JOB SUMMARY

Key Responsibilities:

Product Strategy & Ownership

• Define and own the product roadmap for 3D-printed spacecraft components
• Translate customer needs into clear product requirements and specifications
• Serve as product owner, aligning engineering, manufacturing, and business teams
• Identify and prioritize adjacent product opportunities beyond the initial propellant tank

Technical & Performance Definition

• Establish key performance metrics (KPPs/KPIs) including mass efficiency, pressure capability, reliability, manufacturability, and cost
• Define performance, cost, and schedule targets aligned with market needs and business goals
• Partner with engineering to ensure designs meet mission and business requirements

Business Model & Economics

• Develop and maintain the product business case, including:
• Unit economics and cost models
• Pricing strategy
• Volume assumptions and scaling scenarios
• Evaluate make vs. buy, vertical integration, and supply chain strategy

Go-to-Market & Customer Engagement

• Develop and execute the go-to-market strategy
• Work closely with sales to:
• Identify target customers (satellite OEMs, propulsion providers, primes)
• Support capture efforts and proposals
• Engage directly with customers to refine requirements and validate product-market fit

Differentiation & Market Positioning

• Define the competitive positioning of the product
• Identify and articulate differentiators (e.g., performance, cost, lead time, integration, reliability)
• Monitor competitors and industry trends in additive manufacturing and spacecraft hardware

Program Execution Support

• Align cross-functional teams around milestones, deliverables, and priorities
• Track progress against cost, schedule, and technical goals
• Support risk identification and mitigation strategies

Required Skills and Experience

• Demonstrated ability to work across engineering and business functions
• Strong analytical skills, including cost modeling and trade studies
• Experience translating technical systems into customer-facing value propositions
• Proficient in the use of Microsoft Word, PowerPoint and Excel
• Ability to work independently.
• Ability to work in multi-disciplinary teams
• Excellent technical communications skills.
• Good written and verbal communication skills.

Desired Skills and Experience:

• Experience with additive manufacturing (metal AM strongly preferred)
• Background in spacecraft or launch vehicle development
• Familiarity with qualification and certification of aerospace hardware
• Experience in a startup or fast-paced development environment

Key Traits for Success

• Technically credible with engineers; can go deep when needed
• Commercially minded; understands how products win in the market
• Comfortable with ambiguity; able to build structure from scratch
• Strong communicator across technical and non-technical stakeholders
• Bias toward ownership and execution

Education & Work Experience:

• Bachelor’s degree in Mechanical Engineering or related field
• MBA or equivalent business experience (a plus, not required)
• 5+ years of experience in aerospace, ideally with exposure to:
• Spacecraft propulsion systems

Why This Role Matters

This role will define not just a single product, but the foundation of a scalable product line in 3D-printed spacecraft hardware. You will directly shape how advanced manufacturing translates into real, adopted space systems.
