Description
Company
Bactobio is a London-based biotechnology company. We use breakthrough technologies in synthetic biology, next-generation sequencing, and machine learning to cultivate the 99% previously unculturable microbes. These microbes constitute the biggest bioresource in life, and our exclusive access allows us to discover novel chemicals that can be applied across a variety of markets.
We are impact-driven. Our first goal is to solve the growing antimicrobial resistance crisis through novel antibiotics and stabilise global food security through novel natural biodegradable fungicides.
We prioritize in-office work for fostering collaboration, with most of our computational team in our Vauxhall office 4 days a week. We're flexible when it matters, but this role is not suitable for someone seeking a fully remote position.
Role & Team:
Software is critical to our scientific endeavours. You’ll join the growing software team that builds and enhances the application and infrastructure used by our scientists to accelerate their search for novel compounds.
The application gives the lab scientists a holistic view of the scientific pipeline, ensuring that data is captured, processed, and visualized in a way that optimises the flow of scientific samples from team to team.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
