About the Role

We are seeking an experienced backend engineer to join a global advertising technology organization responsible for building and operating high-scale advertising infrastructure.

The team develops and maintains a centralized advertising delivery platform supporting a broad portfolio of digital products and services. The platform enables advertising monetization across e-commerce, financial services, media, communications, and other digital experiences.

You will take ownership of major platform capabilities, working closely with product managers, engineering teams, operational teams, and other stakeholders to design, build, deploy, and continuously improve advertising technology products.

This is a hands-on engineering role with opportunities to influence technical architecture, system performance, reliability, and product development.

What You'll Do

Backend & Platform Engineering

• Design, develop, and maintain backend services supporting a large-scale advertising delivery platform.
• 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
• PostgreSQL
• Other comparable RDBMS technologies
• Professional/business-level English communication skills.

Preferred Experience

Experience in any of the following areas will be highly valued:

• Practical experience with BigQuery, Pub/Sub, Dataflow, GKE, or other GCP technologies.
• 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.
