Remote option available with quarterly office visits for one week in Vienna.
About the company
This is one of Austria's most exciting scale-ups, having recently raised more than €15 million. The team is ambitious and international, working on an exciting AI-first product with the opportunity to work with modern technologies while helping shape the future of finance.
The company empowers business leaders to make better strategic decisions in financial management, reporting and planning. Its mission is to help companies connect, analyze, forecast and automate all their financial data in one place.
It is backed by renowned investors, including Atlantic Labs, CommerzVentures and founders of Wefox, and is building the next generation of AI-native finance software.
The Mission
The company is looking for a Backend Engineer to help connect its backend and data infrastructure with LLM-powered features, agents and self-service capabilities. This role is primarily backend-focused: designing and building scalable services, APIs and business logic using Python.
Experience with data engineering (ETL/ELT pipelines, AWS data services, dimensional modelling) is a strong advantage and something the team will actively help develop further, but it is not a requirement. What matters most is strong backend engineering fundamentals combined with curiosity and a genuine interest in eventually working across data and AI product engineering as well. Backend and Data Engineering work closely together at the company, and engineers benefit from understanding both worlds. Someone who comes in strong on backend will be supported in growing into data engineering over time.
Responsibilities
Backend Engineering
Design, build and maintain scalable backend services using Python.
Develop new product features and reusable backend architectures.
Build reliable APIs, integrations and business logic.
Improve system performance, reliability, security and maintainability.
Identify technical bottlenecks and continuously improve the platform.
Participate in architecture discussions and technical decision-making.
Expose existing system capabilities through clear, secure and well-structured interfaces.
AI Product & Agent Engineering
Build production-ready product features powered by large language models.
Integrate LLMs into existing products, workflows, backend services and data systems.
Expose complex business logic and system capabilities to AI models through structured APIs, tools and agent interfaces.
Design reliable AI workflows using tool calling, structured outputs, retrieval and multi-step agent processes.
Contribute to prompt design, context management and model selection.
Cross-functional Collaboration
Collaborate closely with Product, Frontend and other engineers.
Translate product requirements into robust technical solutions.
Write clean, maintainable, well-tested and well-documented code.
Share knowledge across teams and continuously improve engineering standards.
Take ownership from problem definition through implementation and production operation.
Skills
Core Skills
Strong Python programming skills.
Experience building and operating production software.
Good understanding of object-oriented programming and software design principles.
Solid SQL knowledge.
Experience with AWS.

Experience building LLM-backed product features, RAG, embeddings or agent frameworks (e.g. MCP).
What Matters Most
The ideal candidate is curious, pragmatic and eager to learn. Being strong in both backend and data engineering from day one isn't required - what matters most is bringing strong backend fundamentals and motivation to grow.
The most important factors, above specific tech stack breadth, are:
Character and ownership
Curiosity and a strong willingness to learn
Pragmatic problem-solving
Product thinking
A strong quality mindset
Passion for building useful products
