Software Engineer Full-Stack (m / w / x)

AI that makes complex B2B sales simple.

With FoxBase’s AI Sales Advisor platform, companies can set up their own AI Product Expert, built for the real world of enterprise and “Mittelstand” companies.

We help companies turn complex product portfolios and consultation-heavy sales into fully digital, AI-powered experiences without compromising on quality, compliance, or control.

Our platform combines retrieval-augmented generation (RAG) with proven selection, configuration, and calculation technology to deliver precise, explainable, and compliant answers, across websites, chatbots, and digital channels.

Unlike most AI tools built for big tech budgets, FoxBase empowers every company to deploy high-impact, trustworthy AI that meets GDPR and ISO 27001 standards from day one.

We make cutting-edge AI accessible, secure, and enterprise-ready - strengthening the competitiveness of Germany and Europe in the new AI era.

Who we are

Founded in Düsseldorf, we’ve grown into a fast-moving team of engineers, product minds, and builders driven by curiosity and precision.

We value speed, ownership, and quality , but also team spirit, flexibility, and foresight, our five FoxBase core values that shape how we build, ship, and grow.

Our customers include some of Europe’s most innovative industrial and technology leaders. Together, we’re redefining what “AI-driven sales” means in highly regulated environments, combining enterprise-grade security with modern AI orchestration.

Tasks

Who are we looking for

We’re looking for a Software Engineer Full-Stack , who’s passionate about building production-grade AI systems. Someone who thrives on solving complex technical problems, thinks in systems, and ships solutions that are both elegant and efficient.

• Own medium-complexity areas end-to-end (API + database + UI touchpoints) with minimal guidance.
• Improve codebase health through pragmatic refactoring, standards, and thoughtful architecture evolution.
• Build with a strong product mindset : clarify the “why”, propose smart trade-offs, and iterate post-release based on outcomes.
• Deliver changes with appropriate tests (unit / integration) and reduce regressions through disciplined engineering practices.
• Strengthen reliability : debugging, incident hygiene, and improving observability (logging / metrics / alerts).
• Collaborate with Product, Customer Success, and Sales to translate real-world business complexity into scalable, maintainable solutions.
• Contribute to a team culture of transparency, low ego / high standards, and proactive unblocking.
