Freelance Full Stack Developer Jobs in British Columbia

Saltworks Technologies is a leading Canadian cleantech company solving two of the world's most pressing challenges: water sustainability and critical minerals supply. We design and build advanced industrial water treatment and lithium refining systems for global leaders in semiconductors, mining, automotive, and industrial processing.

Saltworks is a 2025 Technology Fast 50 company and EY Entrepreneur of the Year award winner. We lead our industry in adopting and developing AI across our products, projects, and operations. Join us and build skills defining the next era of engineering and industrial systems.

The role:

Saltworks is seeking a Full-Stack Developer to expand the Data Systems team. You will build the tools, integrations, and data infrastructure that power Saltworks engineering and operations. Working closely with system owners and department leads, you will translate business requirements into working software, from front-end interfaces to back-end services, secure API endpoints, and AI-powered applications.
This is an on-site role at our office in Richmond, BC, with limited opportunity for remote work. You must be located in or be willing to relocate to the Lower Mainland.
Key responsibilities:

• Design and build full-stack internal tools to support engineering and operational workflows.
• Build integrations between enterprise systems by consuming application APIs and creating secure API endpoints to transport data.
• Build and support data pipelines that move, transform, and surface operational data across systems.
• Leverage AI tools and LLM-based agents to accelerate development and extend the capabilities of internal systems.
• Work closely with system owners and non-technical stakeholders to translate business requirements into working solutions.
• Write clean, well-documented code and participate in code reviews to maintain quality standards across the team.
• Apply a security-first mindset by writing defensively, handling data with care, and building systems that are robust and maintainable.
• Troubleshoot, debug, and resolve issues across the full stack.
• Proactively identify opportunities to improve existing workflows through automation or better tooling.

You will be a great fit if you have:

• 3–5+ years of hands-on full-stack development experience, with a proven track record of shipping production software.
• A degree in Computer Science, Software Engineering, or equivalent practical experience.
• Comfort with JavaScript/TypeScript, at least one modern front-end (Handlebars, React, Vue, Angular, etc.), and one back-end framework (NestJS, NodeJS, etc.).
• Proficiency in Python for back-end development and data manipulation.
• Experience with relational databases: T-SQL or PostgreSQL, including query optimization and data modeling.
• Experience building and consuming REST and SOAP APIs.
• Familiarity with Git, Docker, and CI/CD fundamentals.
• Exposure to cloud services in AWS (EC2, Lambda, Secrets) or Azure (VMs, Functions, Key Vault).
• A working familiarity with AI tools: you use them daily and understand their limitations (hallucinations, data privacy, access controls).
• A collaborative, self-directed work style – you can scope a problem, execute independently, and communicate progress clearly.
• Bonus: experience with Databricks/PySpark, PowerShell/Bash scripting, PHP, C#/.NET, message queues, prior work with ERP or PLM systems, and hands-on experience building or integrating AI agents.
