Software Engineer II - Moloco Commerce Media (소프트웨어 엔지니어)

About the role

As a Software Engineer on the MCM(Moloco Commerce Media) team, you will build and evolve backend systems, experimentation capabilities, and product workflows that power Moloco Commerce Media’s retail media platform.

Your work will directly shape how retailers, advertisers, and internal teams launch, scale, measure, and improve commerce media products and monetization strategies. You will help deliver reliable, scalable, and data-informed solutions across campaign and bidding workflows, pricing and pacing logic, experimentation, and platform integrations, driving meaningful customer and business impact.

Here’s what you’ll be working on:

• Design, implement, and operate backend services, APIs, and internal systems that support core MCM workflows across campaign delivery, bidding, auction, pricing, experimentation, and product launch operations.
• Own features or projects end-to-end, from problem framing and requirements review through technical design, implementation, testing, launch, and post-launch iteration.
• Partner closely with Product, Data Science, ML, Customer Engineering, and business stakeholders to translate complex retailer and advertiser needs into simple, reliable, and scalable platform capabilities.
• Contribute to experimentation and launch infrastructure that enables teams to validate improvements, roll out new capabilities safely, and make data-driven product decisions.
• Improve the reliability, performance, and observability of the systems you build through strong engineering practices, including testing, metrics, logging, monitoring, and incident response.
• Contribute to integrations and platform capabilities needed to support global expansion, customer-specific requirements, and evolving commerce media product needs.
• Contribute to raising the team’s engineering bar and support a collaborative culture of technical excellence and continuous improvement.

Basic Qualifications

• BS/MS in Computer Science or a related technical field, or equivalent practical experience.
• 4+ years of software engineering experience in backend or full-stack development.
• Proficiency in at least one modern programming language such as Java, Go, C++, or Python.
• Solid understanding of data structures, algorithms, and system design, with hands-on experience building or maintaining distributed systems and web services / APIs.
• Experience working with relational or NoSQL databases and large-scale production systems.
• Experience owning features or components end-to-end under guidance from more senior engineers.
• Ability to collaborate effectively in a cross-functional environment with Product, Data Science, ML, Customer Engineering, and other engineering teams.
• Fluent verbal and written communication skills in English; ability to discuss designs, trade-offs, and timelines with global stakeholders.

Preferred Qualifications

• Experience building backend systems for advertising, e-commerce, marketplace, retail media, or other high-scale product platforms.
• Experience working on experimentation, feature rollout, configuration management, or decisioning systems in production environments.
• Experience with bidding, pricing, recommendation, attribution, or other optimization-related product areas.
• Familiarity with cloud platforms and data technologies such as GCP, BigQuery, Bigtable, Kafka, Beam/Spark, or similar tools used in large-scale data and product systems.
• Experience integrating product requirements, customer feedback, and operational constraints into scalable engineering solutions.
• Interest in or demonstrated ability to improve reliability, observability, testing, and overall engineering quality in production environments.
• Experience supporting customer-facing or business-critical systems where launch quality, operational excellence, and iteration speed matter.
• Prior experience in global or multi-region environments where product requirements, regulations, or market needs differ across customers and regions is a plus.
