How to Write a Biotechnology Job Ad That Attracts the Right People

Biotechnology is one of the UK’s most diverse and fast-moving sectors. From biopharma and diagnostics to industrial biotech, medtech and life sciences research, employers are competing for highly specialised talent with scarce, in-demand skills. Yet many biotechnology employers struggle with the same problem: job adverts that attract the wrong candidates. Roles are often flooded with unsuitable applications, while highly qualified scientists, engineers and regulatory professionals either do not apply or disengage early in the process. In most cases, the issue is not the talent pool — it is the job advert itself. Biotechnology professionals are trained to think critically, assess evidence and understand context. If a job ad is vague, inflated or poorly targeted, it signals a lack of clarity and credibility — and strong candidates simply move on. This guide explains how to write a biotechnology job ad that attracts the right people, improves applicant quality and positions your organisation as a serious, trustworthy employer in the life sciences sector.

Maths for Biotech Jobs: The Only Topics You Actually Need (& How to Learn Them)

Biotechnology is packed with data. Whether you are applying for roles in drug discovery, clinical research, bioprocessing, diagnostics, genomics or regulated manufacturing, you will meet numbers every day: assay readouts, QC trends, dose response curves, sequencing counts, clinical endpoints, stability profiles, validation reports & risk assessments. If you are a UK job seeker moving into biotech from another sector or you are a student in biology, biochemistry, biomedical science, pharmacy, chemistry, engineering or computer science, it is normal to worry you “do not have the maths”. What biotech roles do need is confidence with a small set of practical topics that show up again & again. This guide focuses on the only maths most biotech job adverts quietly assume: • Biostatistics basics for experiments, evidence & decision making • Probability for variability, uncertainty & risk • Linear algebra essentials for omics, PCA & modelling workflows • Calculus basics for kinetics, rates & dose response intuition • Simple optimisation for curve fitting, process set points & model tuning

Neurodiversity in Biotech Careers: Turning Different Thinking into a Superpower

Biotechnology is all about solving complex problems that affect real lives – from new medicines & vaccines to sustainable materials, diagnostics & gene therapies. To tackle those challenges, the sector needs people who think differently. That is exactly where neurodivergent talent comes in. If you have ADHD, autism, dyslexia or another form of neurodivergence, you might have been told that your brain is “too much”, “too distracted” or “too literal” for a lab or scientific career. In reality, many of the traits that come with ADHD, autism & dyslexia are perfectly suited to biotech work – from spotting subtle patterns in experimental data to creative thinking around new solutions. This guide is written for biotechnology job seekers in the UK. We will explore: What neurodiversity means in a biotech context How ADHD, autism & dyslexia strengths map onto specific biotech roles Practical workplace adjustments you can ask for under UK law How to talk about your neurodivergence in applications & interviews By the end, you will have a clearer idea of where you might thrive in biotech – & how to set up your working environment so your differences become genuine superpowers.
