The Opportunity

We are seeking an accomplished Senior Software Architect to join our Digital Signage Cloud Team. This strategic role is pivotal in guiding the architectural vision and technical roadmap for our global cloud-based digital signage platform. You will drive high-level architectural design, scalability, security, and performance optimizations, working closely with stakeholders across engineering, product management, and leadership. Practical experience or strong enthusiasm for Artificial Intelligence—particularly Large Language Models (LLMs), generative AI, and agentic coding tools—is highly desirable.

Key Responsibilities: 

• Establish and uphold architectural standards that ensure scalability, maintainability, security, and performance for our digital signage cloud platform.
• Own the platform architecture roadmap, ensuring it aligns with strategic business goals and evolving product needs.
• Design and evolve cloud-native architectures leveraging AWS serverless services such as Lambda, API Gateway, DynamoDB, Cognito, and Step Functions, with a strong emphasis on scalability, cost-efficiency, and resilience.
• Partner with engineering teams to guide solution design, resolve complex technical challenges, and ensure alignment with architectural direction.
• Collaborate cross-functionally with product managers, designers, and business stakeholders to translate requirements into robust, future-proof technical solutions.
• Evaluate and recommend emerging technologies, fostering a culture of innovation by piloting and integrating cutting-edge tools and frameworks into the platform.
• Mentor and coach engineers across teams, building architectural awareness, elevating technical skills, and driving adoption of best practices.

 Skill & Experience Requirements:

• Bachelor’s degree in Computer Science or related discipline; Master's preferred.
• 9+ years of software development and architecture experience.
• Proven track record architecting large-scale cloud-native applications and solutions.
• Practical experience or strong enthusiasm for AI integration and generative technologies.
• Expert-level understanding of AWS Cloud architecture, especially in serverless ecosystems (Lambda, API Gateway, DynamoDB, Cognito, Step Functions, S3, SNS/SQS).
• Strong foundation in modern web development, including TypeScript, Node.js, React, and event-driven architecture.
• Demonstrated experience designing and operating multi-tenant SaaS platforms with a focus on data isolation, RBAC, and observability.
• Proficiency in authentication/authorization protocols, including OAuth2, OpenID Connect, and integration with identity providers like Okta and AWS Cognito.
• Hands-on experience with AI and ML frameworks, including Generative AI, LLMs, and tools like Cursor, Windsurf, or equivalents.
• Strong understanding of DevOps practices, CI/CD tooling (e.g., GitHub Actions, CodePipeline), and infrastructure observability (CloudWatch, Prometheus, Grafana, ELK stack).
• Exceptional problem-solving skills, system thinking, and ability to articulate complex technical ideas to both technical and non-technical stakeholders.
