Job Title: Founding Engineer Full Stack

Salary: Up to 100k Equity

Company Description: 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 UKs 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.

• 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.

Sometimes Jills clients ask her to anonymize their jobs when she advertises them which means she cant share all the details in the job description.
We appreciate this can make them look a bit suspect but there isnt much we can do about it.

Give Jack a spin! You could land this role. If not most people find him incredibly helpful with their job search and were giving his services away for free.
