Senior Site Reliability Engineer, AWS/Datacenter Hybrid

Are you ready to revolutionize the advertising industry? 

At Cognitiv, we are not just another AdTech company-we are industry trailblazers redefining media buying with our Deep Learning Advertising Platform. Since 2015, we have harnessed the power of cutting-edge deep learning technology and data science to transform how brands connect with their customers. Our mission? To bring intelligence to advertising and deliver unparalleled precision, relevance, and impact at scale. 

With our innovative platform, advertisers enjoy unprecedented flexibility-whether it is activating Dynamic Deals through their preferred DSP, leveraging our managed service DSP, or utilizing our industry-first ContextGPT product. As a part of Cognitiv, you will be at the forefront of AI-driven advertising solutions, driving change and achieving remarkable growth in a rapidly evolving industry.

Now, we’re growing!

We are looking for a Senior Site Reliability Engineer to strengthen our AWS infrastructure and improve service management across Cognitiv. Our immediate challenge is to scale and harden our AWS environment as we continue expanding our hybrid cloud footprint. Past that, we are a rapidly growing organization and need to continue to move toward industry best practices. This role demands an experienced engineer with the interest to rapidly learn our environment and help drive our long-term service management roadmap.

This role partners closely with our datacenter-focused SRE, so while deep, hands-on AWS expertise is the priority, working familiarity with datacenter operations is important so you can help provide multi-DC coverage when needed.

Location: This position will be in our Bellevue, WA office with a hybrid work schedule of 3 days in office (Mon/Tue/Wed) and 2 days remote (Thursday/Friday).

Responsibilities

• Design, implement, and maintain infrastructure across our AWS environment, serving as the primary owner of our cloud footprint.
• Evaluate our existing AWS architecture (compute, networking, security) and ensure we are set up for long-term scalability and growth.
• Work across engineering and product teams to scope projects tightly to core business requirements.
• Drive engineering-wide efforts to improve company service management around deployments, monitoring, and disaster recovery.
• Support and help maintain our co-located datacenter deployments alongside our datacenter-focused SRE, providing coverage as needed.

Our Stack

• Hosting: AWS and Equinix colocation.
• Monitoring: Datadog (migrating off Prometheus).
• Infrastructure as Code: Terraform and Ansible.
• Compute: Primarily raw EC2 instances and bare-metal machines, with a small footprint of Kubernetes.

Requirements

• Deep knowledge of AWS infrastructure, networking, and management practices.
• 10+ years of experience in operations, software engineering, or as an SRE.
• Working knowledge of modern datacenter practices, with the ability to support multi-DC deployments as needed.
• Proven experience with infrastructure as code
• Proficiency with Python and Bash.
• An independent self-starter who looks at the big picture, takes ownership, and independently seeks out new challenges with creative solutions.
• A constructive, supportive team player, with good communication and interpersonal skills.

Preferred Qualifications

• AWS certifications (e.g., Solutions Architect, SysOps Administrator) 
• Experience with hybrid cloud/on-prem solutions.
• Hands-on experience building out datacenters.
• Willingness and interest to travel 1-2 times per quarter.
