Senior Cloud Architect

The Role

TripleLift is seeking a Senior Cloud Architect to help shape the infrastructure that underpins one of adtech's most sophisticated programmatic platforms. This role is built for a technically deep, hands-on architect who can move fluidly between designing elegant cloud solutions and rolling up their sleeves to bring them to life.

You'll work at the intersection of architecture, engineering, and security—partnering with cross-functional teams to design systems that are scalable, resilient, and built for the demands of real-time bidding at massive scale. If you're energized by hard infrastructure problems, passionate about cloud-native design, and eager to leave a lasting technical mark on a high-growth platform, this is your seat at the table.

Responsibilities

• Design and deliver cloud architecture solutions on AWS that meet the performance, reliability, and security requirements of TripleLift's exchange and data platforms
• Develop and maintain architectural standards, patterns, and reference designs that engineering teams can build confidently against
• Partner with Platform, Security, and Data Engineering teams to assess infrastructure needs and translate them into actionable, scalable designs
• Lead the evaluation and adoption of new cloud services and technologies, providing clear recommendations grounded in technical and business context
• Drive infrastructure as code practices using Terraform or equivalent, ensuring consistency, repeatability, and auditability across environments
• Collaborate with DevOps and Engineering teams to integrate cloud architecture best practices into CI/CD pipelines and deployment workflows
• Conduct architectural reviews and design critiques, providing substantive, constructive feedback that raises the bar across the team
• Identify and address performance bottlenecks, reliability risks, and cost inefficiencies in existing and proposed cloud systems
• Support cloud security and compliance efforts, including IAM design, network segmentation, encryption strategies, and adherence to SOC2 and PCI standards
• Mentor engineers on cloud-native design principles and serve as a go-to resource for complex infrastructure decisions

What You Bring

• 10+ years of experience in cloud infrastructure or platform engineering, with at least 3 years focused on cloud architecture
• Expert-level proficiency with AWS and its core services (EKS, EC2, RDS, S3, VPC, IAM, CloudFront, and beyond)
• Strong command of infrastructure as code (Terraform preferred) and modern CI/CD tooling (GitHub Actions or equivalent)
• Experience designing for high-throughput, low-latency workloads—adtech, fintech, or media platform experience is a meaningful plus
• Solid understanding of cloud security principles, including network architecture, IAM, secrets management, and compliance frameworks (SOC2, PCI, NIST CSF)
• Proficiency in at least one scripting or systems language (Python, Go, or similar) for automation and tooling
• Strong architectural intuition with the ability to weigh tradeoffs across performance, cost, complexity, and maintainability
• Clear, confident communicator who can engage equally well with engineers and business stakeholders
• Self-directed and comfortable driving work forward with limited oversight in a fast-moving environment
• A continuous learner who keeps a close eye on the evolving cloud landscape and brings that knowledge back to the team
