Research And Development Intern information

What is a research and development intern?

Research and Development (R&D) Interns are students or recent graduates who support a company's innovation and product development processes. They assist with experiments, data collection, analysis, and documentation under the supervision of senior researchers or engineers. R&D Interns gain practical experience by contributing to real-world projects, learning new techniques, and helping bring new products or improvements to market. Their work often involves collaboration with multiple teams and exposure to the research lifecycle within their industry.

What is the difference between Research And Development Intern vs Product Development Intern?

AspectResearch And Development InternProduct Development Intern
Primary FocusConducting research, experiments, and testing to innovate or improve productsDesigning, developing, and testing new products or features for market readiness
Work EnvironmentLaboratories, research centers, or R&D departmentsDesign studios, engineering labs, or product teams
Required SkillsAnalytical skills, scientific knowledge, data analysisDesign skills, technical knowledge, project management
Common Employer UsageTech companies, manufacturing firms, research institutionsConsumer electronics, software companies, manufacturing firms

Research And Development Interns focus on scientific research and testing to innovate, while Product Development Interns work on designing and bringing new products to market. Both roles support product lifecycle stages but differ in their core activities and environments.

What skills and qualifications are needed to be a research and development intern?

To thrive as a Research and Development Intern, you generally need a solid academic background in science or engineering, analytical thinking, and strong problem-solving abilities. Familiarity with laboratory equipment, data analysis software, and technical writing is often required, along with experience using tools like MATLAB, Python, or R. Initiative, curiosity, and effective communication skills distinguish top performers in this role. These skills are critical for contributing to innovative projects, supporting team goals, and effectively communicating findings within a fast-paced, research-driven environment.

What do research and development interns do?

As a Research and Development Intern, you can expect to be involved in a variety of hands-on projects, such as assisting with experiments, collecting and analyzing data, and supporting prototype development. Interns often collaborate closely with engineers, scientists, and other team members to brainstorm innovative solutions and improve existing products or processes. Typical responsibilities may also include conducting literature reviews, preparing technical reports, and presenting findings to the R&D team. This role provides valuable exposure to the full product development cycle and offers opportunities to build both technical and teamwork skills.

Job description

Battery R&D Internship

Enovix is seeking an R&D Intern to support the design, fabrication, testing, and analysis of lithium-ion batteries with silicon-based anodes. This role is well suited for a PhD student or graduate researcher with strong experience in electrochemistry, battery materials, cell testing, and failure analysis.

The ideal candidate will bring deep technical expertise in battery materials and electrochemistry, a hands-on approach to experimentation, and enthusiasm for addressing complex challenges in silicon anode commercialization.

The intern should be comfortable working across fundamental science, experimental execution, and product-focused battery development. The intern will collaborate closely with scientists, engineers, and technical leadership to support the development of high-performance lithium-ion cells.

Key Responsibilities

The intern will contribute to one or more of the following areas:

  • Design and evaluate silicon-based anode materials, composites, binders, conductive additives, and electrode formulations.
  • Fabricate electrodes and coin, pouch, or other test cells for electrochemical evaluation.
  • Perform battery testing, including formation, cycling, rate capability, fast-charge testing, impedance measurements, and diagnostics.
  • Analyze capacity retention, coulombic efficiency, impedance growth, swelling, and other key performance metrics.
  • Investigate silicon anode degradation mechanisms, including volume expansion, SEI evolution, particle fracture, lithium inventory loss, and electrode-level failure modes.
  • Use materials characterization techniques such as SEM, TEM, XRD, XPS, Raman, FTIR, BET, TGA, or related methods, as applicable.
  • Develop clear, data-driven recommendations to guide silicon anode material and cell design.
  • Document experimental procedures, results, and conclusions in technical reports and presentations.
  • Work cross-functionally with materials, cell engineering, process development, and product teams.
Required Qualifications
  • Currently enrolled in a PhD program at a leading university, national laboratory, or research institute with a strong focus on batteries, electrochemistry, materials science, chemical engineering, mechanical engineering, or a related field.
  • Research experience in lithium-ion batteries, preferably silicon-carbon or other advanced anode systems.
  • Strong understanding of lithium-ion battery fundamentals, including electrode design, interfacial chemistry, SEI formation, transport limitations, and cell degradation.
  • Hands-on experience with battery cell assembly and electrochemical testing.
  • Ability to analyze complex experimental data and translate results into actionable technical insights.
Preferred Qualifications
  • Direct experience with silicon anode materials, silicon-carbon composites, prelithiation, binder systems, electrolyte additives, or high-loading electrode design.
  • Familiarity with advanced diagnostic methods such as EIS, GITT, dQ/dV analysis, post-mortem analysis, gas analysis, or mechanical swelling measurements.
  • Experience using Python, MATLAB, JMP, Origin, or similar tools for data analysis.
  • Publications, patents, or conference presentations related to lithium-ion batteries or advanced anode materials.
  • Experience working in industry, a national laboratory, or a collaborative applied research environment.
What You Will Gain
  • Hands-on experience developing next-generation silicon anode lithium-ion battery technology.
  • Exposure to startup-style R&D, rapid experimentation, and practical cell development.
  • Opportunity to work closely with experienced battery scientists and engineers.
  • Experience translating academic research into commercially relevant battery technology.

This is a paid internship that will be onsite at our Fremont, CA office, with an expected duration of 3-6 months. The hourly pay range is $40–$45, depending on experience, qualifications, and other job-related factors.
