Responsibilities

  • ● OUR PRODUCT TEAM
  • ● Our current Product team consists of multiple squads that autonomously own the full lifecycle of the product, pushing it from discovery to production. You'll work together with other experienced engineers, PMs, and the CTO to deliver on an exciting product roadmap.
  • ● The tech stack at Payflip to achieve this consists of multiple modern technologies https://www.notion.so/payflip/Payflip-s-Tech-Stack-1debf70bee8680349354e099802af72e pvs 4. Where core components in our stack are:
  • ● Node.js (NestJS) & TypeScript
  • ● PostgreSQL + Prisma ORM
  • ● REST/OpenAPI with generated SDKs, GraphQL at the edges
  • ● Azure + Terraform (Container Apps, VMs, networking, Key Vault)
  • ● Windows Server, SQL Server & IIS
  • ● We value bringing eagerness & skill in building mature & maintainable solutions with a great DX more than an exact overlap with our tech stack. Experience in all of them is not a must, but willingness & autonomy to learn definitely is.
  • ● THE PAYROLL SQUAD
  • ● You'll join our Payroll squad, building Payflip's own payroll engine: a greenfield backend service that connects the Payflip platform to the world of Belgian payroll. That means:
  • ● Designing robust APIs and data models for payroll concepts like workers, absences and payslips.
  • ● Building reliable integrations with external payroll systems - asynchronous processing, queues and idempotent syncing.
  • ● Running part of our stack on Windows Server VMs in Azure (SQL Server, IIS, Remote Desktop), fully provisioned with Terraform.
  • ● Working in a domain where correctness and auditability matter: it's people's salaries.
  • ● ABOUT YOU
  • ● You would be a good fit with our team if most of this sounds like you:
  • ● Strong backend engineering skills: API design, relational data modeling, transactional integrity, async job processing (queues, outbox pattern, idempotency)
