Technical Sales SpecialistLocation: Los Angeles, CA · Full-time, on-site
The CompanyHeliofold US provides space-grade Colorless polyimide (CPI) ultra-thin cover glass (UTG) as a primary protection material for spacecraft solar arrays, delivering high power-to-weight performance for satellites in LEO, GEO, and deep-space missions. Our cerium-doped UTG delivers exceptional optical transmittance, minimal degradation under prolonged sun exposure, and high thermal stability, enabling thinner, lighter glass-on-cell protection without compromising radiation shielding or durability. Alongside UTG, we supply complementary space-PV materials, including SCPI film, HJT solar cells, and space-grade adhesives, supporting full-stack evaluation and next-generation solar array architectures. We work directly with spacecraft OEMs and solar array integrators to source, qualify, and deliver materials that make solar arrays lighter at launch, more compact when stowed, and longer-lasting on orbit.
The RoleAs our Technical Sales Specialist, you'll own the front line of Heliofold's growth: engaging spacecraft OEMs, solar array integrators, and industry partners, understanding their technical requirements, and proposing the right Heliofold materials for their mission. This is a full-time, on-site role based in the Los Angeles area, working closely with our engineering and technical support teams to move customers from first conversation to qualified, integrated product. It's a hands-on role for someone who wants to help shape how the next generation of solar arrays gets built, not just sell into it.
Your Mission- Manage the sales pipeline end to end, engaging spacecraft OEMs, solar array integrators, and other industry partners
- Deliver technical product presentations and translate customer requirements into the right materials solution
- Prepare quotations and proposals, and coordinate product evaluations and demonstrations
- Partner with engineering and technical support to answer customer questions, troubleshoot issues, and support successful integration of Heliofold products
- Maintain accurate CRM records so the pipeline stays visible across the team
- Represent Heliofold at industry events, gathering market feedback that sharpens our sales strategy and collateral
What You Bring- Proven experience in technical sales, ideally in aerospace, semiconductors, advanced materials, or another deep-tech sector
- Strong communication and customer service skills, with the ability to build relationships and present complex technical information clearly
- Comfort providing technical support: understanding specs, application requirements, and basic performance testing concepts
- Solid grasp of the B2B sales process, from prospecting and qualification through negotiation and close
- Bachelor's degree in engineering, physical sciences, business, or a related field (equivalent experience considered)
- Strong organizational and time-management skills to juggle multiple accounts and priorities
- Familiarity with CRM tools and standard productivity software
- Willingness to travel for customer visits and industry events
Nice to Have- Knowledge of space-qualified materials (GaAs, perovskites, CPI, UTG, cover glass, adhesives, composites)
- Experience with market research and competitive analysis
- Comfort working in a highly technical, fast-evolving environment alongside cross-functional teams
If you don't check every one of these boxes, apply anyway. We're a young, fast-moving materials company, and curiosity and follow-through matter more to us than a perfect resume match.
