Key Responsibilities
Design and implement enzymatic reaction cascades combining hydrogen, hydrogenases and biocatalysts for selective small-molecule reductions and oxidations.
Apply synthetic organic chemistry principles to evaluate substrate scope, product formation, reaction selectivity and downstream processing.
Develop and optimise biocatalytic reactions from small-scale screening through to preparative and larger-scale experiments.
Investigate reaction parameters including substrate and enzyme concentration, pH, temperature, solvent composition, oxygen transfer, hydrogen delivery and cofactor balance.
Use automation, miniaturisation and data-driven workflows to increase the efficiency and quality of reaction screening and process optimisation.
Characterise substrates, intermediates and products using appropriate analytical techniques, including LC-MS, GC-MS and NMR.
Assess reaction performance using metrics such as conversion, selectivity, productivity, catalyst loading and process mass intensity.
Contribute to the development of scalable, safe and sustainable approaches for biocatalytic chemistry.
Collaborate with AZ scientists, academic partners and external technology providers.
Prepare manuscripts for publication in high-quality scientific journals and present findings at internal and external conferences.
Contribute to the supervision and mentoring of PhD students, graduate scientists and master’s students, where appropriate.
Essential Requirements
A PhD, or equivalent, in biocatalysis, synthetic organic chemistry, enzyme engineering, chemical biology, process chemistry or a related discipline.

Why Apply?
This is an opportunity to conduct cutting-edge research at the interface of biocatalysis, synthetic chemistry and process development. You will work with experienced scientists in a collaborative environment and have access to advanced facilities, analytical capabilities, automation and technical expertise.
Your research will focus not only on demonstrating new chemistry, but also on understanding how biocatalytic processes can be optimised, scaled and applied in an industrial context. The methods and technologies developed during the project may contribute to future sustainable manufacturing approaches within AZ.
The role will also provide opportunities to develop your publication record, present your work internationally, build collaborations across academia and industry, and strengthen your career in biocatalysis, synthetic chemistry or process development.
Why AstraZeneca
The position offers the opportunity to conduct research within a pharmaceutical company while retaining strong links to academic and external industrial partners. You will benefit from access to AZ’s scientific expertise, equipment, datasets and multidisciplinary networks, including resources that may not be available in an academic environment.

How we calculate "similar"
No black box, no LLM guesswork: a deterministic score built from four normalized attributes. Here's this role's own peer group at different match levels, so you can see the mechanism, not just the result.
Every comparison starts from the same 100-point budget: 25 for working in the same function, 40 for the same therapeutic area, 20 for the same or adjacent seniority, 15 for the same country. A dimension we can't confirm on both sides contributes nothing, never a guess, never a free pass.
0 points, never a partial guess. A role we know almost nothing about beyond its function bottoms out at 25%; it never inflates to 100% just because there's little to compare against. Seniority uses a defined ladder (Associate → Manager → Associate Director → Senior → Principal → Director → Senior Director → Executive/VP) so "Director" and "Senior Director" count as adjacent, but "Director" and "Executive/VP" do not.
