The Crown Is Yours

As a Lead Software Engineer on the Performance Engineering Team, you’ll set the strategic and technical direction that ensures our systems are resilient, performant, and ready for the most high-stakes moments in sports and gaming. Part of the Systems Governance and Architecture organization, this team is responsible for system-wide performance and chaos engineering at scale. You’ll lead efforts to simulate real-world load patterns, introduce ML-powered analysis, and proactively surface risks before they impact our users.
This is a high-impact, cross-functional engineering leadership role.

What You'll Do

• Lead the design and execution of performance and chaos testing strategies for distributed, event-driven systems.

• Own the development of scalable testing frameworks and internal tools for automated KPI validation and telemetry correlation.

• Lead by example, writing high-performance, well-tested code that meets our rigorous standards for reliability and scalability.

• Lead observability and telemetry initiatives, ensuring insights are actionable and performance-focused.

• Design and implement predictive load models to prepare for high-traffic events tied to product, infrastructure, or marketing milestones.

• Collaborate cross-functionally with Product, Design, and Engineering teams to align technical solutions with strategic business goals.

• Act as a technical mentor and coach, providing guidance and feedback that helps engineers grow and deliver their best work.

• Play a critical role in shaping the team’s roadmap and technical direction while fostering a strong engineering culture grounded in ownership and continuous learning.

What You'll Bring

• Bachelor's degree in Computer Science or any suitable combination of education, experience, and training.

• At least 5 years of experience in object-oriented backend development using languages such as C# or Java, with interest and openness to transition into Python or GO.

• Familiarity with performance/load testing tools like Locust, k6, Gatling, or JMeter.

• Deep experience developing and maintaining comprehensive automated test suites, including unit, integration, and performance tests, to ensure system resilience and scalability.

• A strong track record of mentoring engineers, leading code and design reviews, and driving high-impact technical decisions across cross-functional teams.

• A proactive mindset with a focus on continuous improvement, code quality, and driving engineering best practices across teams.
