Overview
As a Lead iOS Engineer at Freshworks, you own the technical direction of one or more flagship mobile applications serving millions of users. You set the architectural standard, make build-vs-buy and native-vs-cross-platform calls, and are accountable for the quality, performance, and release health of your surface area. You lead a team of iOS and cross-platform engineers through design reviews, mentorship, and hands-on pairing, and you partner directly with Product, Design, Backend, and QA leadership to shape the roadmap. You remain a hands-on engineer: you write code in the hardest parts of the system, and your judgement is the escalation point when the team is stuck.
Technical Leadership and Architecture
- •Own and evolve the mobile architecture across the app portfolio including modularization, dependency boundaries, state management, navigation, and offline/sync strategy.
- •Make and document consequential technical decisions (native Swift vs Flutter/React Native, third-party SDK adoption, persistence and caching strategy) with clear trade-off analysis and a migration path.
- •Author and drive technical design documents; run design reviews and hold the bar on SOLID, clean architecture, and pattern consistency (MVVM, VIPER, Coordinator, unidirectional data flow).
- •Lead large-scale refactors and platform migrations (e.g. UIKit to SwiftUI, monolith to modular packages) with incremental, low-risk rollout plans.
- •Identify and remove systemic technical debt; maintain a prioritized architecture backlog reviewed with Product and Engineering Management.
Delivery and Execution
- •Break down ambiguous, multi-quarter product initiatives into scoped, sequenced, estimable work for the team.
- •Stay hands-on: personally deliver the highest-risk components, prototypes, and performance-critical paths.
- •Own the release train including versioning, release branching, phased rollouts, App Store submission and review escalations, kill switches, and rollback procedures.
- •Own build and developer productivity: build times, flaky test elimination, local dev setup, and CI/CD reliability (Fastlane, GitHub Actions).
- •Drive integration contracts with backend teams for RESTful and GraphQL APIs, including versioning, backward compatibility, and error-handling standards.
Quality, Performance, and Reliability
- •Define and enforce the quality bar: test strategy across unit, integration, snapshot, and UI layers; code coverage expectations; and mandatory quality gates in CI.
- •Own crash-free-session rate, ANR/hang rate, cold-start and frame-rate budgets, app size, and battery/network efficiency; set targets and report against them.
- •Instrument and profile with Instruments, MetricKit, and Xcode Organizer; lead performance investigations that cross app, SDK, and backend boundaries.
- •Act as incident commander for production mobile incidents: triage, mitigate, communicate, and run blameless post-mortems with tracked action items.
- •Define observability standards: crash reporting, structured logging, analytics events, feature flags, and remote config (Crashlytics/Sentry, Firebase Remote Config).
People and Influence
- •Mentor senior, mid-level, and junior engineers; grow at least one engineer to the next level through structured feedback and stretch ownership.
- •Own code review culture: set expectations for review depth and turnaround, and coach through reviews rather than gatekeeping.
- •Drive the hiring bar for mobile: design and calibrate interview loops, conduct architecture and coding interviews, and support onboarding.
- •Provide input to Engineering Managers on performance, growth, and team composition.
- •Represent mobile engineering in cross-functional and cross-org forums; influence platform, design-system, and API decisions made outside your team.
- •Write and evangelize internal standards, playbooks, and documentation; run knowledge-sharing sessions and guild forums.
Product and Business Partnership
- •Partner with Product to shape scope and sequencing: surface technical constraints early and propose cheaper paths to the same outcome.
- •Define success metrics with Product (adoption, engagement, crash rate, task completion) and drive iteration based on data.
- •Assess feasibility and effort for new initiatives; provide credible estimates with explicit assumptions and risks.
- •Implement and support compliance with Freshworks security processes including secure-coding practices, data-handling requirements, and privacy/App Store policy obligations.
Requirements
- •8+ years of professional software engineering experience, with 6+ years building and shipping production iOS applications.
- •2+ years in a technical leadership role owning architecture and outcomes for a team of engineers.
- •Expert-level Swift with strong Objective-C interop; deep command of the iOS SDK, Xcode, Instruments, and the full debugging toolchain.
- •Demonstrated ownership of a non-trivial mobile architecture at scale, including modularization and dependency management (SPM/CocoaPods).
- •Deep expertise in concurrency and multithreading (GCD, Swift Concurrency/async-await, actors), memory management, and race/deadlock diagnosis.
- •Strong experience with UIKit and SwiftUI, plus reactive/asynchronous patterns (Combine or equivalent).
- •Proven experience with cross-platform delivery (Flutter or React Native) and the judgement to know when not to use it.
- •Data persistence and offline-first design (Core Data, SQLite, Realm) including migrations and conflict resolution.
- •Ownership of mobile CI/CD end to end (Fastlane, GitHub Actions), code signing, provisioning, and App Store Connect release operations.
- •Track record of driving measurable improvements in app performance, stability, or engineering velocity.
- •Strong grounding in OOP, design patterns, SOLID, data structures, and algorithms.
- •Strong written communication: design docs, RFCs, and post-mortems.
- •Demonstrated ability to mentor engineers and build consensus across teams without formal authority.
- •Extensive experience with Agile methodologies and strong working knowledge of the SDLC.
Nice to Have
- •Experience leading a UIKit to SwiftUI or native to cross-platform migration in production.
- •Mobile security depth: Keychain, certificate pinning, encryption at rest, jailbreak/tamper detection, OWASP MASVS familiarity.
- •Experience building and maintaining shared SDKs, internal libraries, or a design system consumed by multiple apps.
- •Experience with GraphQL on mobile, including caching and schema evolution.
- •Experience with experimentation platforms, feature flagging, and progressive delivery at scale.
- •Familiarity with Android/Kotlin sufficient to reason about parity and shared architecture decisions.
- •Experience in B2B SaaS, multi-tenant, or enterprise mobility (MDM, SSO/SAML, on-prem constraints).
- •Accessibility (VoiceOver, Dynamic Type) and internationalization at scale.
- •Open-source contributions, conference talks, or active participation in iOS developer communities.
