At Pro Service, we exist to empower employers to succeed in Hawai?i. More than 3,000 local businesses rely on us for payroll, HR, and benefits, and many run their day on tools like Toast, Quick Books Online, and Net Suite. When those systems talk cleanly to ours, a restaurant owner closes payroll without re-keying hours. When they don’t, a small business loses time it doesn’t have.

This role owns that connection. You’ll build and run the integrations marketplace that links our customers’ business systems to our HR platform, blending strong engineering with real product ownership. Success looks like customers connecting in minutes, data that stays accurate without manual work, and problems fixed before anyone has to report them.

Design, build, and launch integrations with platforms like Toast, Quick Books Online, and Net Suite using OAuth 2.0, webhooks, and polling

Own the integrations marketplace end to end, including the catalog, connect and disconnect flows, connection health, and a roadmap prioritized with Product

Architect reusable serverless patterns on AWS (Lambda, Event Bridge, SQS, DynamoDB) in Python, Type Script, and React/Next.js so each integration ships faster than the last

Partner directly with customers on bespoke integrations with Pro Service APIs, and with vendor developer programs on sandbox access, certification, and API changes

Build monitoring and alerting that catches sync failures before customers notice

Uphold code quality through testing, code reviews, and CI/CD, and support production reliability through on-call rotations

This is an ownership role, not a ticket queue. You’ll ship at least one production-ready integration per quarter and keep owning it after launch, including joining the on-call rotation to resolve critical issues within hours. You’ll also talk directly with customers and partners to shape what gets built next. These expectations are not optional — they’re the job. You’ll share them with a team that reviews each other’s code and treats incidents as chances to learn, not to assign blame.

The role also takes patience. Partner APIs change, certifications move at their own pace, and many decisions are judgment calls between fast and durable. The team works on Hawai?i Standard Time, so Southern California candidates should expect a workday that starts mid-morning and runs into the early evening.

You’ve shipped production-grade software in a SaaS or product-driven environment, and you’ve built third-party integrations that stay reliable. That means experience with OAuth 2.0 token lifecycle, webhooks, pagination, data mapping, and vendor API versioning.…
