What is an R&D engineer?

An R&D (Research and Development) Engineering job involves designing, testing, and improving products, processes, or technologies. Engineers in this role work on innovation by researching new materials, methods, or techniques to enhance performance and efficiency. They collaborate with cross-functional teams, conduct experiments, analyze data, and develop prototypes. The goal is to bring cutting-edge solutions from concept to production while ensuring feasibility and compliance with industry standards.

Is R&D engineering a good career?

R&D engineering is a valuable career that involves developing new products and technologies, often requiring strong problem-solving skills and knowledge of engineering principles. It offers opportunities for innovation, collaboration, and continuous learning, with roles typically requiring a bachelor's or higher degree in engineering or related fields. Job stability and growth depend on industry demand and individual expertise.

What skills and qualifications are needed to thrive as an R&D engineer?

To thrive in R&D Engineering, you need a solid understanding of scientific principles, problem-solving abilities, and an engineering degree, often with specialization in a particular discipline like mechanical, electrical, or chemical engineering. Familiarity with CAD software, data analysis tools, prototyping equipment, and project management systems is typically expected, and certifications like Six Sigma or PMP can be advantageous. Strong collaboration, creativity, and effective communication skills help R&D engineers excel when tackling complex problems in multidisciplinary teams. These competencies are essential for driving innovation, ensuring technical feasibility, and efficiently bringing new products or processes from concept to reality.

What does an R&D engineer do?

A typical week in R&D Engineering involves a blend of hands-on experimentation, data analysis, team meetings, and documentation. You may spend part of your time designing experiments or prototypes, troubleshooting technical issues, collaborating with cross-functional teams (such as product development, manufacturing, or marketing), and presenting findings. In addition to technical tasks, you will likely participate in brainstorming sessions, literature reviews, and strategic planning. The pace can be dynamic and project timelines might shift based on new discoveries or business objectives, but the variety keeps the role engaging and intellectually stimulating.

Job description

MANUFACTURING ENGINEER
General Information
Position Title: Manufacturing Engineer
Department: Manufacturing
Reports to: Senior Manager, Manufacturing
Position Overview
The Manufacturing Engineer plays a critical role in supporting the manufacturing of Rani Capsules. This role involves providing technical assistance in the installation, preventative maintenance, and calibration of equipment, as well as ensuring process improvements and consistency in manufacturing operations. The position works closely with R amp;D engineering and quality teams to ensure device specifications align with device requirements.
Key Responsibilities
  • Actively support NPI by working hands-on on the production floor to troubleshoot issues, stabilize yields, and drive smooth transitions from development to full-scale manufacturing.
  • Collaborate with Development and R amp;D Engineers to execute effective design transfer, process characterization, and ramp plans.
  • Conduct process capability studies and apply DOE, SPC, and data-driven analysis to draw conclusions, implement improvements, and sustain gains.
  • Develop standard work, process controls, and monitoring methods to reduce variability across operators, materials, equipment, and workflows.
  • Investigate process deviations and failures; perform structured root cause analysis (5-Why, Fishbone, FMEA) and implement robust corrective and preventive actions (CAPA).
  • Proactively identify opportunities for improvement and challenge assumptions constructively to drive better outcomes.
  • Create and execute IQ/OQ/PQ and related verification and validation protocols, analyze results, and generate complete documentation and reports.
  • Ensure compliance with design control, validation, documentation, and change-control policies (FDA, ISO, cGMP, QMS).
  • Create and maintain clear, complete manufacturing documentation (MPIs, LHRs, WIs, forms, checklists) that reflect current practices and controls.
  • Train and guide technicians and assemblers; drive best practices and foster a culture of safety, quality, and continuous improvement.
  • Contribute to design-for-manufacturability (DFM), cost reduction, quality improvement, and automation initiatives.
  • Cultivate a mindset of ownership and innovation, where individuals actively seek out challenges and collaborate across teams to solve them
Experience
  • 3–7 years of hands-on experience in a manufacturing environment, with a proven track record in process development, optimization, and validation.
  • Extensive experience with process capability studies, FMEA, PPK, GR amp;R, SPC, and process development/validation.
  • Knowledge and experience with plastic injection molding as well as semi-automated and fully automated machines/processes
  • Proven ability to perform statistical data analysis and implement improvement plans using DOE and other methods.
  • Strong analytical and problem-solving skills including but not limited to DOE, and statistical data analysis
  • Knowledge of material science and polymer chemistry
  • Diverse background in process characterization and optimization in a manufacturing environment.
  • Experience with FDA regulations and ISO, cGMP, and QMS standards.
  • Experience with Statistical Software tools such as Minitab or JMP
  • Familiarity with cleaning and sterilization processes
  • Working knowledge of SolidWorks
Education
  • Bachelor’s Degree in Mechanical, Chemical, Manufacturing, or a related engineering field.
  • Relevant certifications as pertains to the position (e.g., Six Sigma, Lean Manufacturing, etc.) is a plus.
  • Proficiency in Microsoft Excel, Microsoft Word, and other engineering software tools.
  • Familiarity with metrology tools such as CMM, Micro-Vu, SEM, etc. is a plus.
Physical Demands
  • The employee is regularly required to stand, walk, and sit for extended periods during the performance of job duties.
  • Must be able to physically be present on-site to perform the required tasks.
