Senior Scrum Master

Trans Core (TRN), a subsidiary of ST Engineering, is
actively seeking an experienced Senior Scrum Master to join our Software Development team. This position will be based in Nashville, TN, or Austin, TX.

As a Senior/Lead Scrum Master at Trans Core, you will champion the optimization of the LeSS Agile delivery process across multiple cross‑functional teams building and modernizing mission‑critical Toll and Intelligent Transportation Systems. You will provide leadership and coaching to Product Owners and engineering teams aligned to Trans Core’s Infinity®, MPS/Host, roadside systems, and emerging AI/ML capabilities. This role is both strategic and hands‑on—driving delivery excellence, enabling team self‑management, improving cross‑tier architecture flow, and supporting platform transformation (containerization, cloud alignment, automation).

You will be a key force in elevating Agile maturity across the organization while ensuring predictable, high‑quality delivery across complex hardware‑software ecosystems. This is a hybrid position (onsite/remote) and occasional travel will be required.

• Lead Agile delivery for 6-8 Scrum teams across lane systems, Infinity UI/services, MPS/Host pipelines, OCR/ML workflows, and deployment readiness.
• Coach and mentor other Scrum Masters if added in the future, providing guidance, training, and feedback to elevate overall Agile maturity.
• Ensure consistent application of Agile principles across teams and alignment with Trans Core’s engineering model.
• Recommend and guide adoption of better/best practices when appropriate.

• Platform modernization
• Shift to containerized and cloud‑ready services
• Audit automation and ML model lifecycle improvements

• Work directly with:
• Architecture (platform strategy, service modernization)
• Hardware Engineering (controller firmware, ATD/AVI integrations)
• Field Deployment (baseline loads, parameter packages)

• Anticipate risks early, escalatelike appropriate, and help eliminate recurring bottlenecks.

• Influence backlog structure and flow—not just facilitate it.
• Partner with Project Teams, Product Owners to ensure:
• Clarified priorities across teams

Roadmaps are realistic and aligned with engineering capabilities.

• Lead organization‑wide improvement initiatives:
• CI/CD optimisation

• Increased automation (functional, integration, synthetic lane tests)
• More efficient regression cycles (especially for AI/ML model updates)
• Better SME knowledge capture and parameter management
• Establish repeatable frameworks for retrospectives, metrics, and disciplined execution.

• Facilitate alignment between Product, R&D, PMO, Deployment, QC/QA, and Field Services.
• Improve transparency around sprint goals, risks, dependencies, and release readiness.
• Act as a trusted advisor to engineering leadership regarding delivery health.

• Develop engineering teams into highly accountable, predictable units capable of:
• Early risk identification
• Stable sprint commitments
• Reduce team reliance on escalation and external intervention.

• Lead Agile maturity efforts across R&D and Deployment.
• Mentor teams through:
• Cloud‑native adoption
• Dev Ops maturity assessments
• ML/AI lifecycle integration
• Help establish a culture of transparency, lean thinking, continuous learning, and experimentation.

• A BS in Computer Science, Software Engineering, or a related field. An equivalent combination of education and experience may be considered.
