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.
