Product Engineering Intern
Our mission
We are building the operating system for the €20B German tax advisory industry.
At Limetax, we acquire established tax advisories and transform them into high\-performing, technology\-enabled businesses. Instead of building software in isolation, we work directly on real companies, real workflows, and real data.
Our goal is simple: reduce manual work in tax advisory and redefine how tax operations are run — through applied AI.
Your mission
As a Product Engineering Intern, you will work on systems that improve and automate real operational workflows inside modern tax firms.
You won’t be working on theoretical side projects or internal mockups. From day one, you will contribute to systems and workflows that are actively used in production across accounting, payroll, reporting, and client operations.
At the same time, this internship is designed to give you hands\-on exposure to how scalable operational systems are built in practice. You will work closely with founders, operators, engineers, and tax professionals while gradually taking ownership of projects with close support from the team.
Your work will directly impact how tax professionals operate on a daily basis.
How your day\-to\-day will look like
Analyze Operational Workflows
Understand and map workflows across accounting, payroll, reporting, and client communication.
Build Workflow Systems
Design and improve operational systems using internal software, APIs, automation tools, and AI.
Identify Bottlenecks
Analyze repetitive work, operational inefficiencies, and workflow failure points.
Prototype Fast
Build MVPs and internal tooling to validate operational improvements quickly.
Improve Operational Reliability
Help turn fragile manual workflows into scalable, repeatable systems.
Operate in Production
Monitor, evaluate, and continuously improve systems running in real operational environments.
Collaborate Closely
Work directly with founders, operators, engineers, and tax professionals to improve how work gets done.
Think in Systems
Focus on processes, scale, reliability, and operational excellence — not just individual tasks.
