Job summary

Ultra Security is seeking a Staff Engineer to bridge Applied AI and security infrastructure, owning end-to-end delivery across frontend/backend/services. You’ll design scalable systems, enforce runtime policies, and collaborate on AI-adjacent architecture while moving fast in a security-conscious environment.

You will influence architecture, drive reliability, and partner with teams to ship secure, auditable solutions at scale.

Qualifications

• 5+ years building and shipping production software.
• Staff/Principal/Founding-level trajectory or equivalent scope.
• Strong backend/infra/distributed systems background.
• Security product experience including authz/audit/logging.
• Experience with AI tooling adjacency and eval/reliability thinking.
• Experience in startup or high-velocity environments (Seed–Series C).

Responsibilities

• Build product and infrastructure end-to-end (frontend + backend) and ship polished user-facing workflows.
• Own modules from 0 to 1 and 1 to n: scope, design, implement, launch, iterate.
• Partner with the team to keep the product simple and fast while meeting security/compliance.
• Turn customer feedback into concrete improvements with ship-measure-learn loops.
• Operate with a bias to action and make pragmatic tradeoffs when needed.
• Build and evolve the core security platform: runtime enforcement, guardrails, auditability, visibility.
• Design for latency, reliability, debuggability, and clear operator UX.
• Leverage AI tools (Claude, Codex, Cursor, MCPs) to move faster while preserving correctness.
• Contribute to evaluation and reliability thinking so new capabilities are testable and non-regressive.
