Principal Graphics Engineer

About Parallelz

Parallelz is building a new technology platform that enables new ways of delivering, discovering, and extending mobile applications, ways that were never thought possible. We allow developers to, with no modifications to their code, transform existing mobile apps into web-native apps that can run anywhere, all without a walled garden app store.

You will be getting in at a pivotal stage, contributing to the technical strategic roadmap, helping build a world-class technical team, and working in a small, agile, flat organization to evolve our R&D initiatives into a live, scaled operational platform that will have an impact across the industry.

Parallelz is an AI-native organization. We expect every engineer to use AI tools and agentic systems as a core part of how they design, build, debug, and ship. Not as a side experiment, but as a multiplier on judgment, velocity, and quality.

Our founding team and advisors are serial entrepreneurs and technologists from Google, Mozilla, MIT Media Labs, and other top organizations. The company is joined by top-tier and global venture funds and angel investors.

About the Role

We are seeking a passionate and resilient Principal Graphics Engineer to own a foundational piece of our infrastructure: the rendering and runtime layer that lets unmodified mobile apps execute and stream pixel-perfect, low-latency experiences to any browser.

You will spend your time deep in graphics pipelines, shaders, GPU compositing, frame timing, and the cross-stack interactions between Android/Linux graphics, browser engines, and WebGL/WebGPU. The role demands first-principles thinking, an instinct for getting to the root of difficult problems, and the maturity to ship performance-critical code that holds up at scale.

We are equally interested in candidates with a deep graphics engineering background (game engines, browser graphics, GPU systems, real-time rendering) and candidates from adjacent low-level systems backgrounds with demonstrated graphics depth.

What You'll Do

• Own the design, implementation, and evolution of our graphics and rendering stack across native (Android/Linux) and web (WebGL, WebGPU) targets.
• Write efficient, maintainable, performance-critical C/C++ for system-level and rendering components, with hard requirements on frame budgets, memory, and latency.
• Profile and tune the full pipeline: CPU/GPU bottlenecks, shader cost, texture and buffer management, compositor interactions, and end-to-end streaming latency.
• Investigate and resolve faults in complex environments, tracing issues from the browser engine down through the runtime to the OS, kernel, and graphics driver.
• Drive upgrades to the underlying platforms (AOSP versions, browser engines, GLES/WebGPU evolution) while keeping the system stable and shippable.
• Partner with other teams to define and implement robust testing strategies for rendering correctness, performance regressions, and cross-device fidelity.
• Operate as a senior independent contributor: scope your own work, drive it to completion, and communicate clearly with a small, high-trust team.
• Work natively with AI coding agents and tooling (Claude Code, Cursor, agentic workflows, custom internal agents) to accelerate research, prototyping, code generation, debugging, and review, treating these tools as a junior pair you direct and verify, not a passenger.
