About Biostream
At Biostream, we're building the infrastructure that will power the next generation of battlefield medical intelligence. Our platform combines physiological data, AI, and operational intelligence to improve survivability in the world's most demanding environments.
About the Role
We're looking for an exceptional engineer to architect and build our next-generation Trusted Research Environment: a secure, AI-native platform where sensitive medical data, foundation models, and researchers can work together safely.
This is not a traditional infrastructure role. We are looking for someone who is obsessed with modern AI tooling and can move at the pace of today's AI ecosystem while applying the engineering discipline required for highly secure environments.
What you'll build
- Design and implement our AI-native Trusted Research Environment from the ground up.
- Build secure compute environments for training, evaluating, and deploying AI models.
- Create infrastructure that enables researchers to analyze sensitive data without exposing or exporting it.
- Architect permissions, audit logging, identity management, and secure collaboration.
- Integrate modern AI tooling, coding agents, and developer workflows into a secure platform.
- Work closely with our AI and product teams to ensure our infrastructure accelerates, rather than restricts, innovation.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What we're looking for
We're far more interested in exceptional engineers than specific degrees. Ideally, you'll have experience with many of the following:
- Designing secure cloud platforms on Azure or AWS.
- Kubernetes and container orchestration.
- Infrastructure as Code (Terraform or similar).
- Identity and access management.
- Secure software development practices.
- Modern AI infrastructure including LLM deployment, vector databases, model serving, and GPU workloads.
- AI-assisted software development.
- Python and backend engineering.
- CI/CD and modern DevSecOps pipelines.
- Experience working in regulated, healthcare, defense, or other high-security environments.
Get help with your application
Your very own career expert that helps elevate your application to the next level.
You'll thrive in this role if you...
- Constantly experiment with the newest AI tools and development workflows.
- Believe AI-assisted engineering is now the default way to build software.
- Care deeply about elegant architecture rather than unnecessary process.
- Can balance rapid iteration with enterprise-grade security.
- Enjoy solving difficult systems problems that have never been solved before.
- Want to own an entire platform rather than maintain someone else's.
Nice to have
- Experience building Trusted Research Environments or secure data platforms.
- Experience with confidential computing, secure enclaves, or air-gapped deployments.
- Knowledge of ISO 27001, SOC 2, or healthcare security standards.
- Experience supporting AI or machine learning teams.
- Familiarity with medical, defense, or research environments.
