Assistant Unity Game Developer Jobs in California

Who we are
Gatik, the leader in autonomous middle-mile logistics, is revolutionizing the B2B supply chain with its autonomous transportation-as-a-service (ATaaS) solution and prioritizing safe, consistent deliveries while streamlining freight movement by reducing congestion. The company focuses on short-haul, B2B logistics for Fortune 500 retailers and in 2021 launched the world's first fully driverless commercial transportation service with Walmart. Gatik's Class 3-7 autonomous trucks are commercially deployed across major markets, including Texas, Arkansas, and Ontario, Canada, driving innovation in freight transportation.
The company's proprietary Level 4 autonomous technology, Gatik Carrier™, is custom-built to transport freight safely and efficiently between pick-up and drop-off locations on the middle mile. With robust capabilities in both highway and urban environments, Gatik Carrier™ serves as an all encompassing solution that integrates advanced software and hardware powering the fleet, facilitating effortless integration into customers' logistics operations.
About the role
We're looking for a Senior Software Engineer (Unity / C#) to build and scale a 3D Human Machine Interface (HMI) and its supporting content delivery pipeline for real-world autonomous vehicle systems.
At Gatik, our autonomy systems are deployed in live, commercial operations, and this role sits at the intersection of visualization, tooling, and system observability. You will be building interfaces that enable engineers and operators to monitor, debug, and understand autonomy behavior in real time, directly impacting how quickly and safely we can iterate on our technology.
This is not a traditional game development role. While the work leverages Unity and real-time 3D systems, the focus is on building scalable, production-grade systems and tools that integrate with autonomy, simulation, and data platforms. You'll take ownership of key parts of the system from CI-driven asset pipelines to real-time visualization and work closely with cross-functional teams across autonomy, infrastructure, and product.
If you enjoy working on high-impact systems, care about performance and reliability, and want to build tools that are used in real-world deployments (not just prototypes), this role is a strong fit.
This role is onsite 5 days a week at our Mountain View, CA office!
What you'll do

• Develop and extend a 3D HMI application in Unity, designed to scale with increasing system complexity and feature scope
• Build interactive user interfaces to visualize and monitor autonomous vehicle systems (e.g., perceived objects, system health, vehicle decisions)
• Design and implement scalable user interaction tools for testing, debugging, and system introspection
• Build and maintain CI/CD pipelines for Unity, including automated asset builds and content publishing (e.g., Unity Cloud Build or similar)
• Develop Unity Editor tools and scripts (C#) for asset generation, build automation, and developer workflows
• Integrate with content delivery systems (e.g., Unity Addressables, Cloud Content Delivery) for versioned asset management
• Work across the full application, building features, improving architecture, fixing bugs, and optimizing performance
• Collaborate cross-functionally with design, backend, and autonomy teams on system architecture and feature development
• Contribute to architectural decisions around content versioning, incremental builds, and runtime asset loading

What we're looking for

• 5+ years of professional software engineering experience
• 4+ years of experience with Unity and C#
• Strong experience with Unity Editor scripting (custom inspectors, editor windows, build tooling)
• Experience building and maintaining scalable systems (performance, architecture, maintainability)
• Experience with CI/CD pipelines, ideally for Unity or similar environments
• Ability to ramp quickly in existing codebases and operate independently
• Experience shipping production grade software, not just prototypes

Bonus Qualifications

• Experience with Unity Addressables and Cloud Content Delivery (CCD)
• Familiarity with network communication protocols (IPC, gRPC, UDP, etc.)
• Experience working with maps, OpenStreetMap data, or procedural 3D asset generation
• Background in real-time visualization systems (non-gaming preferred)
• Experience working in small, fast-moving teams with high ownership

Salary Ranges - $170,000- $230,000
More about Gatik
Founded in 2017 by experts in autonomous vehicle technology, Gatik has rapidly expanded its presence to Mountain View, Dallas-Fort Worth, Arkansas, and Toronto. As the first and only company to achieve fully driverless middle-mile commercial deliveries, Gatik holds a unique and defensible position in the AV industry, with a clear trajectory toward sustainable growth and profitability.
We have delivered complete, proprietary AV technology - an integration of software and hardware - to enable earlier successes for our clients in constrained Level 4 autonomy. By choosing the middle mile - with defined point-to-point delivery, we have simplified some of the more complex AV challenges, enabling us to achieve full autonomy ahead of competitors. Given extensive knowledge of Gatik's well-defined, fixed route ODDs and hybrid architecture, we are able to hyper-optimize our models with exponentially less data, establish gate-keeping mechanisms to maintain explainability, and ensure continued safety of the system for unmanned operations.
