About the role

Engineering Manager to build and lead a team of software engineers working on MarianaOS, the operating system for Mariana Minerals’ mines, processing facilities, and data systems. Focus on delivering reliable software for the critical minerals supply chain with close collaboration across engineering, product, operations, and site teams in Moab, Utah and East Texas.

Responsibilities

  • Build and lead a team of software engineers, owning 1:1s, feedback, performance reviews, career development, and compensation input and advocacy.
  • Own the hiring funnel for your teams, from sourcing and interviewing through closing and onboarding, shaping the team's mix of skills, seniority, and ownership as it grows.
  • Deliver predictably against roadmap commitments. Give Product a counterpart who can say what is technically possible, how long it will take, and what it will cost in schedule or reliability, and give Product, Operations, and leadership early warning when something is slipping.
  • Create the conditions for the team to ship quickly and iterate from real feedback, working directly with the engineering, construction, and operations teams who use what you build.
  • Break down ambiguous problems, sequence the work, and keep the team unblocked, using a planning cadence that fits how the team operates.
  • Partner with your Tech Lead and senior engineers on technical direction, staying close enough to the architecture to maintain a high bar.
  • Build a resilient team by growing engineers into larger scope, addressing morale and conflict early, and reducing critical dependencies on any one person.
  • Run the team's review, documentation, and ownership practices so the work survives the person who built it.

Qualifications

  • 3-5+ years managing software engineers directly, including performance management, career development, and hiring.
  • 8+ years in software, with the technical depth to make sound tradeoffs alongside strong Tech Leads and senior engineers.
  • Ability to review designs or changes you didn’t write, identify flaws, and give constructive feedback.
  • Track record of teams delivering predictably under real deadlines, with trustworthy estimates and commitments.
  • Demonstrated success growing engineers through promotions, expanded scope, and increasing ownership.
  • Strong experience translating between non-technical stakeholders and engineering teams, clearly communicating technical constraints.
