Job Description
Job DescriptionAbout the Role
We're a Y Combinator-backed startup building AI-powered voice and messaging agents for enterprise call centers — automating customer service, lead qualification, and appointment scheduling at scale. Founded in 2023 and operating in a fast-moving space alongside players like Parloa, Vapi, Retell AI, and Cognigy, we're a small, high-velocity team looking for a Tech Lead to help shape our engineering foundation and take us through our next phase of growth.
This is a hands-on leadership role — you'll be writing code, making architectural decisions, and directly mentoring engineers. If you're excited about conversational AI, love building real products that ship to production, and want a clear path toward CTO-track influence, this could be a great fit.
What You'll Do
-
Design, build, and lead AI/ML systems powering voice and text-based conversational agents in production
-
Define and drive the engineering strategy, balancing short-term delivery with long-term scalability
-
Mentor and grow a team of engineers, fostering a culture of ownership, quality, and continuous improvement
-
Collaborate cross-functionally with product, research, and go-to-market teams to translate business goals into technical roadmaps
-
Advocate for and communicate technical decisions clearly to non-technical stakeholders
-
Own deployment and reliability of ML models and cloud infrastructure in a SaaS environment
-
Stay current with the latest developments in LLMs, NLP, and voice AI — and bring the best ideas into the product
What We're Looking For
Required:
-
6–10+ years of software/ML engineering experience, with a meaningful portion in leadership or staff-level roles
-
Proven experience designing and scaling AI/ML systems, ideally at a cloud-based SaaS company or high-growth startup
-
Hands-on expertise with conversational AI, voice technology, and/or NLP/LLM applications
-
Strong command of cloud platforms (AWS, GCP, or Azure) and deploying ML models to production
-
Demonstrated people management and mentorship skills — you've led engineers and driven engineering culture
-
Excellent communication skills; comfortable bridging technical and non-technical audiences
-
Must have the right to work in the United States — no visa sponsorship is available
Nice to Have:
-
Experience in call center, customer service automation, or enterprise voice platforms
-
Background at an AI-focused startup or conversational AI platform
-
Familiarity with real-time audio/speech pipelines or telephony integrations
-
Prior experience scaling an engineering team from early-stage through Series A/B
Compensation & Benefits
Compensation details will be discussed during the interview process and will be competitive with early-stage AI startup benchmarks, including equity commensurate with the Tech Lead seniority level.
Location
This role is based in San Francisco, CA. We are an in-person / hybrid team — candidates who prefer fully remote arrangements are not a strong fit at this stage. Relocation is welcome; visa sponsorship is not available.
