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
