Purespring Therapeutics has hired process development scientists to turn kidney gene therapy methods into scalable AAV manufacturing. Anyone researching purespring therapeutics careers process development needs three answers. Whether roles exist. What the work involves. How to reach the hiring team.
What process development means in AAV gene therapy
Process development turns a method that works in a research lab into a manufacturing process that works every time at larger scale. For AAV gene therapy it has two main parts.
Upstream teams grow the cells that make the viral vector. US postings describe this work as cell culture and transfection through to harvest and lysis. Downstream teams purify the vector. Current US downstream roles involve designing and running development studies and writing technical content for regulatory filings such as an IND.
Both teams work alongside analytical scientists and quality staff. Their shared goal is a process that can transfer to a GMP manufacturing site without surprises.
What Purespring is building and why the stage matters
Purespring describes itself as a precision nephrology company that uses its GlomThera platform to deliver genetic therapies to podocytes in the kidney. Its lead program PS-002 targets IgA nephropathy. A second program PS-003 is moving toward the clinic in Alport Syndrome.
The stage of the company shapes the job. The Phase 1 and 2 study of PS-002 began enrolling patients in 2026. Study sites include US hospitals such as Johns Hopkins and the University of Miami. A company at this point needs process development staff who can support clinical supply while also preparing for later phase manufacturing.
| Fact | Detail |
|---|---|
| Headquarters | London United Kingdom |
| Focus | Gene therapy for kidney disease |
| Platform | GlomThera for podocyte delivery |
| Lead program | PS-002 for IgA nephropathy in Phase 1 and 2 |
| Second program | PS-003 for Alport Syndrome moving toward the clinic |
| Funding raised | About £115m ($150m) from investors including Syncona and Forbion |
| Manufacturing leadership | SVP Manufacturing Operations and Development |
The SVP Manufacturing Operations and Development is responsible for AAV vector manufacturing and critical starting materials supply as well as analytical methods from toxicology studies through late stage trials and commercialization. That tells you process development sits inside a function that covers the whole product lifecycle.
What earlier Purespring process development postings asked for
The company published job descriptions in 2022 and they show how it thinks about this function. They may not match any current opening so use them as a guide to expectations rather than a live listing.
The associate level role targeted a recent graduate with a life science or bioprocessing degree plus either a 12 month industrial placement or 1 to 2 years of industry experience. The senior role asked for 5 to 10 years of biotechnology process development experience and covered downstream AAV development under quality by design principles as well as tech transfer to external manufacturing partners.
| Level | Background asked for | Main focus |
|---|---|---|
| Associate Scientist or Scientist | Life science or bioprocessing degree with placement or 1 to 2 years in industry | Lab based process development and moving research processes toward clinical manufacturing |
| Senior Scientist or Scientist | 5 to 10 years in biotech process development ideally with GMP exposure | Downstream AAV optimization and tech transfer and vendor oversight |
The senior description also listed work that many candidates overlook. It included input to failure mode analysis and process characterization as well as monitoring vendor performance and securing supplies of critical starting materials. It even mentioned efforts to lower the cost of goods.
The posting stated plainly that many manufacturing activities are outsourced. This is the most useful detail for candidates. A process development scientist here spends time managing relationships with contract manufacturers and reviewing their data as well as running experiments.
Skills that matter most for this function
Based on the descriptions above and similar US postings these skills carry the most weight.
- Hands on AAV experience in either upstream or downstream work
- Chromatography and filtration knowledge for downstream roles
- Cell culture and transient transfection knowledge for upstream roles
- Experience writing process descriptions and protocols and technical reports
- Tech transfer experience with a CDMO or internal GMP site
- Familiarity with quality by design and risk assessment methods
- Basic understanding of CMC content in FDA and EMA filings
- Comfort with cost of goods thinking and supply chain basics
A comparable US role at a gene editing company expects candidates to design chromatography and filtration studies with a CDMO and to trend downstream process data. That overlap shows the skills transfer well between small AAV developers.
How to find and apply for a process development role
For purespring therapeutics careers process development seekers the main challenge is visibility. The 2022 postings pointed applicants to a careers page. That page now returns an error and the main website menu shows only About and Science and Patients and News and Contact. A dedicated listing page may return so check again before you apply.
Here is a practical approach.
- Check the company LinkedIn page and its jobs tab. The company has used LinkedIn to advertise process development roles before.
- Send a short and specific note to the contact address published on the website. The listed address is contact@purespringtx.com.
- Match your application to the work. Name the AAV unit operations you have run and the scale and the type of tech transfer you supported.
- Show evidence of working with external partners. This matters more here than at companies with large in house plants.
- Follow company news. Press releases signal new programs and these often come before hiring.
Keep your claims factual. Do not describe experience you cannot back up in an interview.
What US candidates should know about a London based employer
The company address is 188 York Way in London. I found no confirmed US office. This creates a few practical points.
- Work authorization: Confirm whether the company sponsors visas for the role before investing time in an application.
- Relocation: Ask about support for moving costs and timing.
- Pay: I found no published salary for Purespring process development roles. As a US reference point only a Novartis AAV downstream principal scientist role in San Diego listed a range of $108,500 to $201,500 for the first level. UK pay and benefits differ so do not assume equivalence.
- Regulatory exposure: US trial sites mean FDA familiarity is likely useful. This is my own reading and not a stated requirement.
Choosing between Purespring and a US AAV developer for your process development path
This choice depends on what you want to learn and how much risk you accept. Candidates exploring purespring therapeutics careers process development options should compare the two models honestly.
| Factor | Small outsourced model like Purespring | Larger US AAV developer |
|---|---|---|
| Breadth of work | Wide with vendor management and tech transfer and documentation | Often narrower with deep focus on one unit operation |
| Lab hands on time | Some lab work with heavy partner oversight | Usually more in house lab and pilot work |
| Company stage | Early clinical with funding tied to milestones | Varies from early stage to commercial |
| Location | London | Many US hubs such as Boston and San Diego |
| Career signal | Strong CMC and CDMO management profile | Strong technical depth profile |
Use this framework to decide.
- Choose a Purespring style role if you want exposure to CMC strategy and CDMO management and you are willing to relocate.
- Choose a US in house role if you want more bench time and wish to stay in the United States.
- Weigh funding and pipeline stage in either case. Early clinical companies carry more uncertainty than established ones.
- Ask any employer who runs manufacturing and where the process will be made. That answer tells you what your daily work will look like.
FAQs
Does Purespring hire process development scientists?
It has advertised process development roles in the past at both associate and senior levels. Current openings can change so check LinkedIn and the contact page.
