Fast, clean, traceable, and ready for customers, acceptance, insurance, and in case of disputes.
We are building a modern SaaS for the trades, with strong templates, clear workflows, and AI features that truly save time. We are looking for a Senior Software Engineer as a Tech Lead Full Stack who takes end to end technical ownership for backend and frontend and leads our four person engineering team. You set the technical direction, raise code quality and delivery to the next level, and help us build a product that moves the trades forward.
Key Facts for this Role
• Senior professional with multiple years of experience
• Experience leading a team in a technical role
• Hybrid setup: Onsite in our Cologne office and days home office
• Relocation bonus if you move to Cologne

• You take ownership of our architecture and codebase, assess it, and make decisions for scalability, stability, and clean long term development. You are the final decision maker for core technical topics.
• You establish quality standards and a reliable delivery routine. You lead our tech team (senior and junior engineers) and actively develop junior engineers.
• You are not a pure manager. You build critical features hands on in Laravel and ideally also in React, and solve complex problems pragmatically.
• You improve operations and performance: Redis for queues and caching, Docker setup, CI CD, and observability to keep releases stable and incidents under control.
• You integrate and evolve AI features, including robust workflows, prompt and output logic, monitoring, cost control, and guardrails.
• You support expansion towards mobile apps or clients and build a solid API foundation with auth, sync, and offline concepts.
• You work closely with our Product Manager, translate requirements into technical concepts, and balance scope, effort, and quality.
• You work directly with the founder, challenge decisions constructively, and build a technical roadmap that enables growth.
