About Mariana Minerals

Mariana Minerals is a software-first, vertically integrated minerals company on a mission to supply the critical minerals powering modern energy, AI, and defense technologies. We’re reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.

Role Overview

Mariana Minerals is looking for a highly motivated Full Stack Software Engineer to work on building the critical minerals supply chain to support the world’s energy transition.

As a Full Stack Software Engineer at Mariana Minerals, you will lead the development and deployment of software to accelerate the engineering and construction of physical infrastructure that is critical to building the minerals supply chain. Responsibilities will include building integrations with the existing software tools for engineering and construction, extending these tools to fill in gaps and address pain points identified by Mariana’s internal engineering and construction teams, working with Mariana’s ML engineers to integrate LLMs to tackle specific challenges around unstructured data ingestion and understanding, and working with Mariana’s internal teams to develop a new “operating system” for the engineering, construction, and operation of Mariana’s mineral processing facilities.

What You’ll Do

Work closely with Mariana’s internal engineering, construction, and operations teams to identify and build internal software tools to accelerate the deployment of Mariana’s mineral processing facilities.

Build data integrations with the existing suite of engineering/construction tools such as Autodesk.

Build net new web experiences and applications that will be used by Mariana's internal teams and partners to help build capital project faster and more efficiently.

Evaluate existing software in the ecosystem to assist Mariana’s internal teams

Work closely with Mariana’s ML engineers to implement novel LLM powered experiences that assist Mariana’s internal teams.

Assist with the data architecture for Mariana’s data pipelines to feed the training of novel ML models that control Mariana’s mineral processing facilities and provide visibility into the operation of the facilities to the internal Mariana team.

What You’ll Bring

Strong understanding of software engineering in a professional capacity (1.5+ years preferred).

Ability to work with non-software stakeholders to identify pain points and needs, scope level of effort required for new features, and then drive implementation of these features.

Self-starter mindset, ability to bring clarity to high ambiguity situations, and excitement to work with non-software stakeholders directly.

Ability to work across the entire stack from deploying servers to writing front end code and everything in between (or demonstrated proficiency in one of these areas and the desire to expand your skillset).

Our culture is built on four principles:

Everyone Gets Home Safe. We never put speed or cost ahead of people.

Extreme Ownership. We take full responsibility for outcomes, relentlessly driving toward solutions.

Engineer Out Requirements, then Automate. We simplify, optimize, and then automate for scale.

Share Your Legos. We collaborate openly, share knowledge, and empower each other to build bigger, better solutions.

Join us as we build the future of responsible mineral sourcing and supply!
