A message from the founder
Why I built OIS, where we are now, and the kind of engineer I'm looking for to help build what comes next.
- Where OIS is today
- Who I'm looking for
- Why this could be the right opportunity for you
Why this role matters
The platform exists. Now we're building what comes next.
Build Real Products
Build applications and vertical products on top of OIS that solve real problems.
Shape the Engineering Organization
As OIS grows, this role can grow with it into broader technical leadership and responsibility.
The role: Senior Full-Stack Engineer
What you'll own
- OIS SDK development and maturation
- Full-stack application development
- APIs and integrations
- Backend services
- Database architecture
- Product interfaces
- Testing and observability
- Deployment and production support
- Documentation and developer experience
You'll also work with the founder on
- Platform hardening
- Architecture discussions
- Technical problem solving
- Runtime testing and instrumentation
- Future platform capabilities
What we're looking for
Technical ability
Strong experience with some combination of:
- Python
- TypeScript
- React / Next.js
- PostgreSQL
- APIs / SDKs
- AWS / Cloud
- Testing
- Observability
How you think
- You trace problems before patching symptoms.
- You can work inside an existing architecture without immediately trying to rewrite it.
- You distinguish assumptions from evidence.
- You can challenge technical decisions constructively.
- You're comfortable with ambiguity.
- You take ownership.
- You can explain complex systems clearly.
- You use AI aggressively without outsourcing your judgment to it.
How we work
Small team. High ownership. Direct communication.
Work directly with the founder
No layers of management between the problem and the person building it.
Understand before changing
OIS has an existing architecture. Learn why something exists before replacing it.
Ship, inspect, improve
We value working software, evidence, testing, and iteration.
AI is part of the workflow
We expect engineers to use modern AI development tools intelligently while remaining accountable for what they ship.
Compensation & opportunity
Highly competitive compensation.
We're prepared to pay competitively for the right person. For exceptional long-term contributors, there is also a path to meaningful equity after we've established mutual fit.

A résumé tells us what you've done.
We also want to understand how you think.
Our application is intentionally different. We'll ask about systems you've built, difficult problems you've solved, how you approach unfamiliar architecture, and how you use AI in your work.
There aren't trick questions, and we're not looking for rehearsed answers.
