Software Engineer, Marketing

About the role

Kalshi, a prediction market platform, is hiring a Software Engineer for its Growth team in New York. You will build tools, automate workflows, ship experiments and solve the technical problems that stand between an idea and a launch, working directly with growth and marketing to turn loosely defined requests into working software. The role suits an early-career engineer who builds quickly and learns fast.

Key responsibilities

• 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 fix 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 speed development while keeping code quality, testing and reliability in hand.
• Clarify requests with teammates, prioritize competing needs and communicate progress.
• Translate spontaneous business needs into verifiable technical solutions with a short turnaround.
• Own projects from initial request through launch, monitoring and iteration.

Required profile

• Bachelor's degree (or foreign equivalent) in Computer Science, Software Engineering or a closely related field, plus 2 years of experience on production systems.
• Ability to learn new tools, frameworks and processes quickly and hands-on.
• Resourceful problem solver who acts independently and asks good questions when requirements are incomplete.
• Strong follow-through, attention to detail and comfort handling several requests at once.
• Hands-on experience with AI coding tools, with the judgment to debug and improve what they produce.
• New graduates and engineers in the first few years of their career are encouraged to apply.

Required skills

• Production code in Python, Go (Golang) or JavaScript; some mobile development with Flutter is a plus.
• Relational and NoSQL databases such as PostgreSQL, MySQL and MongoDB, including schema design, query optimization and data modeling.
• APIs, databases and version control.
• Bonus points: a launched product or side project, marketing technology or experimentation tools, advertising or automation experience, and interest in prediction markets, finance or consumer technology.

What we offer

• Salary range of 115,000 and up annually, plus equity and benefits.
• A flat, meritocratic culture with minimal hierarchy.
