About Bond
Bond is a fast-growing startup on a mission to break down communication barriers between Deaf and hearing individuals by making personalized, high-quality sign language interpretation effortlessly accessible to everyone, anywhere. Our rapid growth has allowed us to raise an additional recent round of funding, which now supports our plans to quickly expand our product offering. 
Our first product, BondVRS, reimagines Video Relay Service (VRS), a critical service for the Deaf community. With a single click, Deaf users can instantly invite highly-skilled interpreters to any video platform — our proprietary Zoom-like platform or any mainstream platform (e.g. Zoom, Google Meet, Teams, Webex, FaceTime, and WhatsApp).
As a user-focused team passionate about technology, accessibility, inclusion and bridging communication gaps, we’re looking for like-minded people. If you thrive in innovative, fast-paced environments, are curious to deeply understand the diverse needs of our rapidly growing userbase, and have the mindset to reimagine an industry, you’ll fit right in at Bond.
About the Role
We are seeking a Staff WebRTC/SIP Engineer to build the real-time infrastructure that makes video communication instant and reliable—partnering with full-stack engineers to deliver platform capabilities that power exceptional user experiences. The ideal candidate will bring deep expertise in media processing, distributed systems, and reliability engineering.
This work directly impacts the Deaf community's ability to communicate effectively—when our systems fail, users can't connect with interpreters. Someone who treats reliability as a craft and takes pride in systems that work under pressure will be uniquely positioned to thrive in this role.
What you'll be doing
Build Infrastructure That Never Fails: Design and implement highly-available, fault-tolerant backend services that power real-time video communication. When a Deaf user needs an interpreter, your systems must connect them instantly and reliably—every single time.Scale Real-Time Communication Systems: Own the backend infrastructure that handles video routing, session management, call state, and integration with third-party platforms. You'll make architectural decisions that enable Bond to grow from hundreds to hundreds of thousands of concurrent calls.Enable Frontend Teams Through Platform Excellence: Build the APIs and services that frontend engineers depend on to deliver great user experiences. You'll design intuitive contracts, provide clear documentation, and ensure your platform is a force multiplier for the team.Deliver Operational Excellence and Observability: Instrument what matters, establish SLOs that reflect user impact, and build systems that surface problems before users notice. You own uptime—incidents, post-mortems, and continuous improvement.Contribute to a Purpose-Driven, User-Centered Culture: Understand how platform decisions impact real users, advocate for reliability in technical discussions, and connect your work to our mission of improving access and communication for the Deaf community.
Requirements
Proven Backend Engineering Skills: 10+ years building, deploying, and operating backend services in production. You've been on-call, responded to incidents, and learned from scaling systems over time.Real-Time Media Processing Expertise: Hands-on experience with GStreamer (required), SIP/RTP, and WebRTC. Familiarity with SFU media servers (we use Janus). You understand the challenges of processing audio and video in real-time at scale.Expertise in Highly-Available Systems: Deep understanding of distributed systems, fault tolerance patterns, and reliability engineering. You can articulate real-world tradeoffs between consistency and availability, and design systems that handle partial failures gracefully.Detail-Oriented and Data-Driven: You instrument your systems, use metrics and logs to diagnose issues systematically, and make architectural decisions based on evidence. You distinguish signal from noise when systems are under stress.Startup Adaptability: You thrive in ambiguous environments, build with incomplete requirements, and make sound engineering tradeoffs under uncertainty.
Preferred experience
Connection to the Deaf Community: Strong awareness of Deaf culture and accessibility needs is a major plus; personal or professional experience with the Deaf community is ideal.API/Platform Design: Track record of designing APIs or internal platforms that other engineering teams build on.
