Senior Solar Process Engineer

About the role

K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by $450M from leading investors including Altimeter Capital, Redpoint Ventures, T. Rowe Price, Lightspeed Venture Partners, Alpine Space Ventures, and others – with an additional $500M in signed contracts across commercial and US government customers – we’re mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space.

The rise of heavy-lift launch vehicles is shifting the industry from an era of mass constraint to one of mass abundance, and we believe this new era demands a fundamentally different class of spacecraft. Engineered to survive the harshest radiation environments and to fully capitalize on today’s and tomorrow’s massive rockets, K2 satellites deliver unmatched capability at constellation scale and across multiple orbits.

With multiple launches planned through 2026 and 2027, we're Building Bigger to develop the solar system and become a Kardashev Type II (K2) civilization. If you are a motivated individual who thrives in a fast-paced environment and you're excited about contributing to the success of a groundbreaking Series C space startup, we’d love for you to apply.

The Role

The processes that go into developing K2's solar arrays — from module interconnects and adhesive systems to cover glass coatings and substrate composites — directly determine how much power they produce, how long they last, and how fast we can build them. Getting the process engineering right is not a support function here; it is on the critical path.

You will develop, qualify, and optimize manufacturing processes for K2's solar array systems. The operating environments, mission lifetimes, and production rates we are pursuing demand meaningful impact in how our materials are characterized, qualified, and manufactured. You will own the execution of process development for material systems and novel manufacturing processes as we scale K2's solar array design into production.

Responsibilities

Responsible for the development, qualification, and production-scale optimization of K2 solar array processes — including solar module interconnects, bonding, sintering, lamination, deposition, coating, bonding, mechanism joints, and surface treatment

Research, evaluate, and support selection of conventional and novel processes for solar array applications, contributing to trades that balance performance, manufacturability, cost, reliability, and schedule

Design and execution of structured DOE and statistical analyses to diagnose manufacturing problems and validate corrective actions

Use a first-principle, physics-based characterization across production processes to identify sources of variation and opportunities for yield improvement

Lead failure analysis, defect characterization, and root causes investigations for process related anomalies

Establish and drive corrective action plans back into design requirements and production

Own the evaluation, cost/benefit analysis, and selection of manufacturing equipment for all in-house process development

Collaborate with the production team to develop process specifications, work instructions, in-process checkouts, and end-of-line tests

Define qualification criteria, test envelopes, and characterization campaigns to establish resultant performance across radiation, thermal cycling, mechanical, and plasma environments

Partner with solar structures/mechanisms, thermal, avionics, and production teams to define manufacturing process-driven requirements, integrated qualification/acceptance testing, and on-orbit data review

Mentor junior engineers on process engineering fundamentals and solar array manufacturing best practices

Qualifications

Bachelor's degree in materials science, mechanical engineering, chemical engineering, physics, aerospace engineering, or a related technical discipline

5+ years of experience in materials and process engineering, with a strong foundation in materials science and engineering principles

Hands-on experience with material characterization, testing, and process development for hardware applications

Nice to Have

Master's degree or PhD in materials science, chemical engineering, or a related field

Prior experience developing and qualifying manufacturing processes for solar array systems across the full development lifecycle — requirements definition, trade studies, development testing, qualification, production, and on-orbit data review

Hands-on experience across multiple solar array material systems, with variation in cell technology, interconnect methodology, encapsulant chemistry, and system architecture

Deep working knowledge of adhesive systems, composites, thin films, thermal interface materials, and coatings as applied to high-power, long-life solar array hardware

Working knowledge of AIAA S111/S112, SMC-S-016, NASA-STD-4005, NASA-STD-5017, and NASA-STD-6016 for solar module qualification, materials usage, and spacecraft charging effects

Understanding of radiation effects on solar cell and module materials — displacement damage dose modeling, ionizing effects, UV degradation, and atomic oxygen erosion

Depth across solar process disciplines including deposition techniques for anti-reflective coatings, chemical etching for bond preparation, encapsulant deposition, methods for corrosion control, outgassing compatibility, descriptive and inferential statistics, and failure analysis

Hands-on proficiency with material characterization tools: SEM, EDS, FTIR, DSC, TGA, XRD, or equivalent

Experience scaling manufacturing processes from prototype to high-rate production, including SPC implementation and manufacturing equipment qualification

Python or MATLAB proficiency for test data analysis and degradation modeling

Compensation and Benefits:

Base salary range for this role is $140,000 - $175,000 + equity in the company

Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level

Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks

If you don’t meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other and non-traditional career twists and turns are encouraged!

If you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know.

Export Compliance

As defined in the ITAR, “U.S. Persons” include U.S. citizens, lawful permanent residents (i.e., Green Card holders), and certain protected individuals (e.g., refugees/asylees, American Samoans). Please consult with a knowledgeable advisor if you are unsure whether you are a “U.S. Person.”

The person hired for this role will have access to information and items controlled by U.S. export control regulations, including the export control regulations outlined in the International Traffic in Arms Regulation (ITAR). The person hired for this role must therefore either be a “U.S. person” as defined by 22 C.F.R. § 120.15 or otherwise eligible for a federally issued export control license.
