Software Engineer

Job Title: Software Engineer / 3D Frontend Developer (React/Three.js)
Company: The Primer (The Solar Orbital Registry Incorporated)
Location: San Francisco Bay Area (Remote) / Global Remote
About Us
At The Primer, we are building the intersection of deep-tech aerospace telemetry and gamified immersive web experiences. We are the architects behind Project Invictus, a browser-based, client-side simulation mapping the geometric anomalies of the outer solar system (Jupiter, Saturn, Uranus, Neptune). We are translating complex cosmological hypotheses (the N=I orbital resonance index) into a profound, narrative-driven digital experience.
The Role
We are looking for a highly skilled Software Engineer (Coder CS) to join our core strike team. You will work directly with our lead engineers and technical founders to accelerate the development of our interactive data-driven state machines and 3D web environments.
Because we are a lean, fast-moving startup, this role blurs the lines between research, product development, and technical execution. You will not just be writing code; you will be helping us scope product features, optimize visual rendering, and translate complex physics into seamless UI/UX transitions.
The Tech Stack
Engine: Three.js via React Three Fiber (R3F)
State Management: Zustand
Animation & UI: GSAP (GreenSock), Tailwind CSS
Post-Processing: React Postprocessing (CRT scanlines, chromatic aberration, bloom)
What You Will Do
Collaborate with our lead architect to build out the core React component trees (e.g., toggling between sterile "NASA-style" telemetry interfaces and organic "Transcendent" UI states).
Integrate data-driven state machines using Zustand to trigger massive, in-browser environmental changes without page reloads.
Optimize 3D celestial bodies, particle systems, and shader performance for seamless client-side rendering.
Assist in technical research and product roadmapping to scale the platform.
Who You Are
You have a strong Computer Science background and a proven track record of building complex, high-performance web applications.
You are highly proficient in React, modern JavaScript/TypeScript, and have hands-on experience with Three.js (or WebGL).
You are deeply curious about space exploration, orbital mechanics, and/or game design.
You thrive in an early-stage, fast-paced environment where you have high autonomy and direct input on the product vision.
Compensation & Structure
Note: We are currently in our pre-capitalization build phase.
This is a foundational role compensated via a highly competitive Sweat Equity Agreement. Approved hours logged are valued at a premium hourly rate (e.g., $50 USD/hr) and converted directly into a generous base equity grant (Subject to a global cap and standard 4-year vesting schedule with a 1-year cliff). This transitions to a formal salaried W2/contractor status immediately upon our initial capital raise.
