Job description

About Soris

We are a stealth technology company building at the intersection of foundational AI and systems design for real-world impact. Our mission is bold: to reimagine one of the largest and most entrenched industries on the planet, creating an entirely new model that is faster, fairer, and fundamentally better for humanity.

Unlike wrapper companies or point solutions, we are building a full-stack AI platform from the ground up; one that is agentic, vertically integrated, and designed for scale. This gives us the rare ability to solve problems others can’t touch, operating with orders‑of‑magnitude more efficiency than legacy systems.

Our founding team has scaled category‑defining companies in frontier tech, aerospace, mobility, and AI. We’ve led organizations from zero to multibillion‑dollar valuations, pioneered new industries, and built products that reshaped how people live and move. Now we’re assembling a small, fiercely talented team to take on our most ambitious challenge yet.

Joining us means working on cutting‑edge research with direct application, where your code doesn’t sit in a lab, it changes lives. You’ll be part of an environment that values intellectual rigor, creative rebellion, and the courage to build what others say is impossible.

This is a once‑in‑a‑generation opportunity to help design and deploy the infrastructure of the future. We’ve raised capital in record time, and are scaling our foundational team now. If you’re motivated by hard problems, high impact, and the chance to leave a legacy, we’d love to talk.

The Role

We’re looking for a Senior Software Engineer with frontend engineering expertise to join our Engineering team. You’ll work alongside the CTO and other engineers to build Soris’ first MVP. This is a ground‑floor opportunity where your work will directly shape the platform, culture, and impact of Soris.

Candidates with a good fit for this role:

• Are fluent in TypeScript/JavaScript, React, and modern web tooling
• Have extensive experience building web applications end‑to‑end
• Want to ship fast, iterate, and own outcomes.
• Thrive in ambiguity, asking questions and solving problems across the stack.
• Believe in building systems that are secure, transparent, and human‑friendly.

What You’ll Do

• Build and maintain scalable web applications using JavaScript/TypeScript, React, and related technologies.
• Create reusable UI components that will be present in all Soris applications.
• Ensure a positive user experience for all types of users, with accessibility in mind.
• Work closely with designers to translate high‑fidelity designs into polished user‑interfaces.
• Design and build core AI systems that solve real‑world problems.

Requirements

• 5+ years of experience building production web applications.
• Fluency in TypeScript/JavaScript, React, and modern web technologies.
• Experience with state management (Redux, MobX, Recoil, or similar)
• Familiarity with Restful APIs and GraphQL
• Proficiency in testing frameworks (JEST, React Testing Library, or Cypress)
• Knowledge of build tools (Webpack, Vite, Babel)

Nice‑To‑Haves

• Exposure to design systems (Figma)
• Familiarity with frontend observability (Sentry, Datadog)

Engineering Culture at Soris

Our values guide how we work:

• Extreme Ownership: We own outcomes, not just code. At Soris, we never say “that’s not my job”.
• Always Be Curious: Ask questions. Explore new ways.
• Go Farther Together: Collaboration beats silos.

Why Join Us?

• Competitive compensation package, including salary and equity.
• Benefits include employer‑covered health insurance for you, your spouse, and partially for children
• Be part of an engineering team with massive influence on product, culture, and direction.
• Work with cutting‑edge AI agents and modern tech stacks.
