems
• Experience designing for extreme environments (thermal cycling, vibration, shock, vacuum)
• Hands-on experience with test campaigns—developing test plans, instrumentation, running tests, analyzing data
• Exposure to avionics integration, harness routing, or electronics packaging
• Experience in fast-paced startup or rapid development environments
• Track record of shipping hardware from first principles through production

Benefits

• Equity – We are pleased to offer equity in the form of stock options to all regular, full-time employees.
• Comprehensive benefits program including subsidized medical, dental, and vision insurance
• Company-paid life and disability insurance
• 401(k) plan with employer match
• 4 weeks’ Paid Time Off
• Holidays – 10 days (including an end-of-year closure)
• Paid Family/Parental Leave
• On-site gym or monthly wellness stipend (depending on location)
• Dog friendly offices!

Compensation

Target Levels:

• Level 2 Range: $109,725 - $148,470
• Level 3 Range: $129,150 - $193,620
• Level 4 Range: $151,305 - $252,105

Our job posts are intentionally written to attract a wide variety of experience levels, and we make decisions about the right fit on a per-candidate basis.

Your actual level and base salary will be decided based on your specific experience and skill level.
