Parenting for Lifelong Health (PLH) is looking for a motivated and socially-committed legal professional to serve as the legal-focused trustee on PLH’s trustee board. 

About Parenting for Lifelong Health

Parenting for Lifelong Health (PLH) aims to empower parents to improve child development, reduce family violence, and promote mental health. We give parents the support they need, the skills that work, and trusted advice they can count on to protect and support their children’s health, safety and development.

Our parenting courses are developed with families, powered by low-cost and accessible technology, backed by rigorous evidence, and delivered within systems.

Data Preprocessing Model Specialist-Input Quality & Standardization

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
Your role will be to aid design and implement a preprocessing model that ensures all incoming cervical images meet strict quality and consistency standards before being passed into downstream models.
Our cervical cancer screening method is dependent on pictures taken using a smartphone, leading to large variation in lighting and cervix positions in the image. On top of natural variances in fluid blockages or rotation and angle or cervix, it’s important that only valid images are run through our model.

Key Responsibilities

• Build automated checks for:
• Lighting normalization
• Blur and focus detection
• Angle and framing validation
• Specular reflection handling
• Develop preprocessing models or heuristics to:
• Enhance image quality (contrast, de-noising)
• Standardize image format, resolution, and scale
• Implement image rejection and acceptance criteria pipeline
• Create a quality scoring system for input images
• Collaborate with CV and ML engineers to optimize preprocessing impact on performance
• Optimize preprocessing for real-world noisy data (mobile capture, low-resource settings)

Required Skills

• Strong background in computer vision fundamentals
• Experience with OpenCV, PIL, or similar image processing libraries
• Understanding of image quality metrics
• Experience building automated data validation pipelines

Preferred Qualifications

• Experience with medical image preprocessing

• Familiarity with variability across capture devices and environments

• 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

Minimum Hours per Week:

4-6 hours per week

Duration:

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
