We’re hiring our first four people.
Halo AI is building an antibiotic susceptibility test for newborns with sepsis that gives a result in about 90 minutes. A laboratory prototype has been tested on 1,214 blood cultures in 6 NHS labs, and we have raised £750k to turn it into an instrument that hospital labs can use.
So far the company has been one person, Ellie Rose, working with academic collaborators, NHS labs and a contract manufacturer. The four roles below are our first hires. We will fill the two graduate roles first.
Ellie Rose
Founder and CEO
Ellie Rose developed the method behind Halo AI in the Okoro Laboratory at the Sir William Dunn School of Pathology, University of Oxford, where she filmed 96 bacterial isolates against 8 antibiotics, 768 combinations in all. She is first author of the study in six NHS laboratories and reads biology at Corpus Christi College, Oxford.
Open roles
All four roles are based in Oxford. The salary ranges are below, and every role comes with equity.

Founding Associate, Finance and Operations
- Salary
- £75,000–£85,000 plus equity
- Location
- Oxford, UK
- Experience
- Open to recent graduates
The role
You will look after Halo AI’s finances and operations, working directly with the founder. The job runs from the financial model to the contracts with our first NHS pilot labs. It is our first non-technical hire and reports to the CEO.
What you’ll do
- Build the financial model and keep it current, including the unit economics of the Halo Reader and the cartridge.
- Write the business cases that NHS trusts need before they can adopt Halo AI.
- Prepare the data room for the Series A.
- Handle reporting to our grant funders.
- Manage contracts with laboratories, suppliers and our contract manufacturer.
What we’re looking for
- A degree in economics, business, finance or a STEM subject from a top-ranked university.
- Relevant experience in finance, consulting or a startup.
- You can build a three-statement financial model without help.
- You write clearly and can defend your numbers in front of an NHS finance director or an investor.
Founding ML Engineer
- Salary
- £85,000–£95,000 plus equity
- Location
- Oxford, UK
- Experience
- Open to recent graduates
The role
You will be responsible for the models that track each bacterium and decide whether an antibiotic is working, and for the pipeline that trains, tests and releases them. Halo AI will be a regulated diagnostic, so every model version goes out under change control.
What you’ll do
- Build and maintain the training pipeline for the cell-tracking and classification models.
- Put together frozen test sets and validate every model version against them.
- Take each model version through a change-controlled release.
- Work with the microfluidics and quality leads while the Halo Reader is being built.
What we’re looking for
- A degree in computer science, engineering, physics or maths from a top-ranked university.
- You have trained and shipped at least one vision model end to end, ideally on messy real-world images.
- You write tested, documented code that would hold up in a regulator’s audit.
Senior Microfluidics Engineer
- Salary
- £100,000–£110,000 plus equity
- Location
- Oxford, UK
- Experience
- 5+ years in device manufacturing
The role
You will take the cartridge from prototype lots to volume manufacture with our contract moulder. A cartridge that arrives at a hospital lab has to perform the same as the ones used in the study.
What you’ll do
- Lead cartridge scale-up with our contract microfluidics moulder.
- Qualify a second moulder.
- Set up lot release and run it.
What we’re looking for
- Five or more years in device manufacturing.
- You have taken an injection-moulded microfluidic or diagnostic consumable from prototype to production.
- You have worked hands-on with contract manufacturers, process qualification and lot release.
Head of Quality and Regulatory
- Salary
- £110,000–£120,000 plus equity
- Location
- Oxford, UK
- Experience
- 8+ years in diagnostics
The role
You will build Halo AI’s quality system from the start and take the company through UKCA marking as an in vitro diagnostic. No result will be used in patient care until that is done.
What you’ll do
- Build and run the ISO 13485 quality management system.
- Lead UKCA marking and the approved-body audits that come with it.
- Set up post-market surveillance before the first pilots.
What we’re looking for
- Eight or more years in diagnostics quality or regulatory affairs.
- You have taken an in vitro diagnostic through certification with an approved or notified body.
- You have built an ISO 13485 quality system from an early stage.
