Why this role is remarkable
- Lead the most significant technical shift in Leapsome’s history, moving from reactive HR tools to a proactive, agent-driven platform that acts on deep employee context.
- Join a $60M Series A scale-up backed by Insight Partners with a profitable growth mindset and a mission-driven culture focused on making work fulfilling for everyone.
- Enjoy exceptional benefits including a top-of-market salary band, pre-IPO equity, a €2,000 annual learning budget, and the flexibility to work from anywhere two months a year.
What You Will Do
- Architect and build robust, scalable full-stack applications using Vue.js, Node.js, and MongoDB, integrating LLM-driven agents and stateful RAG pipelines for autonomous HR workflows.
- Partner directly with product and design as a strategic technical peer to shape the roadmap, challenge assumptions, and ensure engineering systems solve high-impact user problems.
- Pioneer engineering excellence by establishing AI evaluation suites, tool-calling schemas, and human-in-the-loop safety fallbacks while mentoring the broader team on AI-native development patterns.
The ideal candidate
- You have significant experience as a technical lead, founding engineer, or senior IC at a high-growth company with deep expertise in modern JS/TS frameworks.
- You possess a proven track record of shipping production-grade LLM applications, including multi-agent orchestration and advanced RAG architectures, rather than just basic prototypes.
- You are an AI-native developer who leverages tools like Cursor and CodeRabbit as force multipliers while maintaining total accountability for every line of code that ships.
