We’re reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.\nThe role\nMariana Minerals is looking for a Sr. or Staff Software Engineer, Infrastructure to join the team that owns and collaborates on the platform every other engineer here builds on.\nOur software team builds MarianaOS, the operating system for how Mariana engineers, constructs, and operates its mines and mineral processing facilities. It runs in AWS and on edge clusters at our sites, including our copper site in Moab, Utah and our lithium facility in East Texas. On any given day, it serves construction dashboards, running GPU inference on site camera feeds, training models for a lithium extraction circuit, and moving plant floor data into a warehouse.\nYour team owns the platform underneath all of that: clusters, deployment, CI/CD, observability, site/edge footprint, identity, secrets, and cloud costs. You will also collaborate with machine learning engineers and data engineers on the ML compute platform and data pipeline infrastructure.\nThe part of this role we care most about is what you build for other people. We do not want an approval queue. When an engineer needs a database, a bucket, a dashboard, or an alert, they should get it from a documented path they can run themselves, and your job is to make that path exist and make it the easiest option. You will be measured on how much infrastructure work happens without you.\nWe move quickly. Our engineers ship, get feedback from the people running our plants and job sites, and iterate. Everything you build should shorten that loop.\nOur stack is TypeScript and React on the front end, Node and Python services, Postgres, and AWS. The platform is EKS with Karpenter, ArgoCD, Helm, Pulumi, Prometheus and Grafana, Loki, Prefect, Snowflake, and a growing amount of LLM and agent tooling in production.\nWhat You'll Do\nOwn our Kubernetes footprint end to end: the EKS cluster, the on-premises site clusters, cluster upgrades, capacity and autoscaling, ingress and DNS, and the GitOps delivery path that turns a merged commit into a running service.\nBuild self-service infrastructure for other engineers, so that provisioning a service, a database, a preview environment, or a scheduled job is a documented path they run themselves so the team can deliver quickly.\nMake observability a default. Every deployed service should emit metrics, ship logs, trace requests, and carry meaningful alerts without its author's writing bespoke plumbing.\nExtend the platform to our sites, running on-premises and edge clusters that host GPU inference and plant data collection over constrained links.\nOwn cloud cost as an engineering problem, with the visibility, budgets, and right-sizing to keep a growing platform from growing its bill proportionally.\nOwn identity, access, and secrets management, so that scoped access is provisioned and revoked as a matter of course.\nRespond to infrastructure incidents and then remove the class of failure that caused them, including writing the runbook so the fix scales.\nWhat You'll Bring\n8-12+ years building and operating production infrastructure, with real depth in Kubernetes: you have run and upgraded clusters yourself and debugged multiple layers below the application.\nStrong software engineering fundamentals. You write code you would be comfortable having reviewed by a product engineer, and you reach for a well-designed tool or abstraction before a runbook.\nHands-on experience with infrastructure as code (Pulumi, Terraform, or similar) and GitOps-style continuous delivery.\nA track record of building platforms other engineers adopted willingly. We will ask you for specifics: what you built, who used it, and how you know it helped.\nPractical observability experience with Prometheus, Grafana, and a log aggregation stack, and getting an organization to instrument its services.\nComfort operating across a broad surface with incomplete context.\nFluency in Python or TypeScript, and enough familiarity with AWS to make sound cost and architecture tradeoffs.\nExperience supporting ML or data-intensive workloads (GPU scheduling, distributed training, pipeline orchestration) is a strong plus.\nExperience with on-premise or edge infrastructure, industrial networks, or constrained-connectivity environments is a strong plus.\nStartup experience in a rapidly scaling company is helpful but not required.\nDomain experience in manufacturing, industrial automation, mining, or capital projects is beneficial but not required.\nHow We'll Interview\nWe want to see you design and build platform tooling, so the loop is weighted toward that.\nExpect a conversation about a platform you have built and why you made the calls you made, a working session where you design a self-service capability for an engineering org and we push on the tradeoffs, and a hands-on exercise with infrastructure code.\nOur culture is built on four principles:\nEveryone Gets Home Safe. We never put speed or cost ahead of people.\nExtreme Ownership. We take full responsibility for outcomes, relentlessly driving toward solutions.\nEngineer Out Requirements, then Automate. We simplify, optimize, and then automate for scale.\nShare Your Legos. We collaborate openly, share knowledge, and empower each other to build bigger, better solutions.\nJoin us as we build the future of responsible mineral sourcing and supply!","description_format":"text","description_chars":5642,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Mining","Mining Tech","Non-ferrous Metals"],"lifecycle":[{"event":"open","at":"2026-10-06T00:40:05Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 15","filings_12m":15,"filings_prev_12m":2,"green_card_filings_12m":0,"median_offered_wage_usd":152500,"route":null,"cap_exempt":false,"checked_at":"2026-10-03T21:08:04+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":3}],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":6,"expected_fill_days":38,"reasons":["conf:3","stale_co","velocity","win:early"],"computed_at":"2026-10-12T06:55:09Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/mariana-minerals-sr-software-engineer-infrastructure","json_url":"https://alion.io/job/mariana-minerals-sr-software-engineer-infrastructure.json","meta":{"generated_at":"2026-10-12T12:50:25Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":20058,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":8004},"rest":"https://alion.io/mcp/rest/get_company?id=8004"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmariana-minerals-sr-software-engineer-infrastructure"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fmariana-minerals-sr-software-engineer-infrastructure"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fmariana-minerals-sr-software-engineer-infrastructure"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/mariana-minerals-sr-software-engineer-infrastructure\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmariana-minerals-sr-software-engineer-infrastructure"}]}
