Product Development Scientist (R&D)

You work in an R&D laboratory developing and improving products — formulating new recipes or compounds, running stability and safety tests, optimising existing products, and generating the technical documentation needed to support regulatory approval and manufacturing scale-up.

• Formulate new product prototypes in the R&D lab or development kitchen
• Design and execute bench-scale experiments and trial protocols
• Conduct physical, chemical, and sensory evaluations of prototype formulations
• Run stability, shelf-life, and consumer safety testing on new formulations
• Document all experiments, results, and formulation records in lab notebooks and LIMS
• Compare prototype to commercial benchmarks and consumer target specifications
• Collaborate with marketing to incorporate consumer feedback into reformulations
• Support manufacturing scale-up by adapting formulations for production equipment
• Prepare technical reports, product specifications, and regulatory submission documentation
• Monitor raw material performance and investigate quality issues in existing products

R&D laboratory environment — food development kitchen, cosmetic formulation lab, or pharmaceutical development facility. Requires wearing PPE (lab coat, gloves, safety glasses). In Sri Lanka, found primarily at FMCG, food manufacturing, and pharmaceutical companies in and around Colombo.

Typical hours: 45h/week · WLB score 7/10 · OCCASIONAL overtime

Generally structured lab hours with occasional extended periods during product launch trials or consumer testing events. Physical lab work means the role is largely contained within working hours.

Typical progression: 3yr to mid · 8yr to senior

Freelance earnings: $15–$40/mo (USD)

Sri Lanka's growing craft food, beverage, and cosmetics sector creates opportunities for product development freelancers serving small brands that cannot afford in-house scientists.

Physical laboratory work, sensory evaluation, and creative formulation require hands-on expertise that automation cannot fully replicate. AI-assisted formulation tools exist but complement rather than replace scientists.

Students who love laboratory work, food science, or chemistry and want a career where their experiments directly create products that consumers use — those who enjoy the tactile satisfaction of making things.
