Materials Technician at Carbon, Inc. — Sunnyvale, CA

We're looking for a curious, hands-on Materials Lab Technician to join Carbon's Materials team. This is an entry-level role built for someone who wants to learn the fundamentals of polymer formulation and materials testing in a fast-moving additive manufacturing environment. You'll work closely with our scientists day-to-day, helping move formulation projects forward while keeping our lab running smoothly and safely.

This role is onsite 5 days per week at our Sunnyvale, CA location.  This role is not eligible for relocation, nor eligible for current Visa sponsorship.

What You'll Do

• Formulation Support: Assist scientists with the preparation, weighing, and mixing of resin formulations following strict written protocols.
• Sample Preparation: Prepare samples for testing, which includes 3D printing, post-processing, and standard specimen preparation.
• Testing & Analysis: Set up, run, and record results from routine materials tests (including mechanical, thermal, and rheological testing).
• Documentation: Maintain accurate, up-to-date lab notebooks and digital data records.
• Inventory & Lab Ops: Monitor and organize lab consumables and reagents; proactively flag restocking needs and help maintain a clean, safe, and organized workspace.
• Equipment Care: Clean, calibrate, and perform basic troubleshooting and maintenance on lab equipment.
• Safety Compliance: Strict adherence to all lab safety procedures, chemical handling guidelines, and hazardous waste disposal protocols.
• Hazardous Waste: Ensure all wastes are properly labeled with waste type, date of accumulation and any mandatory hazardous signals.

What We're Looking For

• High school diploma or equivalent; coursework or an Associate’s/Bachelor’s degree in chemistry, materials science, or a related field is a plus, but not required.
• Strong attention to detail and the ability to follow technical written protocols precisely.
• Excellent organizational habits and reliable, structured record-keeping.
• Comfortable working hands-on with chemicals and laboratory equipment.
• A collaborative attitude and an eagerness to learn from scientists and senior team members.
• Ability to work onsite 5 days a week in a lab environment.
• Physical ability to stand for extended periods, wear required Personal Protective Equipment (PPE), and safely lift/move lab materials (up to 30 lbs).

Nice to Have

• Any prior lab experience, whether formal or informal (school chemistry labs, maker spaces, or hands-on hobby projects).
• Familiarity with basic lab safety practices (GHS labeling, Safety Data Sheets [SDS], and PPE).
• Prior exposure to or hobbyist experience with 3D printing.

At Carbon, we look at the person holistically and carefully consider a wide range of factors when determining salary. The compensation bracket for this position is $28.99 - $37.64 (per hour). In order to maintain equitable internal pay practices, we aim to hire new employees near the midpoint of $33.32 per hour taking into account your experience, work location, certifications, and the unique skills you bring to the role.
