Projects

About PerkUpPerkUp is an employee rewards and recognition platform. We help companies celebrate their people — birthdays, anniversaries, peer recognition, performance milestones, holidays — without HR teams drowning in logistics. We also run a global swag platform that lets companies design, store, and ship branded merchandise to employees and customers anywhere in the world.We're a scrappy startup making a big bet: a small team that uses AI tools well can outship competitors 10x our size.

You'll design and ship features across our platform — rewards delivery, recognition workflows, analytics, the developer infrastructure that keeps us shipping fast, and the many third-party integrations that hold it all together (HRIS, payroll, Slack, Stripe, shipping carriers, swag suppliers, and more).

What you'll do

• Build and operate systems on Firebase, Cloud Run, BigQuery, and our integrations layer
• Own meaningful surface area: design, implement, test, deploy, operate
• Use AI development tools well, and help raise the team's effective ceiling with them
• Review code, mentor mid-level engineers, raise the bar
• Partner with product to find simpler solutions before building
• Write clear RFCs and PRs that move decisions forward
