The Opportunity
We're on the hunt for a highly experienced and visionary Staff/Principal Software Architect to spearhead the strategic transformation of our core on-premise applications into a robust, scalable, and secure SaaS platform. This is a pivotal role that will directly shape the future of our product offerings and significantly impact our growth within the critical counter-UAS domain. Reporting directly to the VP of R&D, you'll lead the architectural vision, leveraging your deep expertise in software and system design, chiefly SaaS, to drive this critical migration.
Key Responsibilities:
- Define, champion, and execute the architectural roadmap for migrating existing on-premise applications to a modern SaaS architecture.
- Lead the architectural design and implementation of multi-tenant, highly available, scalable, and secure SaaS solutions.
- Conduct comprehensive assessments of existing on-premise applications to identify architectural dependencies, data models, integration points, and areas for refactoring or re-platforming.
- Develop detailed migration strategies, including phased approaches, data migration plans, and cutover strategies, minimizing downtime and business disruption.
- Design and evolve the target SaaS architecture, leveraging cloud-native services (e.g., microservices, serverless, containers, managed databases, message queues) and best practices.
- Establish architectural patterns, standards, and guidelines for SaaS development, ensuring consistency, scalability, and maintainability across all product lines.
- Drive the adoption of CI/CD pipelines, DevOps practices, and automated testing strategies essential for a successful SaaS model.
- Ensure architectural designs align with security best practices, compliance requirements (e.g., GDPR, SOC 2, HIPAA as applicable), and data privacy regulations specific to defense and critical infrastructure.
- Provide expert technical guidance and mentorship to engineering teams, fostering a culture of technical excellence, innovation, and continuous improvement.
- Collaborate closely with product management, engineering leads, and other stakeholders to translate business requirements into technical architectures and solutions.
- Act as a technical evangelist, staying abreast of emerging technologies, industry trends, and architectural patterns relevant to SaaS and cloud computing.
- Lead technical discussions, architectural reviews, and decision-making processes, ensuring alignment with strategic objectives.
- Architect solutions optimized for performance, scalability, and reliability in a multi-tenant cloud environment.
- Define and implement monitoring, logging, and alerting strategies to ensure the health and performance of the SaaS platform.
- Address complex performance bottlenecks and system limitations, providing strategic architectural recommendations for resolution.
- Evaluate and recommend new technologies, tools, and third-party services that enhance the SaaS platform's capabilities, efficiency, and cost-effectiveness.
- Work with cloud providers (e.g., AWS, Azure, GCP) to leverage their services effectively and optimize cloud resource utilization.
