Full Job Description
About the Team & Role

At Auger, we are reimagining how global supply chains operate by harnessing the power of data, AI, and next-generation technologies. Central to this vision is the design and evolution of a cutting-edge data lake and AI platform, the backbone of our real-time insights, intelligent applications, and advanced decision-making capabilities. As a Principal Engineer for the Auger Platform, you will bring deep expertise in the following:

What You'll Do

  • Own end-to-end systems architecture across data pipelines, AI/ML platforms, semantic layers, and application interfaces - designing for modularity, scale, and durability from day one.
  • Build and evolve the data integration layer: ingestion, normalization, and orchestration across structured and unstructured sources, using API-first design principles (REST, GraphQL, gRPC) and real-time streaming technologies like Kafka and Apache Pulsar.
  • Architect the semantic intelligence layer: knowledge graphs, ontology design, vector embeddings, and RAG techniques that give Auger context-aware reasoning across the full enterprise data fabric.
  • Design and operate scalable AI/ML platforms for training, deployment, and model lifecycle management - integrating LLMs, embeddings, and multimodal models into production applications via MLOps tooling (MLflow, SageMaker, Databricks).
  • Drive AI into the application layer: partner with product and design to ship agentic, adaptive user experiences that surface intelligence at the moment operators need it.
  • Set architectural direction across the platform: make layer boundaries, evolution strategies, and tradeoffs explicit - and document decisions the team can execute against with confidence.
  • Raise the bar on operational rigor: fault tolerance, high availability, observability, and performance at enterprise scale are non-negotiable properties, not afterthoughts.
  • Mentor engineers on system design, coding standards, and operational excellence - and hold a high bar on what ships.


What You Bring

  • Bachelor or Master's degree in Computer Science, Engineering, or a related field.
  • 10+ years of experience in systems architecture, software engineering, and platform development - with a proven track record building scalable data platforms or AI-driven systems at enterprise scale.
  • Deep programming expertise in Python, Java, or C++, and hands-on experience building distributed systems in cloud-native environments (Azure, AWS, or GCP, including multi-cloud).
  • Fluency in real-time data processing and analytics frameworks (Spark, Kafka, Flink) and big data technologies (Databricks, Snowflake, Hadoop).
  • Advanced understanding of semantic modeling, knowledge graphs, and ontology design - including graph databases, graph embeddings, link prediction, and GNNs.
  • Hands-on experience with AI/ML pipeline design and deployment, including frameworks such as TensorFlow, PyTorch, or equivalent, and familiarity with architectural patterns including microservices, event-driven architectures, and domain-driven design.
  • Technical leadership through ambiguity: you set direction, communicate tradeoffs clearly to technical and non-technical partners, and write crisp architecture decisions when the stakes are high.
