infrastructure
Posted 1 weeks agoSoftware Engineer, Payments Infrastructure
at Sierra
San Francisco, United StatesOn-site
Responsibilities
- - Design the secure-capture protocol every channel sits behind, so the payment feels like one continuous conversation to the person on the other end, while telephony providers, contact-center platforms, embedded chat, and Sierra's own voice stack all present a single event lifecycle to agent code, no matter how different each customer's stack is.
- - Own the security perimeter around the cardholder-data environment, so what each system can reach is enforced by infrastructure rather than convention, and auditable by design.
- - Build deterministic, auditable detection in the agent's hot path that catches the cardholder data general-purpose models miss, and help design the purpose-built detection model that comes next.
Requirements
- ABOUT US At Sierra, we’re creating a platform to help businesses build better, more human customer experiences with AI.
- Previously, he was co-CEO of Salesforce (which had acquired the company he founded, Quip) and CTO of Facebook.
- Earlier, he started and led Google’s AR/VR effort, Project Starline, and Google Lens.
- Before that, Clay led the product and design teams for Google Workspace.
- The platform is PCI DSS Level 1, on Visa's Global Registry, and carries cardholder data across millions of payment lifecycle events for enterprise customers.
- - Fluency in a systems language (we use Go) and comfort owning critical distributed systems end to end, from design through production and on-call.
- You build clean abstractions and protocols over messy, inconsistent external systems, and you're never satisfied solving a problem once per customer. - Degree in Computer Science or a related field, or equivalent professional experience. EVEN BETTER… -
- Experience in a regulated or sensitive-data domain such as payments, PCI, tokenization, key management, or healthcare and PHI. - Depth in one of our core areas: applied cryptography and key management; voice, telephony, or real-time media pipelines; or cloud security and network isolation. -
- Experience building platforms other engineering teams build on, such as internal protocols, SDKs, and self-serve developer services.
- We build trust in AI by making it more accessible, safe, and useful.
- BE YOU, WITH US We're working to bring the transformative power of AI to every organization in the world.
