The Role

We’re seeking an HR Business Partner to play a key role supporting Sigma’s technical organization. You’ll work with engineering leaders across Software Engineering, Infrastructure, AI, Product, Design, and Security to shape how a fast-growing technical org is structured, led, and developed, to support the goals of the business. You’ll also stay hands-on in running the people programs behind that work.

This role and Sigma’s culture suit someone who moves easily between strategy and execution. One day you might advise a VP on changes to their org design, and the next you’re working through a sensitive employee relations issue. You’ll bring your experience and learnings to figure out what works at Sigma, rather than reusing a past playbook.

Please note, this role is on-site four days per week in our San Francisco office, located in the Financial District.

What You'll Do

• Work with technical leadership to translate priorities into people plans that support and enable teams to execute on their goals and roadmap.
• Partner with leaders on org design work, team dynamics, and leadership effectiveness. Flag talent risks and opportunities early, using data to inform your insights and recommendations.
• Coach managers through sensitive situations, including performance issues, team dynamics, and employee relations. Run investigations with Legal when needed.
• Own core people programs for your business areas: performance/talent reviews, compensation cycles, employee engagement, and talent development. Run each one with both operational rigor and business context, from the first proposal through communication and rollout.
• Partner with Talent, People Ops, and Legal to build programs that reflect your client groups’ needs, and keep leaders informed about changes that affect their teams.
• Use AI tools, including Sigma itself, to reduce manual work and speed up insight in recurring people processes.

What We're Looking For

Required:

• 5+ years of progressive HRBP experience, including significant time supporting engineering or other technical teams at a high-growth software company.
• Broad HR expertise across performance management, employee relations, org design, talent development, and compensation.
• Experience advising senior engineering leaders at the VP level and the ability to influence decisions in ambiguous, high-stakes situations.
• A working understanding of how engineering organizations scale, including team structures, career ladders, and the people challenges that come with fast growth.
• Comfort with data: you can pull together people metrics, spot trends, and turn them into a recommendation leaders will act on.
• Sound judgment that balances business outcomes with employee experience, risk, and long-term scalability.
• Strong written and verbal communication, including facilitating groups and leading difficult conversations at every level.
• Working knowledge of US employment law and immigration processes and experience partnering with legal counsel to manage risk.
• Hands-on experience using AI tools to make HR work faster or better.
