Materials and Process Engineer

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 a Principal Materials and Process Engineer at Varda, you will have the opportunity to set the technical direction for materials and processes across the company as we scale from a few bespoke vehicles to many consistent, concurrent builds. This role is the recognized subject-matter expert for the special processes used on flight hardware, including ablative and thermal protection systems (TPS), coatings, polymers, composites, adhesives, wet chemical processing, corrosion control, and metallic structures. The Principal Materials and Process Engineer defines the standards, specifications, process qualifications, and control plans that Varda and its suppliers build to, and leads RCCAs, MRB, and failure investigations for the most critical material and process non-conformances. You will make sound decisions quickly without established infrastructure, influence material decisions owned by other teams, and hire and mentor engineers. You will also help build Varda's materials and processes function, including approved materials and processes lists, materials usage agreement processes, and in-house materials lab capability. Materials and Process Engineers are a vital part of increasing Varda's build cadence, working directly with design engineers, technicians, and suppliers across the full range of materials and processes required to manufacture our vehicles. The focus of the job is to implement incremental improvement for every vehicle Varda produces while establishing the standards that let the whole organization scale. Responsibilities

Develop, qualify, and maintain special processes for flight hardware, including ablative and thermal protection systems (TPS), coatings, polymers, composites, adhesives, and processes applicable to metallic structures

Develop and control wet chemical processes (cleaning, etching, passivation, conversion coating and similar).

Implement corrosion prevention and control practices, and assess chemical compatibility between materials, process fluids, and service environments

Design experiments, methodologies, and pathfinder hardware to de-risk processes, and characterize materials and processes through mechanical, thermal, chemical, and microstructural testing, and use statistical methods to define process windows

Define tooling, fixture, test equipment, cleanliness, contamination control, and material handling requirements for assigned processes and flight hardware

Develop and maintain Special Process Specifications, Process Qualification and Validation Records and Control Plans

Lead and contribute to RCCAs, MRB and failure review boards for material and process non-conformances, including corrosion, surface contamination, defects found in NDE, test, or inspection, failure analysis (fractography, metallography, SEM/EDS, chemical analysis) in-house or through partner labs.

Basic Qualifications

B.S. in Materials Science, Metallurgical, Chemical, Mechanical, or a related engineering discipline, or demonstrated equivalent experience and expertise.

6+ years of process and materials engineering experience in aerospace, semiconductor or another high-reliability industry.

Demonstrated record of developing and qualifying processes and materials for flight or safety-critical hardware, including first article builds and compliance with industry standards (AWS, AMS, ASTM or similar).

Experience authoring and releasing specifications, design guidance, acceptance criteria, and drawing callouts used by an organization and its suppliers.

Experience with thermal, chemical, mechanical, and NDE characterization, including interpreting results to define process windows.

Deep expertise in at least one area (ablatives and TPS, composites, polymers and adhesives, coatings and surface treatment, wet chemical processing and corrosion control, welding metallurgy, heat treat, additive, or NDE).

Experience with aerospace metals (stainless steel, aluminum, titanium, nickel alloys) and their processing, including heat treatment, welding and brazing, and finishing.

Experience with corrosion mechanisms (galvanic, crevice, pitting, stress corrosion, hydrogen embrittlement) and chemical compatibility of materials with process fluids and service environments.

Experience developing and controlling wet chemical processes, including bath chemistry, rins
