Our voice-based platform conducts natural, personalized interviews at scale—so hiring teams can quickly surface the best candidates, without spending hours on phone screens. The product is live, early customers are using it, and we’re backed by Andreessen Horowitz (a16z Speedrun), NEA, and other top-tier investors. Now we’re hiring our Founding Engineer to help us take Ezra from early traction to breakout growth. ## The Role As Ezra’s first full-time engineering hire, you’ll partner directly with the CEO to own the architecture, engineering strategy, and technical execution across the entire product. You’ll work across the stack—from real-time voice AI systems to intuitive front-end interfaces—and help lay the foundation for the team, codebase, and culture as we grow. This is a unique opportunity to join a funded, post-MVP startup and build a product that’s already in use with real customers. ## What You’ll Do - Lead engineering end-to-end—backend, frontend, infra, and DevOps. - Prototype and integrate voice AI pipelines (ASR → intent classification → LLM → TTS). - Make foundational decisions about architecture, infrastructure, and tooling. - Collaborate with the CEO to shape product roadmap and execution. - Build toward a system that supports high-volume hiring and tight feedback loops. - Establish engineering practices (testing, monitoring, CI/CD, etc.) from the ground up. - Help hire, onboard, and mentor the early engineering team. ## What We’re Looking For - 9+ years of experience building production systems. - Fluency in Node.js, React, TypeScript, and Python. - You've shipped and scaled real products, ideally at fast-moving startups. - You’re excited about AI and voice interfaces, and have worked with LLMs or similar tools. - You’re scrappy, self-directed, and love working across product and engineering. - You thrive in ambiguity and know how to balance shipping fast with technical debt. Bonus Points - Experience with voice AI tools - Familiarity with voice streaming pipelines, transcription services, or audio processing. - Prior experience as a founding engineer or early technical hire. - Background in recruiting tech, HR tech, or conversational interfaces. Work Environment - Fully remote, with core collaboration hours in Pacific Time - Small, focused team where your work is immediately impactful - Momentum: real users, real feedback, real opportunity to shape what Ezra becomes ## About ezraailabs.tech ## Company Overview - **One-liner**: Ezra AI Labs builds a voice AI interviewing platform that conducts structured, on-demand conversations to screen candidates fairly and efficiently. - **Entity Type**: Private (acquired by Greenhouse Software in May 2026) - **Headquarters**: San Francisco, California, United States - **Founded**: 2024 - **Founders**: Ophir Samson (CEO & CTO) ## Core Business - **Primary industry**: HR Technology / Recruitment Software / AI Voice Interviewing - **Target customers**: B2B — recruiting teams and HR departments at companies of all sizes (SMB to Enterprise) - **Mission / purpose**: “To surface fair, explainable talent signals through structured AI voice interviews, giving recruiters time to focus on people, and giving candidates coaching and feedback to thrive.” ## Products & Services - **Ezra Voice AI Interviewer**: AI-powered voice interview platform that integrates with Applicant Tracking Systems (ATS) to automate initial screening. Recruiters define questions and rubrics per role; every candidate answers the same questions and is scored objectively. The platform provides transcripts and explainable evaluations. Available as a standalone product (even after Greenhouse acquisition). ## Market Standing - **Valuation / Market Cap**: Not disclosed (private, acquired by Greenhouse; acquisition terms not public) - **Key Metrics**: - Annual Revenue (2025): ~$440K (estimated, pre-acquisition) — [getlatka.com](https://getlatka.com/companies/ezraailabs.tech) - Total Funding: $3.2M (Seed round, March 2026) — [linkedin.com](https://linkedin.com/company/ezraailabs) - **Notable Investors / Partners**: LMNT Ventures (lead), Penny Jar Capital (lead), a16z Speedrun; now part of Greenhouse Software - **Growth Signals**: - Acquired by Greenhouse in May 2026, signaling strong product-market fit and strategic value - Headcount grew ~200% YoY (from 1 to 3 employees) - Founder Ophir Samson joined Greenhouse as Head of Voice AI to lead integration ## Competitive Advantages - **Structured, explainable AI**: Every candidate gets the same questions and is scored against a pre-defined rubric — unlike black-box AI screening tools. - **Built by recruiters, for recruiters**: The team has firsthand recruiting experience, leading to a product that solves real pain points. - **Acquisition by Greenhouse**: Provides immediate scale, distribution, and credibility in the HR tech ecosystem. - **Bias transparency**: Monthly independent bias audits published publicly on the Greenhouse AI Assurance Dashboard. ## Strategic Focus - **Integration with Greenhouse**: Deepening the voice AI capability across Greenhouse’s interviewing, talent matching, and candidate experience modules. - **Expansion beyond US**: Currently available in the US, with additional regions planned. - **Standalone product growth**: Continuing to serve non-Greenhouse customers and other ATS integrations. ## Why Work Here - **Culture**: Small, mission-driven team (3–4 people) focused on making hiring fairer and more human. “Recruiting is an art” — the company emphasises augmenting recruiters, not replacing them. - **Remote/Hybrid**: Based in San Francisco, but roles appear to be remote-friendly (a recent Sales role was listed as “Remote – United States”). - **Notable perks**: Ownership of high-impact projects post-acquisition; working directly with the founder (now Head of Voice AI at Greenhouse); exposure to a fast-growing category. - **Engineering culture**: Typescript, React, Python, Greenhouse API integration; a focus on building scalable, explainable AI systems. ## Sources 1.
