The impact you'll be contributing to Moloco:

We seek an exceptional engineer with a strong computer science + mathematics foundation to join Moloco’s Bidder Quality team. In this role, you'll leverage the state-of-the-art technology stack that Moloco uses to drive our ML-powered performance ads business to determine bidding/pricing decisions. 

The Bidder Quality team owns the final bidding and pricing decisions that we are making for advertising campaigns. An example system component that the team builds is the bid price optimizer for first-price auction based open internet ad inventories. The team focuses on the operation and optimization of our software systems working closely with infrastructure engineering teams and machine learning teams.

As a Senior Software Engineer on our Machine Learning Engineer (MLE) team, you will lead research projects and may lead small teams of MLEs as part of a broader group of cross functional collaborators working together to solve challenging problems in a complex multi-causal environment. Your work will contribute to driving performance improvements and cost reductions as you and your team debug and investigate production issues and stabilize our core system through deep end-to-end understanding.

Here’s what you’ll be working on:

• Design and implement real-time bidding and pricing algorithms for a high-scale advertising system (7M QPS), using optimization techniques, auction theory, and machine learning fundamentals.
• Leverage adtech experience to improve auction outcomes and bidding strategies, drawing from a strong understanding of advertising ecosystem dynamics (e.g., DSPs, SSPs, auctions).
• Develop scalable and cost-efficient ad serving systems, with strong system design principles to support performance advertising at scale.
• Conduct deep root-cause analyses of ad performance issues, using statistical reasoning and quantitative methods to drive unbiased insights and corrective actions.
• Identify opportunities to optimize the ad delivery pipeline, including reducing system or serving costs while maintaining performance, using efficient algorithms and data structures.
• Collaborate cross-functionally with product, infra, and account teams to anticipate the business impact of system changes and define future product roadmaps with a strong sense of product intuition and operational awareness.
• Stay informed on system-level and data-level changes, and work with collaborators to improve infrastructure and ML model performance in response.

Basic Qualifications

• Bachelor's Degree in Computer Science with mathematical (ex, stats) coursework
• 6+ years of overall work experience (industry or postgraduate) in research related fields focused on optimization of market prices or ML systems
• Proven experience working in the adtech space—preferably with exposure to auction-based systems and real-time bidding environments.
• Strong mathematical or statistical background (e.g., optimization, probability, hypothesis testing).
• Solid understanding of business metrics, with an ability to translate technical changes into business outcomes.
• Strong system design skills, with experience in designing scalable, fault-tolerant distributed systems.
• Familiarity with cost-aware engineering practices—ability to optimize for compute, memory, and latency trade-offs.
• Hands-on coding ability in production-level codebases (e.g., C++, Java, Go, or Python).
• Working knowledge of machine learning principles, particularly in applied settings like ranking, predictions, or decision systems.
• Ph.D degree in Applied Mathematics, Operations Research, Management Science or related field a plus.
