Mariana Minerals; San Francisco (CA); On-site; USD 180,000 - 240,000; Full time

Job summary

Mariana Minerals is seeking an Engineering Manager to build and lead a software team responsible for MarianaOS, the operating system that powers its mines and processing facilities. You’ll own performance management, hiring, career development, and delivery against roadmap commitments, while staying technically engaged and mentoring engineers.

The role involves coordinating with tech leads, product managers, and operations to ship reliable software quickly and to continuously improve management

Qualifications

• 3-5+ years managing software engineers directly, including performance management, career development, and hiring.
• 8+ years in software with the depth to make sound tradeoffs alongside strong Tech Leads and senior engineers.
• You can review a design or a change you didn’t write, spot the flaw, and give feedback that makes the engineer better.
• A track record of teams delivering predictably under real deadlines, with estimates and commitments stakeholders learned to trust.
• Demonstrated success growing engineers through promotions, expanded scope, and increasing ownership.
• Strong experience translating between non-technical stakeholders and engineering teams, including communicating technical constraints clearly.
• A bias toward shipping and learning from feedback rather than waiting for a complete plan.
• Experience bringing structure to ambiguous, fast-moving problems.
• Startup experience in a rapidly scaling company is helpful but not required.
• Experience in manufacturing, industrial automation, mining, or capital projects is beneficial but not required.

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.
