About Rubypoint

What We Do

We're building next-generation digital manufacturing technology that's already backed by several Fortune 500 companies whose names you would instantly recognize. These industry leaders are investors who believe in our vision and are committed to our success.

Our Culture

We're a scrappy, mission-driven startup founded by deeply technical leaders with extensive industry experience and connections. We believe technical excellence starts with assembling an exceptional team, and we're building that team right now. If you want to work alongside world-class engineers who are obsessed with solving hard problems, this is your opportunity.

Team & Growth

You'll be joining at the founding stage of our startup. The engineers we hire now will form the core of our technical team for years to come. This is your chance to get in on the ground floor and help shape the future of digital manufacturing from day one.

Work Environment

This role will start fully remote but will transition to in-office work in Belgrade as we establish our office. Eventually, we'll offer hybrid flexibility (1-2 days remote per week). We value in-person collaboration for building a tight-knit, high-performing team. You'll work closely with teammates and customers primarily in the US and Europe, so expect regular collaboration across time zones.

Role Overview

You'll take our prototype web application and transform it into a polished, production-ready user interface that Fortune 500 companies depend on daily. This means building React components that scale, writing clean frontend code that lasts, and making critical UI/UX decisions that will shape our product for years to come. As we grow to 20+ engineers, you'll naturally step into leadership, mentoring new hires and setting the technical standard for backend engineering.

What you'll build: The frontend of a collaborative web platform that revolutionizes how manufacturers handle product data from initial design through production to final quality control. You'll work primarily in React + TypeScript, creating stunning Three.js 3D visualizations and intuitive user interfaces. You'll integrate with our Go backend via REST and gRPC APIs, ensuring seamless data flow and exceptional user experiences. This isn't just another CRUD app. You're building the future of digital manufacturing.

Responsibilities

• Shape product architecture: Drive technical decisions and system design discussions that define our platform
• Build and ship features: Take ownership of front-end features from concept to production
• Evolve the codebase: Refactor, optimize, and improve existing systems for scale and maintainability
• Ensure quality: Write comprehensive tests and maintain high code standards
• Elevate the team: Participate in code reviews and help establish engineering best practices
• Drive visibility: Communicate progress and technical decisions to stakeholders
• Collaborate across functions: Work closely with product and design to deliver exceptional user experiences
• Work globally: Partner with team members and customers across US and European time zones

Requirements

• DevOps basics: Git, Docker, CI/CD pipelines, front end testing (e.g., Jest, Playwright, Cypress)
• Passion for learning and building systems from scratch
