Senior Manager, Fraud

At Underdog, we make sports more fun.

Our thesis is simple: build the best product for sports fans and we will win the space. Founded in 2020, we're one of the fastest-growing sports companies ever, and there’s still so much left to do. We've built and scaled products across fantasy sports, sports betting, and prediction markets, all united in one app that’s seamless, intuitive, and actually fun to use.

Underdog isn’t for everyone. One of our core values is give a sh*t. The people who win here are the ones who care, push, and perform. We’re remote-first by design, but highly collaborative with regular in-person gatherings that help teams build, iterate, and move fast together.

Got that dog in you? Join us.

After all, winning as an Underdog is more fun.

What you'll do:

Underdog is looking for a Senior Manager, Fraud to own and grow our fraud program. This is a builder's role: you will take an evolving fraud landscape and turn it into strong, well-instrumented rules, controls, and decisioning strategies. You will work across the full fraud lifecycle, partner closely with Product, Engineering, and Data/Analytics, and drive ambiguous problems through to implementation.

This role is built around fraud expertise and judgment. Success will be measured by the strength of the fraud program you build and your ability to influence and align teams across the company.

Own and grow the fraud program - find the gaps in how we detect, decide, and investigate fraud today, then build or fix what closes them

Lead and develop a high-performing fraud team - set clear priorities, strengthen fraud judgment, and hold the team accountable for measurable outcomes

Design the decisioning strategy - build the rules, signals, and logic that carry a case from detection through mitigation and measurement

Run the tools yourself - configure and tune platforms like Sift, Sardine, or similar to sharpen detection accuracy and cut false positives

Partner directly with Product and Engineering to scope, build, and ship new fraud capabilities and controls

Work the data - spot fraud trends, test hypotheses, and prove out what your controls are actually doing, alongside Data/Analytics

Push automation forward - look for every chance to put AI, automation, and new data sources to work on fraud

Drive it across teams - take on ambiguous fraud problems and carry them through to implementation, pulling in Product, Engineering, Data, Operations, and Legal/Compliance as needed

Who you are:

You have 5+ years in fraud, risk, payments risk, or a similar function

You’ve led and developed fraud professionals, setting clear priorities, strengthening their judgment, and holding the team accountable for results

You're hands-on with fraud tooling - platforms like Sift, Sardine, or similar decisioning tools

You know the full fraud lifecycle inside and out, and can design rules, controls, signals, and decisioning strategies across it

You're fluent in data - spotting trends, forming hypotheses, and measuring performance alongside Data/Analytics

You've partnered directly with Product and Engineering to build or ship fraud capabilities

You think AI and automation first, always looking for new tools and data to apply

You can take an ambiguous problem and drive it to implementation across multiple teams

Our target starting base salary range for this position is between $140,000 and $175,000, plus target equity. Final compensation will be determined based on a variety of factors including relevant experience, skills and expertise, interview performance, and other market considerations.

What we can offer you:

Unlimited PTO for full-time employees (we're extremely flexible with the exception of the first few weeks before and into the NFL season)

16 weeks of fully paid parental leave

Home office stipend

A virtual-first culture, but we come together a few times per year in person for offsites, trainings, hackathons, and more
