Senior Software Engineer, Ads Quality

Moloco is an AI-native performance advertising company, bringing the power of AI advertising to the open internet. Founded in 2013 by machine learning engineers who had built AI advertising systems inside the world's largest technology companies, Moloco began from a shared mission: to build that same engine for the open internet.

Today, Moloco is one company with two businesses, built on the same compound AI system. Moloco Ads is our AI-native performance advertising platform, helping mobile app marketers acquire, retain, and re-engage high-value users across the open internet. Moloco Commerce Media is our AI-native retail media platform, enabling retailers and marketplaces to turn their platforms into thriving ad businesses. Both are powered by CARA (Compound Ad Recommendation Architecture), the AI system behind every Moloco product.

At Moloco, we bring together those who've already solved hard problems and those with the drive to. Here, we work on some of the complex problems in AI advertising, at a scale and level of sophistication very few companies can offer. Come build what's next.

Help advance Moloco’s Ads Quality systems so advertisers achieve stronger performance and end users see more relevant, trustworthy ads. This role elevates the precision, fairness, and efficiency of our machine learning–driven ad marketplace across Moloco’s products.

This role is for an experienced engineering tech lead who can act as a vertical lead: someone who can connect the dots across engineering, data science, product, sales, marketing, and customers to improve performance end to end.

• Lead vertically focused quality initiatives from concept through launch, measurement, and iteration
• Own problems end to end, from identifying advertiser pain points to driving cross-functional execution across the stack
• Partner closely with Product, Data Science, Engineering, TPM, Sales, Marketing, and other stakeholders to ensure solutions are technically strong and commercially impactful
• Translate customer and market needs into product and engineering priorities
• Step into ambiguous, fast-moving situations and improvise effectively when new constraints or opportunities emerge
• Represent the technical and product context for key advertisers, helping internal teams and external partners align on how to improve performance
• Contribute hands-on across Moloco’s stack, with exposure to areas such as bidding logic, advertiser-facing product surfaces, and quality systems
• Help incubate new ideas, run experiments, and turn successful vertical learnings into scalable product capabilities
• Communicate clearly and persuasively, bringing partners along the journey and building alignment across a broad set of functions

• Senior, hands-on engineer
• Proven ability to lead large, ambiguous initiatives end to end
• Strong communicator who can influence across technical and non-technical audiences
• Comfortable operating with more breadth than depth, and switching between strategic, technical, and operational work as needed
• Track record of driving outcomes directly through both technical contribution and coordination
• Strong preference for ads or ad tech experience
• Experience working on ads quality, traffic quality, search quality, feed quality, or adjacent quality-focused systems
• Experience leading a vertical, domain, or product area where success depended on aligning multiple teams around customer and business outcomes
• Experience in environments where rapid experimentation, analysis, and ideation are core to the way teams work

• Lead with Humility: Everyone’s voice is respected, valued, and heard. We win, lose, and learn together. Accountability and feedback are essential to our success. 
• Uncapped Growth Mindset: We see all situations as opportunities to learn, grow, and improve as individuals and as an organization. We seek diverse perspectives, encourage curiosity, and promote experimentation to push the boundaries of what’s possible. 
• Create Real Value: We pursue the most impactful opportunities with intensity and rigor. We take intelligent risks and make disciplined trade-offs to maintain deep focus. We help our customers win by delivering durable value. 
• Go Further Together: We’re one team working towards one vision. We collaborate proactively and inclusively, involving the right people at the right time and in the right way. We strive to create a more equitable workplace. We won’t let each other fail.
