iOS Engineer

• Set technical direction for complex iOS initiatives across Bumble For Friends and Plans, translating product ambition into scalable mobile architecture that supports friendship, group, and community experiences.
• Lead the design and delivery of high-quality iOS features end-to-end, from technical design and implementation through testing, release readiness, App Store delivery, and post-launch learning.
• Champion Excellence by evolving Swift-based architecture in a large production codebase, including patterns such as MVVM, The Composable Architecture-inspired approaches, or similar, so teams can move quickly without compromising maintainability.
• Shape performant, accessible, and localised user experiences using deep knowledge of UIKit, working knowledge of SwiftUI, Swift Concurrency, view rendering, app lifecycle, memory management, and iOS platform fundamentals.
• Take ownership of reliability and performance across the iOS experience, including multithreading, networked application programming interface integrations, error handling, latency, crash diagnosis, and smooth rendering.
• Collaborate with purpose across mobile, backend, product, design, data, and safety partners to define pragmatic technical paths, resolve trade-offs, and see work through from insight to impact.
• Mentor engineers through design reviews, code reviews, architecture discussions, debugging practices, and testing strategy, creating a culture of Respect where strong technical debate leads to better outcomes.
• Stay curious about responsible AI-assisted development workflows, such as improving test coverage, documentation, debugging, and delivery quality, while applying human judgment, privacy awareness, and care to how tools are used

• Own the iOS product. Take end-to-end ownership of Polymarket's iOS experience, from technical architecture and performance to product quality and release discipline.
• Set the technical direction. Make and own architectural decisions for the iOS platform, ensuring the codebase is built to scale and maintained with rigor as the product grows.
• Build for real-time. Design and implement experiences that handle live market data, fast-moving prices, and real-time order state in a way that feels fast and reliable to users.
• Raise the engineering bar. Lead code reviews, establish strong iOS engineering standards, and help grow the capability of the broader mobile team.
• Partner across the company. Work closely with product, design, and backend teams to align on priorities, define APIs and data contracts, and ship high-quality experiences end-to-end.
• Contribute to mobile strategy. Help shape how Polymarket thinks about mobile as a platform, including architecture decisions that set up the team for scale.

Lead iOS Engineer

• Direct multiple AI coding agents in parallel to design, build, test, and ship iOS features in Swift, UIKit, and (increasingly) SwiftUI.
• Take total ownership of a slice of the iOS app — discovery, scoping, architecture, implementation, QA, release, monitoring, and iteration.
• Run an "engineer-as-a-team" workflow — spawn agents for spec drafting, codegen, test generation, code review, refactoring, doc writing, and bug triage, then merge, judge, and ship.
• Develop and defend a strong point of view on what good iOS code looks like inside Grove's architecture (View Controllers + ViewState value types, AppController/Coordinator patterns, protocol-driven Services and Data Managers, Combine, modularized via local Swift Packages) so you can critically review AI output and reject what doesn't meet our bar.
• Design prompts, evals, and harnesses that make AI-assisted mobile development repeatable and measurable, not artisanal.
• Stand up automation that closes the loop: Fastlane lanes, CircleCI checks, TestFlight distribution, device test farms, telemetry-driven rollback, and AI-powered review gates.
• Drive architecture decisions with AI as a research and prototyping partner — explore three options in a day instead of one in a week, especially during the UIKit → SwiftUI migration.
• Collaborate with other engineers on architecture and trade-offs — bring designs for review before you ship them. Solicit business context from PMs, designers, and platform engineers; don't guess in isolation.
• Own production health autonomously — monitor Sentry, Datadog, Cloudflare, and Firebase to assess system health, triage incidents, and re-prioritize your own backlog without being asked. You set the queue; you don't wait for someone to tell you what's broken.
• Mentor the Heady contractor team on AI-native workflows and share learnings with mobile peers.
