The Crown Is Yours
DraftKings is growing quickly and we're looking for a Senior Lead Software Engineer to direct our engineering teams and influence our product roadmap. This is more than a technical position, though. You'll be collaborating across teams, informing our business decisions, and creatively finding solutions to all of our scaling challenges.
What you'll do as a Senior Lead Software Engineer, AI Engineering

• Take ownership of the design, development, and operations of core AI platform components-ranging from LLM runtime services to vector stores and evaluation harnesses.
• Guide your team and partner teams in building secure, scalable APIs and cloud-native services using Python, Go, or C#, and AWS infrastructure.
• Be the first voice for engineering on the systems your team owns-balancing reliability, cost, velocity, and safety.
• Lead design sessions and architecture reviews, ensuring high engineering quality, long-term maintainability, and platform consistency.
• Champion data-driven decision-making: use metrics to prioritize, de-risk, and continuously improve team throughput and platform efficiency.
• Help build a culture of technical excellence, ownership, and continuous improvement.

What you'll bring

• 6+ years of experience building distributed systems, APIs, or backend platforms in cloud-native environments.
• Strong proficiency in at least one backend language (e.g., Python, Go, C#, or Java) and experience with infrastructure-as-code (Terraform, CDK, etc.).
• Familiarity with production-grade AI systems: LLM orchestration, vector databases, embedding models, or safety layers.
• Solid understanding of performance optimization, structured logging, and cost governance in AI or platform contexts.
• Comfort designing systems from scratch as well as iterating on legacy code and architecture.
• Bias for action, ownership mindset, and a collaborative approach to solving ambiguous problems.
• Bonus: contributions to open-source projects in the AI space.
