England, United Kingdom Anson McCade Full time

Full-Stack Engineer – Remote (UK, Dublin, or Europe) Salary: Up to £80,000 + potential equity Our client is a fast-growing SaaS platform on a mission to help organisations measure and improve their people and culture initiatives. They’re a team of innovators, problem-solvers, and builders who believe in creating meaningful, measurable impact — combining AI-driven insights with scalable, user-focused design. They’re partnered with a start-up consultancy that embeds experienced engineering teams into early-stage companies, helping them scale from pre-seed through to Series A and beyond. This consultancy acts as the interim tech team for founders who are growing fast — so joining them means working directly on real-world problems that shape the future of early-stage products. The Role You’ll join as a Founding Engineer , working closely with the CEO and technical leads to rebuild and enhance the platform after the departure of the original founding engineer. It’s a broad, hands-on role that suits someone who thrives in a start-up environment — building end-to-end, making architecture decisions, and influencing long-term product direction. You’ll work across a modern full-stack environment — from frontend React and TypeScript to backend Node.js and AWS infrastructure — with the opportunity to introduce AI-driven capabilities using LLMs and agentic AI frameworks. Key Responsibilities Build, maintain, and optimise core features across the SaaS platform. Collaborate directly with founders and interim engineers to define product direction. Integrate AI-driven functionality (LLMs, agentic AI) to enhance user experience. Lead on architectural decisions and ensure scalability, reliability, and security. Contribute to DevOps, CI/CD, and infrastructure improvements across AWS/GCP. Tech Environment Frontend: React, TypeScript Backend: Node.js, Python Databases: PostgreSQL, MongoDB Cloud & Infra: AWS, GCP, Terraform, Kubernetes, Serverless CI/CD: GitHub Actions What They’re Looking For Strong experience in JavaScript/TypeScript and AWS (full-stack). Proven track record in building and maintaining SaaS products. High autonomy — comfortable taking ownership in a fast-paced, early-stage setting. Confident working remotely with occasional travel to Dublin. (Bonus) Experience with AI/LLM integrations such as LangChain or aisdk. Why Apply This is a rare opportunity to join a growing start-up at a pivotal moment — with real ownership, autonomy, and a clear pathway to grow into a technical leadership role. You’ll help shape both the product and the engineering culture while working alongside a consultancy that regularly partners with emerging start-ups — giving you exposure to multiple scaling businesses and future opportunities to lead new builds. If you’re a hands-on engineer looking to make a genuine impact, this is the kind of role that puts you at the centre of innovation from day one.
