About the role:

Thin films are micro- or nano-scale materials that enable many high-growth industries, including Lithium- and Zinc-based batteries, solar cells, carbon sequestration and conversion technologies, optical devices, quantum devices, displays, adhesives, medical implants, semiconductors, packaging materials, and many others. SirenOpt makes a real-time sensing and software platform to improve manufacturing yield and performance of thin film products.

The sensor is enabled by low-temperature plasmas and can collect multiple thin film property measurements (such as thickness with a precision of 1/10th of a nanometer, density, resistivity, chemical composition, and contaminate identification) in parallel and in real-time, thus allowing for the collection of critical data that is otherwise unobtainable. The optimization-based decision-making software uses the data from the sensor to accelerate R&D and process optimization, improve quality control, and enable real-time process control.

We are looking for a highly motivated Lead Mechanical Design Engineer to help us deliver a sensing and software platform that can be scalably integrated inside high-volume thin film manufacturing lines. As an early-stage member of the SirenOpt team, you will be able to make a real impact on next-generation thin film technologies and help build a solid technical foundation upon which a small company can grow. The ideal candidate will learn new concepts quickly and take pride in the quality of their work. We expect that you will be able to apply sound engineering judgment to solve a wide range of technical challenges efficiently and creatively. Some of these problems may lie outside your core areas of expertise, so technical curiosity and a self-starting attitude are critical for success.

We offer competitive salary, equity, 401k retirement savings, health, dental, and vision insurance, and paid time off.

In this role you will:

  • Heavily contribute to the mechanical design and validation of the the low-temperature plasma-based metrology sensor
  • Interface with a small, cross-functional project team to research, develop, and validate new concepts for low-temperature plasma-based metrology
  • Perform fundamental studies to characterize and understand the sensitivity of the sensor performance to various environmental factors
  • Closely interact with both small and large clients to iterate on the design based on their feedback, paying close attention to integration speed
  • Create and maintain technical design documentation (e.g., requirements, wiring diagrams, part schematics, and test reports)

You have:

  • B.S./M.S. in Mechanical Engineering with 5+ years industry experience
  • Experience autonomously leading independent mechanical design projects, in particular those that involve designing a product that can be integrated into a larger system.
  • Experience with hands-on development of prototypes
  • Experience with initiating and maintaining supplier support
  • Experience with maintaining awareness of customer needs and iterating on designs accordingly
  • Experience with mechanical design for manufacturing lines – experience with roll-to-roll and/or sheet-to-sheet processes is a huge plus
  • Familiarity with high-voltage devices
  • Experience with performing sensitivity analysis and using the results of those analyses to inform future mechanical designs e.g., quantifying a prototype’s sensitivity to certain environmental disturbances and creating a mechanical design that mitigates the effects of those disturbances
  • Prior exposure to high-precision, high-throughput industrial designs for material handling, metrology, and/or process automation applications are a plus.
  • Experience taking designs from initial concept development to product launch. Design for reliability, manufacturing, and service (DFx) are a plus.
  • Proficiency with use of CAD and PDM tools (e.g., Solidworks, Windchill) to design parts and assemblies and prepare technical documentation.
  • Ability to independently identify and procure parts, manage supplier relationships, and rapidly fabricate medium-fidelity prototypes using 3D printers, metal stock, optical breadboards, etc. is preferred.
  • Demonstrated the ability to adapt to new technical challenges and excited to work in a fast-paced, multi-disciplinary environment
  • Excellent written and verbal communication skills
  • Ability to rapidly create and iterate upon prototypes based on client and team feedback
  • (Preferred) Experience with metrology equipment and sensors, particularly those used for metrology of advanced materials
  • (Preferred) Some familiarity with thin films, in particular those related to Lithium- and Zinc-based battery electrodes, photovoltaics, optical coatings, displays, packaging materials, semiconducting wafers, and/or adhesives
