About Number 8 Bio Number 8 Bio is a venture-capital-backed start-up on a path to making a significant climate impact. We collaborate with farmers to enhance agricultural sustainability while boosting productivity. Our first products are innovative feed additives designed to eliminate methane emissions from the world's 2.6 billion cattle and sheep.
Methane, a greenhouse gas responsible for approximately ~30% of climate change, is more potent and shorter-lived than carbon dioxide. Eliminating man-made methane emissions is one of the fastest ways to combat climate change and ensure a sustainable future.
Based at Macquarie University in Sydney, we are a team of passionate innovators in climate science and technology. We offer a dynamic, intellectual environment, flexible work hours, and the opportunity to make a real difference.
About the roleWe’re looking for a hands-on, experienced Formulation Scientist with expertise in sustained-release systems, materials, or bolus/tablet technologies.
You will lead and support projects to deliver bolus products that perform consistently and predictably in vitro. This role sits at the intersection of formulation science, materials engineering, and product development - perfect for someone who loves building physical products, iterating quickly, and solving hard technical problems.
Responsibilities Partner with our Science & Engineering team to develop and improve our sustained-release bolus productsIdentify suitable materials and compositions; produce and test lab prototypes.Prepare lab and pilot-scale batches and support in-vivo tests to evaluate performance and suitability for scale-up.Analyse data and communicate insights to guide formulation decisions.Convert lab formulations into scalable production processes.Support early manufacturing runs, QC methods, and raw-material procurement.Prepare clear technical reports, documentation, and SOPs.Generate data to support regulatory submissions and patent filings.
Minimum Requirements A degree in Science (Applied/Industrial Chemistry, Materials Science, Pharmaceutical Science, Chemical Engineering or similar preferred) or strong, relevant industry experience.Minimum 5 years' experience in formulation and new product development (pharmaceutical, veterinary or similar sectors).Strong knowledge of chemistry principles, material behaviour in formulations (minerals, polymers, excipients).Experience with lab testing, data analysis, and structured communication and ability to work across disciplines.Physically capable of hands-on prototyping and mechanical/dissolution testing.
You’ll ideally have:Experience with sustained-release systems (bolus/tablets/capsules)Hands-on experience with dissolution, erosion, mechanical and stability testingExperience in regulated labs or manufacturing environmentsFamiliarity with APVMA requirements0 → 1 product development or scale-up experienceStrong problem-solving mindset and ability to iterate quicklyInterest in sustainability, agriculture, and climate technologiesWhy Join Us?Be part of a passionate team of innovators dedicated to combating climate change as we grow to commercial scaleEngage in meaningful work with significant global impactWe offer competitive remuneration and employee share optionsEnjoy a flexible and dynamic work environment within a great team
