Staff Engineer

JOB SUMMARY

This role focuses on building and supporting fuels back-office systems that power 7‑Eleven’s wholesale, fleet, supply, accounting, and transportation operations. As Staff Engineer for Fuels Supply, you will design, build, and optimize the Supply Integration Hub, a core platform orchestrating data and workflows across the fuels supply chain. Implement and integrate the Right Angle ETRM platform and the BestBuy supply optimization solution.

KEY DUTIES AND RESPONSIBILITIES

• Technical Design & Architecture: Design and architect for the Supply Integration Hub and related fuels supply applications. Own technical decisions for cloud-native microservices, API integrations, event-driven pipelines, and data flows between internal systems and external platforms (Right Angle, BestBuy, OPIS, DTN).

• Hands-On Development: Actively contribute production code in Java Spring / Spring Boot, Node.js, React, or Python. Build and maintain RESTful APIs, Kafka-based messaging, and ETL pipelines that power the fuels supply ecosystem.

• Integration Leadership: Drive integration architecture between the Supply Integration Hub and COTS platforms. Collaborate with vendor implementation teams to define interface contracts, data mappings, and reconciliation processes.

• Code Quality & Engineering Standards: Establish and enforce coding standards, design patterns (MVC/MVVM), and peer-review practices. Champion test-driven development, automated testing, and CI/CD best practices.

• Mentoring & Technical Guidance: Mentor engineers on modern engineering practices, cloud architecture, and domain-specific knowledge. Conduct architecture reviews, pair programming sessions, and knowledge-sharing forums.

• Cloud & DevOps: Design and maintain cloud infrastructure on Azure/AWS, including container orchestration (Kubernetes/EKS), infrastructure-as-code, and observability (monitoring, alerting, logging).

• Data Architecture: Guide data modeling, query optimization, and performance tuning across PostgreSQL, MS SQL, and NoSQL data stores. Ensure data integrity across the supply chain data landscape.

• Agile Delivery: Participate in and support Agile/Scrum ceremonies. Provide effort estimates, decompose epics into stories, and ensure predictable, high-quality delivery across sprints.

• Stakeholder Communication: Translate complex technical concepts for business partners and leadership. Communicate risks, trade-offs, and progress with clarity and transparency.

• Innovation & Continuous Improvement: Stay current with emerging technologies including AI/ML, contribute to internal engineering communities, and champion experimentation that improves developer productivity and platform capabilities.
