Founding Engineer
$250kJeffreyM Consulting
Our client is looking for an experienced Founding Engineer to build a production-grade Voice AI legal intake platform.
This is the first engineering hire . The immediate challenge isn't simply building another AI prototype. It's taking an existing prototype and making it reliable enough for sensitive, real-world legal conversations where failures, privacy issues, or incorrect routing have meaningful consequences. The Founding Engineer will also be forward-deployed: as the founder signs law firms, this engineer will ensure the Voice AI system actually works inside each firm's environment. What You'll Do- Take an existing conversational Voice AI intake receptionist from founder-built prototype → production
- Production-grade infrastructure for live AI-powered client calls
- Embedded web-based legal intake
- Privacy and security controls for sensitive legal conversations
- Infrastructure supporting sensitive client-fund workflows
- Referral platform connecting attorneys, partner firms, and referred clients
- Telephony integrations with partner law firms
- Existing phone-system integrations
- IVR configuration/integration
- Additional AI workflows based directly on partner-firm feedback
- Reliability and production monitoring for high-stakes AI conversations
- 4+ years of professional software engineering experience
- Recent applied AI experience at a strong company
- Voice AI or telephony exposure is highly important
- Proven ability to take an AI prototype into a reliable production system serving real users
- Strong full-stack capability with ability to own the product end-to-end
- Production experience involving privacy and security
- Comfortable building workflows involving sensitive information and client funds
- Strong customer-facing ability
- Able to personally install/integrate the product into customer environments
- Comfortable working with existing phone systems and telephony integrations
- San Francisco Bay Area or willing to relocate
- Minimum 4 days/week in-office
- Comfortable with an intense founding-stage schedule beyond a conventional 9-to-5
Benefits Salary: $250,000 Equity: 10%
