About the role

Mission: Integral was founded in 2024 to redefine how accounting, taxation and payroll work for SMEs in Europe, starting with Germany. The company is backed by General Catalyst, Cherry Ventures, Puzzle Ventures and entrepreneurs across Europe. As our Engineering Lead, you will help define our tech stack and shape our engineering culture. This role involves frequent context switching across multiple domains, technologies, and business problems. In a given week, you may move between infrastructure, backend systems, integrations, AI initiatives, frontend work, and discussions with product stakeholders. Success in this role requires comfort with ambiguity, strong prioritization skills, and a willingness to take ownership from problem definition through production deployment and ongoing support. You will work alongside experienced engineers in a small, high-impact team that takes pride in crafting quality solutions and learning together. This role is onsite at our Berlin office.
