About the role
As a Senior Software Engineer on the Ads Creative team, you will lead the systems that power how creatives are ingested, processed, and delivered across Moloco Ads. Your work will directly impact ad performance, experimentation velocity, and the quality of creative experiences for advertisers and end users on a global scale.
What You Will Do
- Lead the design and implementation of core backend services and pipelines for creative ingestion (images, video, HTML, etc.), validation, transformation, rendering, and delivery.
- Act as technical lead on medium‑ to large‑scale projects, breaking down ambiguous creative requirements into clear technical designs, milestones, and execution plans.
- Architect and evolve services that manage creative metadata, versioning, policy/quality checks, and runtime selection, ensuring high availability and low latency for online ad serving.
- Collaborate closely with Product, Design, Ads Infrastructure, and Machine Learning teams to define how creative assets are prepared, scored, and experimented on to maximize advertiser performance.
- Build and improve tooling and services that support creative A/B testing, dynamic templates, and performance analytics, enabling rapid iteration on creative strategies.
- Work with data and infra partners to design reliable creative data pipelines, ensuring that logging, feature generation, and reporting around creatives are correct, timely, and cost‑efficient.
- Drive engineering best practices in testing, observability, reliability, and on‑call operations for creative systems, and proactively address tech debt that limits future innovation.
- Mentor and support junior engineers, providing design guidance, review, and context that help them grow their skills and impact.
Basic Qualifications
- BS/MS in Computer Science or a related technical field, or equivalent practical experience.
- 8+ years of software engineering experience, with significant backend or platform experience in production systems.
- Proficiency in one or more modern programming languages such as Java, Go, Kotlin, C++, or Python, and experience building large‑scale distributed systems or high‑throughput services.
- Strong system design skills, with a track record of owning and leading complex services or features end‑to‑end, across multiple components or teams.
- Deep experience designing, building, and operating web services / APIs and working with relational or NoSQL databases (e.g., MySQL, PostgreSQL, Bigtable, BigQuery).
- Proven experience acting as a technical lead: scoping projects, defining technical approaches, coordinating with other engineers, and delivering on time with high quality.
- Demonstrated ability to collaborate with cross‑functional partners (Product, Design, Data, ML, Operations) and to influence product and technical decisions.
- Fluent verbal and written communication skills in English, including the ability to explain complex technical topics to diverse audiences.
Preferred Qualifications
- Experience building systems for creative or media processing pipelines, such as ingestion, validation, transformation, optimization, or content moderation.
- Experience with real‑time ad serving or recommendation systems, especially where creatives or assets are selected dynamically at runtime.
- Familiarity with digital advertising / AdTech, including how creative quality and variation impact performance, experimentation, and advertiser outcomes.
- Hands‑on experience with cloud and big‑data technologies (e.g., GCP, BigQuery, Dataflow, Kafka, Beam/Spark) and integrating them into production services.
- Experience designing experiment and measurement frameworks for creatives (e.g., A/B tests, multi‑armed bandits, creative scoring/selection policies) in partnership with ML teams.
- Experience applying or integrating GenAI or automation for creative transformation, auto‑generation, QA, or classification is a strong plus.
- Track record of mentoring engineers, improving team‑wide engineering practices, and contributing to a positive, inclusive team culture.

The impact you'll be contributing to Moloco:
Creatives are one of the highest-leverage levers in Moloco Ads: they shape what users see, how they interact, and ultimately how much value advertisers extract from our platform. As formats grow more complex (video, playables, rich HTML) and surfaces diversify across exchanges, SDK, and new inventory types, our creative systems must do more than just serve assets — they must learn, adapt, and guide advertisers toward better outcomes.
This space sits at the intersection of ML/bidding, supply, and UI/UX for advertisers. Strong product decisions here directly influence company toplines, ROAS and advertiser retention. At the same time, weak creative strategy can quietly erode performance, create operational noise, and diminish trust in our optimization systems. We need a Staff Product Data Scientist who can bring structure, rigor, and long-term thinking to this inherently noisy problem space.
The person will be the analytical and product thought partner for the Creatives team, owning the data narrative across ideation, launch, and iteration of creative features and strategies. This is not a “support” role; it is a co-owner of the creative roadmap.
Here’s what you’ll be working on:
This role is critical to ensuring that Moloco’s creative systems become a long-term competitive advantage, not just a collection of formats and features.
- Be recognized as a thought leader in the creative domain, someone whose perspective is actively sought when making high-stakes product calls. For example, influence which creative problems we choose to solve, not just how we measure the outcomes.
- Establish a trusted, repeatable framework for measuring creative impact that the organization rallies around. This will enable PM/ENG to ship creative features faster and with more confidence, backed by well-designed experiments and clear success criteria.
- Reduce ad-hoc fire drills by building durable monitoring, diagnostics, and documentation that make creative performance and adoption more transparent.
Minimum Qualifications
- Bachelor’s degree in a quantitative field (e.g., Statistics, Computer Science, Economics, Physics) or equivalent practical experience.
- 8+ years of experience (or PhD + 6 YoE) in data science, product analytics, or a closely related quantitative field, including significant time as a product-facing IC.
- Proven track record of partnering with Product and Engineering to shape roadmaps, define success metrics, and drive decisions through data.
- Demonstrated ability to operate with high ownership and autonomy, including scoping ambiguous problems and driving them to closure.
- Comfort working across time zones and with distributed teams, using strong async communication and documentation habits.
Preferred Qualifications
- Graduate or PhD degree in a quantitative field (e.g., Statistics, Computer Science, Economics, Physics) or equivalent practical experience with 10+ years of experience in related fields.
- Prior experience in ad tech, marketing science, or related domains where creatives, auctions, or optimization systems are central to performance.
- Hands-on experience with creative analytics (e.g., format benchmarking, asset-level performance analysis, interaction or engagement modeling).
- Experience collaborating closely with ML teams to design, evaluate, and iterate on model features and policies.
- Excellent communication skills: ability to synthesize complex analytical findings into simple, actionable narratives for technical and non-technical audiences.
Compensation & Benefits
U.S.-based employees have access to medical, dental, and vision insurance, a 401(k) plan with company match, short-term and long-term disability coverage, basic life insurance, and well-being benefits and perks. U.S.-based employees also receive up to 12 scheduled paid holidays per calendar year and one Thrive Day off per quarter. Additionally, all employees have Flexible Time Off (FTO).
The successful candidate may be eligible for a bonus and equity awards. Eligibility and amounts are determined by performance and the terms of the applicable plans.
The location for this role is listed above. For base pay range purposes, location-based compensation is grouped into the following regions. Your region is determined by your assigned work location.
- Region A: Menlo Park Office, New York Office, SF Bay Area, New York Metro Area
- Region B: Seattle Office, Seattle, Los Angeles/Orange County, San Diego, Austin, Boston, Washington DC Metro Area, Miami
- Region C: All other U.S. locations
