Principal Manufacturing Engineer (Thermal Protection Systems)

About Varda Low Earth orbit is open for business. Varda is accelerating the development of commercial space infrastructure, from in-orbit pharmaceutical processing to reliable and economical reentry capsules. Varda's W-Series vehicles are built, designed, and operated by Varda in‑house, including the pharmaceutical processing payloads, the capsules, the C-PICA heat shields, and the satellite buses. From life‑saving pharmaceuticals to more powerful fiber optics, there is a world of products used on Earth today that can only be manufactured in space. Varda is accelerating innovation in the orbital economy by creating both the products and infrastructure needed so space can directly benefit life on Earth. Our mission is to expand the economic bounds of humankind. Our team is uniquely suited to accomplishing this goal, with leadership and staff comprised of veterans from SpaceX, Blue Origin, major pharmaceutical companies and Silicon Valley. Varda was founded in January 2021 by Will Bruey and Delian Asparouhov with significant backing from world class investors including Khosla Ventures, Lux Capital, Founders Fund, Caffeinated Capital, General Catalyst, and Also Capital. Varda is headquartered in El Segundo, California, where we have offices and a production facility where our vehicles, equipment, and materials are built, integrated, and tested. Varda also has offices in Washington, DC and Huntsville, AL. Join Varda, and work to create a bustling in‑space ecosystem. About This Role As the Principal Manufacturing Engineer - Thermal Protection System (TPS) at Varda, you will own the manufacturing processes for the ablative and insulative materials that protect our reentry capsules during the most demanding phase of the mission- reentry. TPS manufacturing is one of the most technically specialized disciplines in aerospace, requiring deep expertise in ablative material processing, bonding, tiling, and surface preparation. You will develop and maintain the processes that ensure every capsule's heatshield is built to survive reentry conditions, working at the frontier of materials science and production engineering. This is a rare opportunity to own a critical, high-visibility manufacturing domain at a company that is already demonstrating reentry capability on orbit. This role is open at the L2 and Senior level, with levels determined based on candidate experience. Responsibilities Own manufacturing processes for thermal protection system production: ablative tile/panel preparation, bonding, densification, and closeout operations Develop and maintain detailed work instructions, process travelers, and process specifications for all TPS fabrication and installation operations Implement surface preparation, adhesive application, and cure cycle procedures that meet TPS bond strength and thermal performance requirements Collaborate with TPS design engineers to provide DFM feedback on tile geometry, bond joint design, and tooling access for installation Define inspection and verification methods for TPS bonds, surface finish, and dimensional conformance; integrate quality gates into production workflows Lead root cause analysis and corrective actions for TPS non-conformances, including bond voids, tile cracking, and surface contamination findings Develop and control environmental conditioning requirements (temperature, humidity) for TPS materials storage and processing areas Assess and procure TPS-specific tooling: bonding fixtures, tile templates, surface preparation tooling, and handling equipment Basic Qualifications B.S. in Materials Science, Mechanical, Aerospace, Chemical, or Manufacturing Engineering, or a related discipline, with consideration given to equivalent professional experience (typically 6-10+ years) 6+ years of manufacturing experience with thermal protection systems, composite materials, or advanced material bonding in aerospace or defense Hands‑on experience with ablative or reusable TPS materials: PICA, AVCOAT, SLA‑561, cork composites, ceramic tiles, or equivalent Experience with adhesive bonding processes, surface preparation methods, and cure cycle control for structural or TPS bonds Ability to read and interpret engineering drawings and TPS assembly models; familiarity with GD&T as applied to complex surface geometries Experience writing and maintaining manufacturing process documentation for specialized materials operations Must be physically able to regularly lift 25 lbs., bend, stoop, and stand for extended periods while working directly with hardware Preferred Skills and Experience Direct experience manufacturing TPS for reentry vehicles, hypersonic glide vehicles, or planetary entry capsules Familiarity with TPS inspection methods: visual inspection, tap testing, NDE methods applicable to bonded ceramic or ablative tiles Knowledge of TPS material properties - ablation rates, density gradients, outgassing behavior - and their manufacturing implications Experience #J-18808-Ljbffr vardaspace
