Senior iOS Engineer

Role Description

Onfleet is hiring a Senior iOS Engineer based in Latin America or Canada to join our remotely distributed mobile team. You'll be a core contributor to our driver app and mobile SDK, working across new feature development, architectural improvements, and integration with our backend services. Your work will shape the daily experience of the couriers who complete millions of deliveries on our platform.

The codebase is modern Swift: unidirectional data flow (a custom Redux-style architecture), Swift concurrency, Combine, and a UIKit codebase with SwiftUI adoption underway. You'll be creating high-quality, well-tested code, contributing to a healthy Scrum cadence, and helping tame legacy complexity by putting code under test, isolating change boundaries, and simplifying tangled implementations.

If you have strong Computer Science fundamentals, deep iOS expertise, care deeply about quality and craft, and bring a scrutinizing, questioning mindset, we'd love to hear from you.

Qualifications

• Bachelor's degree in Computer Science or a related field, and strong CS fundamentals: data structures, API design, testing, and an instinct for clean, maintainable code.
• Proven production delivery. You have shipped iOS apps to the App Store on a team that operated them in production, and you've personally owned features through release and into production support.
• Excellent written and spoken English. You can work entirely in English on a distributed team, explain complex technical ideas clearly, and write docs and code reviews your teammates rely on. This is roughly equivalent to a C1 level of English.
• 6 or more years of hands-on professional software engineering experience, with at least 5 years focused on iOS.
• Deep Swift expertise including protocol-oriented programming.
• Production experience with UIKit and unidirectional data-flow architectures (The Composable Architecture, Redux, ReSwift, or similar).
• Solid command of Swift concurrency (async/await, AsyncSequence) and Combine for UI, data, and concurrency.
• A demonstrated quality focus beyond "writing tests." You have, for example, created, configured, fine-tuned, or troubleshooted a CI/CD pipeline for iOS (GitHub Actions, Bitrise, or equivalent), not just consumed one someone else built.
• Hands-on experience writing both unit and integration/regression tests as part of how you build.
• Experience with creating software using disciplined agentic flows, from prompt-instructing to complete development orchestrations.
• A scrutinizing, questioning mindset: you don't accept output, your own or an agent's, at face value, and you surface problems early.
• Sound judgment, a pragmatic approach, and an open mind to help guide the team when the path forward is unclear.

Requirements

• Experience with a UIKit to SwiftUI migration in production.
• Modular iOS development with Swift Package Manager, and experience creating prebuilt/binary library solutions.
• Local persistence, offline-first and background data processing experience.
• Test-Driven Development (TDD) experience.
• Prior QA, SDET, or test-engineering experience, or a verifiable track record of owning testing/quality on a team.
• Android, cross-platform or server development experience.

Benefits

• This is a remote role open to candidates based only in Latin America or Canada.
• Onfleet offers flexible work arrangements; you can work from home or anywhere with a reliable internet connection.
• The team is distributed across the Americas and Europe. Your working hours need to include at least 4 hours of overlap with US Pacific business hours (roughly 9am–1pm PST / 1–5pm in most of Latin America).
• Flexible PTO.
• Laptop and WFH Stipend.
• Technology Monthly Stipend (internet/AI).

Compensation

The base salary range for this role is $75,000 to $115,000 USD per year, depending on experience, skills, and background. Where an offer lands within that range reflects the engineering level, and the depth and experience a candidate brings to the role.

How we hire

You need an identity-verified LinkedIn profile to apply. That's the free "Verified" badge, the shield icon next to your name. We check for it, and applications without it don't move forward.

Before any offer, we verify your identity and work history. That includes a live video ID check and reference calls. We use AI, automated systems, and a person to review applications: every application that meets the requirements is also read by an engineering leader or a recruiter. If you misrepresent your identity or experience, the process ends.
