Careers
Baxtra is a medical research company working on investigational countermeasures for high-consequence pathogens and surgical technology. The work is difficult, slow and mostly invisible outside the organisation. We hire people who want to do careful work when the outcome is uncertain, the controls are real and the useful answer may be that a programme should stop.
412 people work here, including 268 in research and development. This page describes the work and the current openings as at 31 August 2026. All roles are subject to the same disclosure, biosafety and quality obligations as the programmes they support.
Why it is difficult, and who it suits
High-consequence pathogen research has no reliable shortcut. The scientific question may be narrow, the samples may be scarce, and the experiment may take months to arrange before anyone can learn from it. A result that rules out a mechanism is still useful, but it does not make a good headline. Much of the work is documentation, validation, cleaning, training and waiting for an independent check. In our surgical technology business, the same pattern appears in a different form: a device must be understood in use, not merely made to look convincing on a bench.
The people who tend to do well here can stay precise when a plan changes. They ask what the evidence supports, not what a meeting would prefer to hear. They can work inside a procedure without treating the procedure as a substitute for judgement. They explain uncertainty clearly, accept review from colleagues outside their discipline and record an uncomfortable observation before it becomes a larger one. Curiosity matters, but so do restraint, repetition and the willingness to stop when a control is missing.
This is a poor fit if you need a short path from idea to recognition, dislike regulated records, or regard safety and quality work as an interruption to the real job. It is also a poor fit if you expect every programme to become a product. Some will not. The organisation is built to learn from that outcome rather than conceal it.
What Baxtra is actually like to work at
Long timelines are normal
From a sound hypothesis to a decision that can survive quality review, the interval is usually measured in months and sometimes longer. Scheduling, assay development, material qualification, containment access and document review all take time. A quiet week does not mean the work has been forgotten. It often means someone is checking whether the next step is justified.
Most programmes fail
Our pipeline contains investigational programmes, not promises. Most research programmes, including sensible ones, do not reach their intended endpoint. A programme may be stopped because the biology is unconvincing, the route cannot be manufactured, the safety margin is not adequate, or the evidence cannot support the proposed regulatory route. Stopping is not treated as a personal failure, but it can still be a hard meeting to attend.
Containment work is physical
The Palm Coast maximum-containment BSL-4 suit laboratory was commissioned in July 2026. Entry uses a positive-pressure suit, a two-person rule and universal stop-work authority. A single entry has a four-hour maximum. The suit is hot, movement is constrained and ordinary tasks take longer. People leave tired. This is not a room in which you improvise because the planned method is inconvenient.
The work is not glamorous
There are no cinematic breakthroughs on a dependable schedule. There are shift handovers, inventory checks, waste routes, deviation investigations, version-controlled methods, repeated training and equipment that needs servicing. There are also long stretches when the most responsible contribution is to make a negative result legible to the next person. We would rather say this before an interview than ask a new colleague to discover it in month two.
We do not offer a relaxed route around regulation, an environment where every idea is funded, or a guarantee that a role will remain attached to the same programme for its whole term. We do not offer a promise of publication for work that cannot be disclosed, or a title that is more senior than the responsibilities it carries. We do offer direct access to the people making decisions, clear stop-work authority and the expectation that a well-supported concern will be recorded rather than managed out of sight.
The hiring process, step by step
We try to make the sequence predictable. Timings are working-day estimates, not commitments; biosafety, quality and regulatory roles can take longer because the relevant reviewers are not all in the same team. You will be told if the sequence changes.
| Step | What happens | Expected timing |
|---|---|---|
| 1. Application review | A hiring manager and a member of the relevant function review your CV, cover note and answers to the role questions. We look for evidence of the required work, not a particular employer or a polished career story. | 5 to 10 working days |
| 2. Short conversation | A 30-minute video call covers the role, location, working pattern, salary range where applicable and any eligibility or access constraints. This is also the point to ask whether the actual work suits you. | Within 10 working days of review |
| 3. Technical discussion | You meet two colleagues for a structured discussion of methods, decisions and a past piece of work. Containment candidates discuss practical constraints; clinical and quality candidates discuss inspection-ready records and escalation. | 1 to 2 weeks after step 2 |
| 4. Work sample | Most roles include a paid, time-boxed exercise such as reviewing a short data set, writing a risk note or planning a study hand-off. It is not free consulting and is not used to test whether you will work unpaid overtime. | 3 to 5 days to complete |
| 5. Panel and references | A cross-functional panel considers the evidence against the job criteria. Finalists are asked for two professional references, with permission, and receive a written summary of the remaining steps. | 1 week |
| 6. Offer and checks | The offer sets out reporting line, location, working pattern and conditions. Identity, employment and role-appropriate regulatory or biosafety checks are completed before a start date is confirmed. | 1 to 3 weeks |
A rejection is not a judgement on your value. It usually means another person gave clearer evidence for this particular role at this particular time. We aim to close the loop rather than leave candidates to infer an answer from silence.
Benefits and boundaries
Benefits vary by location and employment status, and the written offer is the controlling document. The outline below is intended to make the conversation less one-sided.
Health and leave
US employees receive medical, dental and vision cover options, an employer contribution to a retirement plan, paid annual leave, paid sick leave and recognised public holidays. Parental and family leave is available under the company policy, with the exact terms explained before acceptance.
Learning and review
Role-specific training, required biosafety and quality training, and a learning budget are provided within team plans. Performance is reviewed twice a year, with a written record of expectations. A training need is not treated as a character flaw.
How work is arranged
Remote work is available only where the role can be performed without weakening controls. Lab, facilities and many clinical operations roles are site-based. Flexible hours can be discussed, but a four-hour containment entry limit is a safety control, not a flexible scheduling option.
Equipment and access
Site-based roles receive the protective equipment and onboarding required for their work. Access is granted by role and training, not by enthusiasm. Everyone can raise a safety, quality or disclosure concern without first securing permission from the person whose work is questioned.
What we do not promise
We do not promise remote work for every role, rapid promotion, a private office, uninterrupted funding, or that a programme will continue. We do not pay for heroics that create a control problem. Overtime and on-call expectations are discussed by team before an offer is made.
A candid trade-off
The benefits are useful, not a substitute for good management or safe working conditions. If a benefit matters to your decision, ask for the policy and read it. If the answer is not known, we will say that it is not known rather than invent a reassuring version.
Fourteen roles across three working locations
These are the current openings. Palm Coast roles support containment, laboratory and site operations. Cambridge roles are concentrated around discovery, clinical and regulatory work. Remote (US) roles still require reliable overlap with the teams and travel when the work requires it. A role may close before this page is revised.

How to apply
Use the role-specific application link when one is provided in the vacancy record. Submit a CV, a short note explaining the relevant work and, where requested, answers to the role questions. Do not send patient-identifiable information, unpublished pathogen sequence data or confidential material from a previous employer. We do not need a long personal statement.
Tell us if you need an adjustment at any stage of the process. A request can be as simple as asking for a written agenda, a different interview format or more time for a work sample. It is handled by the recruiting contact and does not go to the panel as a test of character.
Speculative applications are read, but they are rarely answered individually. If there is no suitable opening, we generally retain only the information permitted by our privacy notice and do not create a role to accommodate a strong general profile. Please do not write to the Disclosure Review Board, the biosafety team or a laboratory address to ask for a job; those routes cannot process applications.
Questions about a listed role can be sent through its application route. If a posting does not say who to contact, write to careers@baxtra.pages.dev with the role title in the subject. We aim to acknowledge a question within five working days. Please do not include health information, passport details or other sensitive personal data in an initial email.
Read the work, then decide if it is for you
Our public science, biocontainment and responsibility pages describe the constraints that sit behind the vacancies. They are not recruitment copy, and they will not make the work sound easier than it is. That is deliberate.
