Sr Mechanical Engineer

Overview

About Us

LiquidXR is an expanding, well-funded startup building a platform to digitize human movement. We are creating next-gen wearables using proprietary MetalGel sensor technology, capturing and feeding movement data to our machine learning-enhanced algorithms and SDKs, which connect to any modern computer or development environment. We are partnered with several high-quality companies co-developing products using our tech, and we are advancing our platform to enable all types of body movement data capture and analysis across multiple areas of use (gaming, sports, performance, XR, and more).

Our tight knit hardware and software team is comprised of experts in product and UX development, biomechanics, algorithms and machine learning, software platform and experience development, electronic engineering, and soft goods industrial design. Individually and collectively, this is a team who gets things done and among us, countless products have been launched worldwide. We are passionate about creating a transformative platform and we are fortunate to work on cool products using our tech along the way.

The Role

We are seeking a highly skilled and motivated Senior Mechanical Engineer to take ownership of critical design projects. In this role, you will be a driving force behind the physical architecture of our platform hardware technology and products, from initial concept to mass production. You will be responsible for designing, prototyping, refining, and validating deformable electronic interconnects and integrated systems, with a special focus on creating elegant and robust solutions for wearable devices. This is a hands‑on role for an engineer who loves to solve complex problems and build tangible, high‑quality products.

Responsibilities

• A minimum of 10 years of relevant mechanical engineering experience, with a strong portfolio of successfully launched products.
• Proven aptitude for developing innovative product solutions and leveraging novel technology to satisfy customer needs.
• Extensive experience with root‑cause failure analysis and technical problem‑solving for product design and manufacturing processes development.
• Experience with design verification and validation.
• Experience with 3D CAD software (e.g., SolidWorks, Inventor, Creo).
• Experience in designing for wearable technology, consumer electronics, or other miniaturized, high‑volume products is strongly preferred.
• Experience working with thermoplastic elastomers and familiarity with thin film extrusion, film lamination, and thermal bonding is a plus.

Who You Are

• An Owner : You possess a powerful ownership mindset and take full accountability for your projects from concept to completion.
• A Proactive Driver : You are a self‑starter who can "catch the vision and run with it." You thrive with autonomy and are skilled at moving projects forward with minimal oversight.
• A Team Player : You are a natural collaborator who communicates clearly and works effectively with cross‑functional teams to achieve shared goals.
• Adaptable and Resilient : You excel at managing multiple priorities without sacrificing quality. You see the challenges of a startup environment as opportunities.
• Detail‑Oriented : You have a keen eye for detail and are committed to producing high‑quality, well‑documented work.
