Senior Software Engineer

Role Overview

• Design and develop high-performance distributed systems handling large-scale

bid request traffic with sub-100ms latency requirements.

• Build and optimize real-time bidding (RTB) services that evaluate targeting rules, campaign budgets, and bidding strategies in real time.
• Architect microservices and event-driven systems that support billions of daily ad transactions.
• Build systems to support server-side auctions and bid optimization strategies.
• Integrate with external Supply Side Platforms (SSPs), exchanges, and ad servers using industry standards such as OpenRTB and VAST.
• Develop robust APIs and connectors for partner integrations and supply onboarding.
• Troubleshoot and optimize integration performance with external ad tech platforms.
• Optimize systems for extreme throughput, low latency, and high reliability.
• Implement efficient caching layers and in-memory data stores using technologies such as Redis, MongoDB, etc.
• Monitor and improve system performance through observability, load testing, and capacity planning.
• Collaborate with product managers, ad operations, and partner engineering teams to deliver new platform capabilities.
• Provide technical leadership in architecture reviews, system design, and performance optimization.
• Mentor junior engineers and contribute to engineering best practices across the organization.
• Develop and maintain reliable, scalable, and efficient backend services using modern technologies and frameworks
• Write high-quality, well-tested code that is maintainable and adheres to best practices in software engineering
• Analyze data to drive decision making and assess the impact of system changes.
• Take ownership of your personal development by keeping up with the latest backend technologies, tools, and best practices. Continuously improve the development process and share knowledge within the team
• Follow agile methodologies and work in a fast-paced environment where results are quickly visible
