Vielight is building an AI-powered neurotechnology platform for clinicians and researchers. As a full stack engineer you will be building and debugging features from end to end across React and Python. You'd also own our AWS infrastructure as code and the security of our applications.

This is a hands-on development role, not a dedicated DevOps or IT administration position. Expect roughly [half] of your time on product features and the rest on cloud infrastructure and security.

What you'll do

- Build, debug and ship features from end to end: React front end, Python (Django) back end, REST APIs, PostgreSQL, and background jobs with Celery/RabbitMQ.
- Own our AWS infrastructure as code with Terraform or AWS CDK: ECS, RDS, S3, networking and IAM, with every change reviewed and version-controlled.
- Build and maintain GitHub Actions pipelines for testing and deploying to development and production.
- Security-test our own applications (authentication, access control, APIs, the OWASP Top 10), fix what you find, and coordinate external penetration tests and the fixes that follow.
- Implement and maintain the technical safeguards that support HIPAA and PHIPA compliance: least-privilege access, encryption, secrets management, audit logging and backups.
- Help integrate LLMs through Amazon Bedrock with appropriate protection for sensitive data.
- Set up the monitoring, logging and alerting we need, and keep an eye on cloud costs.




- Document what you build and share knowledge with a small team.

What we're looking for

- Skilled experience building production web applications with React and Python (Django, Flask or FastAPI).
- Hands-on infrastructure-as-code experience (Terraform or AWS CDK) on real AWS environments.
- Working knowledge of core AWS services: IAM, VPC networking, ECS or other container services, RDS/PostgreSQL and S3.
- Comfort with Docker, Linux, Git and CI/CD (GitHub Actions or similar).
- Application security fundamentals: the OWASP Top 10, authentication and authorization, handling secrets and sensitive data, and experience finding and fixing vulnerabilities.
- Enjoys debugging across the whole stack, from the browser to the database to cloud configuration.
- Works independently and writes clear documentation.

Nice to have

- Celery, RabbitMQ or Redis
- Penetration-testing tools such as Burp Suite or OWASP ZAP, security certifications like OSCP or AWS Security Specialty, or capture-the-flag experience
- Experience with healthcare data or PHI, or with HIPAA, PHIPA or SOC 2
- Building applications on Amazon Bedrock or other LLM platforms
- React Native
- AWS certifications
