Senior Backend Engineer / AI Engineer – Ineexa team

We at Holycode are currently looking for a passionate and experienced Senior Backend Engineer / AI Engineer to join ineexa, a Zürich based startup at the forefront of digitizing the construction industry in Switzerland.

About the company:

ineexa's cutting-edge software solution revolutionizes the way heating and sanitary installation contractors handle tenders, enabling them to save time and money through streamlined evaluation and calculation processes.

About the role:

They are looking for a talented and experienced Senior Backend Engineer with a strong focus on AI to join their growing team. In this role, you will be instrumental in developing and implementing the next generation of their AI-powered features. You will have the opportunity to work on challenging projects that have a direct impact on their product and users.

Key Responsibilities:

Your primary focus in the first 6-12 months will be on two key projects that are critical to their strategic roadmap:

• PDF Parsing: You will lead the development of a sophisticated PDF parsing solution to extract structured data from "Leistungsverzeichnisse" LVs - complex, multi-page tender documents. The goal is to achieve a high degree of accuracy in identifying and extracting key attributes such as BKP chapters, positions, variants, manufacturers, and product models, as well as understanding the contextual information within the documents.
• Product Matching: You will help design and build an intelligent product matching engine to accurately map parsed items to their extensive product database of over 1 million items. This will involve a hybrid approach, combining keyword-based search with advanced semantic search and machine learning techniques to deliver highly relevant product suggestions.

Long-term, you will also have the opportunity to work on a variety of other features and contribute to the core development of their Java-based backend.

Your Profile:

• Proven experience in building and deploying production-ready Python projects.
• Solid understanding of and hands-on experience with the APIs of major LLM providers (OpenAI, Google, Anthropic).
• Strong expertise in API design and implementation, particularly with RESTful APIs.
• Experience with cloud infrastructure, preferably AWS.
• A deep understanding of prompt engineering and experience in building and optimizing ML pipelines.
• A pragmatic approach to problem-solving, with the ability to balance quality and speed.
• Excellent communication skills and the ability to work effectively in a collaborative, interdisciplinary team.
• Fluency in English is required.

Nice to Have:

• Experience with Java (Spring Boot) is a significant plus. Knowledge of Java would be beneficial for integrating the AI features into their main application and for contributing to other parts of the product in the long run.
• German language skills would be the cherry on the cake

Why you will love working here:

• Work on challenging AI and backend problems with real impact in the construction industry
• Shape intelligent systems that turn unstructured data into valuable business insights
• A fast-paced startup environment that encourages ownership and innovation
• Working remotely (from Romania)
