Lead Full Stack Engineer (Berlin)

GeneralMind; Berlin; Hybrid; EUR 90.000 - 150.000; Vollzeit

Zusammenfassung

GeneralMind is seeking a Lead Full Stack Engineer to own the core architecture across frontend and backend, setting the technical bar and guiding the team. You will work with the founders on systems that orchestrate real operational workflows and AI infrastructure.

You will design production-grade applications with Python (FastAPI) and React (Next.js), build durable backend workflow systems with Temporal, and ensure reliability, observability, and scalable multi-tenant platforms across ERP

Qualifikationen

• Strong ownership mentality and systems thinking; care about UI state and backend queries.
• Deep experience with React and modern frontend ecosystems.
• Deep experience with Python and distributed backend systems.

Aufgaben

• Design, build, and evolve production-grade full-stack applications using Python (FastAPI) and React (Next.js).
• Architect and develop next-generation interfaces for our Systems of Action, enabling seamless human-in-the-loop interactions and complex data visualization.
• Build durable backend workflow systems using Temporal to support asynchronous AI agent execution.
• Improve reliability, observability, and operational tooling across both client and server applications.
• Integrate with enterprise systems such as ERP platforms (SAP, Dynamics) and external APIs, surfacing that data intuitively on the frontend.
• Scale multi-tenant systems, database architectures (PostgreSQL), and platform abstractions.
• Work closely with product and forward-deployed engineering teams to translate real customer problems into cohesive end-to-end features.

Jobbeschreibung

GeneralMind builds AI Systems of Action for complex enterprise workflows. We deploy AI employees that automate messy operational handovers across supply chains - processing orders, validating invoices, coordinating suppliers, and handling exceptions directly on top of enterprise systems like SAP, Oracle, JDE, and Dynamics.

Our platform combines AI agents, operational context graphs, and real transaction data to achieve Autopilot-grade automation in real operational environments. We work closely with leading global companies across manufacturing, retail, and logistics to deploy AI into mission-critical workflows.

About the role

We are looking for a Lead Full Stack Engineer to own and evolve the core architecture of the company across both the frontend and backend, and to set the technical bar for how the rest of the engineering team builds full-stack features.

You will work directly with the founders on systems that orchestrate real operational workflows across emails, documents, humans, databases, and ERP systems. A crucial part of this role is bridging our AI infrastructure with user experience - you will build the next-generation interfaces where human operators collaborate with our Systems of Action, and make the architectural calls that other engineers will build on top of. The work sits at the intersection of full-stack engineering, workflow orchestration, UI/UX architecture, and AI infrastructure.

This is not a feature-factory role. We want someone who can hold large parts of the system in their head, make strong architectural decisions across the stack, and raise the quality bar for the team.

What you will do

Design, build, and evolve production-grade full-stack applications using Python (FastAPI) and React (Next.js).

Architect and develop next-generation interfaces for our Systems of Action, enabling seamless human-in-the-loop interactions and complex data visualization.

Build durable backend workflow systems using tools like Temporal to support asynchronous AI agent execution.

Improve reliability, observability, and operational tooling across both client and server applications.

Integrate with enterprise systems such as ERP platforms (SAP, Dynamics, etc.) and external APIs, surfacing that data intuitively on the frontend.

Scale multi-tenant systems, database architectures (PostgreSQL), and platform abstractions.

Work closely with product and forward-deployed engineering teams to translate real customer problems into cohesive end-to-end features.

What we are looking for

Strong full-stack engineering fundamentals and production experience owning end-to-end feature delivery.

Deep experience with React and modern frontend ecosystems, coupled with a strong eye for user experience and interface design.

Deep experience with Python and distributed / backend systems.

A strong ownership mentality and systems thinking - you care just as much about UI state management as you do about backend database query optimization.

Ability to design reliable, observable, maintainable systems.

Comfort operating in ambiguous, fast-moving startup environments.

Clear communication and sound engineering judgment.

Excitement about AI-native software development and agentic systems.
