About the team
People Intelligence sits within People and Communications. We build the data and products behind talent decisions at every level — from leaders, managers, and employees. Our partners in Total Rewards, HRBP, Talent Management, and People Operations depend on what we ship..The team is a growing team, and you will help set the engineering standard for how we build.
In this role, you'll have the opportunity to:
Lead technical projects from first design through launch and iteration, across products such as performance cycles, compensation planning, talent reviews, total rewards statements, and self-service tools.
Design scalable architectures that integrate with our internal systems (i.e. Workday, Ashby, etc.) and our people data platform, that holds up when the whole company is in a review or compensation cycle.
Build with security in mind from the first commit, including role and reporting-line access, protection for compensation and performance data, and an audit trail on every change.
Work directly with Total Rewards, HR business partners, Talent Management, and People Operations to understand how each program runs, transforming it into products that managers and employees want to use.
AI is native to you, and speeds up how you design, build, and test, to help the team adopt the workflows that hold up.
Raise the technical bar through design reviews, code review, documentation, and mentorship.
Skills you bring:
5+ years of professional software development, with a track record of building internal tools and production systems that employees and teams depend on every day.
Full-stack experience building web applications, with depth in at least one of Ruby, Python, TypeScript, or Kotlin, and a modern frontend framework such as React.
Experience designing systems that handle sensitive data, including authentication, fine-grained authorization, and auditability.
Clear communication with non-technical partners, and the product judgment to simplify a complex process rather than rebuild.
Experience taking a product from 0 to 1, including making architectural calls with incomplete information and revisiting them as you learn.
Nice-to-have's:
Experience building HR or people products, such as performance management, compensation planning, talent management, or employee self-service. We value this domain depth highly.
Experience integrating with an HRIS such as Workday, including its APIs and effective-dated data and other HR related systems (i.e. Ashby, Lever, Shareworks, Okta, etc.)
Familiarity with how people programs run, including review and calibration cycles, compensation bands and merit planning, and job architecture.
Experience in a regulated or privacy-sensitive environment.
Who you are:
You are self-directed, and you find the next problem worth solving without waiting for a ticket.
You are curious about how things work, and you ask why a process exists before you change it.
You treat employee data with care and think about privacy and access as design constraints from the start.
You would rather ship a simple version, learn from real users, and improve it than hold back a perfect one.
You own outcomes, not just code, and you stay with a product after it launches.
You make the people around you better through pairing, reviews, and clear writing.
