Role Overview As a Senior Platform Engineer, you will be a key driver of our core infrastructure and developer experience. You will design and implement durable platform abstractions and partner with engineering leads to ensure our systems enable rapid innovation without compromising stability or security. This role requires a balance of deep hands-on engineering and systems thinking. You will own complex features from ideation to production, championing best-in-class platform standards and mentoring mid-level engineers while remaining deeply embedded in the codebase. On the engineering side, we are pioneering the use of AI as a code collaborator. We need engineers who have moved beyond experimentation—who actively use tools like Claude Code, Cursor, or GitHub Copilot to ship production code faster while maintaining exceptional quality. Responsibilities Implement team-level standards for AI-augmented development, utilizing prompt engineering and validation frameworks to increase velocity without sacrificing code quality. Identify and mitigate AI-generated code pitfalls, such as security vulnerabilities or over-abstraction, and assist in tracking team productivity metrics. Design, build, and maintain highly available cloud-native infrastructure, ensuring the platform scales reliably with our growing user base. Build and optimize CI/CD pipelines and developer tooling to eliminate friction in the software delivery lifecycle. Implement and maintain platform security safeguards and compliance standards to protect the integrity of the firm’s systems. Contribute to the system observability roadmap by implementing monitoring, tracing, and alerting to ensure high operational reliability. Partner with product and engineering teams to translate technical requirements into scalable platform solutions. Mentor junior and mid-level engineers, lead incident response for team-owned services, and advocate for modern engineering best practices. Experience and Skills 5 plus years of experience in platform engineering, DevOps, or backend engineering, with a track record of building scalable, cloud-native environments (AWS/Kubernetes). Strong proficiency in using AI collaborators (Claude Code, Cursor, Copilot) to ship production code and an ability to optimize personal development workflows. Ability to evaluate AI-generated code for security gaps or architectural "hallucinations" and implement rigorous testing strategies. Strong hands-on experience with IaC frameworks such as Terraform , Pulumi, or CloudFormation. High proficiency in Java and Python (Golang is a plus). You should be comfortable bridging the gap between infrastructure and application logic. Experience building mature CI/CD pipelines and working with observability tools (e.g., Prometheus, Grafana, Datadog). Proven ability to take ownership of complex projects in a fast-paced environment, balancing speed with architectural health. Strong communication skills and the ability to collaborate effectively with distributed engineering and product teams. Preferred Qualifications Experience in high-growth startup environments. Experience with financial systems, real-money transactions, or regulatory compliance. Background in building internal developer tools or CLI applications. Experience leading small project groups or "squads" within a larger team. Depending on the role, your interview and onboarding experience may include in-person components, such as onsite interviews or Launching into Better: LIVE—a multi-day cultural immersion in New York City for full-time, non-seasonal hires. These sessions are designed to build connection and bring our culture to life, though specific travel and participation requirements will be confirmed based on your role and location. Your recruiter will provide clear guidance at each stage of the process. Ready to build the future of sports betting?
