Stord is revolutionizing the logistics industry with our cloud-based supply chain platform. Our AI team is building next-generation features like Demand Planning, predictive analytics, and intelligent automation that leverage both traditional ML models and cutting-edge LLM capabilities. We need an experienced Elixir engineer (ideally, a true polyglot that looks at languages as tools) who can seamlessly integrate these AI capabilities into our core platform.

We are seeking a skilled AI-focused Senior Software Engineer who combines deep technical expertise with practical AI/ML integration experience. You'll work directly with our Director of AI Products to architect and build AI-powered features, collaborate with Data Scientists to understand model requirements, and partner with ML Engineers to create seamless integration between our ML infrastructure and core services. This is a hands-on role where you'll build the backbone services that make AI features accessible across our entire platform. In this role, you'll be instrumental in making AI a first-class citizen in our broader platform. You'll work on critical features like demand forecasting APIs, intelligent routing services, and real-time prediction engines, with the opportunity to shape how AI integrates with our core logistics platform (and what tools we use internally). This is a unique opportunity to have a massive impact on a team that's transforming supply chain operations through AI.

Platform Architecture & Scalability:

• Design distributed systems that can handle millions of AI-powered logistics operations
• Implement proper monitoring, alerting, and observability
• Build developer tools and abstractions that make AI capabilities easy for other engineers to integrate
• Create configuration management and feature flagging for experiments
• Optimize performance and costs across the platform

Cross-functional Collaboration:

• Partner with the Director of AI Products on architecture decisions and technical strategy
• Collaborate with Data Scientists to understand model inputs, outputs, and constraints
• Work with the ML/Data Engineers to ensure seamless model deployment integration
• Support product teams in implementing AI features within their domains
