Senior Software Engineer – AI Infrastructure

About Arango

At Arango, we believe the first generation of enterprise AI missed something essential: context. LLM models are powerful, but they didn’t understand the context needed to deliver accurate answers.

Arango provides a trusted data foundation for the next wave of Enterprise AI with graph-based Contextual AI - transforming enterprise data into a System of Context that truly represents the business, so LLMs can deliver better outcomes with unlimited scale and cost efficiency.

The Arango AI Data Platform gives developers a single, integrated environment to build and scale AI-powered applications without the complexity of stitching together multiple databases and tools. At its core is a massively scalable multi-model database that unifies graph, vector, document, and key-value data with full-text, geospatial, and vector search — creating the System of Context, the bridge between enterprise data and LLMs.

We’re a global team based in California and Cologne, united by curiosity, collaboration, and a passion for helping developers, data engineers, and technology leaders innovate faster and smarter with AI. Trusted by NVIDIA, HPE, the London Stock Exchange, the U.S. Air Force, NIH, and Articul8, Arango powers enterprise AI with context, confidence, and scale. We are a proud member of the NVIDIA Inception Program and the AWS ISV Accelerate Program. 

If you’re excited about shaping the future of Contextual AI, come build with us.

About the Role

We are looking for a senior, hands-on software engineer to help maintain, stabilize, and debug our AI infrastructure. This role has high ownership and requires deep technical problem-solving skills in production environments. The most important qualification is not a specific language, but a strong understanding of how complex software systems actually behave in production.

Key Responsibilities:

• Maintain, develop and stabilize AI infrastructure services
• Architect and implement foundational services and shared libraries that scale our entire AI infrastructure ecosystem.
• Debug complex, non-obvious production issues across application, process, network, and memory layers
• Systematically analyze, isolate, and resolve failures in unclear scenarios
• Improve observability, profiling, and tracing across services
• Work with distributed microservices and internal platforms
• Operate and improve systems running on Docker, Kubernetes, and Helm
• Support CI/CD pipelines (CircleCI), testing, and security-relevant components
• Work with MLflow, Triton, and distributed Python modules

Core Requirements:

• Senior-level experience (minimum 5+ years)
• Passion for working with cutting-edge technologies in a fast-moving AI environment, including LLM-based workflows and pipelines
• Comfortable working independently in a fast-paced, evolving environment
• Strong debugging skills in complex, distributed systems with the ability to identify root causes when failures are ambiguous
• Solid understanding of how software behaves in production environments
• Experience designing and operating microservices, distributed systems, and databases
• Proven experience building and scaling high-availability services
   

Core Technology Stack

• Python (primary language) - 5+ years
• Docker, Kubernetes, Helm - 5+ years
• CI/CD pipelines and testing frameworks (e.g., CircleCI)
• Observability tools: metrics, logs, tracing, and profiling
• Exposure to AI/ML infrastructure, including tools such as MLflow and Triton

Nice to Have:

• Customer-facing experience, including proofs of concept (PoCs) or technical demos
• Experience with AI/ML infrastructure and orchestration, i.e., MLflow and Triton
• Cross-language debugging experience
• Familiarity with Rust
• Experience working with databases, NoSQL, multi-model, or graph databases
• Knowledge of Retrieval-Augmented Generation (RAG) and GraphRAG concepts
• Understanding of graph algorithms and graph-based data modeling
