Responsibilities

Own and maintain the software architecture with focus on interface clarity, stability, and versioning to minimize integration risk, with a focus on production type software that is easily maintainable.
Partner with appropriate stakeholders to inform system definition and oversee translation of system-level requirements into software requirements and models that meet customer, operational and performance requirements and have clear traceability to design, code and test artifacts.
Manage supplier/subcontractor software deliverables to ensure they meet team processes and integration requirements.
Lead the software engineering team’s agile delivery: facilitate sprint planning, daily stand-ups, sprint reviews/retrospectives, and remove impediments to flow.
Serve as the Agile/Delivery lead for software—own backlog prioritization with product/system owners, define sprint goals, and ensure timely delivery of integration-ready increments.
Define, document, and enforce software integration contracts (ICDs or equivalent living artifacts), data models, and message definitions in coordination with Integration & Test and Systems leads.
Ensure software is designed for testability: require unit, component, integration, SIL/HIL test artifacts with code deliveries, include observability hooks, and ensure failures are diagnosable.
Lead DevSecOps and CI/CD practices for the team: ensure pipelines support repeatable builds, automated testing, artifact traceability, and consistent deployments across dev, integration, and test environments.
Collaborate with Integration & Test to align delivery cadence to integration increments and controlled configuration baselines.
Drive verification & validation execution for software components: support development of test strategies, analyze test results, and triage defects with the team.
Establish and track delivery metrics (velocity, cycle time, quality metrics, technical debt) and use them to improve predictability and quality.
Coach and mentor engineers on agile practices, test automation, CI/CD, code quality, and observability.
Contribute to risk and issue management that affects software delivery and integration readiness; escalate when necessary to protect integration milestones.
Document integration results, test findings, and provide inputs for design reviews and readiness assessments.
