MednTech

We provide an Android AI tool that analyzes cervical images to support frontline screening decisions.

Synthetic Data Engineer-Medical Imaging

About MedNTech
MednTech is a nonprofit organization developing AI-powered tools to improve early detection of cervical cancer and expand access to care in underserved communities, particularly in Africa. It works by equipping frontline healthcare providers with accessible technology and partnering with local health systems to improve outcomes and empower patients. We have already implemented our diagnostic model in real-world settings in Rwanda. We are now looking to further improve its performance and robustness before our next deployment, and are currently seeking volunteers to support this initiative.

Why Volunteer With Us

We are early-stage, moving fast, and building something that matters. You will have real ownership over technical decisions that directly shape a tool going into the field. Cervical cancer is one of the most preventable cancers in the world, yet it remains a leading cause of cancer death in low-resource settings simply because screening does not reach the people who need it. The tool you help build changes that. If you want your code to save lives, this is that opportunity!

Role Overview
We are looking for a data professional to design and implement synthetic data generation pipelines. These images will be used to augment limited cervical image datasets and improve the robustness of our cervical cancer screening model.

Key Responsibilities

• Develop synthetic image pipelines using diffusion models (Stable Diffusion, DreamBooth, LoRA) or GAN-based approaches
• Generate class-balanced datasets, particularly for underrepresented abnormal cases
• Design and run experiments comparing real vs synthetic vs hybrid datasets
• Evaluate synthetic data quality using FID, KID, and downstream model performance
• Implement prompt engineering and conditioning strategies for medically realistic outputs
• Perform domain gap analysis between real and synthetic data
• Collaborate with ML engineers to integrate synthetic data into training pipelines

Required Skills

• Experience with PyTorch and Hugging Face Diffusers or GAN frameworks
• Strong understanding of data augmentation vs synthetic generation tradeoffs
• Experience evaluating generative models (FID, distribution alignment)
• Familiarity with medical imaging challenges (preferred but not required)

Preferred Qualifications

• Experience with GAN based models and LoRA fine-tuning pipelines

• Prior work with imbalanced or medical datasets

• Understanding of bias in synthetic data

• All roles are highly collaborative and will work closely across the MednTech AI pipeline

• Experience with healthcare AI, low-resource environments, or global health applications is a strong plus

• Candidates should be comfortable working in fast-paced, early-stage environments

Do you want to take part in vegan volunteering around your local area?

You can do that – right here at The Vegan Society. 

We have an ever-growing Community Network of vegans just like you, who have a passion to volunteer and promote veganism where they live. 

Every month, our Network choose from a range of outreach tasks. These could include town centre stalls, writing to a councillor or MP, sharing our campaigns on social media or contacting local businesses. You're in control of how much or how little you do. 

As an Advocate, you will have a network of other Advocates and an Organiser in your area. Your Organiser will be your main point of contact. They will send you tasks every month and ask you to feed back on what you've completed and any positive outcomes. 

Why do we need you to volunteer?

As the vegan community grows, veganism itself becomes better understood. We're finding that more people are looking to The Vegan Society to find out what being vegan is all about.

Local communities are starting to see the vegan movement as something real and something that’s happening in their area. More people are embracing a vegan lifestyle, which we welcome. From new businesses, to families, to councillors, many people need support. This could be with a range of topics: going vegan, finding correct information around a vegan diet, providing vegan options in their business, MPs listening to vegan constituents, and learning about our work.

Local issues are often unique and more varied than national issues. Our volunteers from local areas are vital! They enable us to share our messages and campaigns in an effective way. Research tells us that people are far more likely to trust information from a peer rather than an outside expert, so community volunteering vastly increases the impact of our campaigns.

Our network of committed local vegans across the country is growing! The Vegan Society organises various outreach activities to influence change in every level of society. There are a range of activities going on all the time, from general educational stalls at events to meeting with local policy influencers.

Advocates are a crucial voice in their own community. They ensure that our campaign messages are spread far and wide. They provide a strong vegan presence in local communities.

What does the Advocate role involve?

Being an Advocate for veganism with The Vegan Society will mean communicating with people in your local community. You'll share the benefits of a vegan lifestyle. You will form part of a local group, headed up by a local Organiser. The Organiser will feed back your collective efforts to staff. You will also be invited to our private Facebook group, for vegan socialising and ideas sharing.

You’ll stay in touch with the Organiser and bring your passion to tasks. Activities can range from staffing a stall to giving a talk at an employee event. It could also mean writing to a local newspaper or lobbying an MP.

Messaging can differ every month. Part of our mission statement is to ensure people can remain vegan, so you might focus on getting more vegan options available in local businesses. Or within our Live Vegan for Less campaign, you may share cheap vegan recipes to help people with the cost of living.

When acting as an Advocate, you will use The Vegan Society’s branding and messaging guidelines. Your local Organiser will guide you in doing this, as they hold physical resources and handbooks. You can report any issues and feedback you have to your Organiser. You can also contact staff if your Organiser isn't available or you have any problems.

What training and support is available?

You will be provided with a big welcome and full induction from your local Organiser. They will introduce you to the group and any actions that are ongoing. Any training and development will be provided via your Organiser, and you can also ask for specific training on any areas that you need some development in.

What skills would be useful in doing this role?

• The ability to stay motivated in order to achieve the best possible outcomes
• Good email etiquette, responding in a timely manner
• Committed to veganism and the mission of The Vegan Society
• Ability to stay calm if confronted with differing opinions or challenges
• A good communicator, with the ability to be persuasive
• Confident in communicating with people from a range of backgrounds
• Experience of campaigning
• Any experience in talking with members of the public through customer/public service would be helpful
• Awareness of current affairs, especially those that relate to veganism
• Regular availability and a willingness to stay committed to actions
• Good team player

How much time do I need to invest? 

For Advocates, we ask for people to engage in a minimum of four to six actions per year. An example of an action could be writing to an MP or holding a stall. But the more you can do, the better! On occasion, there may also be online meetings to plan for actions or provide training.

What will you be doing?

As our Technical VR Advisor you'll act as a senior technical voice for the team, providing strategic technical guidance and sharing your experience rather than day-to-day management. Working alongside our Lead Developer and a motivated team of four software developers, you will have the opportunity to:

This role has two sides, and you might lean more towards one than the other:

Product and strategy guidance:

• Advise on hardware decisions, particularly our upcoming transition to standalone VR headsets
• Share knowledge of the VR landscape: tools, platforms, what's working in the industry to help us make smart choices with limited resources
• Help us think about user experience design for an educational audience aged 14–18

Technical and development guidance:

• Advise on software architecture, tooling, and development practices for our Unity/C# VR application
• Mentor volunteer developers, helping them think through technical problems and grow their skills
• Guide the team on performance optimisation and best practices
• Help flag technical risks or opportunities as our product evolves

Note: Strength in either area is valuable (both together is ideal). This is a flexible advisory role and you can shape your involvement around where your experience has the most impact.

What are we looking for?

• Solid knowledge of the VR/XR space
• Familiarity with the VR hardware landscape, particularly standalone headsets (e.g. Meta Quest)
• We'd ideally love someone with professional or substantial hands-on experience in VR, but if you've built that depth through research, teaching, or personal projects, we'd still love to hear from you
• Experience with Unity and/or C# is a bonus but not essential - product and strategic experience in VR is equally valuable
• An interest in mentoring or teaching
• Someone who can commit roughly 1–3 hours per week, with the flexibility to scale up occasionally
• Passion for education, equity in STEM, or making technology accessible to young people

Nice to have: experience with educational software, interactive design, or working with non-profit / volunteer teams.

What difference will you make?

By lending your experience you'll be directly contributing to our goals to:

• Educate students aged 14–18 on the real-world applications of physics using VR
• Increase equitable access to super-curricular STEM activities in disadvantaged communities
• Show young people that physics can lead to exciting careers beyond academia

This role is important in order to have a smooth running chapter, so that the magic of our visits are at their full potential! We are searching for a enthusiastic and hard working volunteer to support the President in Newcastle!
