Role RoadmapWe 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 lot of it (including entire systems) can be yours.
What you'll do- Design and implement high-performance backend services and APIs that enable rapid testing of new trading features and experiences as Kalshi's user-base scales
- Architect and maintain systems for personalization engines, recommendation algorithms, and other data-driven features that enhance trader engagement and retention
- Partner with product managers and frontend engineers to pilot initiatives that aim to improve or expand Kalshi's platform
What we're looking forAttributes:- Bachelor's degree in Computer Science or equivalent professional experience, with 4+ years of hands-on software development
- Strong command of key programming languages such as Golang, Java, etc.
- Strong knowledge of REST API design and development
- Experience with relational and NoSQL databases, such as PostgreSQL, MySQL, MongoDB.
- Proven track record of taking initiative and thriving in fast-paced environments
- Comfortable refining loose requirements into a clear technical spec
- Passionate about your craft and committed to delivering exceptional results
Bonus points- Experience supporting low-latency, dynamic interfaces using Websockets or similar event-based infrastructure
- Familiarity with cloud platforms like AWS, Azure, or GCP
- Experience with growth experiments or A/B testing frameworks
- History with day trading stocks, futures, or options (to better understand the experience of our members)
Our CultureMeritocracy is at our core, and we value people who take ownership and figure (usually hard) things out. We dream big. We love our craft deeply and are proud of what we put out in the world. We are committed to our vision of building something big... but also useful: a product that brings more truth through the power of markets.
Kalshians are Kalshi's most important asset: we pick Kalshians carefully, so we trust them fully on day 1.
