About The Position

We are seeking a Senior Software Engineer to join Thales in Austin, TX, serving as a senior technical leader in the design, evolution, and governance of core software products supporting state and law enforcement agencies. This role provides hands-on technical leadership, combining active software development with ownership of baseline and reference software solutions that underpin multiple customer programs and serve as the foundation for project delivery across the organization. Operating as a recognized technical expert, you will lead the definition of complex software architectures, establish engineering standards, and drive technical decision-making for mission-critical, secure, and scalable systems. In close collaboration with engineering leadership, program stakeholders, and the technical board, this role shapes innovation within core products, anticipates emerging technical and security needs, and ensures solutions meet stringent performance, reliability, and regulatory requirements. While remaining hands-on, the Software Engineer leads and develops core products that provide reusable foundations prioritizing simplicity and extensibility to enable project-specific capabilities without adding unnecessary complexity.

• Deploy, configure, and validate core products and solutions in cloud environments, ensuring alignment with architectural guidelines and operational requirements.
• Define and enforce engineering best practices, coding standards, and design patterns to ensure the delivery of secure, scalable, and high-quality software across multiple projects and teams.
• Drive resolution of complex, high-impact technical issues, including performance, scalability, and reliability challenges, performing root-cause analysis and defining sustainable corrective actions.
• Continuously evaluate emerging technologies, tools, and industry trends, recommending and driving adoption where appropriate to advance product capabilities, security posture, and development efficiency.
• Partner with engineering leadership and the project design authority team to translate business, customer, and regulatory requirements into coherent technical architectures and implementation strategies.
• Lead and influence technical reviews with the technical board, including architecture and code reviews, providing expert guidance and decision-making to ensure consistency, quality, and long-term product health.
• Establish and maintain authoritative technical documentation, including architecture descriptions, reference designs, and technical standards, to support product scalability and knowledge transfer across teams.
• Operate as a recognized technical expert, collaborating with Software Engineers and Architects to guide technical direction while remaining hands-on.
