Backend Engineer needed to join a small founding team at a pre-seed AI/fintech startup building AI-native operations infrastructure for private markets. You will own core backend systems that power fund accounting, reporting, reconciliation, and treasury automation, with a strong focus on permissions, auditability, traceability, and observability across both hosted and self-hosted deployments. This is a high-ownership, high-impact role for an engineer who thrives in early-stage environments and wants to shape foundational architecture from the ground up. Responsibilities include owning and managing backend infrastructure for permissions, auditability, traceability, and observability; designing deployment architectures for hosted and self-hosted environments using infrastructure-as-code tools; enhancing system reliability, performance, and security in production; partnering closely with product teams to ship features while maintaining high quality; and driving AI-native development practices to enable rapid, high-quality releases. Requirements: 1–6 years of backend engineering experience with a strong emphasis on permissions systems, auditability, traceability, and observability; hands-on experience with distributed systems and modern observability toolchains; comfortable working in a small founding team — strong ownership, initiative, and cross-functional coordination are essential; eligible to work in Germany and willing to work on-site in Berlin. Tech stack in use: TypeScript, NestJS, PostgreSQL, Prisma, Inngest, Mastra, React, Tailwind. Nice to have: background in fintec
