Company Description: Overtone - Founded by the creator of Hinge and backed by Match Group.

Job Description:

As the second engineering hire at Overtone, you will build the foundational backend and ML infrastructure for a revolutionary voice-first dating experience. Working directly with the founder of Hinge, you'll design fault-tolerant systems and real-time architectures that move beyond the swipe to facilitate genuine, AI-enhanced human connections.

Location: New York, USA

Why this role is remarkable:

• Exercise complete technical ownership over 0→1 systems including ML pipelines, model serving infrastructure, and real-time voice streaming architectures.

• Work in-person with a high-caliber NYC team to disrupt the dating industry by solving ""swipe fatigue"" through sophisticated AI and human psychology.

What you will do:

• Design and build the core backend infrastructure for a consumer-facing product focused on real-time voice interactions and low-latency user experiences.

• Develop production-grade ML infrastructure, including feature stores and evaluation systems, to power high-trust matchmaking and conversational chemistry.

• Establish engineering standards and make critical architectural tradeoffs while implementing robust security and privacy-by-design principles for sensitive user data.

The ideal candidate:

• Proven experience as a Senior Backend or Systems Engineer building and scaling consumer products from 0→1 in a fast-paced environment.

• Strong expertise in real-time or streaming technologies such as WebRTC, along with experience managing LLM-powered features and model lifecycles.

• Demonstrated ability to design fault-tolerant, production-grade systems with a deep commitment to high-quality craft and pragmatic, intentional engineering.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
