Staff Software Engineer (Authentication)

Who We Are Pindrop is a cybersecurity company delivering continuous identity verification across voice, video, and digital interactions. Powered by the Pindrop Intelligence Network, our unified trust platform helps enterprises answer three critical questions: Is this identity synthetic? Detect AI-generated and manipulated voice and video. Is this identity risky? Identify fraud, suspicious behavior, and other risk signals. Is this identity known? Authenticate identities using voice, device, behavioral, and other signals. Pindrop brings this intelligence together across purpose-built trust engines to help organizations make informed decisions in real time — protecting customers, workforce interactions, and emerging AI-driven interactions. Pindrop protects billions of high-risk interactions for enterprises, including leading financial institutions, insurers, and healthcare organizations. Its technology is informed by more than 8 billion real-world interactions annually and protected by 300+ patents. Recognized by TIME as one of the 10 Most Influential Software Companies of 2026 and by Inc. for Best in Business for Innovation, Pindrop is backed by leading investors including Andreessen Horowitz, IVP, and CapitalG. As a Staff Software Engineer on the Authentication team, you will set technical direction for the cloud services and infrastructure behind Passport, guiding the team through its continued migration to the cloud platform. You will operate beyond a single service or sprint, leading complex, multi-quarter initiatives that improve the reliability, scalability, performance, and security posture of Authentication's systems. This is an individual contributor role with broad technical influence and no direct people-management responsibility. You will partner closely with engineering leaders, product, test and research to shape architecture, resolve systemic risks, and turn ambiguous problems into durable solutions. More specifically, you will: Define and evolve the technical strategy and architectural direction for Passport's cloud services, spanning multiple subsystems and workflows. Lead high-impact, ambiguous initiatives from problem framing and design through implementation, rollout, and operational follow-through, using Go and Python. Set technical standards and reusable patterns for cloud-native services across AWS and GCP, including services such as Kinesis, DynamoDB, and S3, with a focus on reliability, scale, and secure production operation. Make and communicate consequential tradeoffs involving reliability, scalability, latency, security, cost, and time to market. Anticipate systemic risks, identify architectural gaps, and drive mitigation before they affect customers, delivery velocity, or operational stability. Partner closely with software engineering, test engineering, research, product teams to align roadmaps and deliver new capabilities. Lead technical reviews and facilitate alignment on complex design…
