Fraud Engineer

Kalshi is the first and only federally regulated exchange where people can trade on any event. Think like the NYSE, but instead of trading stocks, you trade on the events you know and care about. Kalshi has more than 500 markets across politics, economics, financials, weather, tech, AI, culture and more.

After three years of regulatory struggle, Kalshi's historic regulatory approval from the CFTC has allowed it to launch a new asset class: event contracts. Event contracts, the fastest-growing asset class today, are elegant financial instruments structured as simple yes/no questions about the future.

Kalshi's vision is to build the next-generation financial ecosystem for trading what we believe will be the largest asset class of all. Kalshi's vision is bold. We're on a long journey in uncharted territories. We are looking for passionate and outlier members excited to embark on this voyage toward building the financial system's next inflection point.

We are building a next-generation financial ecosystem (think NYSE or CME from scratch). As part of Kalshi, you will work on various platforms, including core exchange, clearinghouse, API infrastructure, connectivity to brokers and market makers, and others. We are a small team, which means your responsibilities scale very rapidly, and your contributions are clear and visible, not marginal. There is still a lot of green field at Kalshi and a low of it (including entire systems) can be yours.

Some of the things you'll be building and working on:

• Design and build systems for financial fraud detection and remediation while balancing fraud loss, cost of implementation, and customer experience
• Work closely with finance, security, product, compliance and operations to holistically combat fraudulent and abusive actors on our system
• Stay abreast of the latest techniques and tools to stay several steps ahead of determined and well resourced adversaries
• Ship fast and with high quality.

The company is growing fast, which means your role will evolve and grow with the company. Joining Kalshi means you’ll be exposed to all parts of the business and define our culture and product paths.

• 4+ years of software engineering experience in backend and data systems
• Have at least 2 years experience in payment fraud, abuse analysis and investigations
• Can dive into our codebase, intuit how it works, and be able to have a strong intuition for suggestions that will lead us to a stronger engineering position.
• A voracious and intrinsic desire to learn and fill in missing skills. An equally strong talent for sharing that information clearly and concisely with others
• Are comfortable with ambiguity and rapidly changing conditions. You view changes as an opportunity to add structure and order when necessary

Bonus points

• Experience building financial systems, clearing infrastructure, broker connectivity, etc.
• Proven experience building large-scale systems and machine learning.
• Like to interact directly with customers.

Salary Range: $100,000 to $200,000 annually plus equity and benefits.

This salary range is based on the current available market data and represents the expected salary range for this role. Kalshi has minimal hierarchy and few titles, but a broad range of experience is represented within roles. Should you have compensation expectations that exceed these bands, we'd love to hear from you and would welcome you to reach out to discuss further.

We are a group of people who work hard and get stuff done. Meritocracy is at our core, and we value people who take ownership and figure (usually hard) things out. We dream big and climb the steeper mountain. We love our craft deeply and are proud of what we put out in the world. We are committed to our vision of an improved financial ecosystem and our mission of bringing more truth to the world through the power of markets.

Kalshians are, by far, Kalshi's largest asset: we pick our teammates carefully, but once we pick our teammates, we trust them deeply.
