Develop and execute sourcing strategies for chemical, mechanical, process, and other engineering roles across the company

Build targeted searches that identify exceptional engineering talent across industrial, manufacturing, materials science, and process research communities

Research, identify, and engage passive candidates through highly personalized outreach tailored to engineering disciplines

Partner closely with recruiters and hiring managers to understand technical requirements, hiring priorities, and market dynamics for engineering roles

Translate complex or evolving engineering requirements into effective sourcing strategies

Build and maintain long-term relationships with high-potential engineering candidates

Conduct talent mapping, competitive intelligence, and market research across chemical, mechanical, and process engineering fields to inform hiring strategies

Continuously improve sourcing methodologies, tooling, and recruiting processes

Track sourcing metrics and provide market insights to recruiting leaders and hiring managers

Represent Mariana Minerals through a thoughtful and engaging candidate experience

Help shape and strengthen Mariana Minerals' employer brand and engineering talent narrative

Stay current on sourcing technology, AI-assisted sourcing tools, and emerging channels to reach specialized engineering talent

Experience recruiting for industrial, manufacturing, materials, chemicals, or process-heavy environments (startup or established company)

Expert in utilizing ATS tools (preference for Ashby)

Strong expertise with LinkedIn Recruiter, sourcing tools, Boolean search, Indeed, research platforms, professional/technical societies, and other creative sourcing techniques

Demonstrated ability to identify and engage passive candidates for difficult-to-fill engineering roles

Experience partnering directly with engineering leaders and hiring managers

Excellent research skills with the ability to understand engineering domains (chemical, mechanical, process) and evaluate technical talent

Strong written communication skills with experience crafting personalized candidate outreach

Ability to manage multiple searches simultaneously while maintaining a high quality bar

Data-driven approach to sourcing strategy and pipeline management

Strong closing and negotiating skills

High ownership mindset with the ability to thrive in fast-paced, ambiguous environments

Passion for building exceptional teams and creating outstanding candidate experiences

Nice to Have

Prior experience recruiting for critical minerals, mining, chemicals, industrial automation, robotics, or deep tech companies

Experience sourcing for niche or emerging technical disciplines (e.g., materials science, controls engineering, applied AI/ML, software engineering)

Familiarity with early-stage or seed-to-Series B recruiting environments

Experience building a sourcing function or playbook from scratch

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!
