Senior Solutions Engineer (In-App)

Join Kargo as a Senior Solutions Engineer, where you'll be the technical face of the company to app developers and publishers. In this hands-on role, you'll onboard strategic publishers, own flagship integrations, diagnose and resolve roadblocks, and architect strategies to raise eCPM/ARPDAU. You'll also establish integration patterns, partner with various teams, and feed integration friction back into the SDK roadmap. The ideal candidate will have excellent communication skills, proficiency in a production language, experience building RESTful APIs, and a strong understanding of database design and cloud infrastructure.

• Onboard and take live strategic publishers, moving each from signed to first impression to full-scale rollout ahead of target integration timelines.
• Own flagship publisher integrations end to end, from technical scoping through production launch and post-launch monetization tuning.
• Diagnose and resolve the top roadblocks capping in-app impression growth—mediation/bidding misconfiguration, low fill, latency, rendering failures—to drive measurable lifts in live impressions and fill.

• Excellent communication skills, able to explain complex technical concepts clearly to non-technical stakeholders and share knowledge generously
• Proficiency with Git, CI/CD pipelines, automated testing, and monitoring/observability tooling, with the ability to debug production issues and optimize system performance
• Expert-level proficiency in a production language such as Python, Java, Go, or JavaScript/TypeScript, with a strong grasp of data structures, algorithms, and software design patterns
• Experience building RESTful APIs and microservices, and designing scalable, distributed systems that handle high-volume traffic
• Understanding of database design and optimization across SQL and NoSQL, plus cloud infrastructure (AWS, GCP, or Azure) and containerization (Docker, Kubernetes)
• Strong ownership and technical judgment—you see projects through, make pragmatic engineering decisions, and address technical debt strategically
• Resilience and a bias for action, staying effective under pressure and breaking large problems into incremental, shippable deliverables
