Our team is a group of engineers focused on designing, building, and optimizing real-time voice solutions that power authentication, fraud prevention, and deepfake detection. We work at the intersection of advanced technology and personal security, architecting and maintaining scalable, secure voice infrastructure across SIP, VoIP, telephony systems, and cloud platforms to ensure high availability and performance. Collaborating closely with product and customer-facing teams, we deliver seamless voice-driven experiences, solve complex technical challenges, and continuously enhance our systems through automation, monitoring, and the integration of new technologies while staying ahead of emerging threats in voice security.

What you’ll do:

  • Architect and implement real-time voice solutions for authentication, fraud prevention, and deepfake detection products.

  • Collaborate closely across engineering, product, and customer-facing teams to deliver seamless voice-driven features.
  • Design and maintain robust enterprise and carrier-grade voice infrastructure supporting high-security, high-availability environments.
  • Deliver architectural improvements, optimizing for performance and onboarding new platforms or vendors.
  • Stay at the forefront of emerging threats in voice security and develop strategies to address them.
  • Use workflow automation engines, monitoring, and deployment tools to enhance system resilience and efficiency. 
  • Troubleshoot, diagnose, and resolve complex voice and networking technical issues.
  • Contribute to cross-team technical reviews and best practice dissemination.

Who you are:

  • You are resilient in the face of challenges, change, and ambiguity
  • You are optimistic and believe that you can make a problem into a solution
  • You are resourceful, excited to uncover innovative solutions, and teach yourself something new when needed
  • You take accountability, do the things you say you’ll do, under-promise and over-deliver
  • You are nimble and adaptable when priorities change and continue to see the “forest through the trees” 

Your skill set: 

  • Deep understanding of voice and data networking technologies (SIP, VoIP, PBX, IVR, SBC telephony platforms, AWS routing) 
  • Experience architecting, implementing, and scaling cloud-native voice infrastructures on AWS or Google Cloud
  • Skilled at deploying, automating, and monitoring voice platforms for reliability and performance in high-security environments (Python, Ansible, Terraform, GitHub)
  • Inclusive communicator who collaborates effectively with engineering teams, product managers, and customers
  • Demonstrated ability to provide mentorship, participate in technical reviews, and foster a company-wide culture of excellence
  • 5+ years in voice engineering or related fields; advanced degree or industry certifications a plus

What’s in it for you:

As a Pindropper, you join a rapidly growing company making technology more human with the power of voice. You will work alongside some of the best and brightest. We’re a passionate group committed to excellence - but that doesn’t stop us from enjoying the journey as a team with chess and poker tournaments, catered lunches and happy hours, wellness programming, and more. Because we take our jobs seriously, we add in time for rest with Unlimited PTO.

Within 30 days:

You’ll ramp up on Pindrop’s voice authentication, fraud prevention, and deepfake detection platforms, completing a full product and security overview. You’ll build relationships with engineering, product, and customer-facing teams to understand collaboration workflows, and review existing voice infrastructure—including SIP, VoIP, PBX, IVR, and cloud voice—to assess reliability and the security landscape. You’ll also shadow and assist in troubleshooting and resolving live technical issues to learn standard processes and tools.

Within 60 days:

You’ll drive initial architectural improvements based on your assessment findings, proposing solutions to address identified gaps. You’ll lead the integration or enhancement of a voice network component—whether hardware, software, or cloud—with a focus on scalability and security. Additionally, you’ll begin contributing to technical reviews, share best practices across engineering teams, and take ownership of platform monitoring and workflow automation tasks to improve system resilience.

Within 90 days:

You’ll deliver a strategic architectural upgrade, onboard a new voice platform or vendor, or implement a security-focused feature. You’ll proactively address emerging threats in voice security through a technical initiative or collaborative project, and demonstrate measurable impact through improvements in performance, reliability, or customer experience tied to voice solutions.
