• Build and enhance backend APIs, data-processing systems, and core advertising functionality.
• Lead the development of selected platform features while collaborating closely with other engineers.
• Take end-to-end ownership of assigned features, from technical design through implementation, deployment, and ongoing maintenance.
• Define technical requirements and architectural approaches for new capabilities.
• Design systems with consideration for overall platform architecture, scalability, response times, and interactions with existing functionality.

Reliability & Operations

• Maintain high availability and stability of production advertising systems.
• Implement appropriate monitoring, alerting, and operational safeguards for newly developed functionality.
• Investigate production issues, identify root causes, implement corrective solutions, and establish preventative measures.
• Analyze application and infrastructure logs within cloud environments.
• Contribute to improving operational efficiency through automation and software development.
• Support the maintenance, refactoring, and modernization of long-running and legacy systems.

Collaboration & Technical Leadership

• Work closely with product managers and stakeholders to translate business requirements into technical solutions.
• Communicate with teams outside of engineering to understand requirements and resolve issues.
• Provide technical guidance and support to other engineers.
• Explain technical designs, project progress, incidents, and root causes clearly to non-technical stakeholders.
• Break complex engineering initiatives into manageable tasks, prioritize work effectively, and consistently deliver against objectives.
• Proactively raise risks and uncertainties and collaborate with team members to resolve them.

Required Qualifications

• 5+ years of professional software development experience, preferably including experience developing advertising systems.
• Strong proficiency in Golang.
• Experience developing and performance-tuning large-scale web applications.
• Hands-on experience operating applications on at least one major public cloud platform:
• Google Cloud Platform (GCP)
• Amazon Web Services (AWS)
• Microsoft Azure
• Strong knowledge of relational database systems such as:
• MySQL

• Development experience with SSP or DSP platforms.
• Experience improving products based on customer or user feedback.
• Experience maintaining, refactoring, and modernizing mature production systems and legacy codebases.
• Experience using software engineering and automation to improve operational efficiency.
• Strong incident investigation and troubleshooting skills, including:
• Initial issue investigation
• Problem isolation
• Root-cause analysis
• Solution implementation
• Preventative measures
• Experience analyzing production logs using tools such as Cloud Logging or CloudWatch.
• Ability to communicate complex technical specifications and system behavior to non-technical stakeholders, both verbally and in writing.
• Strong task-management and prioritization skills, with the ability to break complex projects into achievable deliverables.
• A collaborative engineering mindset, including proactively escalating risks and helping teammates resolve technical challenges.
