Role overview
B2B Saas, Social Care2–10+ employees
Elyndra builds software to reduce administrative burden in social care, starting with children’s care.
Social care is a £96bn sector under severe pressure. Fragmented tools and manual processes slow decision-making and increase the risk of unsuitable placements for vulnerable children. Elyndra helps care teams move faster and more safely by automating unnecessary admin and accelerating decisions, while keeping professionals in control.
We are a VC-backed startup and have raised £1m in pre-seed funding. We are a small, talent-dense team including Y Combinator exited founders. Our founder, Marcus, brings deep sector insight through direct family experience in care settings.
What you will do
- Lead the end-to-end technical roadmap, making critical architecture decisions that balance rapid iteration with long-term system stability.
- Design and implement intuitive UIs and robust backend services that translate complex data into actionable insights for non-technical care workers.
- Integrate LLM services and AI features into the core product while maintaining high standards for security and sensitive data handling.
Who this is a fit for
- Full-stack expert proficient in Python and React, with a proven track record of building and scaling secure cloud-based applications.
- High-agency, product-first engineer who has previously thrived in early-stage startups or built sophisticated side products from scratch.
- Experienced in integrating LLMs and implementing security best practices (GDPR) for handling highly sensitive personal data within the healthcare or social care space.
Why this role is remarkable
- Rare opportunity to join as a founding hire with generous early-stage equity and direct influence on the company's technical DNA.
- Backed by leading VCs and a strategic PE partner owning 160+ care homes, providing a clear, validated route to massive scale.
- Mission-driven work where your code directly improves outcomes for vulnerable children by removing friction from critical decision-making processes.
