React Developer

We are looking for a React Developer for a 12-month contract position, with possible extensions in Calgary, Alberta. Must be legally entitled to work in Canada.

This position is 100% onsite in downtown Calgary. 8 hours a day, 40 hours a week. It is NOT a remote role.

Role Description

The React Developer will work on a data-intensive internal operations platform used by engineers and operators. The frontend supports workflows, approvals, monitoring, and decision-making tied to real-world systems. This role is well-suited to someone who enjoys complex data and visualizations, clear UX, and collaborating closely with backend engineers.

Responsibilities

• React UI for dashboards, tables, and workflows
• Turn complex domain concepts into clear, usable UI
• Forms and review flows (approve / reject / override)
• Data-dense views where accuracy and clarity matter
• APIs that are event-driven and change over time
• Work closely with backend engineers on API shape and UI behavior
• Geospatial mapping, plots and advanced visualizations

Required Skills and Experience

• An undergraduate Computer Science Degree or equivalent work experience
• Strong experience with React
• TypeScript in real production codebases
• Experience managing server state (React Query, Redux Toolkit, Zustand, etc.)
• Proven ability to design usable interfaces, not just implement specs
• Comfortable working with large, structured datasets
• Solid understanding of async UI behavior (loading, retries, partial failure)

UI / UX Expectations

• Good visual and interaction judgment (spacing, hierarchy, affordances)
• Ability to design intuitive workflows for non-technical users
• Experience working without a dedicated designer
• Willingness to iterate on UX based on real user feedback
• Focus on clarity and usability over visual flair
• Formal design training is not required, but practical UX experience is.

Desired Skills and Experience

• React Query or similar data-fetching libraries
• Data-heavy UIs (tables, filters, operational dashboards)
• Internal tools or enterprise applications
• Collaboration on API design and data contracts
• Uplot, plotly, deck.gl, AG Grid, vis-timeline, D3, or other visualization tools
• Tailwind CSS
• Experience with industrial, energy, or operations software is nice to have
• Exposure to event-driven systems is nice to have
