AI Software Developer

Role Overview

• You will join our AI & Automation team, with a dedicated product manager and a tech lead, build, and ship AI-powered features that fundamentally change how accounting works
• The goal is exception-driven accounting
• where AI handles the majority of transactions automatically, and humans focus on review, control, and complex cases
• You will build production systems that process real financial data for real businesses, with high standards for correctness, auditability, and transparency
• Agentic workflows and automation
• Build intelligent automation that suggests, matches, and processes accounting transactions
• Design confidence scoring, decision thresholds, and human-in-the-loop approval flows that determine when automation can proceed safely and when human review is needed
• AI runtime services
• Develop and maintain the AI services (Python / TypeScript) that power classification, matching, and suggestion logic
• Evaluate and integrate LLMs for specific accounting use cases, including RAG pipelines and tool-calling architectures
• Assistant experience
• Contribute to BHB's AI assistant that helps users with accounting queries, task execution, and contextual guidance within the platform
• Learning loops and metrics
• Build feedback mechanisms so the system continuously improves
• Track automation rates, suggestion acceptance, and error patterns. Turn user corrections into training signals
• Data foundation for AI
• Work with structured transaction and line-item data to ensure high-quality inputs for all AI features
• Help build the semantic context engine that gives agents the right context for decisions

Requirements

• Between 3 and 5 years of professional experience in software development with a strong focus on AI-powered product features
• Hands-on experience building production AI systems
• not just notebooks and prototypes, but services that run reliably, handle edge cases, and are observable in production
• Proficiency (having at least 3 years of hands-on experience) with Python and/or Typescript and familiarity with modern AI/ML tooling (LLMs, RAG, embeddings, vector stores, prompt engineering)
• Understanding of agentic architectures
• tool-calling, orchestration patterns, confidence-based routing, and human-in-the-loop design
• Strong software engineering fundamentals and experience
• clean code, API design, testing, CI/CD, microservices and the discipline to ship safely in a domain where correctness matters
• Comfort with ambiguity and ownership
• this is a growing team. You'll shape how AI works at BHB, not just execute tickets. You should be proactive by figuring out the right approach, not just implementing a spec
• Nice to have: Experience in fintech, accounting, or compliance-heavy domains
• Familiarity with German accounting concepts (SKR03/SKR04, GoBD, DATEV)
• Experience with MCP (Model Context Protocol) or similar tool-integration patterns
• Proficiency with German language.
