Research Chemist - Polymers

Employment Type: Full-time
Travel: Starpath develops and manufactures the technologies that will enable humans to live on the Moon and Mars. Today, we are building robotic systems that locally produce the essential commodities a lunar civilization will require at extreme scale: water, power, and oxygen. Polymer Chemist - Space Solar
Starlight manufactures the lowest cost and highest performance space solar ever, which will power the majority of new satellites built on Earth and all of Starpath's equipment on the Moon and Mars.
As a Polymer Chemist on the Starlight team, you will own the polymer materials, encapsulation systems, and barrier chemistries that protect our perovskite solar cells from the space environment. You'll drive the formulation, qualification, and integration decisions that determine how well our arrays survive moisture, oxygen, thermal cycling, UV, and radiation across years on orbit - while staying compatible with the underlying perovskite chemistry.
Develop, formulate, and qualify polymer encapsulants, edge seals, barrier films, and adhesives for perovskite solar hardware
Engineer moisture and oxygen barrier systems with ultra-low water vapor transmission rate (WVTR) and oxygen transmission rate (OTR) to protect perovskite cells
Drive root-cause investigations on bonding, outgassing, delamination, and ingress-driven degradation across manufacturing and qualification testing
Characterize polymer materials and bonded joints using techniques such as FTIR, DSC, TGA, WVTR/OTR, and lap shear/peel testing
Evaluate polymer and encapsulation performance under space environments - vacuum outgassing (ASTM E595), thermal cycling, UV, atomic oxygen, and ionizing radiation
Translate bench chemistry into stable, high-yield production processes in partnership with cell, panel, and manufacturing engineering
Push back on unnecessary complexity - simplify chemistries, reduce cure times, and cut overhead wherever it doesn't add value
Master's or PhD in polymer chemistry, chemistry, materials science, chemical engineering, or a related discipline

• 3+ years of hands-on experience with polymer encapsulants, adhesives, or barrier films for sensitive optoelectronic or electronic devices (graduate research applicable)
• Demonstrated ability to connect polymer chemistry and processing to device-level reliability outcomes

PhD in a relevant discipline with a focus on encapsulation, barrier materials, or polymer chemistry for optoelectronic devices
Direct experience formulating or qualifying encapsulation systems for moisture- and oxygen-sensitive devices (perovskite PV, OLED, OPV, or flexible electronics)
Hands-on experience with ultra-low WVTR/OTR barrier materials, including multilayer and inorganic-organic hybrid barrier stacks
Experience with surface preparation, adhesion science, and bond strength testing
Knowledge of space-grade material requirements - low outgassing (ASTM E595), UV stability, atomic oxygen resistance, and radiation tolerance
Experience scaling polymer processes from bench to high-rate production
