CultureSmith is proud to partner with Arcobi in the search for a new Senior Full Stack Engineer. This is a high-impact senior role ideal for someone who thrives in dynamic, growth-stage environments.

About Arcobi

Arcobi (formerly Arcus Power) is at the forefront of the global shift towards electrification and low-carbon power systems. Their AI-driven Energy Cost Management platform is revolutionizing power management by enabling users to optimize operations based on electricity prices, peak demand periods, and market opportunities. Originally a tech startup in Calgary, Arcobi is now expanding globally.

Their diverse team of data scientists, software developers, electrical engineers, and market analysts are committed to creating intelligent models that support efficient energy resource consumption.

Arcobi fosters a collaborative, innovation-driven, and dynamic culture, where everyone's input is valued.

Role Overview

Arcobi is seeking an exceptional Senior Full-Stack Engineer who combines technical excellence with a passion for crafting beautiful, intuitive user experiences. You’ll build enterprise-grade applications where visual appeal meets best-in-class functionality—creating interfaces that energy market professionals and Fortune 500 companies rely on to optimize electricity usage and integrate renewable energy.

This role is for someone who believes that enterprise software doesn’t have to be ugly. Working closely with their product team, you’ll architect modern React applications with TypeScript that are as delightful to use as they are technically robust. If you obsess over details—from component architecture to the perfect button hover state—and want your work to accelerate the clean energy transition, this is your opportunity.

What You’ll Build

Modern Frontend Applications

• Build responsive, pixel-perfect React applications using TypeScript
• Create reusable component libraries and design systems (Storybook)
• Implement sophisticated data visualizations using D3, Visx, or Recharts
• Design and maintain a cohesive design system with careful attention to typography, color, and spacing
• Partner with product and design to deliver production-ready features
• Ensure exceptional performance and accessibility across all interfaces
• Design and implement RESTful APIs using FastAPI and Python
• Build microservices architectures for real-time data delivery
• Implement robust authentication, authorization, and security practices
• Create background jobs and data processing pipelines
• Ensure system reliability through testing and monitoring

End-to-End Ownership

• Ship features from concept to production, across frontend and backend
• Collaborate with designers to refine user flows and interactions
• Integrate ML models and analytics into user-facing features
• Participate in code reviews and mentor other engineers
• Contribute to architectural decisions and technical direction

Your Qualifications

Must Have

• 5-7+ years of full stack experience building production applications
• Expert-level proficiency in React and TypeScript
• Strong backend experience with Python and FastAPI
• Proven track record building polished, user-friendly UIs
• Experience with component libraries and design systems
• Proficiency with state management (Redux, Tanstack, Context API, Zustand)
• Experience with SQL and NoSQL databases
• Strong grasp of RESTful API design and microservices architecture
• Familiarity with modern build tools (Vite, Webpack, etc.)
• Experience with Git workflows and CI/CD pipelines

Highly Valued

• Experience with data visualization libraries (D3.js, Visx, Recharts, Plotly)
• Proficiency with Storybook for component development and documentation
• Background in building enterprise SaaS applications
• Experience with Figma and translating designs to production-quality code
• Experience with Mantine component library and styling approaches
• Familiarity with testing frameworks (Vitest, React Testing Library, Playwright)
• Knowledge of Python ecosystem (Pydantic, SQLAlchemy, async patterns)
• Understanding of time-series data and real-time analytics interfaces
• Background in performance optimization and lighthouse scores
• Experience with design tokens and theming systems
• Contributions to open-source projects or component libraries
• Craft & Polish: You sweat the details and deliver pixel-perfect implementations
• User Empathy: You think deeply about user workflows and UX impact
• Systems Thinking: You design components and APIs for reusability and maintainability
• Ownership: You ship complete features, deliver customer value, and stand by the reliability and availability of your work, not just crunch through tickets
• Collaboration: You work effectively with designers, product managers, and engineers
• Pragmatism: You balance perfection with shipping and know when “good enough” is right
• Communication: You articulate technical decisions and can advocate for users

How to Apply

This is your chance to build beautiful, powerful applications that drive the energy transition. If you're a craftsperson who believes enterprise software can be delightful, if you care deeply about both code quality and user experience, and if you want your work to have real climate impact—Arcobi wants to build this with you.
