Arbeitsbeschreibung - Senior AI Engineer

Mission

Founded in 2024 by Lukas Zörner and Anil Can Baykal, Integral set out to redefine how accounting, taxation and payroll works for SMEs in Europe, starting with Germany. The company is backed by General Catalyst, Cherry Ventures, Puzzle Ventures and entrepreneurs across Europe.
As Senior AI Engineer, you will build intelligent, reliable AI systems that help SMEs navigate financial and tax operations. Own outcomes, not just output, balancing speed and craftsmanship. This role follows a hybrid schedule in our Berlin office to collaborate effectively with the team.

Core responsibilities

What you'll do

  • Build and deploy AI agents that automate accounting, payroll, and tax workflows
  • Develop LLM-based systems using modern frameworks and prompt engineering with quality control
  • Integrate AI capabilities with existing systems and APIs
  • Optimize performance, cost, and reliability of AI features

What makes it special

  • High ownership: you'll shape what we build and how we build it
  • Tight feedback loops with domain experts and customers
  • Pragmatic pace: ship, learn, iterate, without sacrificing quality

Your profile

Your Experience & Mindset
  • You have 5+ years experience in Software Engineering and AI
  • You've worked in early-stage startups or scale-ups where you had to wear multiple hats (coding, testing, UI, integrations)
  • Hands-on experience building with LLMs (OpenAI, Anthropic, or similar): APIs, prompt engineering, structured outputs, agent frameworks (LangChain, LangGraph, or similar)
  • You actively use AI coding tools like Cursor, Codex, or Claude in your daily workflow — and you can talk about how and why
  • Experience with RESTful APIs, cloud services, and testing/QA for AI systems
  • You're comfortable with ambiguity and high ownership: you'll manage multiple projects simultaneously and organize your own delivery
Preferred experience
  • You came from software engineering and have deliberately moved into AI
  • Strong Python skills: you can actually code, not just prompt

The process

We like to move fast, and with the right candidate, the entire process can be completed in less than two weeks.

  1. Intro Call with our Talent Team
  2. Deep dive Interview with our CTO & co-founder
  3. On-site Coding Interview at our Berlin office with the engineering team
  4. Founder Conversation with our CEO & co-founder

Our offer

  • Internal tooling and resources purpose-built to support agentic AI development at scale
  • 28 vacation days per year with December 24th and 31st each counting as half days
  • Urban Sports Club membership or Deutschland Ticket, your choice
  • Laptop of your choice: MacBook or Windows Pro
  • Company pension plan (betriebliche Altersvorsorge) 
  • Modern office in the heart of Berlin Prenzlauer Berg, steps away from Mauerpark
  • Hybrid working format, the best of both worlds: deep focus when you need it, and hands-on collaborative team time when it counts
  • Weekly team lunches provided by us, office BBQs and a dinner budget for late office nights past 8pm
  • A team of 50+ (and growing!) ambitious, diverse people learning and building together.
