What is a backend developer internship?

A Backend Developer Internship is a temporary, hands-on learning opportunity for students or entry-level developers to gain experience in backend development. Interns typically work with databases, APIs, and server-side logic using languages like Python, Java, or Node.js. They collaborate with senior developers to build, optimize, and maintain backend systems. This internship helps develop technical skills, problem-solving abilities, and an understanding of industry best practices.

What are the key skills and qualifications needed to thrive in the backend developer internship position, and why are they important?

To thrive as a Backend Developer Intern, you need a foundational understanding of server-side programming languages (such as Python, Java, or Node.js), databases, and algorithms, often supported by coursework in computer science or a related field. Experience with version control systems like Git and familiarity with API development and frameworks are common technical requirements. Strong problem-solving abilities, effective communication, and a willingness to learn help interns integrate smoothly within development teams. These skills are crucial for building reliable backend services, collaborating with peers, and adapting quickly to new technologies and workplace expectations.

What kinds of projects and tasks do backend developer interns typically work on during their internship?

Backend Developer Interns often collaborate with experienced engineers to help design, develop, and maintain server-side logic, databases, and APIs. Common tasks include writing code for backend services, participating in code reviews, testing and debugging features, and assisting with database queries or schema updates. Interns may also be involved in integrating third-party services, automating system processes, and learning about best practices in software development. This hands-on experience helps interns build practical skills and gain insight into how production systems operate, preparing them for more advanced developer roles in the future.

Job description

About Polymarket
Polymarket is the world's largest prediction market platform. We enable individuals to express views on real-world events by trading on outcomes across politics, economics, sports, culture, and current affairs. Built as a peer-to-peer marketplace with no centralized "house," Polymarket aggregates diverse opinions into transparent, market-based probabilities that reflect collective expectations about the future.
We're growing fast - both in terms of volume ($21B traded in 2025) and adoption as an alternative news source. Our ambition is to become a ubiquitous beacon of truth in global media and we need your help adding fuel to the fire.
About the Role
The Markets Engineering team owns the infrastructure that keeps thousands of live markets accurate, up-to-date, and resolving correctly in real time - automation pipelines, external data integrations, and lifecycle systems that run continuously across a catalog spanning politics, sports, economics, and breaking news. When this layer works well, traders trust the platform. When it doesn't, markets go stale, resolution breaks, and confidence erodes fast.
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

Benefits
  • Competitive salary & equity
  • Unlimited PTO
  • Full Health, Vision, & Dental coverage
  • 401k match
  • Hardware setup: new MacBook Pro, big display, & accessories
