About the role
Oneiro builds DLX, a platform that helps financial institutions manage syndicated lending and loan administration.
We’re looking for a Product Engineer to build and deliver meaningful features, workflows, and integrations across the stack. You’ll collaborate closely with Product, Design, Engineering, and client-facing teams to turn real customer problems into pragmatic, reliable software.
You’ll independently own well-defined features through implementation, release, and production follow-up. You’ll contribute to technical decisions and progressively take ownership of larger and more ambiguous areas of work.
What you’ll do
- Build features, workflows, and integrations across the stack.
- Write clean, maintainable, well-tested software.
- Own well-defined features through implementation, release, and production follow-up.
- Turn product requirements into clear, practical technical solutions.
- Contribute to system and API design, data flows, reliability, performance, and security.
- Work carefully with financial logic, calculations, dates, state transitions, and edge cases.
- Identify assumptions and design appropriate tests for quantitative business rules.
- Work closely with Product, Design, Engineering, and customers to understand real user needs.
- Investigate production issues and raise risks or uncertainties early.
- Improve the tooling, documentation, testing, and systems you work with.
- Develop expertise in syndicated lending and loan administration.
