About the role
We're looking for a Backend Engineer with 5+ years of experience building production systems who brings a strong combination of Python backend engineering, security expertise, and hands-on AI/agentic systems experience. You should be comfortable owning infrastructure and security-critical features end-to-end in a fast-moving, early-stage environment, and have a track record of shipping systems that meet enterprise-grade security requirements. Bonus points if you've been a founding or early engineer at a startup.
Responsibilities
- Architect and build core backend systems from scratch with a focus on reliability, scalability, and security — this is greenfield work reporting directly to Dioptra's founders
- Design and implement security-critical features such as customer-managed encryption keys (BYOK), secure data handling, and access controls for enterprise customers like Microsoft, J&J, and Mercedes-Benz
- Own and drive enterprise security compliance efforts including SOC 2 audit implementations, controls, and infrastructure hardening
- Build and deploy AI-powered agents and systems in Python to automate complex contract workflows
- Manage and scale cloud infrastructure (AWS or Azure), including DevOps-adjacent work around deployment, monitoring, and securing AI agent architectures
- Translate ambiguous product requirements into concrete technical systems and shipped features, working directly with customers and internal stakeholders to unblock deals
- Establish engineering best practices, tooling, and culture as an early member of a small, high-impact team
