Confirmed on the employer's own hiring board on Nov 10, 2026. First seen by Alion on Nov 10, 2026. Kalshi scores A on the Alion truth index.
What is Kalshi?
Kalshi has defined a new category: prediction markets. Kalshi allows people to trade on the outcome of any events and turn any question about the future into a financial asset. Kalshi fought for years and legalized prediction markets in the US for the first time in history, is currently the fastest growing financial market in America, and has thousands of markets across politics, economics, financials, weather, tech, AI, culture and more.
We believe prediction markets have the potential to be the largest financial market because they turn anything into a financial position.
Our vision: well… build the largest financial market on the planet.
Our mission: bring more truth to the world through the power of markets.
Our culture is simple: we hire really talented people, work really hard, and enjoy the climb. We are looking for ambitious and exceptional people to join our (relatively small) team to help us build the next generation of financial markets.
ROLE ROADMAP
We’re looking for a Software Engineer to help Kalshi’s Growth team move faster. You’ll build tools, automate workflows, ship experiments, and solve the technical problems that stand between an idea and a launch.
You’ll work directly with growth and marketing to turn loosely defined requests into working software. Some days you’ll build something new. Other days you’ll debug an integration, fix a broken workflow, or ship a small improvement that saves the team hours. You’ll own the details and follow through until the work is live and working.
This is an opportunity for an exceptional and fast-moving early-career engineer who loves building and learns quickly. We’re scaling fast, and your scope will grow as you demonstrate what you can own.
WHAT YOU’LL DO
Build and maintain tools, integrations, and automations that help the Growth team execute faster.
Turn growth and marketing ideas into working prototypes, experiments, and production tools.
Troubleshoot broken workflows and integrations, resolve urgent issues, and address recurring problems at the source.
Connect APIs and data sources to reduce manual work and make existing tools work better together.
Use AI coding tools to accelerate development while taking responsibility for code quality, testing, and reliability.
Work directly with teammates to clarify requests, prioritize competing needs, and communicate progress.
Translate spontaneous business needs into verifiable technical solutions, with a short turnaround time.
Own projects from initial request through launch, monitoring, and iteration.
WHAT YOU BRING
Must have a Bachelor’s Degree (or foreign equivalent) in Computer Science, Software Engineering, or a closely related field, plus 2 years of experience working on production systems.
Strong coding fundamentals and evidence that you can build and ship working software. Demonstrated ability developing, testing, and maintaining production software. Used languages like Python, Go (Golang), JavaScript to write polished production code. Some mobile development experience with Flutter is a plus.
Demonstrated ability working with both relational and NoSQL database systems, such as PostgreSQL, MySQL, and MongoDB, including schema design, query optimization, and data modeling.
Demonstrated knowledge of APIs, databases, version control.
Ability to learn new tools, frameworks, and processes quickly and in a hands-on, feet-first fashion.
Resourcefulness in problem-solving - knowing when/how to ask questions while primarily acting independently.
Hands-on experience using AI coding tools, with the judgment to understand, debug, and improve what they produce. Your ability to multitask here is important.
Resourcefulness when requirements are incomplete. You ask good questions, find a practical path forward, and keep moving.
Strong follow-through and attention to detail. You care whether the thing you shipped actually works.
Comfort managing several requests at once and adapting when priorities change.
Readiness to put out daily fires and respond to frequent changing requests.
Curiosity about how software can help a business reach more users and grow.
Clear communication and the ability to work independently while asking for help when needed.
New graduates and engineers in the first few years of their careers are encouraged to apply. We care about what you’ve built, how you think, and how quickly you learn.
Bonus Points:
You’ve built and launched a product, side project, or business that people actually use.
Experience with marketing technology, analytics, tracking, or experimentation tools.
Experience running online advertisements, dropshipping, sneaker botting, restaurant reservations, video game servers, etc. You have a knack for niche applications of software and care a lot about shipping fast at scale.
Experience building web applications, internal tools, or workflow automations.
Interest in prediction markets, finance, or consumer technology.
