Lead Engineer

At FanDuel, we don't just write code — we engineer the pulse of sport. Every NFL touchdown, NBA buzzer-beater, and MLB walk-off home run is backed by the platforms our teams build, scale, and evolve in real time. Millions of fans engage with our products every single day — and you'll help make that experience faster, smarter, and more thrilling.

We're part of the FanDuel Group, the premier mobile gaming company in North America and a proud member of Flutter Entertainment — the world's largest sports betting and gaming operator. From Melbourne to New York, Edinburgh to Dublin, our engineers collaborate across continents to craft experiences that connect sports fans everywhere.

Now, we're looking for a Lead Engineer (.NET) to join our Sportsbook engineering group — a team of curious, pragmatic builders shaping the future of sports technology.

Our Commitment

We're proud to lead the way in Responsible Gambling, setting global standards for player wellbeing and trust.

And we're equally proud to build an environment where everyone can thrive — across borders, backgrounds, and life stages.

If you need adjustments during the recruitment process or flexibility in how you work, we've got you covered.

What you'll be doing

You'll design, build, and scale the distributed systems that power our global sportsbook — the real-time engine behind thousands of live betting markets across the NFL, NBA, MLB, and beyond.

You'll:

• Lead architecture and design for scalable, cloud-native systems built in .NET Core and C#
• Build resilient, event-driven systems using Kafka, RabbitMQ, or AWS EventBridge
• Deploy and orchestrate infrastructure using Kubernetes and Terraform
• Drive CI/CD excellence through Buildkite pipelines
• Partner with engineering and product leaders across global teams to shape technical strategy
• Champion operational excellence, observability, and fault-tolerance in AWS
• Mentor engineers, elevate standards, and help shape our engineering culture
• Collaborate with teams from Australia, the US, the UK, and Ireland to deliver the next evolution of sportsbook performance

What we're looking for

You're a technical leader who thrives on building for scale and mentoring others to do the same.

You'll bring:

• Deep experience in .NET Core, C#, and modern cloud architecture
• Proficiency with Kubernetes, Terraform, and Buildkite
• Experience designing event-driven, high-throughput, and fault-tolerant systems
• Strong understanding of AWS, CI/CD, and infrastructure-as-code principles
• Knowledge of concurrency, multi-threading, and low-latency programming
• The ability to communicate clearly and collaborate across teams and time zones
• A love of product-driven engineering — building for performance, reliability, and the fan experience

Why FanDuel?

This is where sports and software collide. You'll be solving real-world problems at the intersection of scale, data, and entertainment — working on systems that keep pace with live games, dynamic odds, and millions of passionate users.

You'll get:

• 25 days annual leave (five full weeks to recharge)
• $1050 work-from-home allowance
• Tailored career development programs and leadership pathways
• Global exposure — work with engineers from New York to Glasgow
• AWS certifications, hack days, and innovation sprints
• Internal Women in Tech community and DEIB networks

• Generous parental leave and Circle In membership for family support
• True flexibility to work how and where you do your best work
