About the role

As the first HR Generalist on the Transport & Mining HR team, you'll work directly with the Head of HR for Transport & Mining to build the people foundation for two fast-scaling businesses. This role is designed for someone with 3-5 years of HR experience who wants to grow in employee relations, manager coaching, data-driven HR, and operational excellence.

You'll support employees and managers across a diverse workforce: engineers and operations teams in San Francisco, manufacturing technicians, and hourly field teams at customer sites in the US and internationally. You'll own day-to-day HR operations, keep our people data accurate, ensure compliance, and help deliver the people programs that let these teams scale. Your job is to help us move from reactive to proactive while the organization is still being built.

The ideal candidate brings a service mindset, exceptional attention to detail, and sound judgment in a fast-paced environment. You'll be equally comfortable supporting an engineer in HQ and a technician on a shift schedule.

What you’ll do

Employee Relations & Manager Coaching

• Serve as the first point of contact for employee and manager questions across Transport & Mining, providing guidance on HR policies, benefits, leaves, and local requirements.
• Handle employee relations intake, documentation, resolution tracking, and trend spotting, and partner with Employee Relations on investigations and complex cases.
• Coach managers on performance, conduct, and attendance issues, including coaching conversations, documentation, and performance improvement plans.
• Coach new and first-time managers on everyday people practices, and help build simple resources they can use on their own.

HR Operations & Compliance

• Own onboarding and offboarding for a high volume of employees across office, field, and manufacturing roles, from HRIS setup, background checks, and site readiness to termination entries, final pay, and system deactivation.
• Process job changes, transfers, and pay changes with high accuracy, and keep employee data clean as T&M teams move onto Atoms' core HR systems.
• Partner with Payroll on timekeeping audits for hourly and shift-based employees, including overtime and premium pay, and help make sure roles are classified correctly as exempt or non-exempt.
• Coordinate workers' compensation claims from intake to resolution with operations, safety, and insurance partners, and conduct regular audits across HR focus areas to ensure ongoing compliance and operational accuracy.
• Support M&A integration efforts, including employment agreements, benefits transitions, and onboarding into Atoms programs and systems.

Business Partnership & People Programs

• Partner with engineering, operations, and manufacturing leaders on org changes, team health, and headcount planning, bringing data and a point of view to the conversation.
• Help deliver Atoms' people programs for Transport & Mining, including performance cycles, engagement, recognition, and retention.
• Support leveling and title consistency as teams grow and new teams join Atoms.

Data, AI & Process Improvement

• Build and maintain reporting on headcount, hiring, attrition, attendance, and leave trends, and turn the data into clear and actionable insights for HR leadership and business leaders.
• Find repetitive HR work and remove it, using AI tools, automation, templates, and self-serve resources.
• Turn one-off fixes into simple, repeatable processes that will hold up as we scale.

What we’re looking for

• 3-5 years of HR experience, ideally as an HR Generalist in logistics, transportation, manufacturing, or a high-growth start-up.
• Bachelor's degree preferred, or equivalent combination of education and experience accepted.
• Experience supporting hourly, field, or manufacturing employees across multiple US states, including exempt vs. non-exempt classification. International exposure is a plus.
• Proficient with or the ability to quickly learn payroll management, human resource information system (HRIS), and similar computer applications. Workday experience is a plus.
• Strong analytical skills: comfortable with spreadsheets, building reports, and pulling insight from HRIS data.
• Hungry and builder-minded: you've worked without a playbook, figured it out, and stayed with a problem until it was fixed. You're comfortable with ambiguity and speed while holding a high bar for quality.
• Excellent interpersonal skills with the ability to manage sensitive and confidential situations with tact, professionalism, and diplomacy.
• Clear, confident communication skills, both written and verbal.
• Organized and detail-oriented, with a deep care for doing great work. You raise the bar for yourself and others.
• AI-fluent and already using new tools to work faster and improve HR processes at scale.
