iOS Engineer, AI

Polymarket•New York, NY

About The Position

Polymarket is looking for an AI-native Mobile Engineer to build the automation layer that powers our iOS development team. This is not a traditional mobile product engineering role – you’ll design and implement AI-driven systems that make our mobile engineers dramatically more efficient. You’ll work at the intersection of mobile development and AI tooling, building orchestration systems that automate everything from ticket creation to code generation, testing, and review. The goal is to push toward a fully autonomous mobile development pipeline. This is a high-ownership role for someone who is deeply curious about the frontier of AI-assisted engineering and wants to rethink how mobile software gets built.

Requirements

2+ years of experience building native iOS applications
Proficiency in Swift, with a solid understanding of mobile build systems and tooling
Strong programming skills in TypeScript (or willingness to ramp quickly)
Experience building or experimenting with AI-powered developer tools, agents, or automation systems
Familiarity with LLMs and modern AI tooling (e.g., code generation, agents, orchestration frameworks)
A systems mindset — you think in terms of pipelines, automation, and leverage
High agency and curiosity — you proactively explore new tools, ideas, and approaches

Nice To Haves

Experience building internal developer tools or CI/CD systems
Familiarity with mobile CI environments (e.g., macOS build systems, simulators, provisioning)
Experience with tools like Cursor, Claude, or similar AI coding assistant
Active engagement with the AI engineering ecosystem (Twitter, blogs, open-source, etc.)
Experience integrating with tools like Slack, Linear, or Figma APIs

Responsibilities

Build AI-powered development workflows. You’ll design and implement systems that automate the mobile development lifecycle, from issue creation to pull requests and code review.
Own mobile-specific AI tooling. You’ll tackle challenges unique to mobile environments (e.g., compilation constraints, CI on macOS, simulator workflows) and build systems that integrate seamlessly with them.
Improve the feedback loop. You’ll optimize and re-architect our current tooling stack (e.g., Slack bots, ticketing systems, codegen tools, CI pipelines) to reduce latency and increase reliability.
Develop orchestration systems. You’ll connect tools like LLMs, design systems, and codebases into cohesive pipelines that can reason about and modify mobile codebases.
Collaborate with mobile engineers. You’ll work closely with the iOS team to identify bottlenecks and build tools that meaningfully improve developer velocity.
Experiment aggressively. You’ll stay on the cutting edge of AI tooling and continuously evaluate new models, frameworks, and approaches.
Contribute to mobile code when needed. During high-priority moments, you may occasionally jump into the codebase to support product development.
