Job Summary

R&D Engineer

Full-Time Onsite (Bay Area California)

Were hiring an R&D Engineer for a mission-driven clean energy startup developing next-generation perovskite-based tandem solar technology. Ideal for scientists and engineers who thrive in experimental environments and want to contribute directly to breakthroughs in solar efficiency stability and manufacturability.

Role Overview

Youll play a central role in developing thin-film materials processes and metrology for high-performance perovskite tandem solar cells. Your work will focus on identifying limitations within the current device stack designing strategies to overcome them and driving systematic experiments to optimize scalable deposition processes. Youll collaborate closely with scientists engineers and technicians while taking ownership of critical deposition tools characterization workflows and metrology techniques.

This role is high-impact and hands-on bridging fundamental R&D with future gigawatt-scale manufacturing readiness. Youll help develop unit process specifications qualify materials and generate insights that directly influence device architecture and long-term reliability.

What Youll Do

Develop and optimize thin-film deposition processes for key layers in the tandem solar stack
Identify shortcomings in existing materials or device layers and design strategies to improve performance
Perform systematic experiments to evaluate materials deposition parameters and process scalability
Use advanced metrology techniques (XRD XRF PL JV etc.) to characterize thin films
Maintain calibrate and train team members on deposition and characterization tools
Support development of process specifications for high-reproducibility manufacturing-ready materials
Collaborate with chemical suppliers to evaluate and qualify new materials
Contribute to designing or modifying materials to enhance stability efficiency or manufacturability
Work cross-functionally across R&D process engineering and manufacturing teams

Requirements

Ph.D. in chemistry materials science physics or related field; or masters degree with 2 years of relevant R&D experience
2 years of experience in thin-film deposition and characterization
Strong proficiency with metrology techniques such as XRD XRF PL JV and related methods
Ability to independently drive open-ended experimental programs
Motivation to contribute to climate and clean energy impact
Expert knowledge of metal halide perovskite materials and characterization

Nice-to-Haves

2 years of experience with vapor deposition of functional materials
2 years of experience in thin-film production PV semiconductor or similar environments
Strong understanding of solar cell physics and device chemistry
Experience developing or optimizing scalable reproducible unit processes

Why This Role

Work with purpose: contribute to next-generation solar technology with global impact
Be part of an innovative team pushing the boundaries of clean-energy materials
Excellent benefits including healthcare coverage 401(k) match commuter benefits and equity
Strong professional development support including conferences and training opportunities
