Job Description
We’re hiring an early-career backend engineer to join the Markets automation team and own meaningful pieces of this infrastructure from day one. You’ll work alongside senior engineers, but this is not a support role — you’ll own well-scoped pipelines end-to-end, ship to production within your first few weeks, and take on broader ownership as you grow. The problems are concrete, the feedback loops are short, and the stakes are real.
What You’ll Do
- Build and maintain automation pipelines that handle market creation, parameter configuration, and lifecycle updates across thousands of concurrent markets
- Integrate sports APIs, news feeds, and other external data sources that drive market creation and resolution, including handling the messy, inconsistent data that comes with real vendors
- Design pipelines for reliability, idempotency, safe re-runs, and fast failure detection through monitoring and alerting
- Contribute to the data-driven systems that resolve markets accurately and on time
- Debug production failures across markets infrastructure, often under time pressure, with senior support available
- Review code and participate in design discussions as a full member of the engineering team
What We’re Looking For
- 1–4 years of professional backend engineering experience, or equivalent evidence such as strong internships combined with serious personal projects
- Proficiency in TypeScript, Python, or Go — genuinely strong in at least one and able to move in the others
- Hands-on experience integrating third-party APIs and working with real-world data that is inconsistent, delayed, or poorly documented
- Evidence that you ship: a production job, public repositories with real code, or personal projects that are actually running
- Comfort with AI-native development tools such as Claude Code, Codex, or Cursor — this is part of how we work, not optional
- Ownership mindset — you want to run what you build and you care when things break
- Comfort on Linux and with cloud tooling, or a clear track record of picking up new infrastructure quickly
- (Plus) Personal projects built on Polymarket, Kalshi, or other prediction market APIs
- (Plus) Exposure to queues, streaming systems (Kafka, RabbitMQ), or workflow engines
- (Plus) Genuine interest in prediction markets, sports, or trading
Selection Process
