Company Description
Extracellular is a mission-driven Bristol biotech startup accelerating the production of sustainable cell-based products like cultivated meat and bio-materials. By blending biology with digital innovation and biomanufacturing, they provide R&D and manufacturing services that help companies reach commercial scale ethically and efficiently.
Job Description
You will own the technical backbone for a cutting-edge biotech laboratory, managing an on-prem stack of Linux hosts, Docker services, and MQTT data collection. As the sole infrastructure specialist, you’ll ensure scientific data flows reliably from lab instruments to the cloud, hardening systems and building observability without a technical safety net.
Location
Bristol, UK
Why this role is remarkable
- True technical ownership: You are the sole infrastructure engineer with full autonomy over a modern on-prem stack and its future evolution.
- Direct scientific impact: Your work directly enables the development of sustainable alternatives to current production methods like cultivated meat and ethical cosmetics.
- No bureaucracy: Experience a high-trust environment with no on-call rotations, no complex change boards, and a direct line to the Head of R&D.
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.

We never post fake jobs

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
