Lead Engineer - Applied AI & Data Products

Description

Are you excited about building smart, data-driven products using the latest AI technologies — and about owning the technical and customer-facing responsibility that comes with it? At SQUER, we help our customers unlock the potential of AI through real-world software solutions — not by building custom models from scratch, but by applying LLMs, cloud-native AI services, and smart engineering. Join our Product Delivery Unit and lead how applied AI enhances modern digital products.

Your tasks

• AI-Powered Product Architecture: Design and own the architecture of AI-enhanced software products using modern cloud services and frameworks (e.g., Azure OpenAI, AWS Bedrock, LangChain).
• Applied LLM & Expertise: Apply Large Language Models (LLMs), cognitive services, and related technologies to solve complex, high-impact customer problems independently.
• Customer Consulting: Lead workshops and technical discussions with product managers, designers, and customer stakeholders, representing SQUER with confidence and identifying where AI adds measurable value.
• Scalable Systems Design: Architect scalable data pipelines and APIs that power intelligent features in production-grade environments, taking full technical ownership.
• Technical Leadership & Mentorship: Guide and develop engineers within your team, shape our applied AI engineering practices, and ensure project and team success.
• Thought Leadership: Represent SQUER's applied AI expertise externally — through client relationships, internal knowledge-sharing, or community engagement.

Your qualifications

• Extensive Software Engineering Experience: Several years of hands-on and architectural experience in software engineering (e.g., Python, Java, C#, JS/TS, or similar).
• Applied AI Depth: Proven, independent experience applying AI services in production (e.g., LLMs, NLP APIs, cognitive services), not just experimenting.
• Cloud Platform Ownership: Confident designing and deploying AI-driven features on AWS, GCP, or Azure at production scale.
• Data & API Architecture: Strong understanding of data processing, APIs, and databases (SQL & NoSQL), with the ability to make architectural decisions independently.
• Leadership & Mentorship: Ability to guide, coach, and develop other engineers, and to take responsibility for a team's delivery and satisfaction.
• Customer-Facing Confidence: Comfortable representing SQUER independently to customers with a high degree of professionalism.
• Languages: Fluency in German and English.
