Lead Engineer - Applied AI & Data Products

Innovative technologies, MVP mindset, AI-first - everyone is talking about it. With us you are right in the middle of it. Together with established clients, we develop efficient software solutions, move along product development and share our knowledge with the world. We consider ourselves AI-native: we are curious about how AI is reshaping our field and actively explore and integrate it into our daily work, from ideation to delivery. Making a real impact and delivering high standard quality while staying authentic and treating each other with respect and fairness are prerequisites for all our projects and a core value within the team.

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.
