[Hiring] Software Engineer @Neuplaner Audit GmbH Wirtschaftsprüfungsgesellschaft

Role Description

We are growing our dev team – along several routes at once. Next to our team, we see our differentiation in technology. Not as a support function, but as the thing that makes the group worth more than the sum of its parts. We are building two things for that:

• Neuplaner Vision : The group's second brain – you ask a question in plain language and get an answer grounded in our own documents, mail and meetings, with citations back to the source. Specific workflows sit on top of it, today at holding level, next inside the firms with their own tenant and their own data.
• Tech-enabled talent strategy : Makes the capability of several hundred advisors visible and usable across all firms – a new codebase, where you write the first lines.

Stack:

• Python 3.12 / FastAPI
• PostgreSQL 16 with pgvector
• React + TypeScript in strict mode
• Claude API called directly (no LangChain)
• AWS

On the talent codebase:

• Nest.js
• Angular
• MongoDB

This is applied AI engineering – we call models, we do not train them. Roughly 200,000 lines, two live installs, real users, small reviewed pull requests.

How you can join:

• As a working student
• On an internship
• Permanently
• As a contractor
• A thesis is a possible entry too

No ML background required, no prior tax or M&A knowledge. FastAPI, pgvector and LLM APIs we can teach you. In doubt, just apply.

Qualifications

• No ML background required
• No prior tax or M&A knowledge

Requirements

• Willingness to learn FastAPI, pgvector, and LLM APIs

Benefits

• Opportunity to work on innovative technology
• Flexible entry routes (working student, internship, permanent, contractor)
