Senior iOS Engineer

Overview

We’re seeking an iOS Engineer with deep expertise in mobile 3D applications and spatial computing. You will own end-to-end delivery of major iOS features, driving our product from development to production-ready solutions. This role demands mastery of iOS development, the ability to cut through ambiguity, and ownership of complex systems in a fast-moving environment.

This is a hybrid position, meaning that you will need to live within easy driving distance to our Technology Center in Columbia, Maryland.

What You’ll Do

Feature Development & Architecture

· Own end-to-end delivery of major iOS features, taking Quidient’s 5D product and SDK from prototype to production with a focus on reliability and performance.

· Architect and design new capabilities within existing iOS codebases, establishing patterns that scale as our product line grows.

· Drive technical decisions on how Quidient builds SDKs and apps from internal frameworks, developing long term sustainable solutions that mature over time.

· Build and optimize 5D mobile applications leveraging ARKit, RealityKit, Metal, and GPU acceleration for high-performance, low-latency experiences.

· Collaborate cross functionally with SDET, Algorithm, and Infrastructure teams to harden features for production and integrate CI/CD pipelines.

· Design and implement RESTful APIs and integrate with server side technologies to support mobile backend communication.

· Assemble complex solutions from loosely defined requirements, navigating ambiguity.

· Mentor and influence technical direction across the iOS team as the product scales.

What You Bring

Must Have Qualifications:

· Bachelor’s degree in Computer Science or related engineering field.

· 7 years of industry experience in iOS development; freelance acceptable but must include experience with large, complex codebases (not simple sandbox or siloed apps).

· 3 years of experience building 3D applications or working with spatial computing technologies.

· Deep expertise in iPhone app development using Swift, with recent hands-on iOS.

· Heavy iOS framework experience including ARKit, AVFoundation, Core Location, Core Motion, VisionKit, RealityKit, ImageIO, and CoreML.

· Experience developing web based applications using modern front end technologies and server-side technologies.

· Strong experience in RESTful API design and development.

· Experience in coding languages such as C and Python.

· Demonstrated ability to assemble complex solutions from loosely defined requirements without clear PRDs or design documentation.

· Ownership mindset with ability to drive initiatives on a small team with minimal oversight.

· Live within easy commuting distance of our Technology Center in Columbia, Maryland.

· This position is not eligible for H-1B sponsorship.

· Meet Quidient, customer, and government security requirements, which may include, but are not limited to a background check, citizenship verification, and Criminal Justice Information Services verification.

Nice-to-Have Qualifications:

· Experience deploying high-performance, low-latency applications.

· Experience creating computer vision or image processing applications.

· Metal and GPU programming experience.

· Knowledge of Android app development (Kotlin) or cross-platform frameworks (Flutter).

· Knowledge of cloud products and platforms, microservice architectures, automation, and API integration.
