Java Holdings Ltd. owns a portfolio of companies and provides high-level execution support for large utility, oil and gas, and power generation projects, with a focus on EPCM (Engineering, Procurement, Construction & Management) services. We are seeking a motivated, detail-oriented Developer to join our growing software development team in the Edmonton or Calgary area.

In this role, you will independently deliver high-quality software features, support production systems, and help configure business-critical workflows and integrations. You will work within established architecture and engineering standards while contributing practical ideas to improve quality, reliability, and team effectiveness.

This position is designed for a mid-level developer with 3-5 years of professional experience who is comfortable taking ownership of assigned work, collaborating with technical and business stakeholders, and escalating risks or design gaps when needed.

What You'll Do

Develop and deliver assigned front-end components, back-end services, APIs, and application features.
Write clean, maintainable, secure, and well-documented code in accordance with team standards and established architectural patterns.
Create and maintain automated tests to support solution quality and reliable releases.
Troubleshoot and resolve defects, production issues, and application performance concerns.
Participate in peer code reviews, sprint planning, refinement, testing, and release activities.
Work with React, C#/.NET, RESTful APIs, Entity Framework Core, Microsoft SQL Server, and PostgreSQL.
Configure internal and external systems to meet documented project requirements, including complex business rules and digital quality documentation.
Configure integrations using approved tools, patterns, and standards, and escalate gaps or new integration needs to senior technical resources.
Collaborate with stakeholders to understand requirements, identify implementation considerations, and support User Acceptance Testing.
Maintain technical documentation and provide system training or user guidance when required.
Communicate risks, blockers, and concerns promptly while adapting to evolving requirements and priorities.

What Success Looks Like

Consistent delivery of reliable, maintainable features that meet documented requirements.
Effective participation in code reviews, technical discussions, and team planning.
Accurate system and integration configuration using approved tools and patterns.
Prompt communication of risks and steady growth in technical and business knowledge.
Positive contribution to production stability, documentation quality, and overall team effectiveness.

Why Join Us

Join a growing core development team building and improving business-critical internal systems.
Work on meaningful operational challenges across construction execution, workforce processes, integrations, reporting, mobile workflows, and platform modernization.
Develop your skills through collaboration with experienced developers, technical leadership, and business stakeholders.
Contribute to a team culture that values accountability, learning, practical problem-solving, and coding excellence.
Receive a competitive salary and benefits package.

Requirements

3-5 years of professional software development experience.
Proficiency in JavaScript and React for front-end development.
Experience with C# and .NET for back-end development.
Strong SQL skills and hands-on experience with PostgreSQL and/or Microsoft SQL Server.
Experience building or supporting RESTful APIs and modern web applications.
Experience using Entity Framework Core or a comparable object-relational mapping framework.
Strong troubleshooting skills and experience supporting production systems.
Ability to understand how application components, services, integrations, and data fit together.
Ability to independently deliver assigned features while following technical direction and established standards.
Clear communication, sound judgment, attention to detail, and effective collaboration skills.
Comfort working in a fast-paced, deadline-driven environment with changing priorities.
Ability to travel internationally for site visits and system rollouts when required.

Nice to Have

Integration development experience, including system-to-system data flows and scheduled processing.
Experience with Hangfire or a similar background job scheduling framework.
Knowledge of CI/CD pipelines, source control practices, and DevOps workflows.
Experience with personnel management, employee record, occupational health and safety, or construction-tracking systems.
Experience in construction, infrastructure, electrical utility, oil and gas, or power generation environments.
Experience with SharePoint 2019 or later, document control systems, mobile workflows, GIS, scheduling, or material management solutions.
