Role

We are looking for a Mac/iOS Developer based in San Jose, CA (Hybrid), reporting to the Sr. Manager of Software Engineering in the Endpoint Engineering department. You will be a key driver on the Mobile team, developing cross-platform client applications for MacOS and iOS that securely steer traffic to the world's largest cloud security platform. Your vision and technical expertise will enable organizations worldwide to harness speed and agility through a cloud-first strategy, directly impacting a global footprint of over 65 million users.

What you'll do (Role Expectations)

Develop high-performance MAC and iOS applications and frameworks that serve as the gateway to our global cloud security platform.

Partner with product managers to translate complex requirements and design mockups into clean, high-quality code.

Take accountability for the performance, quality, and responsiveness of applications to ensure a seamless user experience.

Uphold and evolve engineering excellence by maintaining rigorous code quality, standards, and automation practices.

Act as a technical point of escalation to troubleshoot and resolve complex customer issues with speed and precision.

Who You Are (Success Profile)

You thrive in ambiguity. Youre comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful.

You act like an owner. Your passion for the mission fuels your bias for action. You operate with integrity because you genuinely care about the outcome. True ownership involves leveraging dynamic range: the ability to navigate seamlessly between high-level strategy and hands-on execution.

You are a problem-solver. You love running towards the challenges because you are laser-focused on finding the solution, knowing that solving the hard problems delivers the biggest impact.

You are a high-trust collaborator. You are ambitious for the team, not just yourself. You embrace our challenge culture by giving and receiving ongoing feedback-knowing that candor delivered with clarity and respect is the truest form of teamwork and the fastest way to earn trust.

You are a learner. You have a true growth mindset and are obsessed with your own development, actively seeking feedback to become a better partner and a stronger teammate. You love what you do and you do it with purpose.

What We're Looking for (Minimum Qualifications)

4+ years of professional software development experience specializing in Objective C, SWIFT, or C++.

Deep technical understanding of the Mac networking stack, networking protocols, and modern architectural design patterns.

Proven experience working with RESTful APIs, offline storage, multi-threading, and performance tuning.

Extensive knowledge of the Mac/iOS ecosystem and the standard libraries used for common engineering tasks.

Demonstrated ability to translate product requirements into high-quality, scalable technical solutions.

What Will Make You Stand Out (Preferred Qualifications)

Specialized experience in network stack development specifically for VPN or ZTNA client applications.

Professional familiarity with PKI, network security technologies, cloud message APIs, or Apple Push Notifications.

A proven track record of navigating the unique intricacies and challenges of building multi-platform client applications.
