Own technical decisions for platform areas that require balancing correctness, reliability, performance, and ease of adoption.
Improve the trustworthiness of experimentation by strengthening system design, observability, data quality, and operational standards.
Partner closely with engineers, data scientists, statisticians, and stakeholders to turn ambiguous requirements into scalable platform capabilities.
Mentor other engineers through design discussions, code reviews, and pragmatic technical leadership.
Minimum Qualifications
5+ years of professional software engineering experience in a production environment.
Strong hands-on experience in backend systems, data infrastructure, distributed systems, or other relevant platform areas.
Proven ability to independently drive technical projects from problem definition through production rollout in ambiguous problem spaces.
Strong engineering judgment in system design, operational reliability, maintainability, and cross-functional execution.
Bachelor's degree in Computer Science, Computer Engineering, or equivalent practical experience.
Preferred Qualifications
Experience designing and implementing experimentation platforms, A/B testing systems, feature flagging systems, or dynamic configuration platforms.
Experience owning platform or infrastructure systems used by multiple engineering teams.
Experience working with analytical data systems, metrics pipelines, or data quality and correctness challenges.
Familiarity with advertising, mobile product ecosystems, or performance-driven product environments.
