Senior Software Engineer - iOS at Samsara

Samsara (NYSE: IOT) is the pioneer of the Connected Operations™ Cloud, which is a platform that enables organizations that depend on physical operations to harness Internet of Things (IoT) data to develop actionable insights and improve their operations. At Samsara, we are helping improve the safety, efficiency and sustainability of the physical operations that power our global economy. Representing more than 40% of global GDP, these industries are the infrastructure of our planet, including agriculture, construction, field services, transportation, and manufacturing — and we are excited to help digitally transform their operations at scale.

Working at Samsara means you’ll help define the future of physical operations and be on a team that’s shaping an exciting array of product solutions, including Video-Based Safety, Vehicle Telematics, Apps and Driver Workflows, Equipment Monitoring, and Site Visibility. As part of a recently public company, you’ll have the autonomy and support to make an impact as we build for the long term.

About the role:

The Routing organization is building one of Samsara’s most ambitious mobile experiences, designed to support the daily workflows of drivers in the field and help them stay safe, efficient, and on track. This is a deeply technical problem space that blends real-time data, thoughtful UX, and platform-wide coordination to create a seamless experience under challenging conditions, like poor connectivity, dynamic job schedules, and constantly changing routes.

We’re looking for engineers who want to work close to the customer, move fast, and shape the future of Samsara’s Driver App. You’ll join a team that values quality, performance, and impact - and you’ll help deliver a product that’s critical to the success of our customers’ operations and the safety of their teams.

This is a full-time remote position. This position requires travel up to 10% of the time and proximity to an international airport. Relocation assistance will not be provided for this role.

You should apply if:

• You want to impact the industries that run our world: Your efforts will result in real-world impact—helping to keep the lights on, get food into grocery stores, reduce emissions, and most importantly, ensure workers return home safely.

• You are the architect of your own career: If you put in the work, this role won’t be your last at Samsara. We set up our employees for success and have built a culture that encourages rapid career development, countless opportunities to experiment and master your craft in a hyper growth environment.

• You’re energized by our opportunity: The vision we have to digitize large sectors of the global economy requires your full focus and best efforts to bring forth creative, ambitious ideas for our customers.

• You want to be with the best: At Samsara, we win together, celebrate together and support each other. You will be surrounded by a high-calibre team that will encourage you to do your best. 

In this role, you will: 

• Champion, role model, and embed Samsara’s cultural principles (Focus on Customer Success, Build for the Long Term, Adopt a Growth Mindset, Be Inclusive, Win as a Team) as we scale globally and across new offices

• Design and develop advanced native iOS features and modules in Swift, tackling complex challenges such as real-time data, mapping, and sensor integrations to deliver a seamless, high-performance user experience

• Profile, analyze, and optimize app performance (CPU, memory, network), using tools like Xcode Instruments to pinpoint bottlenecks and ensure the application runs smoothly and efficiently at scale

• Architect and maintain a scalable iOS codebase with clean design patterns and best practices, ensuring solutions are built for the long term and are easy to maintain as the product evolves

• Collaborate closely with product managers, designers, and other engineers to rapidly iterate on new features with a sense of urgency, delivering incremental value to users without compromising quality or stability

• Provide technical leadership within the iOS team by setting and upholding a high bar for code quality through code reviews, mentoring junior developers, and driving continuous improvements in our development process

Minimum requirements for the role:

• 5+ years of professional iOS development experience building and shipping complex, high-quality apps (using Swift and Objective-C)

• Deep understanding of the iOS platform and SDK – expert in Swift and UIKit (including familiarity with low-level iOS APIs) and comfortable with concurrency/reactive programming patterns (e.g. Grand Central Dispatch, Combine)

• Strong experience in performance tuning and debugging on iOS, including profiling with Instruments to diagnose and fix memory, CPU, or networking issues

• Experience writing unit tests and UI tests (XCTest/XCUITest) and working with continuous integration systems to ensure robust, reliable releases

• Familiarity with iOS accessibility standards and tools (VoiceOver, Dynamic Type, etc.), with a commitment to building inclusive, accessible applications

An ideal candidate also has:

• Experience with geospatial or mapping technologies (MapKit, Mapbox, or other GIS frameworks) is a strong plus

• Familiarity with the logistics, transportation, or fleet management domain (e.g. telematics, routing, or industrial IoT applications) is beneficial

• Experience with React Native application development

• Exposure to hardware integrations on iOS (Bluetooth LE devices, cameras, or other sensors) is a bonus
