📋 Description

• Build end-to-end solutions, selecting the ideal technology for each layer—from backend development and LLM integration to the final user interface, web pages, bots, or invisible automations. • Work closely with the People Operations team to map operational workflows. • Translate complex recruiting, retention, and leadership needs into efficient software products. • Actively participate in tool conception, focusing on reducing user friction, predefined success metrics, and delivering practical value. • Implement solutions compliant with Brazil’s LGPD, including data anonymization. • Structure evaluations (Evals) to monitor latency, model hallucinations, and the effective reduction of operational time.

🎯 Requirements

• Strong experience as a Full-Stack Developer, with the autonomy to work across frontend, backend, and data pipelines. • Experience using LLMs in products deployed to production. • Experience with microservices architectures, from design through implementation. • Product-oriented mindset: a natural inclination to understand user pain points before coding, balancing usability, technical feasibility, and design. • Excellent communication skills to align expectations and make trade-offs with non-technical stakeholders in People Operations, working effectively in ambiguous situations. • Previous experience building solutions, tools, or integrations for the HR ecosystem (HCM, ERP, etc.)—a plus. • Experience structuring tests and reliability metrics for AI models—a plus. • Productive use of development assistants such as Cursor, GitHub Copilot, or Claude Code—a plus.
