Elyndra – VC-backed social care startup with YC-exited founders

Job Description

As the Founding Engineer at Elyndra, you will lead the technical development of an AI-first platform designed to fix the UK’s broken £96bn social care sector. Working directly with YC-exited founders, you will architect and build software that automates administrative burdens, ensuring vulnerable children find stable placements faster and more reliably.

Location

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.

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.

The ideal candidate

• 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.
