Senior Full Stack Engineer

Senior Full Stack Engineer Location: Remote (Must accommodate US East Coast working hours). Preference for candidates based in Brazil. About Us Partnerships are the future of go-to-market. They drive 30-50% of company revenue, yet most partner teams are stuck with spreadsheets, email chains, and outdated CRMs, tools never built for partnerships at scale. The result? Wasted time, lost deals, and inefficiencies that kill growth. EULER is the AI-native PRM for modern partnership teams, built to replace manual work, eliminate partner friction, and turn partner activity into repeatable revenue and measurable ROI. We are not iterating on legacy PRM software. We are redefining what the category even is, and the market is taking notice. We grew 600% YoY in 2025 and serve industry leaders, consistently winning against legacy solutions in competitive deals. We move fast, build intentionally, and lead the market on innovation and AI. If you're excited to solve big problems, work with smart teammates, and shape the future of partner tech, we'd be glad to meet you.
